NOBANA COMPLETE U4 Under-Sink Ultrafiltration System

The NOBANA U4 is a 4-stage ultrafiltration system for customers who want clean, safe drinking water but specifically don't want a reverse osmosis system stripping out the natural minerals. The 0.01 μm UF membrane catches bacteria, cysts, sediment and chlorine while leaving the calcium and magnesium that give water its taste.

Key specs

• 4-stage filtration with 0.01 μm ultrafiltration membrane
• Removes bacteria, cysts, sediment, chlorine, odour
• Retains beneficial minerals and natural taste
• 2 L/min flow rate — fills a glass quickly
• NSF/ANSI 42 certified

Why we sell it — the right choice for customers who already have soft water (or a separate softener) and just want bacterial protection without the demineralisation that RO causes. We see this with families who add the U4 after their kids start drinking from the tap — peace of mind, simple maintenance, no electricity required.
