I bought a MERV 12 but a recent HVAC test showed it was too much for my system (reduced airflow) so I'm rejecting my next one Order by MERV 10 onwards. I like +Carbon because my air return is next to a bathtub with a litter box. The filters are actually a little tight, but I manage to get them in there. I'm very glad I found this brand a few years ago.
