“I’m an engineer, and this system impressed me with its smart design. Dual RO membranes, DI stage, and a reliable TDS meter. I paired it with a 40-gallon tank and the M2 upgrade kit—now I have spot-free rinses and emergency-grade drinking water ready. This is more than just a car wash solution.”

6. Anna W. – Denver, Colorado

“I’ve owned several water systems, but none as compact and powerful as this. As a woman who does all her car care DIY, I loved how clear the manual was—I installed it myself in under 20 minutes. Now I have perfect rinses and 28 gallons of backup water in my garage.”



7. Tariq Z. – Las Vegas, Nevada

8. Mei L. – Seattle, Washington

11. David B. – Chicago, Illinois

19. Derek J. – Detroit, Michigan

The Problem with Tap Water


Even treated tap water contains microscopic contaminants:

Calcium

Magnesium

Silica

These minerals remain on your car after rinsing and create visible water spots, dull finishes, and micro-etching. Over time, they break down ceramic coatings, degrade paint protection films, and ruin surface clarity—especially on dark-colored or high-gloss finishes.
