Merv Rating Chart Ashrae

Merv Rating Chart Ashrae - Web this standard uses a scale called the minimum efficiency reporting value (merv), which rates a filter's ability to capture particles on a scale of 1 to 16. 80% ≤ em < 90% m.e.: It also shows air filter efficiency levels. Web ashrae currently recommends using a minimum merv 13 filter, which is at least 85% efficient at capturing particles in 1 μm to 3 μm size range. Web merv values in the 52.2 test reporting. Web the rating is derived from a test method developed by the american society of heating, refrigerating, and air conditioning engineers (ashrae) [see www.ashrae.org]. A merv 14 filter is at least 90% efficient at capturing those same particles. The purpose of the merv system is to measure how well air filters trap particles of varying sizes, otherwise known as filter efficiency. Web minimum efficiency reporting values (merv) scaled rating of the effectiveness of air filters. Here’s where hepa (high efficiency particulate air) filters come in.
