Filtrete 12x12x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

These fit perfectly, did a wonderful job filtering / cleaning up all the strands of fur coming from my cats being sucked into my duct work! Cant imagine the mess Id have with a lesser filter. Ive been using these for several years and have been very happy.

The 12x 20s are getting harder to find. This is a great brand and easy to swap

Very good product. No damage in shipping. I will be buying more

Great filter

I find the 1500 series of these filters to be the sweet spot for filtering out the air in our home these last us about a month and I change them out regularly. It only takes a side by side comparison between the one I took out and the one I put in to see just how much junk was in the air that these filters cleaned out before it got to us that is a priceless value to me and my family thank you

Traps so much dust, I should replace them every 2 month

When we had a new HVAC system installed last fall (2018), we decided to modify the sizes of several cold air returns, so that we could place a typically sized filter in each one. We have 2 dogs, and when my husband replaced all the ducts prior to having the new system installed, we were shocked by how much dust and dog hair was inside the old ones! These filters should prevent most of that build-up in the future. It’s going to be a bit expensive to replace so many filters every 1-2 months, but the advantage should be worth it.

Good quality, right size for what we needed which was to cut it into squares for use as a replacement for an air filter that is no longer getting custom fit inserts. The filter started working right away and we will definitely re-order these in the future. It is a little bit messy to cut them but the cardboard edges give it good rigidity for what we needed.

great

Very easy to install and good product.
