Excellent Customer Service Response First time ever, I received the wrong order. Size sent was 17"x25"x1". Mine were supposed to be 20"x21.5"x1". I called them and they apologized and said that they would immediately send out the replacements. So the rating is the middle ground. 5 stars on the customer service and 1 star for the original order. Great Company to work with and excellent products. Update: The replacement filters arrived four days later.

Initial request on order asked for any… Initial request on order asked for any further contact on sales, prices or sizes be sent to receiver of first order. They are still coming to me who has no need of them to the address they where sent to,which does. Please do so as requested. Thanks Other then that, EXCELLENT SERVICE!

Absolutely great customer service Absolutely great customer service. I purchased six MERV13 filters before learning that the filter could damage my HVAC because the motor wasn't strong enough to handle them. Four months later I called FilterBuy on the off chance that I could return them for credit. The customer service rep was was not only friendly, she gave me a total refund. I offered to return them at my expense, and she told me to donate them, which I did.

Low price filters here are better than… Low price filters here are better than comparable filters from big box stores. Before filterbuy, my filters were bowing inward. The cardboard frame is very sturdy keeping my filters straight after a month. Which leads me to the subscription, it's a good and easy reminder to change. I'm an HVAC technician, I'm happy with this service and I recommend them all the time.

The customer service was great The customer service was great. I needed a filter that was no longer listed by size. Other attempts to locate the filer met with negative results. Upon contacting filterbuy, their customer service took the time to assist me in getting the filter I needed.
