Nordic Pure Pleated Air Filter 18x30x1 - MERV 12 - 6 Pack Review

Very happy with it. We have a treadmill in our living room which makes it smell a bit like the gym. Turning on the central fan and using the air purifier for an hour really helps. The box appeared to have been opened, but the air filters were unused except for one that was slightly worn and was inside the box upside down. I suspect someone tried it, didn't work and returned it. It wasn't a problem for me. Sits tight and works great!

I have read a million articles and wanted to buy the best filter as my son is allergic to dust. Most of the information I found said anything above merv 10 is considered commercial grade and a typical home unit may not let enough air through, reducing efficiency and increasing running costs. So we opted for Merv 10, the highest apartment complex which seemed to get good reviews and was a good price. We're happy with it so far, but have only used 2.

I was happy to find filters that fit our unit as it is a unique size and that I can get better quality filters at a lower price than the ones I usually find it in the store. After reading some of the other comments, I checked the Merv rating on my packaging and the filter information to make sure I had the right product, which I did. These are the longest lasting filters I have ever bought. I really like that they have an accordion structure to have more surface area to catch dust and particles
