Bought these filtered because the other cheaper brands weren’t doing the job very well. These work much better at catching more dust.

Used this brand for years. The size I need 20x30x1 is difficult to find so when found I snap them up!

Just started using this product. Too early to tell how it’s working. Not sure I will be able to tell if it works any better or worse than the last filters I used

It is a good filter, but I’ve been told now by three different air-conditioning companies that they are too hard on your air condition unit and it makes them work too hard and to go to a lower grade.

I'm unable to give a review at this time regarding quality or performance. I bought these because they were a good value and I expect they will perform great but until I use them I can't say with certainty.

I had to pull this and put in a temporary fiberglass filter after 1 week. The airflow to the farthest rooms was poor and the rooms got too cold. The pleating looked good and the filter isn't visibly dirty. I'll stick with the Merv 7 filters.

[This review was collected as part of a promotion.] These filters are really nice quality. They are slightly thinner than the ones we have been using for years, but I feel they do a nice job. There’s less dust throughout the house with these. They were super simple to install. No problems!

I have three 20/20/1 and one 20/30/1. Use other brands no problem with the fit on the 20/30/1. I JUST SPENT HALF HOUR BENDING THE 30/20/1 to fit. Bought 4 packs year supply. Every three month I fight with the 20/30/1. The 20/20/1 fit with no issues. This is the last set for the year. Last year I should had Bought a different brand on the 20/30/1. Cause this will be the third year that I have purchased thrse. I will continue to buy the 20/20/1. I hope the company will fix the dize to fit Thank ypu

We started buying the Filtrete 1600 Ultra Allergen because we live in an area that produces lots of pollens, and we have a dog. We can definitely see and feel the difference with using this brand series and other brands. We sneeze less, and there's less dust. Our home has a fresh smell and does not smell dusty like some other places I have been. To make things even better, they are cost efficient. I won't ever change filters as long as these are available.

[This review was collected as part of a promotion.] 3M Filtrete Ultra Allergen Bacteria and Virus air filter makes the air in the house feel and smell cleaner. I feel comforted that the filter removes bacteria and viruses. Built well and easy to install.
