Is your water hard? Start with a measurement
Understand hardness, read your supplier’s report and choose a test that answers the right question.
Read the guide →Hard water, shower filters, confusing promises. We turn the details into practical guides so you can understand the problem before paying for a solution.
Useful explanations, simple checks and questions to take to a supplier. No invented lab scores or promises of a cure.

Read the guide →Separate spray feel from filtration performance, and make a simple before-and-after flow comparison.

Choose a concern to see a useful first check. Your water supplier’s report is a good place to start.
| Solution | What to look for | What to avoid assuming |
|---|---|---|
| Shower filter | Independent evidence for the exact contaminant and model; rated flow, temperature and replacement schedule. | A chlorine claim does not prove hardness, chloramine or metal reduction. |
| Water softener | A measured hardness level, household capacity and maintenance costs. | Softening is not the same as disinfecting water or removing every contaminant. |
| Showerhead | Flow rating, spray pattern, fitting compatibility and a return policy. | A stronger-feeling spray does not establish better filtration. |
| Hardness test kit | A stated hardness range and clear units; follow the sampling instructions. | A general TDS meter is not a hardness-specific test. |
We’re planning a practical digital handbook: a testing checklist, questions for filter suppliers and a cartridge replacement tracker. It is not on sale yet. Subscribe for launch news; the free guides are available now.
