Atomic Compatible for Carrier PGAPXCAR1620 / AGAPXCAR1620 Air Purifier Cartridge Nominal size: 16x20x3 - Actual size 17.3x21.9x2.6

Great replacement

Pros: Great replacement at a lower cost. The fit is precise, the quality of the filter is very good, and the electrical contacts on the filter work well with my carrier electronic air cleaner system. Con: Wish the filter was available in a lower MERV rating as I do have slightly high static air pressure in my HVAC system.

So far so good! Just replaced this filter vs the Carrier OEM version. Appears to be working well. Will report back following longer term use.

Direct replacement for Carrier filter. Seems to work fine.
