“Too often these days, people only contact customer service when there is a problem.  Today, I want to let ProOne know the customer service representative I spoke to yesterday was absolutely exceptional in every way!  She was professional, helpful, personable, and fun to talk to in general.”

“I installed an FS10 with a dedicated faucet in the kitchen of our cottage this year. We draw water from our lake so I also installed a pre-sediment filter to help extend the life of the FS10 filter (and our water heater). Water quality is excellent. Water pressure/flow is excellent too. No need to cart in bottled water any more. Love it!”

“This shower filter is so much above my expectations: easy installation (no leakage of any sort with very little effort on my part), wonderful wide shower head, powerful water flow, and chlorine-free water. So happy I gave it a chance.”
