The LANG 4-Stage filtration system

TheWell 2 features an advanced filtration system designed to remove a wide range of contaminants, including arsenic, barium, cadmium, chromium, copper, fluoride, lead, radium, selenium, viruses, bacteria, hormones, pesticides, pharmaceutical traces, PFAS and microplastics. It consists of:

  • A 1-Micron Sediment Filter: Removes larger particles to protect the reverse osmosis membrane, maximizing its efficiency and lifespan.
  • An activated Carbon Filter: Effectively removes chlorine and other compounds responsible for bad taste and odor.
  • A Reverse Osmosis Membrane: A highly efficient filter that eliminates even the smallest harmful particles.
  • A Post-RO UV Filter: Ensures bacteria from external sources, like contact with the spout, cannot recontaminate the water.

No-Installation Osmosis System

More Compact, Quiet with 70% water efficiency

We further miniaturized the LANG technology to create a smaller TheWell, with a width of only 21 cm, its freeing up more space on your countertop!
The noise level has been significantly reduced for nearly silent operation.
We recirculate the filtered water to avoid typical RO water waste and achieving 70% (ratio 2.3:1) efficiency while preserving filter life through advanced technology.
Additionally, the machine boasts remarkably low energy consumption at just 4Wh per liter.

Safest Technology: Cleaning water... and keeping it clean!

  • Tankless: TheWell 2 filters water as it serves, and with its fast, high-capacity system, LANGWATER drinks are prepared instantly without the need for built-in storage tanks. Unlike other standalone filtration solutions, TheWell 2 is tankless to prevent water stagnation and post-filtration contamination.
  • Enhanced hygiene with BioCote® material: We use BioCote® on on all plastic parts, internal and external in contact with water inhibits surface microbial growth
  • Swiss precision: Additionally, it features a sophisticated control system with load cells and smart sensors that monitor all components, including pumps, valves, and the boiler. This ensures optimal filtration, precise heating temperatures, and accurate mineral and flavor dosing.

Packed with numerous patented technologies, TheWell 2 represents the pinnacle of safe, efficient, and advanced drinking water purification.
