IX resin for window cleaning
This is virgin IX resin is specifically recommended for portable DI systems. It lasts 20-30% longer than non-virgin resins and will bring your TDS down to 00.
'Total Dissolved Solids'. In water, this means the number of minerals and other things dissolved in the water. For perfect results in window cleaning, we need 000 TDS.
PPM stands for 'Parts Per Million'. In window cleaning terms we use this to describe how pure water is. So if you took exactly 1 million particles (molecules) of water and counted out how many of them are NOT water molecules, you would be counting PPM. It's generally accepted that we need a maximum of 10PPM to get good results on the glass.
In reality, rather than trying to count microscopic particles, we use a small tool called a TDS Meter to measure the water purity by an electrical process. This is able to tell us the PPM of the water, or the TDS (see above). Once you have one of these meters and start using it in various locations you’ll be amazed how much variation there is in water quality from place to place.
