What to write about

• Corrections. Include the page link, the number or claim, and your source. We check every correction against the source.
• Questions about a guide. We read every message, though we can’t design a system for your home or give advice for a specific health situation.
• Brands and PR. You’re welcome to send manuals, spec sheets and certification details. We don’t accept payment for placement or reviews.

Replies can take a few days. For urgent water quality or health concerns, contact your local health department or a licensed water treatment professional.
