MERV(Minimum EfficiencyReporting Value)
Astandardusedtorate theeffectivenessofair filters.
Measureshowwellafilter capturesparticlesof differentsizes.
RatingEfficiency
HigherMERVratings indicateagreaterability tocapturesmaller particles.
RatingScale
Ratingsrangefrom1 (leastefficient)to20 (mostefficient).
Captures65%-80%ofparticles between1.0and3.0microns,and atleast50%ofparticlesbetween 0.3and1.0microns.
Efficiency
Providesagoodbalanceof filtrationefficiencyforcommon allergensanddust.
Frequentlyrecommendedfor residentialuse,balancingair qualityimprovementwith systemcompatibility.
