Water Filters

For the car wash and window cleaning industry, the advantages are that using water which contains no dissolved impurities allows the user to leave the car or window wet, to dry naturally and with no trace of water marks. The use of these filters is not simply a case of just connecting up a unit and running water through it though.

  • Connects to your hosepipe or pressure washer effortlessly

  • Use to fully wash or just final rinse to reduce usage – the latter for best economy
