What Is Reverse Osmosis?

Reverse Osmosis is a process that takes any water back to pure, by putting water through a series of different filters and membranes.

How Do Our Reverse Osmosis Systems Work?

Our Reverse Osmosis (RO) Systems are fitted to your mains cold water, usually near your kitchen sink. They work using a pump to push water through 5 stages of filtration. Each filter does a different job in the purification process. The filters we use are industry leading technology in water purification. When it comes to water we don't mess around. You deserve the best.

Best Place to Install a Tap

Normally in the corner of your drainer, or on the edge of a worktop. However, you can choose one of our tri-flow taps which start from as little as €199.

What If I Don’t Like My Water Filter?

If for any reason you are not satisfied we’ll come and take the system out and refund your money. No strings attached.

Do I Have To Have A Separate Tap for My Water Filter?

That's up to you. You can have a separate tap or choose from our stylish range of tri-flows. Have a look here.
