20 x 20 x 1 Air Filters
Filtrete's 20x20x1 filters come in three tiers, and a higher number means finer filtration:
- 1000 Micro Allergen (about MERV 11): captures dust, pollen, pet dander, and other common allergens. A solid everyday choice.
- 1500 Ultra Allergen (about MERV 12): adds finer particle capture, including smoke and smog.
- 2200 Elite Allergen (about MERV 13): the most efficient of the three, capturing the smallest particles, including bacteria.
Higher tiers restrict airflow slightly more, so if your system already struggles with airflow, the 1000 is the safer pick. All three come in 4-packs; replace 1-inch filters about every 3 months.
