Good price, in stock, and very fast delivery! Ordered on a Thursday at 4:30 PM and received the package on Friday the next day! I did not pay for expedited shipping. I am only one state away but I ordered late in the day. I have been buying my filters from them for years now and have never been disappointed!

I ordered a 20x25 furnace filter and the price was right, communication excellent and shipped fast. Had a great experience with this company

Ordering process was easy. Filters were less expensive, shipped right away and we're the exact ones I needed. This might not sound like a big thing, but it is getting harder and harder to get good service like this.

The order shipped quickly and is genuine Lennox filters.

BEWARE! I purchased an OEM furnace part, they sent me a cheap knockoff, not OEM. I even called before placing order to confirm it was OEM product.

Buyer beware. They advertise the size you need by picture and dimensions and send you something you that is too large. You call to return the item and they say that I should have read the actual size (In smaller print) not what their model sample displayed. Sounds like a bait and switch tactic.

First time using this company, and just WOW. I ordered the filter on Monday, paid for "standard shipping" and received the order in ONE DAY, by FedEx. Since I had not ordered from them previously, I thought I would get just one, in case there were problems. I also liked that PayPal was an option, so I didn't have to give out card info. I will definitely be ordering from this company *every* time I need filters. My new furnace came with a hard-to-find size filter, but they had exactly what I needed. They also sent immediate confirmation of order, then tracking info. I would give 10 stars if I could. Highly recommended.
