Affiliate Disclosure

Revenue is allowed. Editorial capture is not.

Some links on Water Filter Guide may become affiliate links. That does not change the standard we apply to the recommendation itself.

What this means

If a page includes an affiliate link, Water Filter Guide may earn a commission if a reader buys through that link. The buyer's price usually does not change.

What this does not mean

A commission does not guarantee a recommendation. We do not rank products because they pay more, and we do not hide downsides to protect a link.

How we keep it honest

We keep the useful parts visible: exact filter type, model-level claims, certification scope, replacement cost, installation constraints, and alternatives that may fit better.
