When comparing the N95 or N99 respirator mask, both are designed to protect workers from dust and airborne particles that can become airborne. The primary difference between the two is that the N95 respirator can only be used for particles of size one micron or smaller, while the N99 respirator mask can be used for particles up to one micron in size. So, what is the difference?

The difference between the materials used in N95 Mask and N99 Mask

The primary difference between the N95 particulate respirator mask and the N99 respirator mask is that the N95 respirator mask is a one-piece that is generally constructed of nylon with a Velcro closure and mask straps. This is a fairly simple design compared to an N99 particulate respirator mask, which can either be a one-piece mask, or a two-piece mask or a three-piece mask. The N95 particulate respirator mask also has a Velcro closure.

The N95 particulate respirator mask is constructed of a nylon polyester blend material that is relatively lightweight compared to the N99 particulate respirator mask which is made of a polyester powder coated nylon that is typically constructed of polyester and is heavy-duty. This powder coating of polyester allows for greater resistance to dust and airborne particles compared to a polyester composite material.

However, another important difference between the two is that the nylon polyester powder coated nylon material of the N95 respirator is more durable than the N99 particulate respirator mask. This means that if the nylon polyester powder coated nylon material is accidentally punctured during the workwear, the puncture does not allow for easy passage of air or dust particles into the wearer’s lungs.

On the other hand, the polyester composite material of the N95 particulate respirator mask can be easily punctured by particles of dust and air that can still pass through the polyester composite material into the wearer’s lungs. The nylon polyester powder coated nylon material can be easily punctured by a tiny air piece that can become airborne, or even a hairpin, which is a small metal object that can become airborne.

The difference between N95 Mask and N99 Mask to resist harmful substances

While the N95 is designed to protect against particles of dust and airborne particles, the N99 respirator masks can also protect against chemical vapors. The N99 respirator masks can be used for chemical vapors that are toxic to the eyes, nose, and throat such as benzene vapors, hydrogen sulfide, and chlorine vapors.

While both types of masks are designed to protect against dust and airborne particles, the N95 respirator mask can also protect against chemicals. However, the N95 particulate respirator mask is designed to be a one-piece mask, which is not as good for chemical protection as the N99 particulate respirator mask, because a small air piece can become airborne and go through a part of the nylon material on the mask during the wear. The N95 particulate respirator mask is designed to provide a more complete airtight fit and is less vulnerable to punctures.

The N95 respirator is also easier to use than the N99 respirator mask in that it is much easier to use, while still maintaining a one-piece design that prevents air leakage. When purchasing an N95 particulate respirator mask, it is important to keep in mind that the N95 respirator mask is more durable and less prone to punctures, so that it can be used for more hazardous situations such as chemical vapors.

The N95 respirator is also lighter, which makes it easier to carry and use for more hazardous situations. Both types of masks are designed to be lightweight and provide a more complete fit.

There are some situations in which the N95 particulate respirator mask is not the best choice of protection. If a chemical is involved and you are not a medical professional or are not knowledgeable about the proper use of a protective respirator, it is important to wear the appropriate one or to call for professional help.

It is also important to check the expiration date of a mask, and ensure that the replacement date is not past the expiration date. of a particular mask before wearing one.

N95 mask refers to the mask that passed the US NIOSH standard, but do you know how to pass it?

1. What is American NIOSH?

The National Institute of Occupational Safety and Health (NIOSH) works at the Centers for Disease Control and Prevention (CDC), a federal agency that specializes in generating new knowledge in the field of occupational safety and health and turning that knowledge into practice to improve workers.

Because personal protective equipment (PPE) plays an important role in keeping many workers in various industries safe during their duties, the National Personal Protection Technology Laboratory (NPPTL) was established as a department of NIOSH to prevent disease.

To accomplish this mission, NPPTL conducts scientific research, develops guidance and authoritative recommendations, disseminates information, and responds to the requirements of workplace health hazard assessment.

Under the authorization of the Occupational Safety and Health Act of 1970, the National Institute of Occupational Safety and Health (NIOSH) provides a test, approval, and certification program to ensure that the respirator used in the workplace meets the standards of 42 CFR Part 84.

Since 1994 NIOSH has maintained a searchable online version of the list of certified equipment.

NPPTL was established in 2001 at the request of Congress. The laboratory was created to meet the recognized need to improve personal protective equipment (PPE) and focus on personal protection technology (PPT).

2. N95 face mask US NIOSH certification requirements

According to the NIOSH guidelines, the enterprise needs to send samples to the NIOSH laboratory for testing, and submit technical information (including some quality system information) to the NIOSH document review. Only after the document review and test pass, NIOSH will issue the approval.

