The Hard Water Filter is an optional pre-filter, designed to be placed outside any Echo Water™ Machine. The Hard Water Filter is installed directly onto the inlet source waterline. This filter decreases the total dissolved solids (TDS) in your water, prolonging the life of your Echo Water™ Machine. It is recommended that you replace the Hard Water Filter every six months for maximum efficiency.
This hard water filter should not be used with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the filter.
