I absolutely love using Filtrete filters. I choose the Healthy Living product because it does and takes care of it all. They work so well I do not even have to dust the furniture anymore. Filtrete is worth every penny and is a time saver to boot.

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.

Our HVAC was installed over 8 years ago. We change the filter every 6 months at during our spring/fall checkups. During a recent home inspection for our refinancing. The inspector asked did we recently change the airvents and ducts?

Over the years we have tried dozens of filter, since we switched to Filtrete we have not tried any others. This product works, we have cats, dog, and it keeps the air clear and fresh.

Even if you don't run or have a whole house fan unit buying the 12x12 is a great way to a cheap air filter. Just tape a 12x12 Filtrete onto the back of a box fan and you're good to go!

I have used this air filter in my home and it noticeably reduces the amount of allergens. Also amazing how much it picks up when it is time to replace. A great product.

the physical dimensions are > 4", actually close to about 4.5". Be sure you're housing will accommodate 4.5" before purchasing. Can't comment on the function because these would not fit.

My family has allergies to include to dust mites, etc. Using this filter has had a noticable difference in their health/feeling around the house. Thrilled that I got them and they keep the air nice and clean!

I've been using the Filtrete allergen filters for over 8 years in my forced air furnace/AC unit. I can breathe better and the house has reduced dust. It makes for easier cleaning!
