I had been using a cheaper change every month filter and decided to try these. They are made much better so thinking they may last two to three months. So far happy with my purchase.

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 usually buy the filter with less coverages, because I do not need the additional coverages, so I had to spend more money. My income is limited. I believe you should have more than one option to choose from.

Quality product that does the job our HVac person told us a good quality filter changed monthly will extend the life of our furnace/ac. And it certainly does.

Nice filters. We buy them when they are on sale. The multi pack is a better deal than buying them individually. They work great! We change them monthly during high allergy times. Can go longer at other times.

These filters cut dust and allergens down immensely in our home. The down side is they restrict the movement of air thus making the central air unit work harder.

I like this product. Seems to catch more airborn particulate than the cheaper filters. I have 2 rambunctious kittens, always stirring up dust bunnies while playing.

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!!

I love these filters. I can feel very confident knowing that all pollutants and contaminants are being filtered out. The added bonus I wasn't expecting was having less dust in my home.

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 ????
