Do ZeroWater filters remove minerals from water?Updated 2 months ago

Yes, ZeroWater removes minerals

ZeroWater's 5-stage ion exchange filter removes 99–100% of dissolved solids from your water, including naturally occurring minerals like calcium, magnesium, potassium, and sodium. This is why the TDS meter reads 000 after filtering — virtually nothing dissolved remains.

Is removing minerals harmful?

This is a common question. The short answer is: no, for most people.

While minerals in water can contribute to your daily intake, they represent a very small fraction of your total mineral consumption compared to food. Health organisations, including the World Health Organisation, acknowledge that drinking very low-mineral water is not harmful as part of a balanced diet.

If you have specific dietary concerns or health conditions, it's worth discussing with your GP or a nutritionist.

Why remove minerals at all?

The same ion exchange process that removes beneficial minerals also removes harmful dissolved solids — lead, chromium, nitrates, fluoride, pharmaceutical residues, and hundreds of other contaminants. ZeroWater removes them all, without distinction, giving you the purest possible filtered water.

What about remineralisation?

Some customers choose to add a remineralisation drop or electrolyte product to their filtered water. This is completely safe and simply comes down to personal preference — it won't affect how well your filter works. A popular option is Third Wave Water, which is designed to restore minerals for taste or for specific brewing needs like coffee and espresso.
