20x20x1 AC Furnace Air Filter MPR 300 Clean Living Basic Dust 6 Pack

Outperforms fiberglass, washable, and static-free 3-month pleated 1-inch air filter for your furnace, air conditioner, or HVAC system.
Designed with 3-in-1 technology to trap unwanted air particles while letting cleaner air flow through.
Attracts and traps large particles such as lint, household dust and dust mite debris.
MPR 300 is rated at MERV 5.
The higher the MPR, the more particulates – such as pollen, pet dander, and smoke – your filter will capture from the air passing through it.
