Mixed Bed DI Resin - 25L Bag

Mixed bed deionising (DI) resin for pure water window cleaning. It strips the remaining dissolved solids out of your water so it dries spot-free on glass, bringing TDS down to 0 ppm.

• Type: mixed bed ion exchange resin (cation + anion), loose fill
• Bag size: 25 litres, approx. 20 kg
• Use: refilling DI resin tanks and refillable DI cartridges, whatever brand of system they're on
• Coverage: fills our 11L Resin Tank 817 (PW-TNK-0817) about twice

When to change: test the output with a TDS meter and replace the resin once it starts reading above about 10 ppm.

Make it last longer: run it after a carbon pre-filter and an RO membrane so the resin only polishes the last few ppm. Keep opened bags sealed, out of the sun and don't let the resin dry out.
