How we write these guides
- Facts come from public agency pages that we open and check before use, and each guide ends with its sources.
- We do not make health claims, and we do not describe what a shower filter does beyond what our Quality page documents.
- Guides are general information. Water supplies and rules differ by country, so check with your local utility or authority.
