What is reverse osmosis, and is it right for your kitchen?

Reverse osmosis, or RO, is the step up when you want the best water to drink. It sits under your kitchen sink and feeds a filtered tap of its own.

How it works

Water is pushed through a membrane that filters far finer than a jug or tap filter. Stages before the membrane catch dirt and reduce chlorine, taste and odour. A mineral stage after it adds back a touch of minerals for taste.

What you get with Crystal

• Better coffee and tea. Taste the difference in your first cup.
• Clear ice, crisp water. Water that tastes clean, cold or straight from the tap.
• Its own tap. A separate filtered tap, or a 3-way mixer that does both.
• Out of sight. The whole system fits under a standard sink.

Who it suits

Crystal is for tea and coffee lovers, keen cooks and anyone who wants the best water to drink.

Crystal or Home Guard?

They do different jobs. Crystal perfects the water you drink at the kitchen sink. Home Guard filters every other tap, shower and appliance in the house.

Plenty of homes choose both. Home Guard handles Crystal's pre-filtering, and the Complete Home Package puts them in with one visit, one install and one fixed quote.
