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.
Kn95 masks are worn by individuals as protection against airborne particles. They may also be worn for the prevention of colds and flu. They are often used to protect infants and young children by reducing the rate of asthmatic attacks when they become exposed to dust and other respiratory irritants. Kn95 masks are available in various styles and are designed to meet the specific breathing requirements of adults and children.
The Kn95 filter system has three major components: the facemask, the supplying cap, and the respiratory mask or the Kn95 mask. The material used to make these masks is polypropylene (PP), which is approved by the FDA. Several studies have indicated that Kn95 masks to reduce the risk of infections by up to 95% when used while treating patients with acute respiratory illness. A separate type of Kn95 mask called an aerosol Kn95 filter is available that is more efficient at filtering down more dangerous airborne particles than are conventional facemasks.
What to consider before buying the mask
The Kn95 mask has a liner that should be considered when purchasing. The size of the liner is dependent upon the amount of air flowing through the respirator. When the airflow is insufficient, the particles can gather along the inside of the respirator and become trapped. This will cause the closing of the breathing passageway through the mask, thereby reducing airflow. A larger liner will prevent the particles from becoming trapped.
Many healthcare workers who wear disposable Kn95 respirators suffer from allergy symptoms during the time that they are wearing the masks. During the first few days after wearing the protective equipment, some of these individuals may experience eye irritation or inflammation at the point of contact with the mask. Caffeine and salt are both common irritants that can be found in the makeup of many disposable Kn95 masks. To address this problem, many healthcare workers opt for an improved respirator design. Advancements in technology have led to the development of more comfortable Kn95 respirators that feature soft linings that make contact with the wearer’s eyes less irritating.
There are many other positive aspects to the design of a Kn95 mask. Kn95 masks are designed to provide a high level of protection against particulates, bacteria, and viruses that can become airborne during a biological hazard event. The positive pressure check ensures that there is no escape of gaseous or particulate matter from the mask. Kn95 masks may be worn by healthcare workers who work in hazardous environments, such as those that are contaminated with blood, are involved in spill response, or are required to wear protective gear in the workplace.
