Aprilaire® #413 Filter Media Replacement

This filter is used for Aprilaire® Models 2140 and 2400, provided the upgrade kit has been installed. This replacement filter can also be used for the Models 2410 and 4400 Aprilaire air cleaners. The filter is the heart of the air cleaner and needs to be replaced once a year or when your Air Cleaner Control indicates it is time to change the filter.
