[This review was collected as part of a promotion.] This filter has made all the difference because I have noticed that I don’t have to dust as much when I have this brand filter. I am also noticing less asthma attacks.

[This review was collected as part of a promotion.] This Filtrete Ultra Allergen air filter works great from what I can tell! It seems like my families allergy attacks have dropped quite a bit. Also, no colds or flu thi season either!

I noticed how well the filters were made when I had to trim them to fit my return. Can you please stock 12x30x1 so I don't have to cut off two inches from the 14?

[This review was collected as part of a promotion.] I use 3M Filters. I like the quality of 3M products and I prefer their filters as well. I feel like it traps more than others.

Disappointed. I just went to change the filter which was clean. Was in for 5 Months. Looked like it was in for a week. Problem is the filter is deteriorating. My wife has been complaining of white dust and now I know why. The filter is breaking down at the folds. I always thought of 3M products as the best and that's why you pay a premium for them. Have to rethink that.

Just got these delivered and they are not the size I ordered.

Ihave used Filtrate air filters for a number of years. The equivalent of MERV 12 are just perfect

I always buy these from Sam’s & I’m very happy with their performance!! Highly recommend these furnace filters!!

[This review was collected as part of a promotion.] This air filter is a definite recommend! Perfect and better air.
