Affiliate Disclosure
Last updated: April 2026
Our Relationship With Product Brands
HardWaterHQ participates in affiliate marketing programs, including the Amazon Associates Program and direct affiliate programs with water filtration brands. This means that when you click certain product links on this site and make a qualifying purchase, HardWaterHQ may earn a small commission — at no extra cost to you.
The price you pay for any product is exactly the same whether you click through our link or navigate directly to the retailer. Affiliate commissions are paid by the retailer or brand, not by the consumer.
Which Links Are Affiliate Links?
We mark affiliate links and product placements with a disclosure notice near the content where they appear (for example, ""-style markers during our build phase become clearly labeled product recommendations in the final guide). We strive to make it clear when a link may result in compensation.
Not all product links on HardWaterHQ are affiliate links. We frequently link to products, resources, and tools without any affiliate relationship when they are the best reference for the topic at hand.
How This Affects Our Editorial Recommendations
It doesn't. Our editorial process determines which products and solutions are recommended first — based on effectiveness, value, and relevance to the problem being discussed. We do not accept payment for editorial placement, and affiliate relationships do not influence which products we recommend or how we review them.
If a product we are affiliated with is not the best option for a reader's situation, we will say so and recommend a better alternative, even if that alternative has no affiliate relationship with us.
We are committed to giving homeowners accurate, useful information about their water quality. Misleading readers to earn a commission would undermine the entire purpose of this site.
Amazon Associates Disclosure
HardWaterHQ is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate, we earn from qualifying purchases.
FTC Compliance
This disclosure is made in accordance with the Federal Trade Commission's guidelines on endorsements and testimonials in advertising (16 CFR Part 255). We believe in full transparency with our readers about any financial relationships that may exist between HardWaterHQ and the brands or products mentioned on this site.
