You can use ozone generators instead of UV. There is actually a really good residential one that is self cleaning my own HVAC guy recommended.

He recommended I buy it myself on amazon and linked me to a youtube to install it: https://www.iwaveair.com/products/iwave-r

He said that his company would install it, but they'd overcharge and it is easy for anyone to install themselves. He had one in his house and told me all about it like a sales pitch. I installed one not because of the coronavirus, but because it helps with particulates in the air such as pollen and dander, which absolutely wreck me. I've only had it for a year, but it does seem to be noticeably better allergy-wise.



That one specifically says it ionizes without creating ozone.

That's a good thing, because there is no safe/acceptable level of ozone in indoor air:

Ionizing can be a great way to remove fine particulate from the air, but it works best when there are charged surfaces for the charged particles to plate-out on. Simply ionizing them in the ductwork means the particles stick to whatever's handy, which may be the ducts, may be the furniture, may be your lungs.

Which is to say, this product uses a lot of the right vocabulary, to describe precisely the wrong engineering.


UVC also generates ozone as a byproduct but it's toxic and it damages the lungs.

Do read the warning from the EPA.
