Can I use ZeroWater filtered water in a kettle, coffee maker, or espresso machine?Updated 3 months ago

Yes — ZeroWater filtered water works well in kettles, coffee makers, and espresso machines. Because it removes virtually all dissolved solids, it can also help reduce limescale build-up in your appliance over time.

For espresso machines in particular, some users prefer to add a small amount of minerals back in for flavour and extraction. Products like Third Wave Water offer mineral packets designed specifically for this — you add them to your filtered water to restore a balanced mineral profile suited to espresso brewing. See "Do ZeroWater filters remove minerals from water?" for more on that.
