How To Install
Spoiler alert: Hard water isn’t a health hazard!

Would you believe it? There’s nothing wrong with hard water.

In fact it’s healthier than ‘soft’ water because, unlike rainwater, hard water contains minerals. Natural minerals, such as calcium and magnesium, collected on its journey through soil and rock, which help build strong bodies and brains.

But what about limescale?

The only real worry is the costly, crusty limescale.

Limescale is the villain. The result of layer upon layer of Calcium Carbonate, limescale can clog the pipework in your home and radically reduce the efficiency your boiler, washing machine and showers. Removing limescale can help reduce your energy bills by around £40 per year.

No one likes a furry kettle. And limescale leaves scum around your kitchen sink, bath taps and shower doors that can be a pain to clean. Treating the minerals makes cleaning so much easier.

Who doesn’t love a super bubbly bath or shampoo that actually foams! By treating the water you use less shampoo and washing powder, and get better results. As a bonus, treated water has helped lots of people with itchy, sensitive skin to feel just a little bit calmer.

The real win-win is for your family and our planet. As you flush away fewer chemicals and burn a little less energy, you can enjoy knowing that you’re making another small contribution to minimising our impact on the earth.
