3M Filtrete Micro Allergen Filter - 22x22x1 - 6-Pack

The Filtrete Micro Allergen filter offers very high performance at a very reasonable price - and is probably the best bang-for-the-buck in disposable furnace filters. It removes allergens like Pollen, Mold Spores, Dust Mite Debris, Household Dust, Lint, Smoke, Pet Dander, and Smog. Like all 3M Filtrete filters, the Micro Allergen filter lasts for 3 months, and is electrostatically charged, which helps it to attract even the smallest particles without restricting the airflow in your system.
