A high-MERV filter and an in-duct UV unit sound like they do the same job. They don’t — and the best setup uses both.

Side by side

MERV 13 filter In-duct UV (APCO-X)
Removes Dust, pollen, particles Mold, bacteria, odors, VOCs
Airflow impact Restricts airflow None
Treats the AC coil No Yes
Maintenance Swap every few months Lamp every ~3 years
What it can’t do Kill microbials or cut odors Catch large particles

They solve different problems

A filter is a net for particles. UV neutralizes the living and gaseous stuff a net can’t catch — mold on the coil, bacteria, odors, VOCs. Run a good filter and add UV; together they cover both.

Why the coil matters

UV keeps the cold, damp evaporator coil free of biofilm, which keeps airflow and efficiency up over the years.

Common questions

Should I use a filter or UV?
Use both. A filter catches particles; UV neutralizes mold, bacteria, odors, and VOCs that a filter can't.

Does in-duct UV restrict airflow?
No — unlike a high-MERV filter, the in-duct UV unit doesn't restrict airflow.

Does it ship nationwide?
Yes — the genuine Fresh-Aire UV unit ships nationwide with tracking.
