MA-15 Filter Design

PRODUCT UPDATE:

Update as of 15 MAY 2025

From Hank: 

Similar to the MA-25 filters, the metal support on the back was removed and the carbon layer was changed. If customers will ask why the metal support/grills on the back (supporting the carbon layer) was removed, is to maximize the airflow performance. Assure them that the quality of the filters are still the same, with just a different design. Attached are sample photos of the MA-15 filters that a customer received.
