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.

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.
