Hepa Air Filtration System Coronavirus

There is conflicting information surfacing about the role and efficacy of air filters.

Hepa air filtration system coronavirus. As with building filtration the details are important e g efficiency and airflow rate of the air cleaner sizing and. Deploying a temporary hepa air filtration system in large public places to help reduce the spread of the coronavirus makes sense. Hepa which stands for high efficiency particulate air filters are rated at the top of their class for their ability to trap tiny particles in the air around at least 99 97 theoretically. Air cleaners hvac filters and coronavirus covid 19 air cleaners and hvac filters are designed to filter pollutants or contaminants out of the air that passes thru them.

Air purifiers with hepa filtration efficiently capture particles the size of and far smaller than the virus that causes covid 19 and many readers have asked whether air purifiers can help. James dickerson cr s chief science officer echoes the consensus that air purifiers could help in some situations but with a caveat. For government facilities supermarkets drug stores airport check in areas and other places that need to stay open bluesky offers temporary hepa air filtration systems designed to handle up to 25 000 scfm of contaminated air per machine. No system has been proven to filter covid 19 as of yet as it is a new virus.

Hepa stands for high efficiency particulate air hepa filters are physical filters designed to clear out at least 99 7 percent of particulates that are 0 3 microns or larger in size. Air filtration and covid 19. Their removal rate is appropriate for the room maintained and operated portable hepa filters. The coronavirus covid 19 falls in between 0 06 micron 60 nanometers and 0 14 micron 140 nanometers in diameter.

Hepa filters are very efficient at catching coronavirus. In a 2016 study by nasa it was tested and proven that hepa filters were most efficient almost 100 at filtering particles at 0 01 micron below the normal 0 3 test standard for hepa filters. Which hepa air purifiers can filter out the covid 19 virus. But there is research supporting an air purifier s ability to filter common airborne viruses as long as the infected air is captured by the system.

Which is to.
