ASHRAE EPIDEMIC TASK FORCE
www.ashrae.orgHigh Efficiency Particulate Air (HEPA) Filters •HEPA filter efficiency is higher than MERV 16. •It is usually not feasible to retrofit existing HVAC systems with HEPA filters due to high pressure drops and the likelihood that systems will need new filter racks to allow sufficient sealing to prevent filter bypass.
Q2: How often should HVAC filters be changed?
www.ashrae.orgparticles of concern. High-efficiency particulate air (HEPA) filters are even more efficient at filtering human-generated infectious aerosols. By definition, a HEPA filter must be at least 99.97% efficient at capturing particles 0.3 µm in size. This 0.3 µm particle approximates the most penetrating particle size (MPPS) through the filter.
