I change my filter that every two months. Every time I change my filter with this product I see the nastiness it keeps my family from breathing in. I wouldn't trust any other brand!

My 16"X25"X5" filter was 4 7/8 thick. It was about 1/2" too thick for my particular venting. Be sure to measure your filter box before ordering...........

I used to try and save money on filters until I bought Filtrete. These filters are fantastic. I can see the difference and don't mind spending more for these great filters.

Having the doors and windows closed during the cold winter months, I needed to find something to contain odors and bacteria to keep the air fresh and circulating properly. Glad I spend the extra few dollars on this great filter.

I've used various filters and found this model to be very effective. Amazed at what it actually catches from the normal air. Noticeably helps during the allergy seasons (severe hayfever).

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.
