Aprilaire 501 Replacement Filter ¨C 4 Pack

This is Genuine Aprilaire / Space-Gard replacement filter media for their Model 5000 media air cleaners. The Aprilaire brand of replacement media is the best to use for both Aprilaire and Space-Gard Media Air Cleaners. For many years Aprilaire sold their media air cleaners under the Space-Gard brand name. Now they use the Aprilaire brand name. The filter media used in the Model 501 is made of bonded glass micro-fibers. The MERV rating for this product has not been determined. The test required to determine a MERV rating for an air cleaner specifies the use of a special dust that has the result of reducing the performance of all electronic air cleaners not just Aprilaire’s. For that reason Aprilaire was unable to determine the MERV rating of the Model 5000. The media will typically last one year. If installed on a 5-ton system or in the presence of high concentration of particulate it may need to be changed more frequently. Get the Performance You Deserve.
