Healthy Living MPR1500 Merv12 Ultra Allergen Filters 12 By 20 By 1 Inch. OUTPERFORMS FIBERGLASS, WASHABLE AND NON-ELECTROSTATIC 3-month pleated 1 in. home air filters for your furnace, air conditioner or HVAC system. DESIGNED WITH EXCLUSIVE Filtrete™ Brand 3-in-1 technology from 3M to trap unwanted air particles while letting cleaner air flow through. ATTRACTS AND CAPTURES microscopic particles such as smoke, cough and sneeze debris, bacteria and viruses--and large particles, including lint, household dust and pollen. 1500 MPR has a rating of MERV 12. The higher the MPR, the more microparticles--such as pollen, pet dander, smoke, bacteria and viruses--your filter will capture from the air passing through it. 54% SMALL PARTICLE CAPTURE, like bacteria and particles that carry viruses* (* % captured is based on ASHRAE 52.2 testing for 0.3 to 1 micron particles from the air passing through the filter, which relates to HVAC industry standard efficiency testing). FOR OPTIMAL PERFORMANCE of your heating & cooling system or HVAC system, change your home air filter at least every 90 days for 1in. filters, and at least every 12 months for 4 in. and 5 in. filters. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool--wasting energy. FOR RESIDENTIAL use only.
