Comparatif
The only criterion that matters:
what you can verify.
We do not publish any competitor metrics that we cannot prove. This comparison is based on the specifications advertised by each manufacturer.
A simple principle: concentration is checked with the DPD test. A few drops, the water changes colour, the level is read. Understand the method.
