KN95 MASK & N95 FACE MASK Frequently asked questions
KN95 masks since April 2020 have become available through the Chinese Government to help fight the COVID-19 pandemic. Their production is governed by regulations GB2626-2006, GB262-2019, and GB19083-2010.
Healthcare workers extensively use the KN95 face masks since they meet the FDA guidelines and international standards in the US. The KN95 face mask fits tightly around the face to create an airtight seal. The KN95 features an earloop fastener, unlike N95 masks with head strap attachments. Many favor the KN95 mask design as it is easy to put on. It also fits very well from the nose to the chin area preventing particles from bypassing the mask 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. Therefore not only will the KN95 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 materials commonly used is nonwoven fabric, hot air cotton, and melt-blown fabric. Whereas the non woven material is hydrophobic and water and droplet proof, the hot air cotton is soft, which slows down air velocity.
Additional hypo-allergenic layers are skin-friendly and deter further particle penetration. This type of multi-layered design contributes to a superior mask design. Further enhancing the KN95 design is foldable and features a bendable nose bridge to ensure an air-tight fit.
As a preventive measure against COVID-19 the World Health Organization has recommended respiratory face masks. From the evidence the WHO have given it appears KN95s masks are effective against virus transmission and infection. These KN95 masks are being used in Downtown 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 recommended. However, the WHO maintains and emphasizes that there are currently NOT ENOUGH studies to determine conclusively the effectiveness of respiratory masks like the KN95 or N95 against the Corona virus in particular. Nevertheless the WHO still advise that respiratory masks be used to prevent COVID-19.
Both the US N95 and Chinese KN95 masks are engineered 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 the extended use of masks for the N95 or KN95 are available 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 person. It may also be used extensively for one day but then the mask must not be reused.
KN95 masks filter effiency is 95%+ making them as effective as N95 masks and better than PM 2.5 filter masks (60%) and surgical masks (95%) KN95 masks have proven effective against airborne viruses, bacteria and particulates as proven by tests governed by regulators such as the FDA and CDC.
Studies do show however that filter mask efficiency drops considerably after sterilization or extended use. The simple reason, KN95 & N95 face masks are designed for one-time use and should then be disposed of.That is why discretion should be exercised when reusing or sterilizing respiratory masks.That is why the CDC recommends extended use only if the mask maintains its fit and function and is properly stored between use (if it’s being reused).
According to the Crisis Standards of Care by the Center of Disease Control (CDC), one should follow these measures:
- Before and after touching and adjusting a respiratory mask, you should clean ones hands with soap and water, or a 60% alcohol-based sanitizer.
- Avoid touching the inside of ones’s mask.
- When touching and adjusting one’s mask, use clean (non-sterile) gloves.
- Make sure one’s mask stucture and/or fit has not been compromised in any way.
- Ensure that the integrity of the mask structure fit and material has not been compromised.
- Discard a used face mask properly and never leave it exposed, where other people can touch it or reuse it.
No KN95 masks or brands are created equal, and due to the shortage of the masks, there are many counterfeits. Some of the signs a mask is counterfeit are:
- The respiratory face mask has official approval for use by children. No masks are approved by NIOSH for children.
- Presence of decorative fabric or other decorative add-ons (e.g. sequins),
- 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.
- One can see no marking on the face mask whatsoever.
- There are straps instead of ear loops on the KN95. There are no straps on a KN95 respirator mask.
If you wish to ensure one’s face-mask is not fake you can do these additional tests:
Flammability: if a mask is KN95 certified when exposed to a flame it should melt but not ignite. Counterfeit KN95 masks made from cheap materials will ignite if exposed to a flame.
Permeability: if a mask is KN95 certified, it restricts the airflow. Test this by trying to blow out the flame of a lighter or candle by blowing through the mask. With a certified KN95 mask, you shouldn’t be able to blow out the flame no matter how hard you blow.
Liquid Resistance: A Certified KN95 mask will have a layer that will prevent fluid to pass through. One can test this by pouring some water into the mask. If certified the KN95 mask will contain all the water without leaking, while a counterfeit mask will allow the water to flow through the mask.
To properly put on a respiratory KN95 follow these steps:
- First make sure you wash one’s hands thoroughly with an alcohol based sanitizer or soap and water.
- With the inside of the respirator mask face up, tuck the mask under the chin.
- Place the earloops over each ear.
- Using your hands place and adjust the mask on your nose. You should mold the nosepiece to the shape of your nose and push downwards on both sides of the nosepiece.
- To ensure a proper fit, your face-mask 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.
