Best High-End
Best Mid-Range
Best Inexpensive

We spent 24 hours on research, videography, and editing, to review the top selections for this wiki. These in-duct purifiers use powerful UV lights and/or other methods to keep mold, bacteria, and other harmful particles out of the air you breathe. The science is out on how effective they are, though, and you should leave the installation to the pros, as even brief exposure to a UV lamp can cause eye or skin damage. We did not include any that produce ozone, as that can be dangerous. When users buy our independently chosen editorial picks, we may earn commissions to support our work.

Editor's Notes

February 25, 2019:

Buyers who are concerned about the radiation these machines produce can sidestep the issue entirely by purchasing the RGF Reme Halo, which doesn't use any radiation. However, as we mentioned above, while that unit can certainly make your whole home smell better, we're not sure whether it's any more effective at killing germs than the lamps on this list. Any model that's installed near the coils, such as the Reko Lighting Pureuv or the Apco Whole House, can also provide peace of mind, as there's much less chance of any accidental interaction with the lights.

After getting his bachelor’s from the University of Texas, Quincy Miller moved out to Los Angeles, where he soon found work as a copywriter and researcher, specializing in health and wellness topics for a major online media brand. Quincy is also knowledgeable about home improvement, as he’s had extensive experience with everything from insulation to power tools to emergency room trips, sometimes in that order. Sharing a home with three dogs and a couple of cats has forced Quincy to learn as much as he can about pet supplies, animal nutrition and, most importantly, the best ways to tackle the mountains of fur that accumulate in every corner of your home.
