Filtration method

With a Carbon filtration system, the filter absorbs impurities from potable tap water such as odours, tastes, organic compounds and residual chlorine. The 321 filter tablet lasts around 125 refills, that is an amazing 62.5 litres of great tasting water before it needs replacing.

How this works is:

- If you drink 2 litres a day replace your 321 Water Bottle Filter monthly.

- If you drink 1 litre of water a day, replace your 321 Water Bottle Filter every 2nd month.

PLUS, if you don't already have a Stay tray to carry your Water Bottles, make sure you add one to the order today too :) The 321 Water Bottle is the perfect complement to your Stay tray reusable tray.
