Reverse osmosis (RO) is the most advanced home water purification technology available. Unlike basic pitcher filters that only reduce chlorine taste, RO systems force water through a semi-permeable membrane with pores just 0.0001 microns in size.
This process removes virtually all dissolved solids, heavy metals, bacteria, viruses, pharmaceuticals, and emerging contaminants like PFAS (forever chemicals) and microplastics that standard filters simply cannot capture.

UK tap water meets safety standards, but "safe" doesn't mean "optimal." Recent studies have detected concerning levels of PFAS in UK water supplies, while microplastics and pharmaceutical residues continue to accumulate.
For families with young children, immunocompromised individuals, or anyone seeking the purest possible drinking water, RO filtration provides peace of mind that no other technology can match.
💡 Pro Tip: The G3P600's remineralisation stage adds back beneficial minerals after purification, giving you pure water with optimal taste and health benefits.