NIOSH classifies its certified anti-particulate masks into 9 categories, and specific tests are performed by NPPTL (National Personal Protective Technology Laboratory) laboratory under NIOSH.

The main test indicators include exhalation resistance test, exhalation valve leakage test, inhalation resistance test, and filtration efficiency test.

3. N95 face mask NIOSH certification standard:

National Institute of Occupational Safety and Health (NIOSH) New Standard for Dust Respiratory Protection 42CFR84

4. Introduction of FDA mask certification

N95 face mask

The N95 face mask that has been approved by NIOSH can be directly registered by the FDA.

According to updated data from the US Food and Drug Administration (FDA), as of April 13th, masks produced by 62 manufacturing plants in China have obtained FDA emergency use authorization (EUA), including such as KN95, ZK601 meets the Chinese national standards for a class of masks with particulate filtering efficiency.

Some industry sources said that obtaining the FDA’s emergency use authorization only represents that the mask is allowed to enter the United States, and American hospitals still recognize the masks that have obtained NIOSH certification.

Class II (special control) of surgical gowns and surgical masks. If the N95 surgical face mask or N95 filter face mask respirator is designed to prevent specific diseases or infections, or is marked or otherwise expressed as filtering surgical smoke or fumes, filtering a specific amount of viruses or bacteria, reducing the following diseases Quantity and/or killing viruses, bacteria or fungi, or affecting allergenicity, or including coating techniques not related to filtration (eg, reducing and/or killing microorganisms).

Surgical N95 respirators and N95 filter-mask respirators are not subject to the premarket notification procedures in Section E of Section 807 of this chapter, but subject to the following conditions of 878.9:

(i) It must be demonstrated that the components of the user’s contact with the device are biocompatible.

(ii) Analytical and non-clinical tests must:

(A) It is flammable and proved to be suitable for the intended use environment;

(B) Demonstrate the ability of the device to resist the penetration of fluids (such as blood and body fluids) at a rate consistent with the intended use of the device.

(iii) NIOSH is approved according to its regulations.

(2) Class I (conventional control) of surgical apparel other than surgical gowns and surgical masks.

5. U.S. entry requirements for masks and other anti-epidemic products:

Masks: The United States also manages medical masks and protective masks separately. Medical masks are managed by the US Food and Drug Administration (FDA), and personal protective masks are managed by the National Institute of Occupational Safety and Health (NIOSH).

Medical masks: Medical masks need to be registered with FDA, and companies apply directly to FDA and submit relevant materials.

There are two alternative ways:

1. N95 masks that have obtained NIOSH registration can be exempted from product registration (510K) when the product biological test, flame retardant test and blood penetration test pass, and directly carry out FDA factory registration and medical device listing.

2. If authorized by a manufacturer holding 510K, it can use its 510K approval number as its foundry for enterprise registration and device listing.

Personal protective masks: protective masks need to be registered with NIOSH, and companies apply directly at NIOSH.

6. N95 NIOSH-approved masks

The N95 face mask is one of 9 anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health).

“N” means not suitable for oily particles (oil fumes produced by cooking are oily particles, and the droplets generated by people talking or coughing are not oily);
“95” means that the filtration efficiency reaches 95% under the test conditions specified in the NIOSH standard. N95 is not a specific product name. As long as it conforms to the N95 standard and has passed the NIOSH review, it can be called the “N95 face mask”.

Masks are divided into 9 categories. The specific certification is operated by the NPPTL (National Personal Protective Technology Laboratory) laboratory under NIOSH.

According to the filtering characteristics of the middle filter of the mask, it is divided into the following three types:
N series: N stands for Not resistant to oil and can be used to protect non-oily suspended particles.
R series: R stands for Resistant to oil and can be used to protect non-oily and oily suspended particles.
P series: P stands for oil Proof and can be used to protect non-oily and oily suspended particles.
According to the low filtration efficiency of the filter material, the mask can be divided into the following three levels:
95 grade: indicates that the low filtration efficiency is 95%.
99 grade: indicates a low filtration efficiency of 99%.
100 grade: indicates a low filtration efficiency of 99.97%.

The appearance of COVID-19 makes face masks a daily necessity in our lives. For face masks, we often hear n95 face masks, kn95 face masks, and surgical face masks. There is an approved standard for n95 face mask in the United States, do you know?

What are N95 NIOSH-approved masks?

Particulate respirators are designed to help reduce the wearer’s exposure to airborne particulate hazards.
In the U.S., respirators are tested and certified by the U.S. National Institute of Occupational Safety and Health (NIOSH). NIOSH tests and certifies respirators based on their physical and performance characteristics, including filtration efficiency.

