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!

They Fit.

I had a new unit installed and the fan runs continuously. But my electric usage is down. I have four cats and one large hairy dog; live in a dusty environment and need to change filters every two weeks. The big box store was charging almost a dollar more for a MERV 5 filter and I had to bend them to get them to fit, which left gaps along the sides. These filters fit and they cost quit a bit less than what I would have paid for a MERV 8 in store.

Great Filter As Always

I've been ordering these filters for years. I change them somewhat often, every 60 days. My HVAC looks like new inside. It operates without any issues thanks in part to Filter Buy filters. Based on my experience(s), I recommend these high-quality filters.
