Accuracy matters more than a longer article.
Our purpose is to help readers understand a real problem, act safely and evaluate equipment without confusing marketing claims with evidence.
Evidence and sourcing
We prioritize government drinking-water guidance, technical manufacturer documentation, recognized standards and clearly identified third-party references. We explain when a conclusion is conditional on local water chemistry or system design.
Reviews and product claims
We do not present manufacturer specifications as hands-on tests. We clearly distinguish technical comparison, desk research and firsthand testing if independent testing is actually completed and documented.
Corrections and updates
When equipment specifications, safety guidance or source material changes, we aim to revise affected pages and correct errors. Publication and update dates should be visible on individual articles.
Commercial independence
Some pages may include affiliate links, but compensation does not change the technical safety requirements or justify recommending an unsuitable product.
