Delivering a spot free rinse every time. Our SF-20W Car Wash filters use DI Resin to remove mineral ions and provide an ultra-pure demineralized water with a very low TDS (Total Dissolved Solids).

Spot Free DI water is a dream for vehicle and window washing, cutting the time used for drying by ensuring residual water won't leave any spots.

Typical DI systems are designed for professional use and utilize large tanks that would prove cumbersome to the average consumer. Our filters eliminate the need for a large system, offering a quick and easy solution for deionized water for personal use.
