We decided to filter at
We decided to filter at the cold air returns rather that at the air handler. The goal was to reduce the amount of dust in the house. The 12x12x1 filters fit the returns perfectly. We've noticed no difference in air flow. It's too early to determine if there is less dust. The filters are of high quality. If the change we made in filter location works the way we want, we'll definitely be purchasing more from Filter Buy.

Great find!
My a/c went out a couple weeks ago (when it was 3 million degrees). I asked the repair man about air filters. He told me that the expensive filters tend to not let enough air through. So, I'm thrilled to have found Filterbuy! A great price and seem to be doing their job. Will definitely continue buying them.

I really love getting my filters
The convenience of getting my filters by subscription is great! I never have check the size and then remember to get them at the store then get them home without crushing them in the car. I was buying them several at a time but that took up a lot of space. I am very happy with the price, quality and convenience.
