FILOPUR AG

What FILOPUR AG does

FILOPUR AG is a Swiss family-owned company that designs, manufactures, and distributes point-of-use water filtration systems for private households. Founded in 1973 as a spin-off from GuteHoffnungHütte (Germany) to commercialize patented filter technology, the company is headquartered at Dufourstrasse 30 in Zürich and operates with 1-10 employees. Its product portfolio centers on the HU-Linie under-sink water filter and the Equator Duschfilter shower filter, supported by a modular cartridge system (C1 Standard, CN Nitrate, CK Lime, CA Pollutant, and KDF cartridges) that addresses specific water quality challenges including chlorine, heavy metals, nitrates, pesticides, and limescale.

The underlying technology combines Mikrofiltration at 0.4 micrometer pore size (capable of removing bacteria, Giardia, and cysts while retaining healthy mineral ions), Aktivkohle activated carbon from coconut shells, Silberionen silver ions for bacteriostatic effect, and KDF copper-zinc alloy for redox reactions. The Biophotone technology, licensed via a 2005 partnership with Biophotone International UG, claims biophysical water restructuring effects lasting approximately 24 hours. The C1 filter has reportedly undergone more than 100 independent laboratory and government tests over four decades. Products operate without electricity on standard water pressure and are designed for self-installation.

Filopur generates revenue primarily through one-time hardware sales plus ongoing replacement cartridge revenue. Distribution combines direct-to-consumer online sales (via regional websites for Switzerland, Germany, Spain, and International markets) with channel partners including wellnessproducts.ch in Switzerland and Orbit in Russia. Products reach over 30 countries across Europe, Russia, China, North Africa, and South America. Assembly and packaging are handled by ZUWEBE, a Swiss social enterprise employing people with disabilities, which serves as a key element of the company's CSR positioning and Swiss Made branding.

Core offering

FILOPUR AG develops, manufactures, and sells Swiss-made home water filtration systems, including under-sink drinking water filters (HU-Linie) and shower filters (Equator Duschfilter), built around patented Mikrofiltration technology (0.4 micrometer pore size) combined with activated carbon, silver ions, KDF redox media, and Biophotone biophysical water restructuring. The company also offers replacement cartridges (C1 standard, CN nitrate, CK limescale, CA pollutant) and ships directly to consumers and through distribution partners in over 30 countries.

Product overview

FILOPUR AG offers a comprehensive portfolio of Swiss-made water filtration products. The core offering is the HU-Linie, an under-sink water filter system featuring patented Mikrofiltration technology (0.4 micrometer pore size) that removes bacteria, particles, and contaminants while preserving natural minerals. The HU-Linie supports multiple filter cartridge types: the C1 Standard Filter (core component with activated carbon and silver ions), CN Nitrate Filter, CK Lime Filter, and CA Pollutant Filter. FILOPUR also offers the Equator Duschfilter (shower filter) and KDF Duschfilter for bathroom applications.

• Equator Duschfilter (Equator Shower Filter) The Equator Duschfilter is a shower filter designed for private households that reduces skin and hair drying. It removes chlorine and heavy metals from water and converts calcium into a more water-soluble form, making water noticeably softer. The filter includes Biophotone Technology to approximate spring water quality.
• C1 Standardfilter (Standard Filter Cartridge) The C1 Standard Filter forms the core of FILOPUR water filters. It uses Mikrofiltration with 0.4 micrometer pore size to remove bacteria, Giardia, cysts and other particles. The filter consists of nine layers with Aktivkohle (activated carbon from coconut shells) and silver ions for bacteriostatic effect, retaining healthy mineral ions. Sold as a standalone replacement cartridge.
• CN Nitratfilter (Nitrate Filter Cartridge) The CN Nitrate Filter cartridge reduces nitrate and nitrite content in drinking water. Harmful NO3 ions are removed through ion exchange and stored in the cartridge. The cartridge can be regenerated when capacity is exhausted, achieving a lifespan of up to 2 years. Sold as a standalone replacement cartridge.
• CK Kalkfilter (Lime/Calcium Filter Cartridge)
