SKU N/A Category

The Slim Series reverse osmosis systems make use of only two stages of filtration pre the reverse osmosis stage, as opposed to the more conventional three stages of pre filtration. This cuts the size of the system down considerably, making it is easier to fit into smaller working spaces. Also, the reduced weight and ability to operate at mains pressure (43 psi / 3 bar) increase the ease of initial setup and use throughout its service life.

This range of systems spans from our smallest of 50 gallons per day, up to our largest of 100 gallons per day, each contain a final polishing stage by utilising colour change deionisation resin. All RO systems can be purchased with customisable consumables. Some are designed to target specific contaminants, eg. Chloramine, and others are rated at increasing efficiencies depending on the quality of your source water, and how long you would like your filters to serve for. Never use Deionisation resin if you are intending to drink the treated water.
