Description
The membrane that does the real work in a Stealth-RO
This is the genuine replacement RO membrane for the Hydro-Logic Stealth-RO150 and Stealth-RO300 systems (compatible with Stealth 100/200 model units too), rejecting up to 98%+ of dissolved solids from your feed water. One membrane runs a Stealth-RO150; the RO300 uses two. As a membrane ages its rejection rate drops, so keeping an eye on PPM and swapping it in good time keeps your reservoir water genuinely clean rather than just filtered.
Key Benefits
- Up to 98%+ PPM rejection when new
- Rated up to 150 gallons per day output
- Direct fit for Stealth-RO150, Stealth-RO300 and Stealth 100/200 systems
- Output scales with source water temperature -- warmer water gives closer to full rated output
Falling RO output or rising PPM readings?
A tired membrane shows up two ways: the rejection percentage (how much of the inlet water's PPM it removes) drops below around 90%, or output flow slows noticeably. Testing your RO and source water PPM side by side tells you which stage needs attention -- if rejection has fallen off, it's the membrane, not the pre-filters.
How to Use
- Fits Stealth-RO150 (1 membrane) and Stealth-RO300 (2 membranes)
- Replace every 6 months to 2 years depending on use and source water quality
- Check rejection % periodically by comparing source and RO output PPM readings