For example, N95-rated filtering facepiece respirators have a filtration efficiency of at least 95% against non-oily particles when tested using the NIOSH criteria. The particles used to test the filtration area in a size range that is considered the most penetrating.

Therefore, the test methods ensure that the filter media can filter particles with at least 95% efficiency.

FDA-Cleared Surgical Masks

Surgical masks are cleared for use as medical devices by the U.S. Food and Drug Administration (FDA), or equivalent agencies outside the U.S., and are designed to be worn by healthcare professionals during surgical procedures.

That clearance is based on data and proposed claims provided by the manufacturer to the FDA for review, in which the FDA evaluates and then “clears” those products that meet their requirements. Because surgical masks are meant for use during surgeries, a key performance requirement is a fluid resistance – the ability of masks to resist penetration by high-pressure streams of liquid, such as those that might result from a human artery being punctured during surgery.

Additional information about the differences between surgical masks and N95 respirators cab be found in the NIOSH infographic Understanding the Difference Between Surgical Masks and N95 Respirators.

Surgical N95 Respirators

Surgical N95 respirators are both approved by NIOSH as an N95 respirator and also cleared by the FDA as a surgical mask.

These products are frequently referred to as medical respirators, healthcare respirators, or surgical N95s. Comparing Standard N95s to Surgical N95sPutting this all together will help you differentiate between a standard NIOSH-approved N95 respirator and a surgical N95 respirator. While similar in appearance, the key difference is the fluid resistance and the resulting FDA clearance of surgical N95s.

N95 NIOSH-approved masks selection guide.

Protecting yourself from toxic fumes is important, and using the correct respirator is one of the best ways to protect yourself. NIOSH respirator masks are one of the most common choices when purchasing a respirator.

Protecting yourself from particulate matter and another hazardous chemical and biological material is important, but only a respirator that meets or exceeds the required standards can help you do this. Unfortunately, the masks that are currently available are not as effective as they could be. The various versions of the NIOSH respirator masks are not a good choice for all situations.

When buying an N95 Niosh approved mask, it is important to consider several factors. The mask should offer protection against the dust, smog, smoke, fumes, and various chemicals that the user may encounter in the workplace. It should also provide protection from the airborne particles that are often released from the operator’s body and face when the user moves around. The operator should feel safe and comfortable when wearing the mask.

The size of the respirator is important. It should fit properly. The person wearing the NIOSH respirator should feel like the mask fits them well. The airtight seal that the mask provides is another factor that needs to be considered.

When choosing a respirator, consider whether you will need multiple types of filters. There are specific NIOSH respirator masks that can filter out gases such as carbon dioxide, particulates, hydrogen sulfide, and sulfur dioxide. A respirator like this is particularly useful for protecting workers in certain hazardous industries.

If you are a heavy smoker or you will be exposed to second-hand smoke, you may want to consider using an air filtering respirator. The air filtration allows the lungs to receive oxygen, while the filter does its job. The benefits of using these types of respirators are important to consider.

When shopping for NIOSH approved masks, keep in mind that the manufacturer should be certified by the agency. That certification indicates that the manufacturer has met the requirements to produce a NIOSH approved respirator. It also indicates that the mask meets the required standards. To ensure that your NIOSH approved mask is an accurate match for your needs, it is important to look at the label.

Take the time to look at the labels for your N95 Niosh approved masks to ensure that the manufacturer meets the necessary requirements. You should be able to feel confident that you are wearing a NIOSH approved mask.

Are All N95 Masks NIOSH Approved?

The first thing you need to understand about N95 NIOSH-approved masks is that they are not NIOSH approved. That means that, while they may look like they are, they really aren’t.

NIH is the acronym for the National Institute for Occupational Safety and Health, which is an independent organization. But that’s not to say that every single N95 NIOSH-approved mask is certified by NIOSH. It’s not.

So how do you know that the mask you are buying is all N95 masks NIOSH approved? Simply put, you need to find out the certification number. Most masks are sold with a label that says “NAAMI.” If your mask does not have this label, then it’s not all N95 NIOSH approved.

Now let’s take a look at what N95 stands for. NIOSH stands for the National Institute for Occupational Safety and Health. It’s the foundation of all medical protection standards.

N95 is the final step in the certification process for NIOSH products. Basically, every company selling NIOSH-certified equipment will tell you that it is NIOSH-approved. That doesn’t mean that it actually is. The N95 certification process is so stringent that a product has to pass multiple tests in order to become certified.

Many people don’t even realize that the N95 rating on a certain pair of safety glasses or a certain type of respirator only gives a very rough indication of whether or not the product is NIOSH approved. You can have the best safety glass on the planet and still be rejected if it fails the final test, which is to test for particle particles. Even a pair of n95-rated glasses will not pass this test.

