Filtrete 9807-4 Air Filter, 20 in L, 10 in W, 11 MERV, 1000 MPR, Polypropylene Frame PACK OF: 4

Opt for a Filtrete™ allergen defense air filter to transform your central heating and cooling system into a whole-home air filtration operation. This no-nonsense filter helps capture varying sizes of particles, from the large (lint, pollen, dust and pet dander) to the microscopic (smoke and smog).

Features

• Outperforms fiberglass
• Designed with exclusive filtrate brand 3-in-1 technology from 3M to trap unwanted air particles while letting cleaner airflow through
• Attracts and captures particles such as lint, pollen, dust, pet dander, smoke and smog
• The higher the MPR, the more micro particles such as pollen, pet dander and smoke - your filter will capture from the air passing through it
• For optimal performance of your heating and cooling system or HVAC system, change your home air filter at least every 90 days for 1 in 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
