The correct filter arrived promptly. I have ordered several times from FiltersFast. The order is always shipped by the next day with good packaging so the filters do not get crushed. I will continue to order from them.

I like the product. Yet, I want to cancel my subscription. I received an unexpected replacement filter when my current one did not need replacement. Also, the cost was much more than buying one from other sources.
