Filter cane very quick and seem to be helping!

I had difficulty attaching my filter to my faucet. They were very quick to help me and send me the correct part. I’ve been using their filters for many years and will continue to do so.

I recently ordered online 2 of the bath tub filters and they are great. Somehow there was a mix up regarding shipping, but once pointed out the mix up they fixed it right then. I appreciate that and plan to order replacement filters when needed from them.
