Why we picked it
It uses the same 5-stage cartridge family that IAPMO R&T certifies to NSF/ANSI 53 for lead, PFOA and PFOS, in a smaller jug that fits a fridge door. Culligan UK says it ships with a removable TDS meter so you can check when the cartridge stops working.
Best for
Single people or small fridges who want the same certified cartridge as the larger ZeroWater jug
Not for
Households drinking several litres a day, or very hard water areas
The details that matter.
- • Same certified cartridge type as the 2.8L ZeroWater jug
- • Comes with a TDS meter
- • Compact size for fridge doors
