Why Every Coated Car Needs Ultra-Pure Water—And the One System That Delivers It All
Ceramic coatings and PPFs are investments meant to protect your car’s finish. But rinsing with tap water can introduce minerals and contaminants that destroy the clarity, create etching, and lead to ugly swirl marks.
That’s why the PurePro® AW-400X is the trusted choice for car enthusiasts, luxury car owners, and professional detailers around the world.
With its six-stage RO+DI filtration, this system guarantees zero TDS output—leaving your car’s surface spotless and perfectly reflective, without the need for towel drying.
Perfect for black vehicles, the AW-400X helps avoid swirls and water marks while preserving a glassy mirror finish.
