Keep your home free from dust and common airborne particles with the Aprilaire 310 replacement filter. This genuine, USA-made filter is designed to fit Aprilaire air purifiers models 1310, 2310, 3310, and 4300, and it arrives in a convenient two-pack. The nominal size of 20 x 20 x 4 inches reflects a larger filtration area that helps capture pollen, dust, mold spores, and other irritants as air passes through the filter.

This design supports longer intervals between filter changes compared with typical 1-inch options, reducing maintenance tasks and keeping your home cleaner over time.
