A: Although ASHRAE does not recommend a specific MERV filter rating for preventing COVID-19 transmission, the organization suggests that upgrading systems in non-healthcare facilities to MERV-13 or the highest achievable level can be a worthwhile step in emergency response plans. If possible the air should be externally vented after passing through a filter with a MERV rating* of at least 17. Air exhaust should also be … It’s an acronym created by ASHRAE to provide a scale showing the effectiveness of filters at removing particles of different sizes. This paper. ). ULPA is an acronym for "Ultra-low Penetration Air (filter)".An ULPA filter can remove from the air at least 99.999% of dust, pollen, mold, bacteria and any airborne particles with a minimum particle penetration size of 120 nanometres (0.12 µm, ultrafine particles).A ULPA filter can remove (to a large extent, not 100%) – oil smoke, tobacco smoke, rosin smoke, smog, insecticide dust. The higher the MERV rating the more efficient the filter will be at capturing airborne particles. We’ll look at MERV 1-20 ratings in the MERV rating chart (you’ll find the chart further on). The majority of residential HVAC systems use a 1” thick filter, but filters are available at 2”, 4” and 5” thick. With finer filtration, fewer airborne contaminates & dust particles are allowed to pass through the filter. The range of sizes in the MERV scale is 0.3 µm to 10 µm, subdivided into smaller ranges.
