The Aprilaire 413 (2-Pack) replacement filter provides MERV 13 particulate filtration performance without the need for installing pleat spacers like the old Space-Gard 201/401 media. The Aprilaire 413 filter simply pops up to the proper size and slides directly into several of the Aprilaire filter cabinets.

You will need to change this filter about twice a year.

This new style filter media DOES NOT require the use of pleat spacers but DOES require you to have purchased the 1413 Upgrade Kit in order to install it in a model 2400 or 4400 air cleaner.
