Why Reverse Osmosis + Deionization?
When it comes to protecting your car at home, not just any water will do. The PurePro® AW-400X combines an advanced 6-stage purification system — featuring dual 200GPD reverse osmosis membranes and high-capacity deionization (DI) filters — to deliver 100% ultra-pure, zero-TDS water.
This eliminates water spots, mineral stains, and streaks completely, making it effortless to achieve a professional-grade wash in your own driveway or garage.
The PurePro® AW-400X brings laboratory-grade water purification into your home and garage — not just for professional shops.
Now, car lovers everywhere can enjoy a flawless, spot-free shine on their vehicle’s paint, chrome, glass, and coatings, right from their own garage.
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.
