How to Protect Your Family
Contaminants including Manganese, Aldicarb, Aluminum are best removed with a certified reverse osmosis system. Standard pitcher filters do not reliably remove many of these contaminants.
Echo RO System
Removes 99.9% of contaminants detected in your zip code's water supply. NSF/ANSI certified.

Is the water safe to drink in zip code 01094?
Water in 01094 (Worcester, Massachusetts) has 135 detected contaminants, of which 54 exceed EWG health guidelines. While it may meet EPA legal standards, health-focused guidelines are stricter. A certified reverse osmosis system provides the highest level of protection for your household.
What is the biggest water quality concern in 01094?
The most concerning contaminant detected in 01094 is Manganese — 8.4x the EWG health guideline. Reverse osmosis filtration is the most effective method for removing this contaminant and protecting your family.
What filter removes contaminants from 01094 water?
A certified reverse osmosis (RO) system is the most effective solution for removing the contaminants detected in 01094. Standard pitcher filters and carbon-only filters do not reliably remove many of the contaminants found in this area.
How was the water quality data for 01094 collected?
Data is sourced from EWG's Tap Water Database, which compiles results from water utility testing reports and EPA regulatory data. Levels shown represent the maximum detected across all water systems serving zip code 01094.
