how long does the filter last?

I've had a look into this for you and the lifespan of the filter will vary greatly depending upon how much water is used on each wash and how hard the water is. We would recommend using the filter only after completely washing and rinsing the car as usual with untreated water, then just use the filter as a final rinse to wash off the water residue (so use normal water to wash off the soap etc, then the filter to wash off the little bit of residue of normal water), so that only a few liters are used from the filter unit each time. It can be quite useful to meter this by filling up a watering can with water from the unit for the final rinse, the slower the flow the better the results will be. For this reason it's not really possible to say how many washes are possible before the filter needs changing as there are too many variables, however if the above advise is followed you would on average expect the following depending upon water hardness: Soft water area: approx 160 washes Average water hardness area: approx 83 washes Very hard water area: approx 50 washes
