What is KN95 Particulate Respirator?
The KN95 particulate respirator (face masks) is Chinese standards and can filter 95% of non-oily particles with a diameter of 0.3 micrometers or more in the air. As long as the particle filter respirator meets the KN95 standard and passes the review, it can be called a KN95 mask. So KN95 only refer to a type of particulate respirator and similar to American N95 (NIOSH N95).
Here are stack up of our KN95 Particulate Respirator. We had two layers of Melt-bown (filter layers) which is major and most important material of respirator, because the filter efficiency. But some mask only had one layer of Melt-bown.
Outer layer: Non-woven fabric
Middle layer 1: Melt-Bown (Filter layer) ，
Middle layer 2: Melt-Bown (Filter layer)
Inner layer: Non-woven fabric
1. No glass fibers, hypoallergenic
2. Nose bar adaptable
3. Designed to fit tightly: have a seal around the wearer’s face which helps prevent air from leaking into the respirator, thus protecting the worker from particular hazards
4. Elastic ear loop is easy to wear and no pressure to the ears.
5. Non-irritating, soft and comfortable.
6. Good lamination between each layer, no separation between layers, so you can have better protection for particulate.
7. Testing according to GB2626-2006 (Chinese standard)
1. Normal KN95 is not suitable for hospital, because there’s no requirement for KN95 to have the function of Synthetic blood penetration.
2. If you need medical KN95, then the testing method should following up Chinese Standard: GB19083-2010 which is for medical purpose.
3. It is highly recommended to change disposable face masks every eight hours.
4. Please allow 1-5mm differences due to manual measurement

A) When should I get a new respirator?
When determining whether I need new respirators, remember the three D’s:
• Difficult to breathe through
Dirty respirators – A respirator cannot have dirt or debris where it contacts with the face. Dirt and debris not only affect the performance of the respirator, they also can expose the user directly to contaminants, particularly if the debris is contaminated or otherwise toxic.
Damaged respirators – If a strap or nose clip is broken then the product cannot properly seal on the face and cannot be used. It sounds simple, but we have seen respirators that looked like they were 10 years old. If your mask has an exhalation valve, make sure that it is free of debris and not damaged.
Difficult to breathe through – When a facepiece becomes difficult to breathe through or a worker feels a change in the resistance to take a breath, the respirator needs to be changed or throw out.
B) Testing and Checking Respirator before using.
However, each time you wear a KN95 respirator (mask), you must test the seal of the edge of the mask (Fit Test) to ensure that there is no leak Real protective effect. Therefore, KN95 masks are not suitable for people with hair on their faces and children, because these people cannot guarantee the tightness of wearing KN95 masks.
In addition, people with chronic respiratory disease, heart disease, or other people with breathing difficulties should consult their doctor before using KN95 masks, because KN95 masks will make it harder for the wearer to breathe.
Industrial N95 masks are mainly used when the air quality is not good, which can prevent or reduce the dust, pollen and germs in the air from entering the human respiratory organs, such as preventing haze and PM2.5. KN95 masks can also filter aerosols carrying bacterial viruses with a diameter of 0.3 micrometers or more, so whenever a large epidemic spreads, KN95 masks are also a popular choice for everyone's epidemic masks.
C) How soon you can ship out my order?
The normal lead time is 1-2 days if what you order is 50-500 pcs, as we always has some small quantity stock. And it’ll be 3-5 days if you order > 1,000 pcs.
D) How fast the shipment can be?
We will ship it from China and it’ll take about 7 calendar days ship to most countries on the Earth, if customs clearance is successfully and smoothly and sometimes only 3-5 days, but maybe also taking 10 days if customs hold the shipment. Please make sure there’re delivery service in your area. We will normally use DHL, FedEx.
Please let’s know if you have any questions about KN95 Particulate respirator (KN95 face mask).
With regard to the choice of epidemic masks:
If the germs are mainly transmitted through large droplets (for example, the patient sprays droplets from sneezing or coughing on other people), it is more appropriate to wear ordinary waterproof surgical masks for protection.
If the particles of germs or harmful substances are relatively small and can be suspended in the air for a long time, a large number of them can be transmitted through the air, then the protective effect of wearing industrial N95 masks will be better. N95 masks are CDC approved tuberculosis, SARS and other airborne Minimum protective masks for diseases;
Medical / surgical KN95 masks also meet the N95 standard in terms of particle filtering effect, but it can also be waterproof and prevent blood, body fluids and other liquids from penetrating into the mask. The FDA approved it as a surgical mask.
For the prevention of droplet-borne diseases such as influenza virus, ordinary people choose medical masks to be more cost-effective. New Coronavirus (2019 Novel Coronavirus) can also be transmitted through droplets and contact, similar to the way influenza viruses are transmitted .
First of all, the KN95 mask itself can only block 95% of the particles (not 100% defense). When wearing the KN95 mask, you must also follow strict procedures. If you use it incorrectly, the protective effect will be greatly reduced. A study published in the International Journal of Infectious Diseases in 2008 showed that the correct use of masks can effectively reduce the spread of influenza virus infection, but the use of P2 masks (equivalent to N95) without gas density testing and the use of medical surgical masks have no obvious effect difference.
And another study data shows that wearing a mask alone has no effect on preventing influenza, but the combination of wearing a mask and washing your hands frequently can reduce the chance of contracting influenza by 75%. Therefore, to prevent infection, the most important thing is to wash your hands frequently!
How long can I wear the KN95 mask?
According to the CDC, practical experience shows that KN95 masks can be used continuously or intermittently for 8 hours to maintain the effect. Whether they can be used for a long time depends on whether the KN95 mask is dirty, whether it can continue to be sealed, and whether it affects breathing. The KN95 mask needs to be reused. Pay attention to the problem of cross-contamination, and because the situation is different, the maximum number of safe re-use of KN95 masks cannot be determined.
The CDC also states that prolonged use of KN95 masks is better than taking them off and putting them on again, reducing the possibility of contamination. Especially in an environment where there is an epidemic germ in the air, if the mask is removed, it is difficult to ensure that the germs do not stick to the inside of the mask.
What to do after using KN95 mask?
The KN95 masks that you buy are basically disposable N95 masks, and they should be discarded directly into the covered garbage bin after use. The US-approved reusable N95 masks / Reusable Respirators are actually gas mask styles, and they can be used freely with filter mats, as long as the filter mats are replaced regularly.
