Water Purity Stops Improving
Last checked: · 049-Rev3-L (reference-reported)
Direct answer
Repeated powered purification cannot overcome the current module configuration's contamination floor. In the structured Demo model, Quality changes that floor and Performance affects removal per run; another powered cycle may consume energy without improving the reading.
Read the contaminant that remains
Compare individual contaminant readings before and after a cycle. Determine whether the batch is still moving toward a floor or has stopped there. Increasing Performance is not the same as lowering the floor, and a higher Quality number within the same threshold may not change the limit.
| Quality 75 and 99 | Same reported floor multiplier |
|---|---|
| Quality 100 | 0.1 multiplier |
| Quality 200 | Zero floor multiplier; removal still bounded |
Separate powered and portable limits
The portable purifier rejects water at 98% or better in the reference, and UPDATE 049 fixes floating-point failures near that target. Neither behavior means all Pure Water must read exactly 100%. Record machine type, modules, volume and contaminants when comparing a result with a guide.
