[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.

With 3 dogs, 2 cats, kids and husband, I need all the filtering I can get. I notice when I forget to change it. Air conditioning was boggind down. Bill seems more.

Am very satisfied with the effectiveness of the Filtrete 16x25x4 filter. I have a variable speed fan on my HVAC unit, and run it 24 hrs. 365 days. My house stays fairly dust-free. I am happy to let the filter do the work for me!

Space between rails in Lennox furnace for their 5” filter is only 4 7/16”. The filtrete 5” filter is 4 11/16” thick. Going to try filtrete 4” filter that is 4.31” thick.

I've been using these products for over 10 years. I will search out stores that carry them and have been pleased with the increased efficiency levels the company keeps producing.

I purchase the normally 3M 1000 'red color' wrapped filter that I used quarterly. I think it works wonderfully. It is the best product for me for my house, quality wise and price wise.

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 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.

[This review was collected as part of a promotion.] My go to ! Super easy to put in, best preforming and doesn't fall apart! Works well with our unit! Makes our maintenance super easy my 8 years can do it !

I purchase one of your other filters and seen that it did not preform as well, when I purchase the Healthy living filter, I saw a big difference, my wife were able to sleep better at night and there was less dust on top of my frig,
