I use these filters in the winter when the heater is running a lot but there are not really outdoor allergens getting in the house.

So much better than cheap filters. A 99-cent filter is a waste of money; save your 99 cents and use nothing or invest in a truly effective filter.

Happy with product, this level of filtration doe not seem to put a strain on my high efficiency furnace

Healthy Living filter does a high performance job of cleaning air in our home...Living in Arizona our A/C is on almost all summer.

I love this product. That's to my mother -in-law for turning me on to it. I don't use any other breand.

We have a relatively new construction and I'm always amazed at how dirty these get after a few months of use. That tells me they really work!

I get these because of my allergies. These really help. They don't make allergies go away but it sure does lessen the severity of the problems.

I just bought this today and I'm already breathing better. I have allergies bad and have pets this products is amazing
