KN95 MASK & N95 FACE MASK Frequently asked questions
KN95 masks since April 2020 have become available from the Chinese Government to help fight the COVID-19 pandemic. Regulations GB2626-2006, GB262-2019, and GB19083-2010 govern their production.
Healthcare workers extensively use the KN95 face masks since they meet the FDA guidelines and international standards in the US. The KN95 mask features a tight fit to the face to 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 stopping airborn particulates from bypassing the masks’ filter.
The KN95 mask design provide 95% protection against particles greater than 0.3 m in diameter. This means it is an effective barrier against bacteria, viruses, pollution particles, fine particles, dust, smog, pollen, reducing the risk of viral and bacteria infections
KN95 face masks are multi-layer masks, that usually feature 5-layer protection. Layers are typically high-quality, hot air cotton, melt-blown nonwoven fabric. The nonwoven fabric is hydrophobic, and is water and droplet-proof. In addition, the hot air cotton is soft ensuring slower air velocity.
Deeper layers facilitate particle filtration and being hypoallergenic materials, are skin-friendly. Such a layered fabric construction contributes to the mask’s efficient particle filtering and generally better design. Further enhancing the KN95 design is foldable and features a bendable nose bridge ensuring an air-tight fit.
The WHO has given guidance and available evidence when it comes to the use of face masks like the KN95 face mask as protection against COVID-19. So far, what they know is that these masks should be effective to prevent virus transmission and infection.. Health Care Professionals in Little Tokyo are using KN95 respiratory masks. The consensus is that these masks are 95% effective against particles, bacteria and viruses. However the World Health Organization indicates that not enough studies have been done to conclude conclusively that masks are effective against the CORON-19 virus. However, they advise that these masks should be worn as a part of the protective measure strategy in regards to infection transmission and the prevention of virus transmission among health care workers, patients and the general public.
Both the N95 and KN95 masks are intended for to be used only once. This means that each new use would normally require a new mask. However, since there is a shortage of the N95 and KN95 masks, the CDC has recommended reusing disposable masks since we are in a crisis situation.Strategies for extending mask use for the N95 or KN95 are available at The National Institute for Occupational Safety and Health (NIOSH).
According to NIOSH, the respiratory face masks can be reused only if properly stored between uses and only if used by the same person, and used for an extended period of time. Thus one may wear the same mask for a continuous period of time in one day, after which the mask should be not be used due to repeated exposure and close contact.
KN95 masks have at least 95% filtration efficiency. Thus they are as good as the N95 and better than surgical masks (95% filtration efficiency) and PM 2.5 filter masks (having 60% +/- efficiency). Generally, these masks are very effective against airborne viruses, bacteria and particulates. Their efficiency was tested and proven through international regulations and regulatory standards of FDA, CDC, etc.
Studies however show that filter mask efficiency drops considerably after sterilization or extended use. 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.
Follow these recommendations by the Center of Disease Control (CDC) for handling a decontaminated mask:
- Wash your hands with a 60% alcohol-based sanitizer or soap and water before and after touching and adjusting the respiratory mask.
- Avoid touching one’s mask.
- Wear a pair of clean non-sterile gloves when touching or adjusting the face-mask.
- Look at the respiratory mask to ensure whether its composition and fitting have been compromised.
- Check to ensure whether the mask components like the nose bridge, straps, and nose foam material did not degrade (which can compromise the mask efficiency, fit, and seal).
- Always ensure you don’t leave a used face mask where anyone can touch and use.
Not every brand of KN95 mask is the same and because of the high demand for certified masks it is quite likely some are counterfeit. How can one tell?
- Claims that the mask is approved for children (NIOSH does NOT approve respiratory protection for children).
- The face-mask has decorative fabric or decorative attachments, e.g. sequins.
- A FDA logo is printed the box or packaging; FDA does NOT approve their name on any packaging,
- KN95 Masks don’t have a TC number or NIOSK logos on them, only American-market N95s do.
- The filtering face piece respirator mask has no markings on it at all.
- There are straps instead of ear loops on the KN95. No KN95 has straps.
Here are some further things you can do to determine if a KN95 respirator is genuine:
Flammability: A certified KN95 mask will melt but not ignite. Counterfeit KN95 masks made from cheap materials will ignite when in contact with a flame.
Permeability: A certified KN95 face mask should limit the airflow going in and out of the mask. Test this by trying to blow out a candle or a flame of a lighter by blowing through the mask. With a certified KN95 face mask, you shouldn’t be able to blow out the flame no matter how hard one blows.
Liquid Resistance: A genuine KN95 mask has a layer in it that will prevent fluid from passing through. To check this, simply pour water into the mask, a genuine KN95 will not leak any water.
To properly put on a face mask follow these steps:
- First make sure you wash one’s hands completely using an alcohol based sanitizer or soap and water.
- Hold the earloop mask and nosepiece facing up, then place your mask under your chin.
- Place the earloops around each ear.
- Using your hands place and adjust the mask on your nose. You should mold the nosepiece to the shape of your nose by pushing downwards on both sides of the nosepiece.
- Always do a fit and seal check, first by putting both hands over the face mask. Make sure not to move or displace the position of the mask. You can test whether the mask fits properly by exhaling; if air leaks, then adjust the mask again, especially 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.
