What's inside
The cartridge at the heart of every Mam Nature system.
One filter. One installation. One 10-minute swap a year.

At the heart of every Mam Nature system is one cartridge, built around our patented Aqualen™ media — natural protein fibres bonded to activated carbon. Independently tested at ETH Zürich (Bolisetty et al., 2025).
Aqualen™ is a selective-adsorption media. It binds contaminants on the fibre surface while letting essential minerals pass through. Removal rates vary with source-water chemistry and contact time — see the full report for stated conditions.