When you go to buy a pair of NIOSH-approved masks, you should make sure that they’re all approved by NIOSH. They should come with a label that reads “NAAMI.” Or, even better, ask for the certification number on the back of the mask and see if it’s there. You’ll know that you’ve found a pair of NIOSH-approved masks if the label is there, so take your time and double-check it.

If you get a NIOSH-approved mask and it does not come with a label saying “NAAMI,” return it and get a new one. This rule is in place for a good reason. People want to be sure that they are using a certified safety item.

Tags： n95 niosh-approved masks

N95 Niosh-Approved Masks are masks that have obtained the mandatory safety standards for respirators in the United States. This standard can only be passed by the EPA (a federal agency that has passed the N95 standard).

N95 Niosh-Approved Masks information introduction

N95 Niosh-Approved Masks said that under the testing conditions specified in the NIOSH standard, the filter material of the mask has a filtration efficiency of 95% for non-oily particles (such as dust, acid mist, paint mist, microorganisms, etc.).

The National Institute for Occupational Safety and Health (NIOSH) The National Institute of Occupational Safety and Health (NIOSH) is a federal agency dedicated to generating new knowledge in the field of occupational safety and health and converting that knowledge into practice to improve workers.

The N95 mask is one of the nine anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health). “N” means not suitable for oily particles (the fume produced by cooking is oily particles, and the droplets produced by people talking or coughing are not oily); “95” means the filtration efficiency under the test conditions specified by the NIOSH standard Reach 95%. N95 is not a specific product name. As long as the products meet the N95 standard and pass the NIOSH review, they can be called “N95 masks”.

According to the filtering characteristics of the middle filter of the mask, it is divided into the following three types:

N series: N stands for Not resistant to oil, which can be used to protect non-oily suspended particles.
R series: R stands for Resistant to oil, which can be used to protect non-oily and oily suspended particles.
P series: P stands for oil Proof, which can be used to protect non-oily and oily suspended particles.

According to the lowest filtration efficiency of the filter material, masks can be divided into the following three levels:

Level 95: indicates that the minimum filtration efficiency is 95%.
Level 99: indicates that the minimum filtration efficiency is 99%.
Level 100: Indicates that the minimum filtration efficiency is 99.97%.

The combination is N100, N99, N95, R100, R99, R95, P100, P99, P95. There are 9 kinds in total.

N95 Niosh-Approved Masks application process

For manufacturers who apply for N95 for the first time, the application is divided into two stages:

The first stage. Submit a questionnaire (given by NPPTL) and photos (appearance of the company’s factory, product production line, etc.) for NPPTL evaluation. After the NPPTL evaluation is qualified, the manufacturer will be given an enterprise code and other relevant information, and the first stage is over. It will take about 3 weeks to one month to complete the first stage from the submission of the information.

second stage. After the first stage is over and the documents sent by NPPTL are received, detailed application materials are prepared. In addition to filling out the standard form, the company also needs to provide the following materials that meet the standard requirements: Pre-test data, Drawings, Assembly Matrix, Draft approval labels,QA manual,Process Quality Control Plan,Service Life Plan,User’s Instructions,Test samples and Hardware.

Pay the inspection fee in advance when submitting the information. If the submitted materials are unqualified, NPPTL will request rectification and provide it again. Everything went well, starting from the submission of information, the second phase will take about 3-4 months.

The manufacturer obtains N95 Niosh-Approved Masks. NIOSH will conduct random checks on the certified products sold by the manufacturer on the market every year to determine whether the company always meets the requirements of N95.

N95 Niosh-Approved Masks application notes

N95 certificates will only be issued to entities that can control product design, and only manufacturers and designers (contracted by others) can apply. Importers or any distributors cannot be the beneficiaries of the N95 certificate, which means that the N95 certificate will not be issued to them, whether it is a secondary conversion or they reapply (for the manufacturer’s product).

N95 certification is charged according to the model. The more models, the more expensive the cost. The specific classification is determined by NPPTL evaluation. That is to say, if the manufacturer provides a series model when applying, there are several small models below, NPPTL may require the manufacturer The model is divided and refined.

KN95 mask can help reduce exposure to biological substances, like bacteria and viruses. Please note however that wearing a mask cannot eliminate the danger of infection because it depends on the right fit of the wearer. A study published in 2008 showed that masks were up to 80% effective in reducing transmission and infection from airborne virus.Different countries have different regulations and standards for facepiece respirators, and they are applicable to their respective national physical characteristics, national acceptance, etc.

