Review on Nordic Pure Pleated Air Filter 18x30x1 - MERV 12 - 6 Pack by Mike Carter

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 and more surface area for air to flow through.
