I love the idea of cleaner air, but my furnace company told me I needed to change the setting on my furnace when I use a higher quality filter such as this one. This was unexpected news.

I had my doubts when I bought this filter but after just a few days we can tell a difference its making in our home. The air is fresher, cleaner and our babies are having less allergy problems. I love this product and will continue to purchase them.

I love things that just work. You know; Do exactly what they're supposed to do. These filters do that. In the country, one cat, and clean fresh air. Not to mention clean and efficient work load for the central heat and AC unit. Thanks Filtrete

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.

I have asthma and allergies. I have used Filtrete for many years. There is a noticeable difference in air quality while in use. Just wish they were a little less expensive.

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,

This filter removes all of the smells we've gone nose blind to over time. The other day I cooked some fresh fish and ran out for an errand. When I came back I could not tell what we had for dinner. Can't say the same at my neighbor's house!

I know this filter works because when I change it, within the 90 day recommended time, with its fine filter capabilities, it really does its job as the filter is grey with particles.

Our house is more than a century old (built in 1888). Dust particles were magnified in the light that streamed through the over-sized windows. Filtrete filters have given us new appreciation for floor to ceiling sunlight.

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!
