The 10 Best In Duct Air Purifiers
This wiki has been updated 7 times since it was first published in January of 2019. 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 recommendations, we may earn commissions to help fund the Wiki.

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.
