Clean drinking water — without esoterics, without panic

We explain what's actually in tap water, which filters make sense, and which are pure money-grabs.

What this site is about

There's a lot of half-knowledge floating around about drinking water — from "tap water is toxic" to "you don't need a filter at all". Neither is true across the board. We work through the questions step by step: water quality, filter technology, limescale, microplastics, lead in old pipes.

Planned topics

Activated carbon vs. reverse osmosis

What each filter does, what stays in the water, what comes out.

Tabletop filters reviewed

Brita, BWT & co. — sense, nonsense, follow-up costs.

Under-sink filters

Permanently installed kitchen systems — when they pay off.

Water hardness & limescale

What hardness levels mean and when softening makes sense.
