[This review was collected as part of a promotion.] Best filter I've ever bought! This filter is worth the extra $. I notice less dust/particles in the house and when I change it, I can see it is picking up more than other filters.

I have brought several of these filters after Katina we had a lot of dust in our home from replacing the sheetrock and these filters have made a big difference.

This Filtrete filter was recommended by my hvac installer and it’s worked great for me. I tried a cheaper brand and my allergies seemed to be noticeably worse. I only with they made the 20X25X4 in the smart option.

I used to try and save money on filters until I bought Filtrete. These filters are fantastic. I can see the difference and don't mind spending more for these great filters.

I have used these filters since I've owned my home for 4 years. You can definitely tell they work! Barely any dust around my house and when I go to change it every 3 months it's definitely dirty!

I have a whole house system and this filter is what fits the system. I have noticed that the dust in the house is way less than when I was using the metal filter that came with the system. I recommend Filtrete filters to all my family and friends.

We use to buy the "cheap" drug store air filters and thought they were doing a decent job of filtering. Since we changed to Filtretes our house is cleaner and my furnace internals stay cleaner.

We have been using these for years, living in Florida and believe that these filters keep down the amount of pollen from outside and dander from our 2 dogs inside.

I bought the 4" filter for my heat pump and it is working great. No loss of air flow and is removing the dust from the air. Will buy another one when it needs replaced.

[Employee of 3m-filtrete] I am fairly diligent in changing the air filter in pur home. The amount of dust that is filtered out of the air is amazing. Thanks for this great product.
