KN95 MASK & N95 FACE MASK FAQs
KN95 masks since April 2020 have become available through the Chinese Government to help fight the COVID-19 pandemic. Regulations GB2626-2006, GB262-2019, and GB19083-2010 govern their production.
Healthcare workers use the KN95 respirators since they meet the FDA guidelines and international standards in the US. The KN95 respirator features a tight face fit and thus create an airtight seal. What is unique about the KN95 is the fact that it uses an ear loop fastener, to distinguish it from other types of masks with head straps. Many favor the KN95 mask design due to how easy to put on. Its design also fits very well from the nose to the chin area preventing particles from bypassing the masks’ filter.
The KN95 masks provide 95% protection against particles greater than 0.3 m in diameter. Therefore not only will it stop fine particles such as dust and pollen, it also will reduce the risk of viral infections.
Typically Kn95 masks have 5 layers of protection. The fabrics commonly used is hot air cotton, melt-blown nonwoven material. The nonwoven material is hydrophobic, & is water & droplet-proof. Moreover, the hot air cotton is soft and ensures lower air velocity.
Further layers facilitate particle filtration and being hypoallergenic materials, are skin-friendly. Such a layered fabric design contributes to the mask’s particle filtering efficiency and generally superior design. Further enhancing the KN95 design is foldable and features a bendable nose bridge to ensure an air-tight fit.
The WHO has given guidance and available evidence when it comes to using respiratory masks like the KN95 as a protective measure against COVID-19. So far, it appears that these measures should be effective to prevent virus transmission and for protection against infection.. These masks are being used in Angelino Heights by health care providers. And since the consensus is they protect us from at least 95% of all particles, bacteria, and viruses, their use will be continued. However, the WHO maintains and emphasizes that there are not enough evidence to determine conclusively the effectiveness of respiratory masks like the KN95 or N95 against the Corona virus in particular. Nevertheless they still advise that respiratory masks be used as a preventative measure against COVID-19.
Even though the KN95 & N95 masks are designed for a one time use, in light of COVID-19 Crisis and the shortage of PPE supplies, the CDC recommends reuse. Methods for extended mask use can be found at The National Institute for Occupational Safety and Health (NIOSH).
NIOSH indicates that N95 & KN95 masks may be reused if stored properly & if only used by one person. Someone may use a respiratory mask for an extended period for one day after which the mask should not be used.
KN95 masks have a filter efficiency of 95%+ making them as good as N95 masks and better than PM 2.5 filter masks (60%) & surgical masks (95%) Generally, these masks are very effective against airborne particles, viruses, and bacteria. Their effectiveness was tested and proven through international regulations and regulatory standards of FDA, CDC, etc.
Mask filter efficiency according to studies however do show a drop in filter efficiency after sterilization or extended use. Mask efficiency can drop over 50%. This is simply because masks have been designed for one time use and should then be disposed of. Their extended use and reuse requires discretion and they can only be reused if stored properly and if it maintains its fit and function.
According to the CDC (Center of Disease Control), decontamination recommendations in regards to handling a decontaminated mask are as follows:
- Before and after touching and adjusting a respiratory mask, you should clean your hands with soap and water, or an alcohol-based sanitizer with at least 60% alcohol.
- Avoid touching one’s mask.
- When touching and adjusting your mask, make sure to use a pair of clean (non-sterile) gloves.
- Ensure one’s mask stucture and/or fit has not been compromised in any way.
- Look at the mask components, the straps, the nose bridge, the material to see if mask fit, efficiency or structure has been compromised.
- Always make sure to discard a used face mask properly and never leave it exposed, where other people can touch it or reuse it.
Not every brand of KN95 mask is created equal and because of the high demand for certified masks it is quite likely some are counterfeit. How can one tell?
- Claims the mask has regulatory approval for children (NIOSH does NOT condone respiratory protection for children).
- Attached to the face mask are decorative attachments or fabrics.
- There is an FDA logo on the box or packaging of the mask; FDA does NOT approve the use of their administration label on any respirator packaging,
- KN95 Masks don’t have NIOSK logos or a TC number on them, only US market N95 do.
- No markings on the face mask whatsoever.
- Instead of ear loops the KN95 mask has straps. There are no straps on a KN95 mask.
If you wish to ensure your respirator is genuine you can do these additional tests:
Flammability: A certified KN95 mask will melt but not ignite. Counterfeit KN95 masks which are made from cheap materials will ignite when in contact with a flame.
Permeability: The ability to limit airflow, you can test by using a lighter or candle. See if you can blow out the flame by blowing through the mask. With a certified mask this will be not possible.
Liquid resistance: If a mask is KN95 certified, it will have a waterproof layer that will prevent fluid to pass through. You can test this by pouring water into the mask. A certified KN95 mask will contain all the water without leaking, while a counterfeit mask will allow water through.
For a proper mask fit do the following:
- Wash your hands thoroughly with soap and water or an alcohol-based sanitizer before wearing your mask.
- Holding the inside of the respirator mask face up, place the mask under the chin.
- Holding the ear loops, stretch it each ear.
- Position and adjust the mask on your nose by using both of your hands. Mold the nosepiece to the shape of your nose by pushing downwards on each side of the nosepiece.
- To ensure a good fit, your face-mask must seal properly. With both hands on the mask, exhale. Readjust the fit if air leaks, especially around the nose piece.
“The KN95 is practically equivalent to a N95 in every aspect,” says Amin. “Customers seem to believe that the N95 is superior at blocking airborne particles, but the KN95 is just as good, if not better,” he insists. “Many N95 masks are also made in parts of China and Asia so the notion that all N95 are U.S. created is inaccurate as well.” The FDA has released a list of approved N95 masks here Source: https://www.rollingstone.com/product-recommendations/lifestyle/n95-vs-kn95-masks-1044184/ See also https://ppe4wholesale.com/kn95-3ply-masks/ for wholesale purchases of our 3 Ply Surgical Mask and KN95 product line as well as the CDC [Center for Disease Control] KN95 test results for our KN95 manufacturer.
