First softening…

With BWT’s groundbreaking OnePipe Pearlwater, the softest Pearlwater flows from every tap setting new standards in hygiene, efficiency, and everyday comfort. Because around 98% of household water is used for washing, bathing, and cleaning, this is where silky-soft water makes the greatest difference, helping to protect appliances, save energy, and reduce costs from just one pipe.

And with the BWT Best Water App giving you gentle, intuitive control whenever you need it, you’re always connected to the wellbeing of your home’s water.

…then mineralization

The Pearlwater Mineralizer Kitchen Set brings a new level of drinking water straight to your tap — whether you live in a family home or a city apartment. Installed discreetly under almost any sink, it transforms softened Pearlwater into fresh, mineralised drinking water by filtering out chlorine, heavy metals, sediment and other unwanted contaminants, then enriching it with magnesium, calcium, silicates and hydrocarbonates for a naturally smooth, refined taste.

Only 2% of the water we use is for drinking — and it deserves to be the best. With BWT, getting perfectly mineralised water is effortless: simply enjoy it at the touch of a button, from your kitchen tap.

FAQ

What’s the difference between normal soft water and BWT Pearlwater?

Normal soft water still contains a little hardness, so over time you can still see some mineral deposits. BWT Pearlwater is different. With OnePipe Pearlwater Technology, the water can be softened right down to 0.0 ppm, meaning no limescale at all.

At the same time, the Pearlwater Mineralizer adds back essential minerals like magnesium, silicates, and bicarbonates, which are beneficial to your health – so the water feels balanced, tastes clean and natural, and is perfect for drinking straight from the tap.

It’s soft, mineral-rich water without compromise: beautiful to use, lovely to drink, and free from limescale worries, with the perfect balance of minerals.

How is the BWT OnePipe Pearlwater system installed in apartment buildings or multi-family homes?

In larger buildings, the system is installed in two simple steps. First, a central softening unit treats the incoming water for the whole property, ensuring every home receives beautifully soft, limescale-free water.

Then, inside each apartment, a compact Pearlwater Mineralizer can be added to gently enrich that softened water with essential minerals.

This means every resident enjoys their own supply of perfectly balanced, great-tasting water straight from the tap – with all the benefits of soft water throughout the home

What are the benefits of soft, mineralised water?

Soft water takes the pressure off your home by stopping limescale before it starts. Pipes, taps and appliances stay cleaner for longer, and everything runs more smoothly.

With OnePipe Pearlwater, softening goes all the way to 0.0PPM, giving you completely limescale-free water throughout the home. Then the Pearlwater Mineralizer adds back essential minerals, creating water that feels gentle, tastes beautifully balanced, and fits effortlessly into everyday life.

How long do the Mineralized Cartridges last?

The cartridges supplied with your OnePipe Pearlwater system deliver approximately 3,000 litres of beautifully mineralised water — enough for an average of 12 months of everyday use. Should your household usage be higher, additional cartridges are available to order from the BWT Shop at a competitive price, so you’re never without great-tasting water.

Do I need to replace my tap to use the Pearlwater Mineralizer Kitchen Set?

No, you can keep the tap you already have. The Pearlwater Mineralizer Kitchen Set fits neatly under your sink, so you get beautifully soft, perfectly mineralised water straight from your existing tap. Without the need for a new tap, there is less disruption and no unnecessary added cost. Just better water, right where you need it.

How easy is it to look after the OnePipe Pearlwater system?

The OnePipe Pearlwater system is designed to be effortless to live with. The central softener quietly keeps your home limescale-free with very little attention needed. Using the BWT Best Water App, you can check in on the system at any time — simple, clear and always in your pocket. And in the kitchen, the Pearlwater Mineralizer works continuously in the background, adding essential minerals to the softened water so you always enjoy perfectly balanced, great-tasting water with almost no effort at all.
