Ordered 2 filters on 11/28 with auto renewal. The Free Shipping was through Surepost (UPS transfers to Post Office) which is completely unreliable. Shipment was lost, PO placed tracker on it and we called FiltersFast as well. They would not send out a new order until they researched the first. Ok, but it's been several days with no communication and when I call customer service I was hold for 41 mins before I had to hang up. This will be my first and last experience with them.
