LAGUR A/S
About
LAGUR A/S, founded in 2014 and based in Denmark, produces a patented chemical-free water conditioning system that prevents limescale without salt, chemicals, or ongoing maintenance. The company's name originates from the runic word for water. LAGUR's technology uses electromagnetism to convert calcium carbonate from its adhesive calcite crystalline form into aragonite, a powdery variant that does not bond to surfaces and wipes away easily. Installed downstream of the main water meter, a single unit conditions water for an entire building. The product line comprises LAGUR HOME, rated for residential use at approximately 2 kWh per week with a five-year warranty and available from 11,966 DKK purchase or 299 DKK monthly lease, and LAGUR PRO, covering DN20 through DN100 pipe connections for housing associations, hotels, restaurants, and public institutions at roughly 1 kWh per day with a ten-year warranty. The Danish Technological Institute independently validated that residual limescale is up to 2.1 times easier to remove with LAGUR treatment. The company holds an Environmental Product Declaration and won Borsen's Green Gazelle 2025 award. In 2025, new majority shareholders with leadership backgrounds at Grundfos and Xylem joined to accelerate European expansion, and over 50,000 Danes currently benefit from several thousand installed systems.
