## What this site is
Mr Water Geek explains what is in home tap water and how to evaluate filtration —
by chemistry, certification (NSF/ANSI), and category. We do not lab-test
products. Guidance is reader-funded; affiliate links are disclosed.

## Methodology
We match filtration technologies and certifications to contaminant types. Key
claims are sourced to primary references: EPA, CDC, NIH, NSF, ATSDR, and
peer-reviewed research.

## Author
Shashank Varma — Founder & Engineer. 9 years at Kohler (water filtration);
ex-Apple (hardware).