But there are exceptions, during emergency situations such as COVID-19 Pandemic in 2020, health authorities may authorize the use of certain foreign standards of facepiece respirators such as N95, KN95, or FFP2 equivalent.

Standards of facepiece respirators in different countries:

United States NIOSH: N95/N99
Europe CE EN 149:2001+A1:2009: FFP2/FFP3
China GB2626-2006:KN95
Korea KMOEL – 2017-64: Special 1st

KN95 Face Masks

KN95 masks are regulated by the Chinese government under regulation GB2626-2006 and are rated to filter 95% of particles.

The FDA updated guidance in May 2020 restricts the use of certain KN95 masks as suitable NIOSH substitutes in medical institutions.

N95 Respirator Masks

N95 Respirator Masks, which filter up to 95% of particles and create an airtight seal around the face, most commonly available and well-known in the United States. They are regulated by the CDC and NIOSH.

N95 Respirator Masks regulated and approved by the FDA are those used for medical purposes.

The latest news, because of the COVID-19 pandemic, the FDA released guidance that certain NIOSH approved respirators not currently regulated by the FDA are cleared to be used in a healthcare setting by health care personnel during the emergency coronavirus outbreak.

FFP2 Respirator Masks

FFP2 respirator masks are certified by the European Union to meet the standards of CE regulation EN 149:2001+A1:2009 for filtering up to 94% of particles.

In response to the COVID-19 outbreak, on March 28th, 2020, the FDA announced that certified European CE EN-149 FFP2 respirator masks are cleared for emergency use under certain conditions when there is a shortage of NIOSH approved N95 respirators.

N95 Masks vs KN95 Masks vs FFP2 masks

N95 and KN95 masks both filter up to 95% of particles and create an airtight seal around the face.

Differences between N95 masks vs KN95 masks are that KN95 masks often use the earloop method of wearing the respirator whereas the N95 masks use two head-strap attachments, one that goes around the back of the head under the ears and another that goes on the top over the crown of the head above the ears. It really comes down to personal preference in terms of which one is more comfortable for the wearer as well as the level of safety and protection one feels is necessary given the particular activity being carried out.

The difference between N95 Masks, KN95 Masks, FFP2 masks

On May 7, 2020, the FDA updated its April guidelines to restrict the use of certain KN95 masks in medical institutions as suitable NIOSH substitutes, approval of emergency use of KN95 masks and FFP2 masks in the absence of NIOSH approved N95 masks.

What are the differences between Surgical face mask, KN95 face mask, and N95 face mask? Due to the occurrence of COVID-19, this issue has become a very concern for everyone.

1. What is the difference between the KN95 face mask, and the N95 face mask?

KN95 face mask: It is stipulated in Chinese norms and standards. According to Chinese norms and standards, masks can be divided into two categories: KN and KP. KN is suitable for filtering non-oily particles, and KP is suitable for filtering oily particles. The following figure is the percentage of filtration efficiency. KN95 face mask stipulates that the filtration efficiency for non-oily particles above 0.075 microns is greater than 95%.

N95 face mask: American NIOSH dust mask standard, non-oily particulate filtering efficiency ≥95%.

KN95 face mask and N95 face mask just have different names, and the masks produced according to these two standards have the same protection level. You can rest assured to buy any KN95 face mask or N95 face mask standard mask, there is no difference in protection effect.

2. Precautions for wearing the KN95 face mask and N95 face mask

1) Before wearing the KN95 face mask and N95 face mask, or during wearing a KN95 face mask and N95 face mask, avoid touching the inner side of the KN95 face mask and N95 face mask to reduce the contamination of KN95 face mask and N95 face mask may.

2) Distinguish the inside, outside, top, and bottom of the KN95 face mask and N95 face mask; the light color of the KN95 face mask and N95 face mask is inside; one end of metal strip/sponge strip is above KN95 face mask and N95 face mask.

3) Do not squeeze the KN95 face mask and an N95 face mask by hand. Including the KN95 face mask, you can only isolate the virus on the surface of the face mask. If you squeeze the face mask by hand, the virus will soak the face with the droplets. mask, there is still a chance of infection.

4) Make sure that the KN95 face mask and N95 face mask have good adhesion with the face. The simple test method is: after putting on the KN95 face mask and N95 face mask, exhale hard, and the air cannot leak out from the edges of the KN95 face mask and N95 face mask.

KN95 face mask and N95 face mask are not omnipotent, but wearing a KN95 face mask and N95 face mask correctly, often washing hands and disinfecting, can reduce the chance of infection!

No matter what kind of face mask, try not to bring it back, and do not reuse the face mask at the same time. It is also necessary to understand the correct way to wear the face mask. Only wear the face mask correctly to protect it!

