Hydroviv custom-formulates filter media based on your local water quality report — founded by a PhD water scientist with strong E-E-A-T credibility.

Hydroviv: Custom-Formulated Filters From an Actual Water Scientist
Hydroviv occupies a unique position in the water filter market: their filters are custom-formulated based on your specific zip code's water quality report and source water analysis. Founded by Dr. Eric Roy (PhD, fluid dynamics), the company applies genuine water science to filter media selection rather than using a one-size-fits-all approach.
The approach is scientifically justified — different water sources have different contamination profiles, and optimizing filter media for local conditions can improve performance. The limitation is certification clarity. IAPMO lists a Hydroviv Drinking Water System under NSF/ANSI 42, 53 and 401. We could not confirm it matches the under-sink model we reviewed. That leaves the lead and PFAS certification for this model unconfirmed.
