HEPA filters are critical in the prevention of the spread of airborne bacterial and viral organisms and, therefore, infection. Typically, medical use HEPA filtration systems also incorporate high-energy ultraviolet light units or panels with anti-microbial coating to kill off the live bacteria and viruses trapped by the filter media.

HEPA filters are high-efficiency filters designed to control the number of particles entering a clean area by trapping both larger and smaller particles through a combination of outer filters and dense fiber mats, making them effective in removing a high percentage of particles from the air.
The short answer is that, by definition, HEPA filters can effectively filter out all particles (including solid-form viruses) that are 0.3-micron in diameter. However, it’s vital to understand that the FDA has to approve an air purifier to be used as a medical device against coronavirus.
19 mar 2020 · We call this "medical-grade" HEPA filtration. You may be aware that there's a filter that removes even smaller particles, called the ULPA (Ultra-Low Particulate Air) filter. The ULPA standard requires removal of 99.999% of particles down to 0.12 microns.
18 kwi 2024 · HEPA air filter. Overview. A HEPA (High Efficiency Particle Arresting) filter can remove the majority of harmful particles, including mold spores, dust, dust mites, pet dander and other irritating allergens from the air.
19 lut 2024 · In this comprehensive look, we’ll explore why HEPA filters are the preferred choice in healthcare settings and how they function to ensure air safety. Decoding HEPA: How These Filters Transform Healthcare Air Quality. HEPA filters are more than just air filters; they are a critical component in maintaining a sterile environment.
HEPA filters remove airborne contaminants that could compromise the health of staff performing important procedures or patients when their internal organs are exposed in surgical operations.