3. Do KN95 face mask and N95 face mask need breathing valves?

KN95 face mask and N95 face mask are divided into two types with or without an exhalation valve. Whether there is an exhalation valve does not affect the respiratory protection of the wearer.

KN95 face mask and N95 face mask respirator may make the breathing of the wearer more difficult for people with chronic respiratory disease, heart disease or other diseases accompanied by symptoms of dyspnea, so use KN95 face mask equipped with an exhalation valve And N95 face mask can make them breathe easier and help reduce heat accumulation.

Simply put, the KN95 face mask and N95 face mask with exhalation valve can protect the wearer, but not the people around them.

If you are a virus carrier, please choose the KN95 face mask and N95 face mask without exhalation valve, do not spread the virus.

If you want to maintain a sterile environment, you can not use a KN95 face mask and N95 face mask with an exhalation valve, because the wearer may exhale bacteria or viruses.

4. How long can KN95 face mask and N95 face mask be used?

At present, the WHO has not made a clear conclusion about the best wearing time of the KN95 face mask and N95 face mask.

Some researchers have done research on the protection efficiency and wearing time of KN95 face mask and N95 face mask: the wearing efficiency of KN95 face mask and N95 face mask is 2 days, the filtration efficiency remains above 95%, and the respiratory resistance does not change much; wearing it for 3 days The filtration efficiency is reduced to 94.7%.

The recommendation given by the US CDC is that in the absence of a sufficient supply of face masks, as long as the device is not obviously stained or damaged (such as creases or tears), it can be considered for reuse.

Special circumstances require timely replacement:

1) Breathing is difficult.
2) The face mask is damaged.
3) The face mask is contaminated.
4) There is odor in the face mask.
5) The face mask can no longer fit the face.

tips: Under the COVID-19, it is necessary to actively cooperate with wearing the KN95 face mask and N95 face mask.

Under the COVID-19, it is necessary to actively cooperate with wearing the KN95 face mask and N95 face mask. But do you know how to tell whether the KN95 face mask / N95 face mask is true or not?

1. Authentication and function of KN95 face mask / N95 face mask

KN95 face mask / N95 face mask are anti-particulate masks. The general name of anti-particulate mask products is 3M masks (3M is both the company’s name: Minnesota Mining Manufacturing Company and a registered trademark).

1. N95 face mask is one of 9 anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health).

“N” means not suitable for oily particles (oil fumes produced by cooking are oily particles, and the droplets generated by people talking or coughing are not oily), so it can not be used to block oil fumes, but it can effectively prevent droplets, Viruses, and particles;
“95” means that the filtration efficiency reaches 95% under the detection conditions specified in the standard.

The KN95 face mask is in compliance with China’s mandatory GB 2626 standard.

2. N95 is not a specific product name. Rather, as long as it meets the N95 standard and has passed the NIOSH review, it can be called the “N95 face mask.”

2. How to distinguish the true and false of the KN95 face mask / N95 face mask?

1. No odor: First of all, the KN95 face mask / N95 face mask is a face mask with a relatively high protection level. It must be tasteless. Only the activated carbon mask has a slight fragrance of activated carbon, and the rubber band has no taste. If it is a bit smelly, it must be a fake or fake face mask.

2. Printed handwriting on face mask: Because KN95 face mask / N95 face mask is laser printed, the printed fonts have traces of laser corrosion, fake and shoddy products will not have this. In addition, the authentic KN95 mask will have KN95 on the outer surface, which is clearly visible.

3. Face mask packaging: If the font on the face mask packaging does not have light transmittance or the printing color has a color difference, it is definitely a fake and shoddy product. Is there the word GB2626-200 on the KN95 mask or packaging, which is the standard required by the country.

4. Quality of face mask: The regular KN95 face mask / N95 face mask will have deep impressions, and fake and inferior products will not have such deep impressions.

5. Medical information website query: You can go to the medical information website to check according to the detailed information or number information of the KN95 face mask / N95 face mask. It is true that there are remarks on the website for product information.

6. Inside the KN95 face mask / N95 face mask: There is really nothing printed inside the KN95 face mask / N95 face mask. At the same time, the breathing port is deep, and there will be a comfortable cotton pad at the nose.

7. Nose pads of KN95 face mask / N95 face mask: The genuine nose pads of KN95 face mask / N95 face mask are relatively thick and will not be deformed after being pressed down.

8. KN95 face mask / N95 face mask lock edge: The lock edges around the genuine KN95 face mask / N95 face mask are clearly visible, the depth is also deeper, and the lock edges around the fake are not clear.

