Features:
1. 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
2. FOR OPTIMAL PERFORMANCE of your heating & cooling system or HVAC system, change your home air filter at least every 90 days for 1 in. filters
