What is a respirator?

A respirator is a personal protective device that is worn on the face or head and covers at least the nose and mouth. A respirator is used to reduce the wearer’s risk of inhaling hazardous airborne particles (including infectious agents), gases or vapors. Respirators, including those intended for use in healthcare settings, are certified by the CDC/NIOSH.


What is an KN95 filtering facepiece respirator (FFR)?

A KN95 FFR is a type of respirator which removes particles from the air that are breathed through it. These respirators filter out at least 95% of very small (0.3 micron) particles. KN95 FFRs are capable of filtering out all types of particles, including bacteria and viruses.


What makes KN95 respirators different from facemasks (sometimes called a surgical mask)?

N95 respirators reduce the wearer’s exposure to airborne particles, from small particle aerosols to large droplets. N95 respirators are tight-fitting respirators that filter out at least 95% of particles in the air, including large and small particles.

When properly fitted and worn, minimal leakage occurs around edges of the respirator   when the user inhales. This means almost all of the air is directed through the filter media.

Facemasks or surgical masks are loose-fitting and provide only barrier protection against droplets, including large respiratory particles. No fit testing or seal check is necessary with facemasks. Most facemasks do not effectively filter small particles from the air and do not prevent leakage around the edge of the mask when the user inhales.

The role of facemasks is for patient source control, to prevent contamination of the surrounding area when a person coughs or sneezes.  Patients with confirmed or suspected COVID-19 should wear a facemask until they are isolated in a hospital or at home. The patient does not need to wear a facemask while isolated.


KN95 respirators are hot and uncomfortable - what can I do?

The requirements for surgical N95 respirators that make them resistant to high velocity streams of body fluids and help protect the sterile field can result in a design that has a higher breathing resistance (makes it more difficult to breath). Some KN95 respirators are designed without exhalation valves which are sometimes perceived as warmer inside the mask than typical KN95 respirators.


Some KN95 respirators have an exhalation valve - is that okay?

Both masks provide the same level of protection to the wearer as one that does not have a valve. The presence of an exhalation valve reduces exhalation resistance, which makes it easier to breathe (exhale). Some users feel that a respirator with an exhalation valve keeps the face cooler and reduces moisture build up inside the facepiece. However, respirators with exhalation valves should not be used in situations where a sterile field must be maintained (e.g., a COVID19 infected person wearing a mask with exhalation valve may contaminate the environment by sneezing, coughing and exhaling the droplets which may infect others in the surrounding) because the exhalation valve allows unfiltered exhaled air to escape into the sterile field.


Are the masks reusable? 

As per the recommendations, KN95 respirators can function within their design specifications for 8-12 hours of continuous or intermittent use and should not be reused after that. The maximum length of continuous use in non-dusty healthcare workplaces is typically dictated by hygienic conditions and can be determined depending on the environments. 

KN95 masks should be discarded properly once used. The facemask should be removed and discarded if soiled, damaged, or hard to breathe through. Wearer must take care not to touch their facemask, if they touch or adjust their facemask they must immediately perform hand hygiene.



What is the difference between N95 and KN95 mask?

N95 masks are the US standards for respirator masks; KN95 masks are the Asian standards for masks. Despite the minimal differences, the two masks are equivalent or nearly equivalent on all the safety features.


Are these masks certified?

These respirators are CE certified with FDA approved design.


What is the difference between gowns and coverall suits?        

Coveralls/Suits typically provide 360-degree protection because they are designed to cover the whole body, including the back and lower legs, and sometimes the head and feet as well. Surgical/isolation gowns do not provide continuous whole-body protection (e.g., they have possible openings and typically provide coverage to the mid-calf only).

Gowns are easier to put on and, in particular, to take off. They are generally more familiar to healthcare workers and hence more likely to be used and removed correctly. Surgical/isolation gowns do not provide continuous whole-body protection (e.g., they have possible openings and typically provide coverage to the mid-calf only).
