Customer Testimonials

“It is a great product, easy to install and the water tastes as it should, no more chlorine flavor. Customer service is also excellent.”

– Verified Amazon Purchaser, Inline Refrigerator Filter

“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!”

– Mark R., Inline Connect FS10

“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.”

– Marina U., Handheld Shower System

“So grateful we found you. The Whole House System was a game changer for our family and we also appreciate the amazing customer service. I misplaced and needed the wrench to change our pre-sediment filter and it was on my doorstep a few days later. The water is amazing! We have really nasty city water and this system makes it delicious, clean and safe. I couldn’t stand the thought of purchasing plastic bottles spring water my whole life. I also take our Gravity System every time we go on vacation.”

-Erica S, ProOne^® Home

“I am happy with the ProOne Big for our kitchen. The water tastes good; it removed the smell from the city water which I did not like at all. The unit was easy to assemble. Before I bought ProOne, I had tried a [competitor unit]. However, the filtered water with the [competitor brand] was always cloudy even after several priming’s of the filters; so I had to return the [competitor product]. However, the ProOne unit is working very well for us.”

-Peggy P, ProOne^® Big

“Thank you for the incredible products you supplied us with, the speed of delivery, and the great service you & your team have provided. Our entire family is truly loving the shower filters and it has made a big difference already. We loved the bonus MisterX, just in time for a heatwave and perfect for many uses.”

-Tamara V, ProMax^TM Shower

Our Filter Technologies

ProOne^® filter technologies are like no other.

ProOne^® G2.0 Gravity Filter:

While we were not the first to offer gravity filters, our team of dedicated professionals has certainly excelled in developing the most advanced gravity filter technology offered on the market today. We’re proud to say the ProOne^® G2.0 series filter carries the highly regarded NSF/ANSI-42 component certification that helps make us known for our “all-in-one” gravity filters.

ProOne^®/Coldstream (Pressure) Filter:

Like the great taste and hi-performance of the ProOne® gravity filter? You can now find the same technology available in our pressure filter product line.

ProMax^TM (Pressure) Filter:

The same goes with our pressure filters featuring ProMax^TM filter technology. Based on our innovative infused micro porous foam technology, our ProMax^TM filters finish the job that our competitors could only start. With broad spectrum contaminant reduction, ProMax^TM is much more than just removing chlorine and chloramines.
