Review on π¬οΈ Nordic Pure 20x30x1 MERV 14 Pleated Furnace Filter by Andy Hearshman
Seems like a lot.
These filters are a great deal but I'm a bit concerned about Merv's rating. I replaced my Merv13 with these Merv14s, but the old filters had at least twice as many pleats as these. From what I've read, one of the main differences in the Merv ratings is the crease density, so I'm wondering why.
