PureT (ST-34) Quick Change Encapsulated Twist-On Post-Filter GAC for E5HR0550 RO System
ST-34 Quick Change Encapsulated Post-Filter
The PureT ST-34 is a quick-change post-filter cartridge using granular activated carbon (GAC) to polish water after reverse osmosis membrane filtration. Encapsulated housing eliminates the need for separate filter housings and wrench tools. Designed specifically for integration with E5HR0550 RO systems and compatible models using twist-on post-filter connections.
Why the ST-34 Matters
Quick Change System
Twist-on, twist-off design allows cartridge replacement in seconds without tools, wrenches, or shutting down your entire system.
GAC Polishing
Granular activated carbon removes residual tastes, odors, and volatile organic compounds that may remain after membrane filtration.
Encapsulated Housing
Integrated filter and housing in one sealed unit reduces leak points and simplifies maintenance compared to traditional sump-style housings.
Exact Fit Engineering
Purpose-built for E5HR0550 systems with precise threading and flow path geometry for optimal contact time and performance.
System Integration
The ST-34 (also referenced as QCLS-PFGAC) is a direct replacement post-filter for the E5HR0550 reverse osmosis system and other PureT RO models using encapsulated quick-change post-filter stages. Installs in the final polishing position after the RO membrane and before the storage tank or dispensing faucet. Verify your system uses twist-on post-filter connections before ordering. Typical service life is 6-12 months depending on source water quality and daily production volume.
PureT filtration components are manufactured to OEM specifications for reliable performance in residential and light commercial reverse osmosis applications.
