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.