9. KN95 face mask / N95 face mask straps: Genuine KN95 face mask / N95 face mask straps are pressed, not sewed, and will be tighter after being put on for the first time.

The above are 9 methods for distinguishing true and false by KN95 face mask / N95 face mask. If you want to know more about the KN95 face mask / N95 face mask, you can follow us.

N95 face mask have so many models, would you pick them? Can the mask have a breathing valve? 3M N95 face mask model inventory.

What are N95, R95, and P95  face masks? What are the differences? How often do N95 face masks need to be replaced? Today I will do homework for 3M N95 face masks for you. Check out the differences between the functions of each model of 3M N95 face masks, and how to choose the one that suits you from each model of 3M N95 face masks.

1. What is the N95 face mask?

N95 face masks comply with NIOSH (National Institute of Occupational Safety and Health) standards and can filter 95% of non-oily particles with a diameter of 0.3 microns or more in the air. As long as they meet the N95 standard and pass the NIOSH review, the particulate filter mask respirator can be called the N95 face mask.

N95 face masks in the United States are mainly industrial protective masks, which are dust masks that meet NIOSH standards. For some dusty working environments, N95 face masks can prevent the inhalation of harmful airborne particles. N95 face masks are also good for mountain fire smoke pollution. Protective effect. If you want to do carpentry and mix cement at home, you may also consider wearing N95 face masks protection.

2. What are the differences between N95, R95, and P95 face masks?

N95 is one of NIOSH’s ratings for the protection standards of particulate filter mask respirators. “N” means Not resistant to oil, and “95” means that the filtration efficiency is 95% or more. In addition to 95, there are grades of N99 (filtration efficiency not less than 99%) and N100 (filtration efficiency not less than 99.97%).

“R” means Somewhat resistant to oil, “P” means Strongly resistant to oil/Oil-proof. Both R95 face masks and P95 face masks can filter 95% of non-oily particles and oily particles with a diameter of 0.3 microns or more in the air. The service life of R95 face masks is up to 8 hours, and the service life of P95 face masks can be up to 40 hours or 30 days. R series and P series masks also have R99/R100 and P99/P100 classification.

N95 is the standard of the United States. Other countries and regions in the world also have the same type of mask, but the name is different. For example, it is also called the KN95 face mask in China.

As can be seen from the above, N95 is actually the lowest standard among the 9 classifications formulated by NIOSH for the protection standards of dust masks.

3. What is the difference between N95 face masks and medical face masks?

Medical-surgical masks can isolate large particles such as droplets, and the outer layer is a waterproof layer that can block liquid splashes. However, surgical masks cannot effectively filter the fine particles in the air, and the design of surgical masks is not sealed, and it cannot completely prevent air from entering the gaps on the edges of the mask.

N95 face masks are particulate protective masks that can filter tiny particles with a diameter of more than 0.3 microns, but each time you wear an N95 face mask, you must test the tightness of the edges of the mask to ensure that there is no air leakage to have a real protective effect.

Industrial N95 face masks are mainly used when the air quality is not good. It can prevent or reduce the dust, pollen, and germs in the air from entering the human respiratory organs, such as preventing smog and PM2.5. N95 face masks can also filter bacteria and viruses with a diameter of 0.3 microns or more, so whenever a large epidemic infectious disease spreads, N95 face masks are also a popular choice for everyone.

But in fact, for the prevention of bacterial infections in the air such as influenza or Wuhan pneumonia, ordinary people choose medical surgical masks to be more cost-effective. First of all, N95 face masks can only block 95% of the particles, and wearing N95 face masks must also follow strict procedures. If they are used incorrectly, the protective effect will be greatly reduced. According to a study published in 2008 by the International Journal of Infectious Diseases, the correct use of masks can effectively reduce the spread of influenza virus infection. However, the use of P2 masks without gas density testing is not significantly different from the use of medical surgical masks.

And another study data shows that wearing only a mask has no preventive effect, but the combination of wearing a mask and washing hands frequently can reduce the chance of getting an influenza disease by 75%. Therefore, to prevent infection, the most important thing is to wash your hands frequently!

4. Is there any difference between different styles of N95 face masks?

N95 face masks have many different colors, shapes, and styles to choose from. Some shapes and styles can better fit some people’s facial shapes and will be more suitable for individuals.

According to CDC, as long as it is a product approved by NIOSH, used in an environment that meets the requirements of OSHA regulations, and the user wears a mask to test to ensure the gas density, then no matter what color, shape or style of N95 face mask, can achieve the same expectations The protective effect, that is, “the filtration efficiency of non-oily particles with a diameter greater than 0.3 microns in the air reaches more than 95%”.

