Our main air return is 20x40 so the only filters that work are two 20x20's. I was tired of paying almost forty dollars for the Filtrete filters each time I had to change them so when I saw a set of 6 for less than the Filtrete's I was anxious to try them.
Although the composition of the filter material itself is different than the Filtrete's they seem to be the same quality. The thickness of the filter is about the same. It seems like it would do a really good job keeping dust and allergens from getting through.
It says these should last 60-90 days - and while that amount of time hasn't passed yet they do look much better than the ones I bought at Home Depot that only lasted 45 days.
These fit well and have the arrows to let you know which way to put them in. Overall I am very pleased and will continue to buy these in the future.
I hope you found this review helpful and feel free to ask any questions below by clicking on comment and I will try to answer as quickly as possible.
I received this product at a discount or for free to try and was asked (but not required) to give an honest, unbiased, and fair review. I rely on reviews just as much as you do and detest fake five star reviews. This review is based on my actual use of the product and I will always point out any negative things I can because I believe in fair reviews. If my opinion changes over time with use of the product I will come back and give an update to this review.
