KN95 MASK & N95 FACE MASK Frequently asked questions
In April 2020, Kn95 respirator masks were distributed world wide to help fight the COVID-19 epidemic. 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 mask features a tight face fit and thus create an airtight seal. This mask features an earloop fastener, unlike 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 preventing airborn particulates from bypassing the masks’ filter.
The KN95 is your first defense against air borne particles including viruses and bacteria stopping 95% of all particles greater than 0.3m in diameter. Thus the KN95 mask is an effective barrier to bacteria, viruses, pollution particles, fine particles, dust, smog, pollen, reducing the risk of viral and bacteria infections
Typically Kn95 masks have 5 layers of protection. The materials commonly used is nonwoven fabric, hot air cotton, & melt-blown fabric. Whereas the non woven fabric is hydrophobic & water & droplet proof, the hot air cotton is soft, which slows down air velocity.
Deeper 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 superior design. Further enhancing this design, the KN95 is foldable and features a bendable nose bridge to ensure a tight fit.
As a preventive measure against COVID-19 the WHO has recommended respiratory face masks. From the evidence the WHO have given * KN95s masks are effective against virus transmission and infection. These masks are being used in Los Angeles 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 encouraged. However, the WHO states and emphasizes that there are not enough evidence to evaluate the effectiveness of respiratory masks like the KN95 or N95 against Coronavirus in particular. Despite this as an emergency measure against Covid-19 and face masks are recommended.
Even though the KN95 & N95 respiratory masks are designed for a one time use, in light of COVID-19 Crisis and the shortage of PPE supplies, the CDC recommends reuse. Measures for extending mask use can be found at The National Institute for Occupational Safety and Health (NIOSH).
One may reuse ones’s KN95 or N95 face mask according to NIOSH but only if stored properly and if only used by one individual. It may also be used extensively for one day but then the mask must be disposed of.
KN95 masks have a filter efficiency of 95%+ making them as good as N95 masks and better than surgical masks (95%) & PM 2.5 filter masks (60%). KN95 masks have proven effective in filtering out airborne particles, viruses, and bacteria as proven by tests governed by regulators such as the FDA and CDC.
However, studies have shown that the filtration efficiency drops after sterilization or extended use. The filtration efficiency can drop more than 50% post-sterilization. The simple reason, KN95 & N95 face masks 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 maintains its fit and function and is properly stored between use (if it’s being reused).
Follow these recommendations by the Center of Disease Control (CDC) for handling a decontaminated mask:
- Using soap and water or a 60% alcohol based sanitiser clean your hands before and after touching or adjusting a respiratory mask.
- Avoid touching the inside of your mask.
- Wear a pair of clean non-sterile gloves when touching or adjusting the mask.
- Ensure one’s face-mask fit or structure has not been compromised in any way.
- Check to ensure if the mask components like the nose bridge, straps, and nose foam material did not degrade (which can compromise mask efficiency, fit, and seal).
- Always make sure to discard a used respiratory mask properly and never leave it exposed, where other people can touch it or reuse it.
Not all KN95 masks and brands on the market are authentic, and due to the shortage of the masks, there are many counterfeit KN95 mask brands. Some of the signs that a respiratory mask is counterfeit are the following:
- The respiratory face mask is approved for use by children. No masks are approved by NIOSH for use by children.
- The face-mask has decorative fabric or decorative attachments, e.g. sequins.
- A FDA logo is on the box or packaging; FDA does NOT approve the use of their administration label on any respirator packaging,
- There is a TC number or NIOSH logo on a KN95 face-mask. (Only an US market N95 mask has a NIOSH logo).
- There are no marking on the filtering face piece respirator mask at all.
- Instead of ear loops the KN95 mask has straps. There are no straps on a KN95 respirator mask.
If you wish to ensure your face-mask is not fake you can do these additional tests:
Flammability: The material in a certified KN95 respirator will melt but not ignite when exposed to an open flame. Non-genuine masks will burn when exposed to an open flame.
Permeability: A certified KN95 face mask should restrict the airflow going in and out of the mask. Test this by trying to blow out the flame of a lighter or candle by blowing through the mask. With a KN95 rated face mask, you shouldn’t be able to blow out the flame no matter how hard you blow.
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 some water into the mask. If certified the KN95 mask will contain all water with no leakage, while a counterfeit mask will allow water through.
To properly put on a face mask do this:
- Before touching one’s face mask, be sure to wash your hands. Use a 60% alcohol-based sanitizer or soap and water.
- With the inside of the KN95 mask facing up, place the mask under the chin.
- Holding the ear loops, stretch it each ear.
- Using your hands adjust the nose piece to the shape of your nose.
- For your respirator mask to operate properly, you must always check the fit to see if it seals properly. With out changing the mask’s position, with both hands on the mask, exhale. If air leaks adjust it, pay particular attention 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.” Listed by FDA here are their approved KN95 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.
