Countertop Reverse Osmosis Systems – Pure Water Without the Plumbing 


A countertop reverse osmosis (RO) system is a self-contained water purifier that sits on your worktop. It gives you reverse osmosis drinking water without fitting an under-sink system or drilling a tap hole. At Wrekin Water we stock Ecosoft countertop RO systems that combine multi-stage RO filtration with UV sterilisation and instant hot water, all in one compact unit.

How does a countertop RO system work? 

You fill the unit's built-in tank with ordinary tap water (or, on some models, connect it to your supply). A pump pushes that water through a reverse osmosis membrane. The membrane has pores so fine that dissolved salts, hardness minerals and many contaminants are held back, while purified water passes through. That water is then UV-sterilised and stored ready to dispense. The machine does the work a plumbed-in RO system does, without the pipework.

 Who is a countertop RO system for? 

  • Renters and flat owners 

    who can't, or don't want to, alter the plumbing under the sink.

  • Hard water households. 

    RO strips out the calcium and magnesium that form limescale, so the water you drink and boil leaves far less scale behind.

  • Small Offices 

    that want a single point for purified, hot and chilled water.

  • Anyone trying to cut out bottled water 

    and the plastic that comes with it.

Frequently asked questions

It is a freestanding water purifier that sits on your worktop and uses a reverse osmosis membrane to remove dissolved solids, hardness minerals and many contaminants from tap water. Unlike an under-sink system, it needs no pipework or dedicated tap. You fill its tank and it purifies the water, UV-sterilises it and dispenses it on demand.

The Ecosoft CROSS RAY needs no plumbing at all: you simply fill its built-in tank. The Ecosoft Spark Smart can run from its built-in 5-litre tank or be plumbed into your water supply. Both plug into a standard mains socket to power the pump, heating, UV sterilisation and display.

Reverse osmosis removes most of the calcium and magnesium that cause limescale, so water from a countertop RO unit leaves far less scale when it's boiled. Both of our Ecosoft models also heat water themselves, up to 100°C, so you may not need a kettle at all. A countertop unit only treats the water it dispenses. To protect your whole home's pipes and appliances, look at a water softener instead.

Choose countertop if you rent, want no installation work, or would like hot and sparkling water from the same unit. Choose under-sink if you want a dedicated drinking water tap, a higher daily output and a clear worktop. If you're unsure, our team can recommend the right option for your home or office.
