Water testing
Researched, not professional advice. Everything in this section is compiled from published standards, regulatory limits, manufacturer specifications and owner-review consensus, not hands-on testing. Nothing here diagnoses a water problem or says any product makes water safe to drink. Published figures and rules of thumb are labeled separately wherever both appear, and where a published figure does not exist we say so rather than estimating one. Test your water first, and treat bacteria, nitrate, lead, arsenic and PFAS as laboratory and professional territory rather than shopping decisions.
