We first REMOVE POLLUTANTS from your tap water

TheWell 2 water filtration system removes all types of pollutants and odours from tap water, leaving you with water in its purest form.

The 4-stage filtration system consists of: :
  • A 1-Micron Sediment Filter filtering out larger particles to protect the reverse osmosis membrane and optimise its efficiency and lifespan
  • An Activated Carbon Filter to remove chlorine and other particles that create bad taste or odor.
  • A Reverse Osmosis (RO) membrane, which is the most efficient way to clean harmful paritcules from water, such as metals, microplastics, PFAS, hormones, pharmaceuticals and more.
  • A UV filter prevents any recontamination by bacteria from sources like the spout.

Essential Minerals for RO purified water

Then we make your purified water taste great by adding NATURAL MINERALS  

Truly pure water doesn’t taste good, so our remineralization capability adds back healthy, natural minerals and salts to deliver great tasting water.
This patented mineralization innovation is what makes TheWell 2 the best water purifier. It uses LANGWATER liquid minerals, which mixes instantly with the filtered water -no stirring or waiting for powder to dissolve. Our proprietary technology ensures a precise dose of minerals is infused into every serving, guaranteeing that the fresh taste of LANGWATER stays the same, from the first drop to the last. Our LANGPAKs are produced in Switzerland using natural ingredients and contain no sodium, as most diets already have excessive levels of salt. They are also free from the microplastic pollutants often found in PET water bottles.

And you can also instantly add flavors to obtain FLAVORED WATER +

We developed a range of natural fruit flavors and teas that make your good water taste even better. The basis is good mineralized water, the flavors are the plus... A key advantage of using natural liquid extracts rather than dry powder extracts is that liquid retains a more intense flavor. All our teas and flavors are made from 100% natural fruit and tea extracts because we want to enrich the good water we created not spoil it with additives or artificial flavorings. We love all things pure; that’s why we’ve also avoided sugar and made our drinks calorie-free.

Premium Mineral water   

LANGWATER tastes like mineral water - without the plastic

Companies that sell bottled water produce a lot of plastic bottles. Carrying and storing bulky, heavy bottles is not convenient.
At LANG, we don’t use any single use elements. One Mineral set produces 250 liters of pure mineralized water, sparing you the hassle of heavy bottles and helping to protect nature.
Additionally, TheWell 2 countertop reverse osmosis system with minerals requires no installation. Just plug it in and follow the setup instructions on the touchscreen or app.
Stay Healthy, Happy and Hydrated - easily and without the waste !
