Affiliate disclosure

Today, the retailer buttons on FilterDue ("Check price", "Shop") are ordinary links to retailer product or search pages. They are not affiliate links, and we earn nothing from them.

We plan to apply to affiliate programs such as Amazon Associates, FilterBuy and FridgeFilters.com. If approved, some of these links will become affiliate links, and FilterDue may then earn a commission on qualifying purchases at no extra cost to you. As an Amazon Associate, FilterDue would earn from qualifying purchases. We will update this page when that happens, and affiliate links will be marked rel="sponsored".

Commissions will never change the facts we publish. Part numbers, intervals and certifications come from manufacturers and NSF public listings, cited on every page. Aftermarket alternatives are listed because they are certified, not because they pay.
