Review on Nordic Pure 20X30X1M13 6 20X30X1 Pleated by Bob Fasho

I bought this filter as an upgrade to the Nordic Pure MERV 12 that I had for my previous box and to be honest, I didn't notice much of the difference. The filters are true to size and I've never had any issues with them, but as I move up the MERV department I'd like to increase the filter capacity, but I haven't noticed that. It's still a quality filter though, and even with three dogs and living in a dusty area, I only have to change them once a month at the moment.
