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.

I appreciate the the help

After first ordering the wrong size, I called to return them. I was prepared for an additional charge for the return and a higher price for the corrected size. Instead I was told to just donate the incorrect size and a new 6-pack of the corrected size sent immediately and received in 2 days! This was a perfect fit! Now I just have to change the filter in the A/C every other month and I'm set for the year! Thanks bunches!

Great service and product!

I always hated buying furnace filters. Box stores were always expensive, if they had them in stock. Filterbuy is a very decent price for buying a years worth a time. I change my furnace filter monthly due to have a smaller filter and also with pets. The shipment is always very quick and comes well packaged. Highly recommend Filterbuy!
