Deionisation and DI Resin

Interested in making your drinking water as pure and as healthy as possible? Using a Reverse Osmosis unit will ensure your water is filtered to the best possible form. Pure water means healthy and safe water - free of contaminants, toxins and other nasties - suitable for everyday use. To ensure your RO unit is working at its best, you’ll need DI resin. Deionisation is a resin based filtration process which removes all dissolved solids from your water. It works by attracting non-water ions and replacing them with water ions. This leads to an incredibly pure and high quality water.

Finest Filters offers the best Deionisation (DI) Resin and RO Resin filters as an ideal replacement resin for your RO unit. We sell resin holders and compartments which can be opened and filled with DI resin when needed. If your current RO unit doesn't have a DI stage, you can also opt for the DI chamber which includes housing, resin holder, resin, connectors and tubing. Luckily, all of our DI Resin and RO Resin are compatible with all RO holders.
