Does ZeroWater remove limescale?Updated 3 months ago

Yes. Limescale is caused by dissolved minerals such as calcium and magnesium, and ZeroWater’s 5-stage ion exchange filter removes these along with other dissolved solids.

Because ZeroWater removes virtually all dissolved minerals from your water, it also removes the minerals that cause limescale build-up in kettles, coffee machines, and other appliances.

Brewing coffee with ZeroWater

If you brew coffee, near-zero TDS water is actually the ideal starting point — but coffee does need some minerals to extract properly. That’s where Third Wave Water comes in: small mineral sachets designed to remineralise ultra-pure water like ZeroWater’s to the exact profile specialty coffee needs. Simply fill your ZeroWater jug, pour the filtered water into a bottle, and add one sachet of your chosen Third Wave Water profile (light roast, medium roast, dark roast, espresso, cold brew, or low acid) for more consistent extraction and cleaner flavour.

For the full explanation of what ZeroWater removes and why, see our article on whether ZeroWater filters remove minerals from water.
