An air filter’s MERV rating is a scale from 1-16 that describes the minimum efficiency of the air filter. stream The Minimum Efficiency Reporting Value (MERV) rating of a filter measures how efficiently it removes contaminants from the air stream based on the size of the particles it can effectively capture. The answer depends on the equipment application. Some filters have a static electrical charge applied to the media to increase particle removal. The higher the MERV value is the more efficient the filter will be in trapping airborne particles. 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. մP- jЪoCe-N�"�Cf, .V��x5~��Š�$�cJ��?\�:���N�>�W������S�~a q���qz:�W�{�G�T�{m$䶞�cz�!?

ASHRAE suggests using the highest-rated Minimum Efficiency Reporting Value (MERV) filter recommended by your HVAC manufacturer. Here’s an in-depth description of the process used to determine MERV, from the National Air Filtration Association: I've heard that ASHRAE is planning to recommend a minimum of MERV-14 for better filtration of coronavirus. ^�,����|-f\t&al��/�(ƃ�b����A ;���#�� �B�_�U�o���o���/޸�����=q�/���n�؏�����z�{�[g�0^5���Š�YR:�;��7�MZҫ���u1?
