The Echo® 9 Replacement Filter is the official replacement filter for the Echo® 9 hydrogen machines:
• Echo® 9 Ultra H2

This filter is used to remineralize your water if you happen to have a reverse osmosis system or filtration on the the whole home or if your water naturally is low in total conductible dissolved solids.
This filter is one of our proprietary filters that removes chlorine, chloramines, pharmaceutical drugs, water soluble metals, bacteria, algae, pesticides, and other chemicals found in your water.
