I purchased the Filtrete 90 day filters while an instant value and received a one year supply for $6 off the regular price. I trust these filters to keep my furnace and A/C operating at good performance.

These filters are bodacious! I breathe better than ever now. I can feel the air pumping through. Clean, fresh, delightful and pure! Other air filters are not as good. These are best that can be!

Filters Are great. We have 3 cats that adopted us and a lab my son adopted to us and these filters handle the hair and dander just fine . Not to mention they’re better value than the merv 11 I was gettin online.

I cannot give you feedback on how they work yet because I haven’t put them in. My concern is why I would pay the same price for a. 20/20/1. 20As I did for a 12/12/1 ????

Very inconsistent in size. The actual dimensions are bigger for a filter in the pack, while a different filter has correct size to fit the vent opening. Very frustrating!!

Love these filters!! I have been using them for a number of years now and have figured out that changing them out every two months works best for me. I try never to run out of them even if I have to buy a single filter elsewhere occasionally.

4 pack that is in stock at the Sam's Warehouse. When on sale, I purchase them, and with no expiration date, change the filter at my home once a month.

A necessary piece of equipment for every home’s furnace. I know price is a topic to avoid but compared to a 10 pack bought last year the cost has crazy skyrocketed! The only negative in this review.

Hi quality filter that works great. We change the filters every three months, seems about right here in the desert southwest. Great price at Sam's for a 4-pack, and usually in stock when we need to restock.

Been buying these filters for a while, they work perfectly in our house and really help eliminate odors, dust and other issues. Price is great when on sale and we stock up on them. Would definitely recommend them.
