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 ????

Product is super, packaging was perfect. The FEDEX delivery left slot to be desired. The tracking process reported as on truck in area on Wednesday. The order was "out for delivery" on Thursday, Friday, Saturday and finally delivered on Sunday.

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!!

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 believe the filters are good but the first one I put in seemed to get used up pretty quickly. Also didn't appreciate having to pay the shipping fee because they didn't have my size in store.

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.

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!

Fair price and high filtration. We change the filter at the start of every new season so four will last one year. They are well made and indeed do the job.

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.

With two heavy shedding canines in the house along with the dust that magically appears daily, these filters a must in our house. They really trap an amazing amount of "stuff" which helps to clean the air in our house.
