Affiliate disclosure

Clean Water Guide is reader-supported. Some of the links on this site are affiliate links. If you click one and buy a product, we may earn a commission — at no extra cost to you. The price you pay is exactly the same.

In line with the UK Advertising Standards Authority (ASA) and CAP Code, we disclose this clearly. You'll find a short disclosure near the top of every page that contains affiliate links, as well as this dedicated page.

Our promise

Affiliate commissions do not influence our recommendations. We decide our rankings using the research method set out on our How we research page — before any commercial consideration. Where a cheaper product is the better choice, we say so, even if it earns us less. We also link directly to brands first (rather than third-party marketplaces) where doing so is better for you.
