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 ????

this is the greatest value on a four pack. Just buying one of these in the store is around $18. Great price this was for 39.98 for 4. Best ever filter

Great product. It does what it says it's supposed to do. I change them every 3 months. I had my furnace looked up and they said it's one of the cleanest they've seen in a long time.

Since I have terrible allergies, I appreciate the utmost filtration of the air inside my home. These help achieve lower pollen count inside my home, therefore improving my quality of life.

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.

These filters catch the dust and pollen that others let through. I am very pleased with these filters, they are not as inexpensive as the others but do a better job., NO MORE SNEEZING.

Great price on a great product. We have a couple of rescue dogs that shed. That means I always have a need to change my filter often and to always use a good one. This fits that perfectly.

Quality of filter seems great. We have our first set in now. The frame holds up nicely. It fits snug. I am noticing a “clean” smell from the air filters when my air conditioner kicks on.

Better quality filter for about 25% less than what they charge at the major home center retailers, and that was before the additional members savings I received.

This model filter is the best. It's a full boxed filter so it holds up well in a strong blowing ac. Doesn't cave in like lot of other filters. And filters good also. Always purchase these. Good price for four pack.
