Par exemple, un filtre avec une cote MERV ad\u00E9quate peut remplacer un filtre HEPA couteux et parfois inappropri\u00E9 dans un syst\u00E8me central \u00E0 cause de la diminution de pression occasionn\u00E9e par la densit\u00E9 du filtre HEPA. Des \u00E9tudes ont d\u00E9montr\u00E9 qu'un filtre avec un MERV moyen de 7 \u00E0 13 est presque aussi efficace pour \u00E9liminer les allerg\u00E8nes qu'un filtre HEPA beaucoup plus couteux \u00E0 installer et \u00E0 entretenir."@fr . . .

"Minimum Efficiency Reporting Value, commonly known as MERV, is a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to report the effectiveness of air filters in more detail than other ratings. For example, often a HEPA filter is impractical in residential central HVAC systems due to the large pressure drop the dense filter material causes. Experiments indicate that less obstructive, medium-efficiency filters of MERV 7 to 13 are almost as effective as true HEPA filters at removing allergens within residential air handling units."@en . . . . . . . .

"Minimum Efficiency Reporting Value, commonly known as MERV, is a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to report the effectiveness of air filters in more detail than other ratings.

Experiments indicate that less obstructive, medium-efficiency filters of MERV 7 to 13 are almost as effective as true HEPA filters at removing allergens within residential air handling units. The scale is designed to represent the worst-case performance of a filter when dealing with particles in the range of 0.3 to 10 micrometers. The MERV value is from 1 to 20. Higher MERV values correspond to a greater percentage of particles captured on each pass, with a MERV 16 filter capturing more than 95% of particles over the full range. The table displayed below is a grouping of MERV values by particle size: While the lowest MERV value in each row has no minimum requirement for filtering the particle size for that row, it does have stricter requirements for all larger particle sizes than any lower MERV value. For example, MERV 13 has no minimum requirement for removing 0.3\u20131.0 \u03BCm particles (the standard specifies <75%) but has higher minimum requirements for removing 1.0\u20133.0 \u03BCm, 3.0\u201310.0 \u03BCm, and > 10 \u03BCm particles than MERV 12 and all lower MERV values. All other MERV values on each row do have minimum removal percentages for that row's particle size."@en .
