Exact Aprilaire / Space Gard replacement furnace filter media for Model 2400
Replaces Part #401
We sell only factory recommended, original "accordion style" filters.
Non-original filters may reduce the amount of air flow, causing overheating and system malfunctions. Protect your equipment and replace your filter before the heating/cooling seasons.
Note: Gard and Aprilaire are the same company. The filters used to be called Space Gard but adopted the Aprilaire brand some years ago.
