This pack includes two 20x20x4 filters to support ongoing air quality improvements as air cycles through your system.
What it traps and how it helps
The 313 filter targets a broad range of common airborne triggers as air passes through its deep filtration media. While not a medical claim, many homeowners notice less dust and fewer visible particles on surfaces when filtration is in place.

- Nominal size 20 x 20 x 4 inches for easy replacement matching
- Genuine Aprilaire filter made in the USA with the Pure Fit Promise for exact fit
