KN95 MASK & N95 FACE MASK Frequently asked questions
In April 2020, Kn95 respirator masks were distributed world wide to help fight the COVID-19 pandemic. Regulations GB2626-2006, GB262-2019, & GB19083-2010 govern their production
Since they meet FDA guidelines they are extensively used by health-care professionals in the US. The KN95 respirator features a tight face fit to create an airtight seal. The KN95 features an earloop fastener, to distinguish it from N95 masks with head straps. Many favor the KN95 mask design due to how easy to put on. It also fits very well from the nose to the chin area stopping airborn particulates from bypassing the mask filter.
The ’95” in “KN95” indicates that it stops 95% of all particles greater than 0.3m in diameter. This means it is an effective barrier against bacteria, viruses, pollution particles, fine particles, dust, smog, pollen, and reduces the risk of bacteria and viral infections
KN95 respirators are multiple layered masks, typically having 5-layer protection. Layers are typically high-quality, nonwoven fabric, hot air cotton, & melt-blown fabric. Whereas the non woven material is hydrophobic & water & droplet proof, the hot air cotton is soft, which slows down air velocity.
Further layers facilitate particle filtration and being hypoallergenic materials, are skin-friendly. Such a layered fabric design contributes to the mask’s efficient particle filtering and generally better design. Further enhancing this design, the KN95 is foldable and features a bendable nose bridge to ensure a tight fit.
The WHO has provided guidance and available evidence when it comes to the use of face masks like the KN95 face mask as a protective measure against COVID-19. So far, it appears that these measures should be effective to prevent virus transmission and infection.. These masks are being used in New Chinatown 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 evaluate the effectiveness of respiratory masks like the N95 or KN95 against Coronavirus in particular. However, they advise that these masks should be worn to prevent infection transmission and virus transmission among health care workers, patients and the general public.
Both the US N95 and Chinese KN95 masks are manufactured and designed for to be used only once. This means that each new use would normally require a new mask. However, because of the shortage of 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 if stored properly and if used by one 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 mask designs filter at 95%+ efficiency. This makes them as good as the N95 masks and better than surgical masks (95% filtration efficiency) and PM 2.5 filter masks (having 60% +/- efficiency). KN95 masks have proven effective in filtering out airborne particles, viruses, and bacteria as proven by tests in accordance to international standards by regulators such as the FDA and CDC.
Studies however show that filter mask efficiency drops considerably after sterilization or extended use. The simple reason, filtering facepiece respirators are created for one time use only and should then be disposed of.That is why discretion should be exercised when reusing or sterilizing respiratory masks.That is why the CDC suggests extended use only if the mask continued to fit and function well and is properly stored between use (if it’s being reused).
These are the recommendations from the CDC for handling a decontaminated mask:
- Wash your hands with soap and water or a 60% alcohol based sanitiser before and after touching or adjusting the respiratory mask.
- Avoid touching your mask.
- Wear a pair of clean non-sterile gloves when touching or adjusting the mask.
- Make sure your mask fit or structure has not been compromised in any way.
- Look at the mask components, the material, the straps, the nose bridge to see if mask structure, efficiency or fit has been compromised in any way.
- 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 the same and because of the high demand for certified masks it is quite likely some are counterfeit. How can one tell?
- The respiratory face mask is approved for use by children. No masks have been sanctioned by NIOSH for use by children.
- Attached to the respirator are decorative attachments or fabrics.
- On the packaging or box is printed an FDA logo. (The FDA does no authorize the use of their name or label on any respirator packaging).
- KN95 Masks don’t have a TC number or NIOSK logos on them, only N95 masks made for the US market do.
- The filtering face piece respirator mask has no markings on it *.
- There are straps for ears instead of earloops for KN95 masks.
If you suspect your KN95 face-mask is not genuine, you can do these additional tests:
Flammability: A certified KN95 mask will melt but not ignite. Counterfeit KN95 masks made from cheap materials will ignite if exposed to a flame.
Permeability: The ability to limit airflow, one can test by using the flame of a lighter or candle. See if you can blow out the flame by blowing through the mask. With a genuine KN95 mask this will be not possible.
Liquid Resistance: A certified KN95 mask has a layer in it that will prevent fluid from passing through. To check this, * pour water into the mask, a genuine KN95 will not allow any water to flow through.
To put the KN95 mask properly :
- First make sure you wash your hands completely using an alcohol based sanitizer or soap and water.
- Holding the inside of the KN95 mask facing up, tuck the mask under the chin.
- Take the ear loops and stretch it around each ear.
- Pushing downwards and on each side of the nose piece, adjust it to your nose with both hands.
- To ensure a good fitting, your respirator must seal properly. With both hands on the mask, exhale. Readjust the fit if air escapes, 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.
