Air filtration removes contaminants, including viruses, bacteria, and other harmful particles. By removing these particles from the air, air filtration systems can reduce the concentration of airborne viruses and other pathogens, which can help to prevent their transmission.
One of the key benefits of air filtration is that it can be used in various settings, including homes, schools, hospitals, and other public spaces. Different air filtration technologies are available, each with its strengths and limitations.
According to research on other common viruses, droplets as small as 1.0 microns can carry enough viruses to cause infections.
Droplets typically expelled by people suffering from respiratory infections range in size from 0.5 to 15 microns, with the majority falling in the lower ranges.
A virus is typically contained within a respiratory droplet or aerosol, making it the target particle that must be removed from the air. Camfil recommends filters with an ISO16890 rating of at least ePM1 60% (MERV 13A).
Suppose the current configuration of the HVAC ventilation system allows it. If possible, a prefilter with a minimum rating of ISO16890 ePM1-50% (MERV 8A) should be installed upstream to extend the service life. In that case, the efficiency recommended by ASHRAE for common risk areas such as commercial office and retail buildings, schools, airports, and manufacturing facilities is ePM1 60% (MERV 13A) or higher.
