Installation was simple, quick and explained very well! I had a pretty tight space to work in and the install still only took 10 minutes. The filter seems to be well made and working perfectly. Still seeing a loss of pressure after 6 days but, sufficient for use. Water tastes excellent! Thank you! Lee Murphy Satisfied customer.

I am a licensed plumber in AZ. I purchased a wellness system for my home to give it a field test. I was so impressed that I have begun recommending and installing for my customers. Too many benefits to list. Check out the website and you will find all the details.
