Water filters and water activation: foundations as an online audio course
Drinking-water debates often mix filter ads, mineral myths and activation claims. The free audio course keeps the order: understand what matters in water, then measure, then filter, then — if you want — activate.
Course in the SGA Learn Player (audio currently in German): Open the online audio course in the player.
What you learn
Water as a base — what really counts; measuring with microsiemens and PPM, including the limits of the numbers; filter techniques compared; activation and UMH without marketing fog. Two voices, about 30–35 minutes.
The course complements the water-filter articles on this site and helps separate readings from device promises.
