What Is Pure Water?
The term Pure Water in window cleaning describes ordinary tap water that has been filtered through a purifying filter system. This removes natural minerals from the water including Calcium which is the the main cause of white spots on the window when they dry.
Water is purified through an Reverse Osmosis (RO) System or DI Vessel (De-Ionisation) or a system that combines the two technologies in a single set up.

How Do I Test Water Purity?
You can test your treated tap water with a TDS Meter which measures electrical conductivity and produces a value indicating the level of dissolved solids in the water. For window cleaning purposes, a value close to 000ppm (parts per million) of dissolved solids is low enough to leave a streak and spot free finish on the glass. It's reasonable to effectively clean windows with readings of up to 10ppm.
