Advertising and affiliate links
Some outbound links on this website are affiliate advertisements. We may receive a commission if you follow a labelled link and make a qualifying purchase. The price you pay is set by the retailer; affiliate attribution does not add a separate charge from us.
We use the Awin affiliate network. For our Waterdrop UK links, the merchant is Waterdrop UK (advertiser ID 117649). Our pages label those links with “(Ad)”, and link elements use rel="sponsored nofollow".
How this affects our content
Commercial relationships can create incentives. To limit that conflict, we point out drawbacks, show ongoing costs, link to independent public-health guidance and describe circumstances when no filter is necessary. We do not accept payment to alter the factual information within these guides.
What happens when you click
Affiliate links redirect via Awin before taking you to the merchant. Awin and Waterdrop may process technical and attribution information and place cookies under their own policies. We don't receive your card details or individual order information from the retailer.
Current relationship
TapFilterChoice UK is operated by Ormaven Solutions s.r.o., not Waterdrop. Waterdrop product names are used only to identify the products discussed. We do not claim manufacturer endorsement.
