The D-IONIZR water filtration system has been designed to make washing simple.
With the bigboi D-IONIZR system it allows you to wash your car without the
inconvenience of water spotting during the washing / drying process. Let's breakdown how the unit works.

The first filter is a composite carbon filter which is designed to remove the hardness levels of your water. This also adds an extreme benefit to the D-IONIZR filter as the water flowing through it will be much cleaner, prolonging the life span of your cartridges. We have seen a 20% increase of the D-IONIZR cartridge with this set up.

The 2nd filter is a deionized resin that will filter the water to 0 PPM (parts per million). The newly developed bypass valve allows the user to simply choose if they want to use the filter system for the complete wash cycle or just during the final rinse cycle to prolong the cartridges life span. Bigboi has seen benefits to use the system during a complete wash cycle by seeing better foaming during the wash process with deionized water. Using this system during a complete wash is optional and can be adopted if desired. The built in digital TDS meter will read the incoming and out going TDS water hardness levels, notifying of the units performance.


1 standard de-ionize cartridge will approximately filter 1200 litres on its own.
This is based on your water hardness level to be 100TDS or lower. When working in line with our carbon filter it will achieve 20% (1440 litres) more efficiency subject to your
water levels. Based on using the system just during a rinse cycle you will be able to use it
between 80-96 washes.
