Lena Hartman
Lena Hartmann co-founded POWERBOX™ Hard Water Filters Australia. She moved to Perth from Stuttgart, Germany in 2018. Germany has hard water in many cities. But Perth's northern suburbs hit over 200 mg/L. That's where she first lived. Limescale built up on every fixture. Her skin dried out. Her hair was rough after every wash. She tried product after product for two years. Nothing worked.
Then she started sourcing filtration products direct from manufacturers. She built POWERBOX™ to solve the exact problem she had. The 25-stage filter didn't exist in 2018. She built it. She has eight years in water filtration. She sources, tests, and improves shower filters for Australian conditions. She tests every new batch against real Perth tap water before it ships.
She is not a dermatologist or a doctor. For medical skin or hair conditions, see a specialist. POWERBOX™ filters improve water quality. They are not a medical treatment.
