The Aprilaire 413 DFS Replacement Filter is a MERV 16 whole-house air filter designed as a compatible replacement for Aprilaire Model 413 media. It fits Aprilaire whole-house air purifier models 1410, 1610, 2410, 2416, 3410, 4400, and Space-Gard 2400. The deep-pleated design provides a large surface area for maximum dust-holding capacity and optimal airflow through your HVAC system.

Rated MERV 16, the Aprilaire 413 DFS replacement filter captures up to 99% of airborne particles down to 0.3 microns. This includes fine dust, pollen, pet dander, mold spores, smoke, smog, bacteria, virus-carrying particles, and other microscopic allergens. Its high-efficiency media makes it one of the most effective whole-home filter options for households with allergy or asthma concerns.

The Aprilaire 413 DFS Replacement Filter should be replaced every 12 months under normal residential conditions. Homes with pets, smokers, high dust levels, new construction, or residents with respiratory sensitivities may require replacement every 6–9 months. Regular annual replacement maintains peak MERV 16 filtration performance and protects your HVAC system from particulate buildup.

The Aprilaire 413 DFS Replacement Filter measures 16" x 25" x 4" (actual size approximately 16 x 25 x 4 inches). It is specifically engineered to slide into the Aprilaire 413 filter cabinet without modifications. Always verify your existing filter model number and cabinet size before ordering to ensure a proper fit.

The Aprilaire 413 DFS filter sold at Discount Filter Store is a high-quality compatible replacement, not an OEM Aprilaire-branded product. It is engineered to meet or exceed the MERV 16 performance specifications of the original Aprilaire 413, delivering the same 0.3-micron particle capture efficiency and 12-month service life at a lower price point. It fits all Aprilaire air cleaner cabinets designed for the 413 filter.
