Total Dissolved Solids (TDS) removed from your water

Single-use plastic bottles saved by each 5-stage filter.

ZeroWater 5-stage filters recycled annually

When should you replace the filter?

It is unfortunately not possible to give an exact lifespan for the filter. This is because the amount of dissolved substances and possible pollution is different per location.

To know when to replace the filter, you will therefore receive a free TDS meter with every jug. You put this in the water every week to test whether it is time to replace the filter.

Would you like to know more about the TDS meter or how to assemble the water jug? Then read the full manual.

Be careful!

Do not use with water that is microbiologically unsafe or of unknown quality without adequate decontamination. Unless otherwise stated, municipal water is drinkable.

Important to know:

ZeroWater also filters all good minerals from your water, so we recommend adding 2 drops of multi-trace to your water daily for the optimal amount of minerals and trace elements.
