KN95 Protective Mask is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles includes PM2.5 dust and bacteria / virus / Coronavirus Disease 2019 (COVID-19).

The 4-ply foldable face mask has a filtration efficiency of greater than/equal 95%, to protect against microns greater than 0.3 in. size, effectively protecting respiratory health. The masks help prevent the spread of germs and protect yourself from airborne particles and allergens.

In response to the crisis, the CDC has listed KN95 masks as an alternative to N95 masks and after comparing the masks, a technical bulletin from 3M™ confirms that “it is reasonable to consider China KN95….as equivelant to US NIOSH N95 and European FFP2 respirators.”

Specifications:

• Filter Level: >95% (0.3 Microns – MPPS, the most difficult particle size to capture)
• Standard: GB2626-2006 are called KN95
• Made of high-quality materials, safe, soft and comfortable.

Is this masks medical grade?

These masks are non-sterile and should NOT be used for surgical procedures. For the purposes of the current global pandemic these masks offer good general protection.

• GB 19083-2010 is the alternative protective face mask standard for medical use that filters particulate matter in the air, and block the droplets, blood, body fluids, secretions etc (in the medical working environment).

Fabric Face masks help us greatly reduce the spread of the virus by catching most the droplets when we talk, sneeze or cough.

They can also act as a barrier between the mouth and nose of a wearer and contaminants in the immediate environment

(They are not medical and DO NOT guarantee that the wearer will be protected against contamination of infection that may exist).

What is N95 / KN95 and what does it have to do with medical protective masks?

The N95 mask is one of nine anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health). Particulate matter protective masks, commonly known as dust masks, are a kind of special labor protection products. Domestic production of particulate matter protective masks requires an industrial product production license, and the products should meet the mandatory national standard GB2626-2006.

The N95 mask has a filtration efficiency of more than 95% for particles with an aerodynamic diameter ≥ 0.3µm. The aerodynamic diameter of air bacteria and fungal spores mainly varies between 0.7-10µm, and it is also within the protective range of N95 masks. Therefore, N95 masks can be used for respiratory protection of certain particulates, such as dust generated during grinding, cleaning and processing of minerals, flour and certain other materials. It is also suitable for liquid or non-oily non-production caused by spraying. Hazardous volatile gas particles. Can effectively filter and purify the inhaled abnormal odors (except toxic gases), help reduce the exposure level of certain inhalable microbial particulates (such as mold, anthrax, tuberculosis, etc.), but cannot eliminate contact infection, illness or death risks of.

The US Department of Labor has recommended that medical personnel use N95 masks to prevent microbial airborne diseases such as influenza and tuberculosis. Take coronavirus as an example (2019-nCoV is a kind of coronavirus), with an average diameter of about 100nm, that is, 0.1.um, plus a propagation vector, such as droplets of about 1-5um in diameter, and N95 filters 0.3um non-oily particles With an effect of ≥95%, N95 can achieve effective filtration.

In response to the crisis, the CDC has listed KN95 masks as an alternative to N95 masks and after comparing the masks, a technical bulletin from 3M™ confirms that “it is reasonable to consider China KN95….as equivelant to US NIOSH N95 and European FFP2 respirators.”

Do I have to buy a mask with the highest level of protection?

When wearing a medical mask, you should choose the appropriate level and type according to the type of transmission of the pollutant and the risk. Although the medical protective mask with high protection level has better protection effect, because of the high filter material level, good adhesion and higher breathing resistance, long-term wearing will increase the burden of breathing, causing difficulty in breathing and other discomforts. At the same time, breathability and Hygroscopicity is also worse, which means worse comfort.

Medical surgical masks and medical protective masks can block the pollution caused by blood and body fluid splashes, but if you really need to block the pollution of airborne particles and pathogenic microorganisms, please choose to wear medical protective masks.

Sort according to protection level from high to low: N95 / KN95 (Medical Protective Masks) ＞ Medical Surgical Masks ＞ General Medical Masks ＞ Other various three non-masks ＞ None

How often is the N95 / KN95 mask should be replaced or changed?

The protective effect of any type of mask is time-consuming and must be replaced regularly. It is currently in a special period. In many popular videos of wearing masks, it is reminded repeatedly that masks must not be reused. It is recommended to replace the masks every 2 to 4 hours. If the mask is contaminated, it should be replaced immediately.

The sections of gray typeface below are the definitions of the frequency of changing masks in ordinary times.

At present, there is no clear conclusion on the optimal wearing time of N95 masks by foreign countries including WHO, and there is no relevant regulation on the use time of masks in China.

The National Institute for Occupational Safety and Health (NIOSH) requires the replacement of medical protective masks in the following situations:

① When contaminated with blood, body fluids and other infectious agents of patients.

② When the mask is damaged.

③ When significant respiratory resistance increases.

④ The heavily polluted working environment will result in a relatively high filtration load. Therefore, the use time of N-series masks can only be extended to 8 hours, including continuous or intermittent use.

However, the current domestic GB19083-2010 “Technical Requirements for Medical Protective Masks” does not make requirements on whether medical protective masks can be reused and wearing time. WS / T311-2009 “Hospital Isolation Technical Specifications” proposes “The effectiveness of medical protective masks Continue to apply for 6 to 8 hours. In case of pollution or humidity, it should be replaced in time. “

Research conducted by Beijing Municipal Tuberculosis and Thoracic Tumor Research Center Du Jian and others showed that the filtering efficiency of medical protective masks gradually decreased with the use of time. On the third day, the average filtering efficiency was 94.7%; after 5 working days, filtering The efficiency is reduced to 92.0%; the filtration efficiency is still above 80.0% (80.6%) after 14 working days, so it is pointed out that the medical protective mask can still meet the design requirements when worn for 3 days, and based on cost-benefit considerations, the study proposed that Replacement frequency of 2 medical masks in 5 working days.

Mask management

For any type of mask, appropriate use and disposal are essential to ensure that they are effective and to avoid any increase in transmission. The following information on the correct use of masks is derived from practices in health care settings.

• Place the mask carefully, ensuring it covers the mouth
  and nose, and tie it securely to minimize any gaps
  between the face and the mask.
• Avoid touching the mask while wearing it.
• Remove the mask using the appropriate technique: do not
  touch the front of the mask but untie it from behind.
• After removal or whenever a used mask is inadvertently
  touched, clean hands using an alcohol-based hand rub or
  soap and water if hands are visibly dirty.
• Replace masks as soon as they become damp with a new
  clean, dry mask.
• Do not re-use single-use masks.
• Discard single-use masks after each use and dispose of
  them immediately upon removal.
