I’m not really sure if I’d call it useless but hell idk..the filter gets nasty as fuck every now and then and needs replacing so it must be doing something. Anytime I clean my PC on the opposite side of the room it usually kicks on so maybe it is working pretty well. I bought it for back when I smoked cigs up here years ago but don’t anymore.

This “odor” light has been at least a couple years
