Efficiencies for MERV 15 and MERV 16 filters are even higher. ^�,����|-f\t&al��/�(ƃ�b����A ;���#�� �B�_�U�o���o���/�����=q�/���n�؏�����z�{�[g�0^5����YR:�;��7�MZҫ���u1? MERV 13 FILTERS MITIGATE VIRUSES Posted:03/29/2020. While there's no guarantee a strong air filter will protect you from the coronavirus, clean air helps keep your immune system strong. From a filtration point of view, the droplet is the particle that must be removed from the air. However, these recommendations are vague and appear to take a “one approach for all” method without considering the location and climate where the facilities ar… Of course, the ultimate choice needs to take the capabilities of the HVAC systems into consideration. •Some filters have a static electrical charge applied to the media to increase particle removal. endstream
One thing we need to make clear – this device is not a HEPA air purifier. 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. MERV 14 (or ISO equivalent) filters are preferred High efficiency particulate air (HEPA) filters are more efficient than MERV 16 filters. An air purifier can combat other causes of respiratory problems and improve the overall air quality in your home, but a standard HEPA filter can’t capture and destroy something as small as a virus. մP- j�ʶ�J��m�=ic2 MERV ratings detail a filter’s ability to capture particles, and higher-rated MERV filters are more efficient at capturing particles. HEPA is a type of pleated mechanical air filter. Research has shown that the particle size of the COVID-19 virus is around 0.1 µm (micrometer). In some jurisdictions, MERV 13 is a mandatory condition that must be met. �����Y,� � Framingham, MA – Over one weekend, the BAS team installed a new 172 ton Seasons 4 roof top unit (RTU). stream
If you have any questions about the proper level of filtration for you HVAC system please reach out to BAS. COVID-19 has presented numerous safety challenges to facility operations that has resulted in ânew normalâ best practices. It is an acronym for "high efficiency particulate … A simple, yet effective way to improve building indoor air quality is through the application of Ultraviolet Germicidal Irradiation (UVGI). Even if the virus is captured, it would likely survive for some time. However, many smaller rooftop HVAC systems are configured to hold only 2-inch depth air filters… Current guidelines from the Centers for Disease Control (CDC) and American Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) have some general recommendations in place. Air Filter MERV Rating. Second, if faced with a MERV-13 regulatory mandate and budgetary concerns that prevent the first choice, then 2-inch MERV-13 (not MERV-13A) air filters could be sourced, but be aware that the actual performance of MERV 13 air filters will be closer to MERV-8 after a period of time. Filter performance is measured by the fraction of particles removed from air passing through a filter and is represented by a MERV rating (Minimum Efficiency Reporting Value). 2. :���r_hځ�g�~�傼QS�?T��B
��zM�� What is recommended now by the standard setting body for HVAC is a MERV 13 filter." High Efficiency Particulate Air or HEPA filters outclass even the MERV 16 filter rating. MERV 14 Air Filters. We do not have enough information to confirm that a MERV 15 will remove coronavirus. Go beyond filtration. An air filter’s MERV rating is a scale from 1-16 that describes the minimum efficiency of the air filter. ���� JFIF ` ` �� ZExif MM * J Q Q �Q � �� ���� C ASHRAE is currently recommending operators use a filter with a Minimum Efficiency Reporting Value (MERV) of 13, but a MERV 14 (or better) is more preferable. <>
