The Technology Behind bluu dragon
9-Stage High-End
Filtration System
Water as natural as possible. German-engineered. Guaranteed for 30 years.
Every drop of bluu dragon water has passed through this system. No shortcuts, no compromises. Here is exactly what happens — stage by stage.
How it works
The 9 Filtration Stages
After stage 6, the system transitions from pre-filtration to V4A surgical-grade stainless steel — preventing any recontamination by microplastics.
Filters sand, silt, rust, and other coarse particles down to 0.005 mm — as well as most bacteria and viruses.
Removes 99% of odours and organic compounds, THMs, TCE, chlorine, ozone, pesticides, and hydrogen sulfide.
A granular bead additive in the activated carbon causes dissolved calcium carbonate to crystallise — preventing limescale deposits from forming.
An additional additive that protects against highly harmful lead contamination — for example from old pipe connections.
The highly effective UVC germ barrier deactivates 99.99% of all bacteria, viruses, and germs — without chemicals.
Removes more than 99% of: bacteria, viruses, nitrate, arsenic, lead, cadmium, sodium, sulfate, calcium, magnesium, phosphates, chlorides, fluorides, radioactive substances, dioxins, organic compounds, THMs, PFAS ("forever chemicals"), pesticides, industrial chemicals, pharmaceutical residues, birth control pill residues, drug residues.
Acid-washed bio-activated carbon neutralises residual substances introduced via household pipes — and optimises the pH for optimal bioavailability.
The water's original crystal structure is restored — as it exists in untouched natural springs. Following the water science of Johann Grander (1930–2012).
A specially developed design enables a nature-like flow through 3D micro-vortexing — mimicking a mountain stream. The water's ability to carry and deliver energy is fully restored. Following Viktor Schauberger (1885–1958).
