Universal Cut-to-Fit Design

The 3M FAPF-UCTFN-4 is a HEPA and activated carbon pre-filter designed for residential air purifiers. It targets common household odours from cooking, tobacco smoke and pets. The universal sheet measures 23.8 by 20.5 inches with a 0.2 inch height and can be trimmed to fit most room air purifiers.

Compatibility and Installation

This filter is confirmed compatible with Filtrete air purifier models FAP-C01BA-G1, FAP-C02WA-G2 and FAP-C03BA-G2. Builders using other brands must verify dimensions before cutting. The pre-filter sits upstream of the main HEPA filter, trapping larger particles and odours to extend the life of the primary media.

Maintenance and Lifespan

The manufacturer rates the filter for up to 6 months of residential use. Replacement timing depends on actual air quality and runtime. No power draw, noise or thermal output is generated by the passive media itself.

Questions about this item

How long before the carbon layer saturates and stops trapping odours?

The filter is rated to last up to 6 months before the activated carbon needs replacement.

Does the thin 0.2-inch frame restrict airflow or make the purifier louder after weeks of continuous running?

At only 0.2 inches thick the pre-filter adds negligible resistance, so fan noise and power draw stay essentially unchanged.

Which Filtrete purifier models accept this 23.8 by 20.5 inch sheet without trimming?

It fits the FAP-C01BA-G1, FAP-C02WA-G2 and FAP-C03BA-G2 units directly; other models require cutting to size.
