These work great, you just have to be sure to replace them every 2-3 months because they do collect a lot of dust. My HVAC service tech said they were the perfect thing for good air flow + dust removal. He said that the higher MERV filters can really restrict airflow and cause strain on the system. These give great airflow while really catching a lot of dust. Of course, higher MERV filters will catch more, but I'd rather keep the air flowing and not have to replace the blower motor.

I purchased 12 filters (one per month) and they filter very well. Changed out one filter and examined how well it filtered the dust/pollen/etc. and it did a very good job catching all the debris. Will purchase again next year. And they are a great price.

I manage a lot of properties. I've been using this brand air filter almost exclusively for some time on 25-30 HVAC systems. I recently ordered 2 boxes of 6 of the 24x24 (23 3-8 x 23 3-8). In one box, the filters were 23 x 23.25; in the other, they were 23x23. That leaves a big gap for unfiltered air and dust to come through the return and into the system. Not happy at all; don't have time or interest to return. I'll use them begrudgingly, but I probably wont return to Nordic Pure again. I would have given them 5 stars prior to my noticing the mis-sizing, and it makes me wonder if this has always been an issue.

buying in bulk was great. works great. lasts a long time. I probably can get 5-6 months of use per one in my house. I own 2 outside dogs that come in daily. these just work. Merv 8 ratings seem to be the sweet spot with not hurting airflow and collecting the stuff that gets to the HVAC.

I ordered a pack of these, and when I went to use the first one, I noticed it didn't fit as well as the one I'm replacing (which was 23 7/8 inch square). This one is narrower by a half-inch in both dimensions (23 3/8 inch square), so I have to position it carefully or else one side of it will get sucked through the hole. Even so, there's a gap at the top of the filter. When I purchased it I didn't notice that the dimensions were smaller.
