Why Ultra-Pure Water (TDS = 0) Matters for Automotive Perfection?
Ultra-pure water (UPW) was once limited to the world’s most
demanding environments—semiconductor fabrication plants,
pharmaceutical labs, microchip production lines, and optical
cleanrooms. It is water that is completely free of minerals, ions,
and organic matter. In short, nothing but H2O.
Today, PurePro AW-400X brings that same zero-TDS
water quality to the automotive world—ensuring a flawless,
streak-free rinse for the most valuable surfaces on earth: your
car’s exterior.
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.
The AW-400X Solution: Six-Stage Ultra-Purification Technology
The PurePro AW-400X features a comprehensive 6-stage purification
system, designed to eliminate sediment, chlorine, heavy metals, and
all dissolved solids — delivering true zero-TDS ultra-pure water for
car detailing and paint protection.
Stage 1 – 5 Micron Sediment Filter: Removes sand, rust, and larger
particles to protect the internal components.
Stage 2 – Carbon Block Filter: Further refines taste, odor, and
chemical content; protects RO membranes.
Stage 3 – Carbon Block Filter: Further refines taste, odor, and
chemical content; protects RO membranes.
Stage 4,5 – Dual 200 GPD RO Membranes (Parallel Design): Effectively
removes up to 99% of dissolved contaminants including heavy metals
like lead, chromium, cadmium, nitrates, and fluoride — total output
of 400 GPD (1512 LPD).
Stage 6 – Deionization (DI) Filter: Final polishing stage removes
all remaining ions, achieving 0 ppm TDS and conductivity below 0.1
μS/cm — leaving absolutely no residue after evaporation.
Result: No water spots. No streaks. No wipe-downs. Just a flawless,
laboratory-grade rinse—ready for ceramic coatings, PPF, and luxury
finishes.
