Had to use non Filtrete brand purchased at local hardware store when our Walmart was out of sizes we needed in every filtrete and that reiterated what a superior product Filtrete makes. After just two weeks of the other brand dust was more Prevalent in the house in spite of air purifiers We noticed a dusty odor by week two which reminded us to check the filters. And we immediately went to purchase these and make sure we keep plenty in this level and the two above it at all times for both units in our home

Great product
[This review was collected as part of a promotion.] I got this from 3M to try it out . I love it easy to put in and easy to get the app. No more taking the filter out and see if they need changing all you have to do is go to the app on the phone and see when you put them in and see the filter life.And also love all the particles that it removes

Bring back charcoal filters
These are pretty good but I prefer the ones with charcoal. I can't seem to find them anymore!

Check exact measurement of air filter
The 3M Filtrete 18x24x1 air filter is bigger than the air filter I needed to replace; therefore, it could not fit in the wall air conditioner.
