• Up to 98+% PPM Rejection
• 1 membrane for stealth-RO150 and 2 membranes for the stealth-RO300
• Filters up to 150 GPD (gallons per day)
• Replace between 6 months to 2 years
• Compatible with Stealth 100/200 Model RO systems

RO output depends on the source water temperature. At 77°, the system should produce up to 100% of the rated output. As the temperature drops or increases, so does the output.

• Ultra‑Efficient Dry Membrane
• Reduces up to 95% of total dissolved solids (TDS)
• Filters up to 600 gallons per day (GPD)
• Replace between 6 months–2 years
• Replaces HL 22045
• Dimensions (H × W): 18.625" × 3.125"
• Weight: 2.275 lbs
   

Flow rates of RO systems are based on source water @ 65 psi / 77° / 500 ppm

There are two indications as to when to change your membranes

1. Test the RO and source/inlet water to see what percentage of the inlet water’s PPM the Stealth-RO150 is filtering out (rejection %). You should see up to 98% of the inlet PPMs being removed when the membrane is new. If the rejection % falls under an acceptable level (typically 90%) it’s time to change the membrane
2. When the flow rate of the product water slows down significantly. This can also happen if your pre-filters are clogged. If you change your pre-filters and the product water still flows slowly then it’s an indication you need a new membrane. When it doubt contact HydroLogic
