I purchased these prior to needing them but the price looks good and they look sturdy. I tend to change my filters every two months even though I have no pets but I do have allergies. If they hold up--I intend to put two of them in at the end of the month--I may get them on auto-renewal.

Says Merv 11 last 3 months, mine barely get 2. I have 2 dogs, 1 indoor/ outdoor cat, cook a lot (near the return) and live on a dirt road, so maybe my situation isn't the "norm"??

I have tried other companies that said they could make any size This was untrue. This company however had the correct filter in the correct size and shipped quickly.

We have used these filters for several years now. They work very well, con trol dust and pollen better than most. They are a good price and delivery is fast. Can't ask for more than that.
