Which Car Wash System?
Water in Western Australia and other regional areas is often extremely hard, when primarily sourced from ground or bore supplies. Avoid small filtration units if you're in WA or treating hard water – they may not perform effectively. For best results, we recommend opting for a larger unit:
- Either 10" x 4.5"
- or the 20" x 4.5"
Key Benefits
- Removes calcium and other minerals that cause spotting and water marks
- Utilises ion exchange deionising resin for hardness reduction
- Significantly improves rinse results on vehicles, reducing salinity and spotting
- Perfect for use after washing to achieve a showroom finish
Filter Capacity & Performance
Performance varies by water quality. Typical life expectancy on town water (TDS ~250ppm):
