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

When I was ordering, I needed 20X25X1 ---that is what I had searched for and that is what I clicked on. Since I needed 4 of them, I selected a 4 pack. What I didnt realize was that when I clicked on 4 pack, the size changed and when I received the order, I got 20X30 X1. Of course I had to return those since they were too big-----and then I was charged for shipping, so there wasnt enough money to order the correct size. I ended up going to a local store and finding something that would work. I tried the order again (not ordering, just seeing if that would happen again) and when I clicked on a 4 pack or other bundle, sure enough, the size changed. So, just beware that could happen and check and check again to make sure you are ordering the right thing.

I have four animals in my house and these made a HUGE difference in my allergies. Two cats and two dogs (if I dont sweep twice a week it looks like a furry animal was mauled across my house, thats how much hair sheds off my animals). I often have to vacuum the pet hair off the intake and sometimes off the filter because it gets covered so quickly, but it works very well and again, is a huge help with allergies.

Great buy easy to install and love buying in bulk

Fit perfectly and Im not sneezing my head off every morning

Very happy with this purchase. We will definitely be re-ordering.

Fits perfectly and appears to filter well. Good price too.

I believe my previous order from Amazon were counterfeit filters. They were not the same quality. Also the box was damaged in shipping. This was a much better experience and the price is on par with local stores. They were double-boxed and arrive in great shape. Unfortunately, stock is always low. Make sure yours is a genuine 3M when it arrives.

Expensive

I have tried several of the alternate lower cost brands and they often do not fit correctly. The last off brand ones were so small about 1/2” too small and wouldn’t stay In the holder so we’re unusable. These fit perfectly. They cost a little more but they do fit!

Good
