This filtering system is wonderful for our basement. We have two plant tables in the winter that are over 6' long, and the Filtrete really clears the air!

[This review was collected as part of a promotion.] I have been using Filtrete filters for 20+ years. I feel that they work extremely well to reduce the dust and allergens in my home. I replace them every 3 months as suggested.

I change our filters quite often due to dust and allergens that get circulated in our home. I find out filters last 2 months but I change them after 1 month. I’m going to the highest level filter shortly.

The 3M 4" Filtrete Filter is a quality product. It calls for a change every 6 months to a year. It does pick up quite a bit of traffic after 6 months, so we change it. The only issue is the cost. I guess you pay for what you get.

I've tried a lot of different filter makers. The Allergen Defense 1200 made a HUGE difference in just 6 hours after I installed it. My headache went away and the nasal drip stopped! I'm a true believer in my improved health!

This is the only product I purchase for our furnace. I particularly like that it only requires changing once a year. When we changed ours for 2024 we discovered that it could have remained in place longer.

Having the doors and windows closed during the cold winter months, I needed to find something to contain odors and bacteria to keep the air fresh and circulating properly. Glad I spend the extra few dollars on this great filter.

I've been using the Filtrete Healthy Living Air Filters for many years now and have been extremely happy with the results. Having 2 dogs, this filter catches a lot of the extra "fluff" in the air.

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.

[This review was collected as part of a promotion.] I've been using these filters for several yrs and they are great. I originally bought them because my son has asthma.
