[This review was collected as part of a promotion.] I've been buying this filter for a long time now because it works so well. My wife has allergy issues, but this filter makes her life normal.

I need a 18x20x1 1900 filter but Filtrete doesn't make one, settled for a 1500 but not satisfied. Found an Aerostar filter and an evaluating it, but would prefer Filterate for good quality control and honest rating assessment.

We have been using the Allergen Defense filter for over a year and I have noticed a dramatic reduction is the particals of dust in our house. That means less time I have to devote to dusting the floors and furniture.

We have used these over the past four years. Have allergies and noticed the difference once we started using filtrate. Just wish they sold them in a 6 pkg. We bought the 20x30x1.

I have used the Filtrete air filters for many years. They have definitely helped with allergies in our home. I can actually tell from how fresh the air is when it is time to replace.

I usually have used these in the past and recently purchased a different brand. I prefer these. They are better constructed and appear to better clear the air.

My 16"X25"X5" filter was 4 7/8 thick. It was about 1/2" too thick for my particular venting. Be sure to measure your filter box before ordering...........

[This review was collected as part of a promotion.] My husband bought another brand last time and is there ever a difference in performance. Not even close. Back to Filtrete Purple!

The Filtrete products are the best 4 inch filter I've ever used. Would recommend it to anyone else not happy with their current product. Less dusting is always appreciated. My allergies are thankful too.
