D P Cleaning Services use a Reverse Osmosis 5 stage filtration system to purify the water. This filters consists of a micron sediment pre filter, a solid carbon block filter, a 0.5 micron Carbon filter & self cleaning reverse osmosis membranes. This filter typically reduces the impurity of the water to between 1 & 30 Parts Per Million (ppm), average kitchen tap water is between 340 & 550 ppm.

Finally the water is passed through a De-Ionising vessel prior to being pumped up the poles & onto the windows. The De-Ionising vessel reduces the water impurities to 0 ppm leaving a spot free clean on the windows.
