Aprilaire #413 Expandable Media

These are the original, OEM expandable "accordion" style, factory recommended replacement filters for the Aprilaire Model 4400 / 2410 Air Cleaner. 
 
The filters ship like a collapsed accordion and are expanded into a frame within the air cleaner cabinet.

The air cleaner media in the Model 4400/ 2410 can last from a few months up to 1 year. It may be necessary to change the media more frequently, in the presence of a 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 every month for cleanliness.
