    This product is amazing, since changing to our RO, our tea and coffee in the morning taste so much better and the calcium build up in the kettle is no longer a problem. Can’t believe how much difference it has made!

    Thanks you so much to the Crystal Water Team, you made this choice easy with great customer service and great prices!

    The quality of the tap water here at Jandakot airport is terrible, so the only water we drink here at Dunn Aviation is from our RO system from Crystal Water. In fact, I take a jug of water from the RO tap home ever night for my family.
