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 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!

Best filters for your furnace

I've been using these filters since they were recommended by Any Hour Supply. I've been using them for 5 years now, these filters have done a better job than anything else on the market! Never any problems, very inexpensive in cost, but the quality is unmatched. We'll use these and only this brand for my air conditioner/Furnace ever more!
