I should probably check my filters at some point soon. My model offers the "replaceable" filters and rewashable filters... I immediately, at once decided we would be going with the "rewashable" filters. They may be lower quality, but my air filter seems to do a decent job in my vape area most of the time.... Now, if I could just get the husband to close the other doors like I have asked, LOL, I think most of my "fog" problems would be solved....
