Cleaner, lighter tasting water – with five-stage filtration

A five-stage system combines mechanical and ion exchange stages to remove organic and inorganic dissolved solids, lowering measured TDS to near zero. One stage specifically exchanges ions to capture dissolved salts and metals.

Markedly improved flavour makes tap water more pleasant to drink, encouraging higher household hydration. Clear TDS readings provide a simple way to confirm water quality.

Reduced harmful contaminants – thanks to IAPMO certified reduction

IAPMO certification confirms the filter reduces contaminants such as lead, chromium and PFOA/PFOS, alongside other heavy metals and fluoride noted in product descriptions. Certification follows recognised testing protocols for targeted reductions.

Greater peace of mind for households concerned about metal and chemical contaminants. Suitable for anyone wanting a verifiable reduction in specific pollutants.

Lower single-use plastic waste – with BPA-free components

All filter materials are specified as BPA free, and the replacement pack claims an environmental saving based on reduced bottle use. The pack format supplies two ion exchange filters for immediate replacement needs.

Cuts reliance on bottled water, offering a measurable reduction in single-use plastics per filter. Safe, BPA-free materials mean no added concern about plastic leaching.
