AprilAire #401 Filter Replacement Media

 #401 Media for Aprilaire/Space-Gard Models 2400 Air Cleaners

These are the original, OEM expandable "accordian" style, factory recommended replacement filters for the Aprilaire/Space-Gard Model 2400 Air Cleaner. 
 
The filters ship like a collapsed accordian and are expanded into a plastic frame within the air cleaner cabinet. The filter is installed within the plastic frame and held in place with your existing pleat spacers(NOT INCLUDED).

Assembly instructions are printed on the product carton.

The air cleaner media in the Model 2400 can last from a few months up to 1 year. It may be necessary to change the media more frequently, in the presence of high concentration of dust and/or particulates, or if the furnace fan is running continuously.

In any application, the life of the media is dependant upon the total volume of air being moved through it as well as the amount of particulate it is filtering. Inspect your air filter on a monthly basis for cleanliness.


Filters are expanded into existing plastic frame and held in place with existing pleat spacers
