A KN95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. The 'KN95' designation means that when subjected to careful testing, the respirator blocks at least 95% of tiny (0.3 microns) test particles. If properly fitted, the filtration capabilities of KN95 respirators exceed those of face masks.
KN95 Face Masks (Respirators) are CDC certified. The five layers foldable mask has 95% filtration efficiency and a suitable alternative to NIOSH N95. To comply with a particular standard, they must meet or exceed required physical properties & performance characteristics, which can vary according to the regulatory bodies of different countries. It is reasonable to consider China KN95, AS/NZ P2, Korea 1st Class, and Japan DS FFRs as "equivalent" to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g., viruses) - https://www.fda.gov/medical-devices/personal-protective-equipment-infection-control/faqs-shortages-surgical-masks-and-gowns. Ideal for daily use helping prevent the spread of germs and protect yourself from airborne particles, pollen, and other allergens.

How to Wear a KN95 Mask?
Perform hand hygiene before putting on a mask. Hold ear loop mask and nosepiece up.
Position the mask under your chin with the nosepiece up.
Pull the ear loop to each ear, hang it on until comfortable, position the mask low on your nose.
Using both hands, mold the nosepiece to the shape of your nose by pushing downward and outward, while moving your fingertips down both sides of the nosepiece.
Perform a fit check by pacing both hands completely over the mask. Be careful not to disturb the position, and exhale sharply. If air leaks, adjust the nosepiece as described in step 3 and 4.
Frequently Asked Questions
Regulated by the Chinese government, a KN95 respirator mask is a type of Filtering Facepiece Respirator (FFR). Like USA N95, KN95 has a minimum of 95% filtration and a maximum of 8% leakage to the inside. It is made to the GB2626-2006 standard.
Mainly used in construction, agriculture, and by healthcare professionals against airborne particles, infectious agents, and viruses, KN95s prevent the wearer from inhaling aerosols (dust, smoke, mist) as well as vapors or gases (disinfectants, anesthetic gases, droplets) that are health hazards. KN95s are currently used for protection against the coronavirus.
If your little one is under 2, the answer is no. WHO and UNICEF advise that children aged 12 and over should wear a mask under the same conditions as adults, in particular when they cannot guarantee at least a 1-meter distance from others and there is widespread transmission in the area.
N95, KN95 & other FFPs are all respirator masks that are subject to various regulatory standards around the world. Respirators certified to these standards are expected to have similar performance. There are slight differences in their specifications, like a variation in the maximum pressure the masks must be able to withstand as a person inhales and exhales. Here are the global standards by country:
- N95 (United States NIOSH-42CFR84)
- FFP2 (Europe EN 149-2001)
- KN95 (China GB2626-2006)
- P2 (Australia/New Zealand AS/NZA 1716:2012)
- Korea 1st class (Korea KMOEL – 2017-64)
- DS (Japan JMHLW-Notification 214, 2018)
Filtering facepiece respirators are subject to various regulatory standards around the world. N95 respirators are regulated by the United States National Institute for Occupational Safety and Health (NIOSH). KN95 respirators are regulated by the Government of China. Because there is a shortage of NIOSH approved N95 masks in the United States, if you do not have access to N95 respirators, then you can consider using a KN95 mask as an alternative. The KN95 Masks are foldable and flat packed whereas the N95 Masks are not.
Although KN95 respirators are designed for just one use before disposal, heating could be the best way to disinfect KN95 masks for reuse.
The CDC does have some guidance for healthcare workers who need to wear disposable masks for a long time or reuse them, which isn’t common in non-emergency situations.
No, you can’t wash KN95 masks because the filtering material of KN95 masks gets destroyed by the contact with water. Better, you can hang the mask in the sunlight for a few hours or just not wear it for 3 days.
Make sure to purchase any Personal Protective Equipment from a reliable supplier who has experience supplying certified and compliant parts. A reputable supplier will be able to provide you with authentic CE certifications and should be able to show you how to check that the manufacturer is registered. Upon request, a supplier should provide you with a certificate of conformance stating the product has been reviewed and conforms to the KN95 GB2626-206 standard.
KN95 masks have a wide price range based on quantity, availability, and level of certification available. Today, demand far outweighs the current supply of FFPs. Beyond the economics of supply & demand, the factors that go into the price of a KN95 include material costs, labor, transportation, duties & tariffs. China is the leading manufacturer of Personal Protective Equipment, and since the Covid-19 outbreak, flights from China to the US are limited, inflating the freight costs. Also, the particular nonwoven filtering fabric used in KN95s has become an in-demand commodity. All of these factors have led to increased costs. Over time, as supply meets demands, and flights fly more frequently, we expect prices to decrease.
The WHO guidelines recommend that every individual should wear a mask to protect them from viruses, bacteria, pollen, other particles as the KN95 mask has a filtration efficiency. However, the KN95 mask is going out of stock at the retail stores. So, people are moving towards online stores.

Before buying a KN95 mask, make sure you go through the given checklist which is used for the inspection of a standard surgical mask.
- Refer to the manufacturer’s name which is printed on the packaging.
- Have a look at the materials used in its manufacturing to ensure it is free from any component you are allergic to.
- Check the expiry date given on its packaging as the unused masks have the shelf life of three years from the date of manufacture.
- Verify the filtration efficiency of the mask. The masks must have a filtration efficiency of about 95% or more.
The face masks have become the need of the hour during this pandemic. All of us need to wear masks if we wish to return to work and socializing. This is the new normal. Many experts have said that the use of face masks have helped in flattening the curve and limiting the spread of COVID-19 in many countries.
So, make sure to get the certified KN95 masks for yourself and your family and stay safe from the asymptomatic carriers of the Coronavirus.
The respirator must form a seal with the wearer’s face, so that air passes through the filter (instead of around the edges) before it is inhaled. To ensure a proper seal, the wearer should ensure the respirator edges do not touch any facial hair. Clean-shaven is ideal for a good seal.
As per the WHO guidelines for COVID-19, KN95 masks can be used for 6-7 hours. If you use them for prolonged periods, the filtering material of KN95 masks loses its effectiveness.
The KN95 masks have an elastic that wraps around the head. Once they get stretched out too often, or too many times, the elastic becomes too loose.
Yes, KN95 may be used in the hospital setting. However, hospitals should prioritize using N95 respirators for aerosol generating procedures, including intubations, CPR or nebulizer treatments.
To help address concerns about availability during the COVID-19 pandemic, the FDA has issued Emergency Use Authorizations (EUAs) for certain PPE products including face shields, other barriers, and respiratory protective devices such as respirators (masks).
On August 5, 2020, the FDA issued an umbrella emergency use authorization (EUA) for certain disposable, single-use surgical masks in response to concerns relating to insufficient supply and availability of such masks. This EUA authorizes the emergency use of surgical masks that meet certain performance requirements for use in healthcare settings by health care personnel as personal protective equipment to provide a physical barrier to fluids and particulate materials to prevent HCP exposure to respiratory droplets and large particles during surgical mask shortages resulting from the COVID-19 pandemic. Surgical masks that have been confirmed by FDA to meet the criteria under the EUA are included below in Appendix A as authorized surgical masks.
