UltraStream was designed in Australia in collaboration with QMP in California and produced at the QMP manufacturing facility which is a NSF, WQA certified manufacturing facility.
Alkaway decided to have the UltraStream made in California because of their "highest" water filtration standards in the world. UltraStream and our other products made by QMP are all made with NSF and WQA certified components.
Alkaway decided to NOT spend the thousands of dollars to have those certifications "attached" to the UltraStream. They already spent that and much more in the design and independent testing to know the results BEFORE making any defend-able claims. No other filter does full life-of-filter testing. No other filter is EU certified as "safe." These were not inexpensive en-devours.
So we understand if you have to have a NSF, WQA certified product.
