Carrier & Bryant Cold Catalyst Filter for MAQB24-321 - 2 Pack

This genuine upgrade filter adds odor-neutralizing performance to select Carrier and Bryant ductless indoor units. Featuring cold catalyst technology, it helps reduce VOCs and household odors for a fresher indoor environment.

Compatible Indoor Unit Models:

• MAQB24-321
• MAQB12B-301

Filter Dimensions: 8-3/8" x 2"
Frame: Not included – designed to be inserted into your existing screen filter frame

Maintenance & Care

Vacuum the filter every two weeks using a soft-bristle brush attachment. Do not wash or rinse with water, as moisture will degrade the cold catalyst material and reduce its effectiveness.

Replacement Guidance

For best results, replace the filter every 6 months. The carbon-based catalyst layer gradually loses its odor-reducing power and cannot be refreshed through cleaning.
