The Waters BioMax 4-stage under sink water filter system delivers high-quality drinking water directly from your tap, without taking up valuable bench space. Designed for homes where space is limited and water quality matters, BioMax provides clean, great-tasting alkaline mineral water at the point of use.

Developed over more than two years to closely replicate the performance of Waters Co benchtop systems, BioMax reduces unwanted taste and odour while targeting common tap-water contaminants. The system operates without electricity and delivers a steady flow rate of approximately 0.75 litres per minute, making it ideal for everyday drinking and food preparation.

Please note, the tap/faucet is not included and must be selected separately to suit your kitchen setup/design needs.
