How to Protect Your Family
Contaminants including 1,2,3-Trichloropropane, 1,4-Dioxane, 6:2 Fluorotelomer Sulfonic Acid (6:2 FTSA) 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 00930?
Water in 00930 (La Verne, California) has 121 detected contaminants, of which 36 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 00930?
The most concerning contaminant detected in 00930 is 1,2,3-Trichloropropane — 24.0x 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 00930 water?
A certified reverse osmosis (RO) system is the most effective solution for removing the contaminants detected in 00930. 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 00930 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 00930.
