UV filtration system

How effective are these systems? It seems like they kill stuff but don’t actually filter the air. Am I right? Should they be installed in conjunction with another type of filter?


Thank you.

They are typically are used in conjunction with a filter.

Read the post again JJ…HVAC! Huh?

Oops… musta had water on the brain! :shock: My bad. (I will delete to avoid confusion). Thx.

Ok thanks Tom. I didn’t find a filter on the one yesterday.
