The Carrier GAPCCCAR2420 Air Purifier Filter is a genuine OEM factory replacement air filter for the Carrier Infinity Air Purifier, Bryant Perfect Air Purifier, as well as other compatible air purifiers made by BDP, Payne, Day and Night Infinity, and Totaline (models GAPAAXBB2420, GAPABXCC2420, GAPABXBB2420, and other compatible units). It is also a compatible replacement for the Bryant GAPCBBAR2420 filter and other related air filters with nominal dimensions of 21" x 24" x 3.5" (actual dimensions: 21 5/8" x 24 1/4" x X 3 1/2"). Note that depending on specific supply received this filter may ship to you as either a Carrier filter or a Bryant filter though both filters are identical in size and effectiveness.
While many Carrier air purifier filters only feature a MERV 8 rating, the Carrier GAPCCCAR2420 air filter replacement has a MERV 15 rating and will reduce much more pollen, dust, pet dander, hair, dust mites, viruses, bacteria, mold spores, and other allergens from your indoor air than filters with lower MERV ratings.
This filter should be changed about once a year under standard conditions or more often under severe air conditions.
