100% BPA Free Reverse Osmosis
Completely BPA-Free
The BPA scare was directly due to information coming from some polycarbonate plastic materials. These are the hard shatter-resistant clear (or colored) drinking water bottles and things like baby bottles. Typically you will not see any BPA in plastics like polypropylene or PE as it is not one of the plastics used in the processing of the material. NSF does scan for BPA, so if there was elevated levels in the product it would fail the material extraction test.

Product FAQs

Product FAQs

  • If the RO system takes out everything in the water, bad and good, don't you need to put the good minerals back in? Does your system do that?

    Water is not a significant source of minerals. If you drank a bathtub full a day you might get 20%.  Yes, it takes the minerals out – food and supplements are the main source of minerals.  Water is not a major source of minerals so why do people focus on what RO doesn’t do (minerals) instead of what it does do (remove up to 40,000 dangerous chemicals).  It’s pretty silly!

  • I was just looking at the manual, and diagrams. I noticed that the RO storage tank has a line feeding it but not one out of it. I would expect and inlet and outlet. How does this work with only one line?

    It works like every other RO:  It has a bladder that is pressurized.  That’s how every new well tank operates too.
