Benefits

Others sell filters. We solve water. No hassle, no hype — this is what makes H2Ot different.

26 years of experience in water technology

Behind H2Ot is a water company with 26 years of experience in water treatment, worldwide. The same technology that works there day in, day out, we have brought down to systems for your home, your business and hospitality.

Proven technology, not promises

ZeNO softens water with salt/resin ion exchange — the method that, according to the Dutch Consumers' Association (Consumentenbond), demonstrably removes limescale.

Magnets and salt-free "green" systems don't take the limescale out of your water: at most they keep it suspended. When a drop dries, the limescale still settles — as a mark on your tap, your glasses or your shower screen. Ion exchange does remove the limescale, up to 100%.

You choose your protection

Just limescale out, or bacteria, viruses, PFAS and microplastics too? ZeNO, ViruLEX and SorCA work on their own, but also together. That way you choose exactly the protection that suits your water — from a single tap to your entire home.

With ZeNO: economical with salt and water

Our ZeNO water softener uses up to 60% less salt and up to 66% less water during regeneration than a standard water softener.

With ZeNO: you decide the hardness

With ZeNO you set how much hardness you want to keep in your water yourself — for example 2 or 4 °dH, or all the way down to 0.

With ZeNO: your appliances last longer

1 mm of limescale on a heating element can easily cost 10% efficiency on your boiler or central heating. Without limescale, your boiler, kettle and coffee machine run more efficiently and last longer — and you no longer need anti-limescale tablets.

Coffee and tea the way they're meant to be

Soft, filtered water brings out more flavour in your coffee and tea — fuller and cleaner, without a limescale film or chlorine taste.

One price, no small print

With ZeNO, shipping, a 2-year warranty on the main components and the first salt fill are simply included in the price. You arrange installation yourself, with the installer of your choice.

Systems and filters from European production

Our water treatment systems and filters are produced in Europe, by manufacturers we work with directly. No anonymous imported boxes, but the quality and certainty you are used to from European products.

Support from the Netherlands, delivery across Europe

We handle support from the Netherlands. And do you have a second home in France or Spain, for example? Then, where needed, we'll have your product delivered to that address directly from the manufacturer.
