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. They are produced under regulations GB2626-2006, GB262-2019, and GB19083-2010
Healthcare workers extensively use the KN95 filtering facepiece respirators since they meet the FDA guidelines and international standards in the US. The KN95 face mask features a tight face fit to create an airtight seal. This mask features an earloop fastener, to distinguish it from other types of masks with head straps. 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 airborn particulates from bypassing the mask filter.
The ’95” in “KN95” indicates that it stops 95% of all particles more than 0.3m in diameter. This means it is an effective filter against 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 fabrics commonly used is hot air cotton, melt-blown nonwoven fabric. Whereas the non woven fabric is hydrophobic and water and 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 better design. Further enhancing this design, the KN95 is foldable and features a bendable nose bridge ensuring a tight fit.
As a preventive measure against COVID-19 the WHO has recommended KN95s. From the evidence the WHO have given it appears face masks are effective against virus transmission and infection. These masks are being used in Pico Gardens by health care providers. And since it is believed that 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 N95 or KN95 against the Corona virus in particular. Nevertheless the WHO still advise that respiratory masks be used as a preventative measure against COVID-19.
Both the N95 and KN95 masks are intended for one-time use (disposable design). This means that each new use would normally require a new mask. However, since there is a 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 can be found at The National Institute for Occupational Safety and Health (NIOSH).
NIOSH states that N95 and KN95 masks may be reused if stored properly and if only used by one individual. Someone can use a mask for an extended period for one day after which the mask should be disposed of.
KN95 masks have a filter efficiency of 95%+ making them as good as N95 masks and better than surgical masks (95%) and PM 2.5 filter masks (60%). KN95 masks are very effective against 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 of KN95 masks drops after sterilization or extended use. The filtration effectiveness can drop more than 50% post-sterilization. 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).
Abiding by the CDC, decontamination recommendations in regards to handling a decontaminated mask are as follows:
- Using soap and water or a 60% alcohol based sanitiser clean your hands before and after touching or adjusting the respiratory mask.
- Avoid touching the inside of your mask.
- When touching & adjusting one’s mask, use a pair of clean (non-sterile) gloves.
- Ensure your mask stucture and/or fit has not been compromised in any way.
- It is important to ensure that the integrity of the mask structure fit and material has not been compromised.
- Always ensure you don’t leave a used face-mask where someone can touch or reuse it.
Not all KN95 masks or brands are created equal, and due to the demand for masks, there are many counterfeits. Some of the signs a mask is counterfeit are:
- Claims that the mask is approved for children (NIOSH does NOT approve respiratory protection for children).
- Attached to the respirator 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,
- There is a TC number or NIOSH logo on a KN95 respirator. (Only an US market N95 mask has a NIOSH logo).
- No markings on the face mask at all.
- There are straps instead of ear loops on the KN95. There are no straps on a KN95 respirator mask.
If you suspect your KN95 face-mask is not genuine, 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: 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 impossible.
Liquid Resistance: A certified 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 allow any water to flow through.
Fitting the KN95 properly make sure to do as follows:
- First make sure you wash your hands completely using an alcohol based sanitizer or soap and water.
- With the inside of the KN95 mask face up, tuck the mask under the chin.
- Place the earloops around each ear.
- Using your hands mold the nose piece to the shape of your nose.
- To ensure a proper fit, 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.” 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.
