Tap System filters
Advanced or Nano: which filter for your tap?
The Puure® 3.0 Tap System takes two filters. Advanced filters your everyday water well. Nano is our most complete filtration, and the filter our lab tested. Both fit the same housing. If your water is hard, add the limescale option to either one.

The + option: one more stage, just for limescale
You asked us for a filter that also deals with limescale, so we developed one. Advanced+ and Nano+ keep the filtration of your filter and add an extra stage inside the filter, made specifically for limescale. The new filter reduces limescale (kettle, tea, coffee).
Same filtration, plus one stage
Advanced+ filters like Advanced, Nano+ like Nano. The + adds the limescale stage on top.
You may need it if
Your kettle furs up quickly, you see white marks on taps and glasses, or a film forms on your tea.
Same housing, same subscription
The + filter fits the same Tap System and is replaced at the same pace.
