The filtration efficiency of Disposable KN95 Mask for particles with aerodynamic diameter of 0.075µm±0.02µm is above 95%. The aerodynamic diameter of air bacteria and fungal spores mainly varies between 0.7-10µm, which is also within the protection range of Disposable KN95 Mask. Therefore, Disposable KN95 Mask can be used for respiratory protection of certain particles, such as dust generated by grinding, cleaning and processing of minerals, flour and certain other materials. Disposable KN95 Mask is also suitable for liquid or non-oily products caused by spraying Particulate matter that does not produce harmful volatile gases. Disposable KN95 Mask can effectively filter and purify the inhaled abnormal odors (except toxic gases), help reduce the exposure level of certain inhalable microbial particles (such as mold, anthrax, tuberculosis, etc.), but Disposable KN95 Mask does not eliminate contact The risk of sexual transmission, illness or death .
The US Department of Labor has recommended that medical staff use Disposable KN95 Mask to prevent microbial airborne diseases such as influenza and tuberculosis.
NIOSH certified other anti-particulate mask levels also include: N95, N99, N100, R95, R99, R100, P95, P99, P100, a total of 9 kinds. These protection levels can cover the protection range of Disposable KN95 Mask.
"N" means not resistant to oil, suitable for non-oily particulate matter.
"R" means resistant to oil, suitable for oily or non-oily particulate matter. If used for the protection of oily particulate matter, the use time should not exceed 8 hours.
"P" means oil proof, suitable for oily or non-oily particulate matter. If used for oily particulate matter, the usage time should follow the manufacturer's recommendations.
"95", "99" and "100" refer to the filtration efficiency level when tested with 0.3 micron particles. "95" means that the filtration efficiency is above 95%, "99" means that the filtration efficiency is above 99%, and "100" means that the filtration efficiency is above 99.7%.
