The Positive Aspects of a Kn95 Mask

A Kn95 mask is a widely-used, short-name title for a Kn95 face mask, a full-face respirator that meets current Chinese standards for protecting the health of those who wear it. The Kn95 refers to the protective equipment standard issued by the Environmental Protection Agency (EPA). This is the standard used to designate certain materials and equipment that are considered hazardous and require a certain level of protection for the public from exposure to these hazardous materials. Generally, this requires that the materials be filtered through a Kn95 filter to provide protection against particles up to 0.3 micrometers in diameter.
