Whole Home In-Duct Air Purifier

[CigarNut]

Anyone havre any experience with these — our A/C maintenance company sent us an advertisement (https://www.rgf.com/products/air/halo-led-whole-home-in-duct-air-purifier/).

Just wondering whether these actually do anything worth having.

My father-in-law has one and he says it's made a noticeable difference with his allergies.
