How we fund testing and independent reviews

This site participates in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by linking to Amazon.com.

When you click through our comparison links to Amazon and purchase a water filter dispenser, we may earn a small commission at no additional cost to you. These earnings directly fund our physical testing lab, water testing meters, and cartridge replacement tracking. However, financial partnerships never influence our micron ratings, cost-per-gallon calculations, or recommendation rankings.

We maintain strict editorial independence. If you have questions regarding our testing methodology or need to report a correction, reach out directly to the owner at [Owner Email].
