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.

When my electronic filter stopped working I replaced the electronic filter with a 4" Filtrete and it worked great.

I've been using The Healthy Living A/C filters for 12 years now. They really help clean the air in my house!!!

This filter has some many things it can do for a more healthier environment, not to mention the air quality it provides by the features it possesses.

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

I have been using this filter with my carrier furnace/AC for the past 10 years. It works well for me

Started buying these years ago during allergy season, I know use them year-round to have great quality indoor air with much less sneezing.

I've used this filter for the last 6 months and it's really made a difference in air quality. Highly recommend if you have an indoor pet.

First time buying this particular filter and it was well worth the cost. I feel much better and the nasal stuffiness is gone. Thanks!
