4" MERV13 Air Filters
4" MERV 13 Air Filters
MERV 13 is the highest filtration rating practical for most residential HVAC systems, capturing fine particles including smoke, bacteria, virus carriers, and ultrafine dust that lower-rated filters pass through. The 4" depth provides significantly more media than standard 1" filters, translating to longer service life — typically 6 to 12 months between changes.
We carry 4" MERV 13 filters in two formats:
Universal 6-packs in the most common residential sizes — 16x20x4, 16x25x4, 20x20x4, and 20x25x4 — stocking you for a full year or more at a time.
OEM cross-reference 2-packs sized at 19 x 20 x 4¼ inches, compatible with whole-home media systems from:
- Carrier (FILCCFNC0021)
- Bryant (FILBBFNC0021)
- BDP
- Totaline
- Payne
- Day & Night
If your furnace or air handler is one of these brands and takes a proprietary media cabinet filter, you're in the right place. These Tier1 replacements are engineered to match OEM dimensions and filtration performance at a lower price.
