Very pleased

This filtering system was installed to removed hard water and chlorine from our drinking water. It works extremely well. Our water is so bad the filter needs to be replace at about 9 months versus the normal 12-month cycle. Not the system or filter’s limitation that we can see. Would recommend the system and filter.

No mineral buildup on appliances or shower head/glass.

Filter replacement

Five stars. Easy to find on-line, fast delivery, perfect on-line video for how to replace the filter with great tips (it's heavy). Thanks.

Hi Chris, Thanks for sharing your experience and we're glad to hear you found the video was helpful.

Clifford Bowen
Good Start

The filter was easy for a plumber to install. We are still evaluating the water softening to appliances and faucets. The water tastes fine.

Thank you Clifford, your review provides good information to others shopping for a easy to install water treatment system.