5. How long can N95 face masks be worn?

According to the instructions on the 3M official website, the service life of N95face  masks does not have a clear time limit, just saying “When the mask is dirty, damaged, or you feel difficulty breathing, you must leave the contaminated area and replace with a new mask.”

According to CDC instructions, practical experience shows that N95 face masks can be used continuously or intermittently within 8 hours to maintain the effect. Whether they can be used for a long time depends on whether the N95 face masks are dirty, whether they can continue to seal, and whether they affect smooth breathing; repeated use of N95 face masks is required Pay attention to the problem of cross-contamination, and because the circumstances are different, the maximum number of safe reuse of N95 face masks cannot be determined.

The CDC also stated that using N95 face masks for an extended period of time is better than taking them off and putting them on again, which can reduce the possibility of contamination. Especially in an environment where there are epidemic bacteria in the air, if the mask is removed, it is difficult to ensure that the bacteria will not adhere to the inside of the mask.

6. 3M N95 face mask selection guide

3M is a world-renowned American manufacturing company, formerly known as the Minnesota Mining and Manufacturing Company. It produces a lot of high-quality industrial products, as well as medical supplies and household products. I believe that every small partner has used several 3M products. The N95 face masks produced by 3M Company have NIOSH certification and have different styles and sizes.

Most protective masks will be clearly marked on the outside of the mask, which can be used to identify the model of the export mask, NIOSH certification, and other information.

1) N95-8210

The most common N95 face mask model on the market can filter at least 95% of solid or liquid non-oily particles with a diameter of 0.3 microns or more. The use of advanced electrostatic media technology can enhance the particle capture ability, while reducing breathing resistance, allowing the wearer to breathe more smoothly; the elastic band is welded to make it more durable, and the foam nose pad design makes it more comfortable to wear.

There is also an economical version of N95-8200 with equivalent functions; N95-8210plus, which uses a braided headband that is not easy to pull the hair to make wearing more comfortable; and the same product N95-8110S, which is more suitable for people with small faces.

2) N95-8210V

On the basis of 8210, a 3M Cool Flow breathing valve is added to make breathing (exhalation) easier, keep the face cool and reduce the accumulation of moisture inside the mask. N95 face masks with breathing valves are more comfortable to use in hot and humid environments and are also suitable for situations where masks need to be worn for a long time.

The principle of the one-way breathing valve is that the valve will be opened a little when exhaling to make the air easier to discharge, but when not breathing or inhaling, the valve will automatically seal tightly to maintain the protective effect. As for whether or not to worry about germs entering the open valve when the airflow is exchanged, it is a matter of opinion.

The more interesting CDC FAQ on N95 face masks, about whether medical institutions can use N95 face masks with breathing valves. The CDC believes that N95 face masks can be used when it is not necessary to maintain a sterile environment; however, the breathing valve allows unfiltered air to flow out, which will pollute the sterile environment, so it should not be used in sterile environments such as operating rooms for invasive surgery.

3) N95-8511

The most popular N95 face mask with a breathing valve on the market. The breathing valve can keep the inside of the mask cool. It is more suitable for hot and humid environments or when it needs to be worn for a long time. The braided headband and M-shaped nose clip improve comfort.

In addition, the overlay cushion design is added on the basis of 8511, and the soft inner layer provides an N95-8211 face mask for extra comfort.

4) N95-9210+ / 9211+

The Aura series N95 face masks adopt a folding three-sided three-dimensional structure design to reduce the problem of fogging of the glasses. The chin design is more convenient to wear face masks, positioning, and adjustment. It has an innovative breakthrough in portability and comfort. The 9210+ N95 face mask does not have a breathing valve, and the 9211+ version has a breathing valve.

5) N95-9105 / 9105S

The flex series is an economical version of the portable N95 face mask. The proprietary V-shaped fold design makes breathing easier and can bend with the movement of the mouth. It is more convenient to wear a mask to speak. There are two size options.

6) N95 face mask suitable for welding and metal casting

8. Medical N95 face mask

Medical N95 face masks are more waterproof than other industrial N95 face masks. They are protective against the splashing and splashing of blood and other infectious liquids. They can block some airborne biological particles, which is in line with the CDC’s tuberculosis control guidelines. FDA approved as a surgical mask.

For the protection of bacterial germs, the protective effect of medical N95 face masks should be the best. However, it is not necessary for ordinary people to choose this type. It also has a certain blocking effect for a small amount of N95 industrial spray, and generally, everyone will not encounter a large amount of liquid splashing; it is likely to be caused by the use of electric medical equipment when performing surgery with a doctor Large particles and liquid splashes are different.

N95-1860: The most popular medical N95 face mask, traditional cup design.
