RO Instant Hot Water Dispenser (with Filter)

RO stands for Reverse Osmosis. It is the gold standard of water purification technology, designed to turn standard UK tap water into exceptionally pure, bottle-quality drinking water.

Unlike basic filters that only improve taste, an RO system uses your home’s water pressure to force tap water through a highly advanced, semi-permeable RO membrane. This membrane has microscopic pores measuring just 0.0001 microns—roughly 500,000 times smaller than a human hair. Only pure water molecules can pass through, while over 99% of all impurities, chemical pollutants, and limescale-causing minerals are trapped and safely washed away down the drain.

Yes, absolutely. Hard water is a major issue across the UK (especially in London and the South), causing rapid limescale buildup in your kettle and coffee machine. A Reverse Osmosis (RO) system is the most effective solution available. Its 0.0001-micron RO membrane strips away over 99% of calcium and magnesium ions, completely eliminating limescale, preventing that unpleasant film on your tea, and extending the lifespan of your kitchen appliances.

Older RO models were notorious for wasting water, but modern technology has completely changed that. Our advanced RO water purifiers feature an eco-friendly low wastewater ratio (such as 2:1 or 3:1 pure-to-drain). This means for every 2 to 3 cups of pure, crisp drinking water produced, only 1 cup is sent to the drain. It has a negligible impact on your UK water meter bills while significantly reducing environmental impact compared to bottled water.

While it’s true that Reverse Osmosis removes minerals alongside harmful contaminants, it’s important to know that the human body gets 99% of its essential minerals from food, not from tap water. Drinking RO water is perfectly healthy and is the purest form of hydration.
