🌬️ Nordic Pure 24x24x1 Pleated Air Filter - MERV 12 Efficiency, 6-Pack Review

Seems ok. I wanted something better than a Merv 4 MPR 300 dust filter, but not a Merv 10-11-12 filter clogged by a system fan. I can see it reducing airflow more than a dust filter. However, this is the middle ground I was looking for. A potential issue is the smaller standard 24" x 24" size of this filter. It's easily 3/8 inch smaller than the 3M filter filters I've used. This doesn't fit directly into the air return register and I put a 1/4" foam gasket around the register opening to make it…

These filters are not marked anywhere. I thought I would buy Merv 12 filters which is definitely NOT the case. The size was good for our 24x24 return. The filter is almost transparent. I tried to get filters easier by having them delivered. Nowhere on the packaging or filters is it marked as Merv12. Indeed there is a place to write, and it is empty. I compared them to two of our other filters, one from 3M and the other from Home Depot's Honeywell. You cannot see light through our other filters…

Filters mate with standard MERV pleated filters. Purchased size 24 x 24 x 1 inch The problem was that the size is not correct. Despite being square we rotated the filter on all 4 sides to make sure it wasn't facing the right way (or side) and there was no difference. They are undersized on all sides, probably 1/" - 5/8" less. It was inconvenient to fiddle around with and some sort of cardboard backing was required to keep the filter from being sucked into the pursuit and serving no purpose. No,
