20 x 25 x 4 Air Filter Replacements
20x25x4 is one of the most common 4-inch media cabinet sizes. This collection carries Tier1 filters in three MERV levels, all sold in 6-packs:
- MERV 8: captures everyday dust, lint, and pollen. A solid standard choice for most homes.
- MERV 11: adds finer particles like pet dander, mold spores, and some bacteria.
- MERV 13: the highest of the three, capturing smoke and virus-sized particles. Recommended for allergy sufferers.
Higher MERV ratings restrict airflow slightly more, so if your system already struggles with airflow, MERV 8 or 11 is the safer pick. A 4-inch filter typically lasts 6–12 months.
