How to make pure water for window cleaning

How do you make pure water for window cleaning? We know that cleaning windows with filtered water has lots of benefits; eco friendly, safer, better longer lasting cleans, ability to clean window frames; sills; doors easier. But you can’t just use tap water for cleaning windows using the Water Fed Pole method. This is because of all the impurities in the water, which when the water dries, would dry streaky. Filtered water has got to be used.

But where does the pure water come from, and what process is used to filter normal tap water to be pure enough for window cleaning? We use a 5 stage filtration process. Here is how it works

1. Sediment Filtration

   Firstly, the tap water passes through a 5 Micron Sediment Filter. This is made from 100% Pure Polypropylene Fibres and at this stage we are removing physical particles from the tap water. This could be elements of dirt, sand or metallic trust.

2. Carbon Block Filtration

   Secondly, we use an activated carbon block filter to reduce the concentration of chlorine and other organic compounds that can be found in the water. This specifically removes Trihalomethanes, Pesticides, Volatile Organic Chemicals and 99.95% of Giardia and Cryptosporidium Cysts.

3. Reverse Osmosis

   The next stage in purifying our water ready for window cleaning is using reverse osmosis. The water passes through 2 RO membranes. In simple terms, the membranes are very fine filters which allow pure water to pass, but reject ions and salts.

4. De-Ionisation

   The final stage we use to ‘finish’ off our water, ready for window cleaning uses a deionisation filter. Here, we will achieve a TDS reading of 000PPM. Which means there is 0 particles other than pure water in 1 million particles of water.
