COMPATIBILITY & APPLICATIONS
System Integration
The ETRCHFM cartridge is engineered specifically for Watts E-Treat point-of-use ultrafiltration systems. The hollow fiber membrane design allows for high flow rates while maintaining submicron filtration efficiency, making it ideal for residential drinking water applications where bacteria and cyst removal is required without demineralizing the water. This cartridge installs quickly with a quarter-turn mechanism and does not require membrane flushing or tank storage like RO systems.
💧 Hollow fiber membranes filter mechanically, not chemically, so they retain beneficial minerals like calcium and magnesium while removing biological contaminants—a practical alternative to RO when TDS reduction is not needed.
