Capture a minimum of 20% of E2 Particles (1.0-3.0 microns) & minimum of 70% of E3 Particles (3.0-10.0 microns). They are also effective at removing most airborne particles that could cause allergies or asthma to flare up without putting too much strain on the HVAC air blower or compressor. MERV 8 filters trap particles sized 3 to 10 microns. MERV 8 filters are effective at trapping 90% of the airborne particles found in the average home. Recommend that MERV 8 filters be changed every 2-3 months to keep them running at full capacity. MERV 8 filters trap dust, lint, debris, pet hair, particles from sanding or spray painting, and textile fibers from clothes or carpets. MERV 8 filters work best in residential homes with average filtration needs. If you are worried about outdoor air pollution, family members with respiratory issues, or pets in the home, then going with a higher MERV rating might be a good idea.
