12v air purifier

[backwoods]

I'm searching for a 12v powered air purifier for under 300 sq ft. that does not emit ozone.
I am not having much luck finding such a thing except for the small usb powered ones.
Does anyone know if they make such a thing and if so could you link it?
Was trying to find one that used a power supply but came up empty with that as well.
Everything I've seen so far has been direct wired 120v. Or if they are battery powered, they emit ozone.

Here's an approach to consider. 5 or 6 years ago, I cobbled together a 12v air purifier using plywood, a "Fan-Tastic Vent 01100WH Endless Breeze 12V Fan", and a 120VAC Honeywell air purifier after the motor died (large circular cake tin style). We run it next to a wood stove in winter. The body of the air purifier (motor removed) just holds the air filter mesh now. It's not fancy, but it works great. Good luck in your search.
