Affiliate Disclosure

Last updated 2026-10-19T00:00:00.000Z

HardWaterHero is reader-supported. Some links on this site go through a short redirect at hardwaterhero.com/go/....

Right now we are not a member of any affiliate program. Every /go/ link currently sends you straight to the official brand or retailer page, with no tracking codes, and we earn nothing from it.

In the future, some of these links may become affiliate links (for example with US Water Systems). If you buy through one of them, we may earn a commission at no extra cost to you. When that happens we will update this page and mark those links accordingly.

Commissions never decide our numbers. Calculator results, specs, prices, and certification findings come from the cited official sources, and we show the math so you can check it. We don’t accept payment for placement or reviews. We have not tested products hands-on and never claim to.

This disclosure follows the U.S. Federal Trade Commission’s Endorsement Guides.
