We just put the filter in, so we’ll see how it works. But the customer service has been outstanding.

Review by Whitney E. on 28 Mar 2017review stating The team at Filter buy
The team at Filter buy took good care of me. They are fast and responsive and the filters they supplied work great. I will continue to shop with them. I never have to go to the hardware store again with a list of what I need to buy. I can have it arrive at my home with free shipping.

Q: what is the difference between a merv 16 and merv 13? Are the interchangeable?

Our MERV 13 replacement should work just fine for any residential use. Thanks!
