Compatible with EcoWater model ERO-335
Made in the USA of Thin Film Composite (TFC) material
The KW-TFC membrane module is compatible with 3M Water Factory and EcoWater ERO-335 reverse osmosis (RO) drinking water systems. This membrane is constructed of thin film composite FDA approved material and is Made in the USA. The membrane is the component of a reverse osmosis system that separates Total Dissolved Solid (TDS) contaminants such as sodium, manganese, fluoride, nitrate, nitrite, lead and iron from the water molecule. When the membrane is performing efficiently these contaminants are reduced by 95%. For example, if the kitchen tap water TDS is 200 parts per million (ppm) the RO water TDS should be less 95% or less than 10 ppm. When the TDS number falls below a rejection level of 90% the membrane needs to be replaced. A handheld TDS testing meter can be purchased for approximately $15. If the reverse osmosis system can no longer keep up with household demand it may be that the membrane has lost efficiency and needs to be replaced. In any event do not exceed 5 years of membrane service life.
