The Unpumped Series are systems designed to work at UK mains pressure, granted this is at least 43 psi / 3 bar. If you have water pressure below this, we recommend a system from our Pumped Series. 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.
Larger than our slim range of systems, the RO-100M utilises a larger final polishing stage with colour change deionisation resin, compared to only the smaller inline final stage in the slim systems.
These types of systems range from our smallest of 50 gallons per day up to 100 gallons per day. Above this capacity, there is no deionisation resin stage and the third cartridge on the bottom housing is occupied by another pre filtration stage to aid the reverse osmosis process.
