The PureT ST-05 is a quick-change encapsulated sediment filter engineered for the E5HR0550 reverse osmosis system, delivering 5-micron filtration in a tool-free twist-on design. This first-stage cartridge traps sediment, rust, and particulate before they reach your membrane, extending system life and protecting downstream components.

COMPATIBILITY & APPLICATIONS
System Integration
The ST-05 is designed specifically for the E5HR0550 reverse osmosis system and other PureT quick-change housings. This encapsulated design eliminates the need for separate filter housings and wrench tools—just twist off the old cartridge and twist on the new one. Ideal for municipal and well water applications where sediment, silt, sand, and rust particles need to be removed before reaching the RO membrane. Use this filter as your first line of defense in any multi-stage water purification system.
💧 Replace your sediment filter before you replace your membrane. A clogged pre-filter is cheaper to swap than a fouled RO membrane, and regular changes keep your system running at full pressure and efficiency.
