BWT
Adding magnesium back into the water on the way through, on the argument that filtration strips out things worth keeping.
Good at
- Magnesium mineralisation gives a rounder taste, and it is measurable rather than marketing
- Well regarded for tea and coffee — the flavour extraction difference is real
- Some cartridges are made to fit Brita MAXTRA jugs as well as BWT's own
Watch out for
Costs more per cartridge than Brita and the magnesium is not a health claim, whatever the box implies. Thin availability outside Europe.
