Choosing Right KN95 Face Mask That Fits Your Face

KN95 mask, commonly spelt as KN95 mask, is a protective facepiece that meets the Chinese classification of workplace respiratory protection, which means it effectively filters at least 95% of all airborne particles present in the workplace. KN95 stands for "no dust" since the material is designed to keep dust particles out of the air we breathe. The term "dust" refers to microscopic dust particles, including in many cases, dust mite faeces. It is estimated that over two million people died from diseases caused by inhaling small particles of dust in the work place. The majority of these deaths could have been prevented if the employers used a dust control mask.

KN95 masks are available in three different styles to match the needs of the wearer. There are face masks, which cover the entire head; upper chest respirators, which cover the torso; and full face respirators, which cover the eyes. All KN95 masks must meet certain criteria to be approved for use in the U.S., and KN95 certification is obtained from a national accrediting agency. Before purchasing an KN95 mask, you should check with your local department of labor or visit the website of the U.S. Occupational Safety and Health Administration (OSHA). Either way, here are a few things to consider before purchasing.

Basic reasons for which one can use face masks

KN95 masks can be worn for several reasons, but the most common reason for purchasing one is the prevention of dust allergy or induced asthma attacks. A common factor among dust particles is air-borne bacteria, which can irritate the nose, skin, eyes, throat and possibly the lungs. Some dust particles are too large to penetrate the outer layer of the skin. However, some tiny particles can fit through the skin and enter the respiratory system. KN95 masks can prevent such particles from entering the respiratory system.

Another reason for the use of KN95 masks is to protect the eyes from airborne allergens. Allergic reactions to airborne allergens can trigger an asthma attack or cause an emergency reaction in the chest, leading to a loss of oxygen. A full face mask, which contains a pair of fully sealed airtight plastic airways, provides excellent protection against airborne allergens, as well as preventing irritants from penetrating the skin. There are two types of masks that have a valve at the top: the standard non-valved respirators, and the valved respirators.

Chose the best standard KN95 masks for better protection

When faced with this fact, it is better to choose the standard KN95 mask rather than face masks that contain a valve. Standard KN95 coverings are available in both disposable and reusable varieties. Disposable coverings are used once and must be discarded, while reusable coverings can be reused over again. For example, disposable face masks can be worn for one hour and then replaced with a fresh new one. This is more convenient than buying several different disposable masks.

As for the filtration of dust and other particles, the American Noll Technical Standards (ASTM) recommend the use of an NPS filter for this purpose. However, according to the American Noll Technical Standards, the EPA has set the maximum acceptable dust concentration at 0.3 micrometers or less. According to amin says, "The higher the concentration, the more effective the filter will be." Amin says that the use of NPS and EHMA filters, alone or together, will provide the best protection against occupational exposure to dust and other fine particles.

The key is to choose a KN95 mask that fits well. If you can't find one that fits well, try one that is made from special synthetic material. According to the specifications of the American Society for Testing and Materials (ASTM), KN95 masks that are made from polyvinyl chlorides are effective for reducing airborne dust and other fine particles. Based on the specifications of the ASTM, these masks should have an airflow ventilation of at least 40% of the normal room temperature, an easily adjustable fit, a tight seal, and air-tight covering.
