HydroLogic - HLROMEM Stealth RO 100/200 Membrane

• 98+% PPM Rejection
• Rated at 2 GPM
• Filters up to 100 GPD (gallons per day)
• Replace between 6 months to 2 years

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

• 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-RO100 is filtering out (rejection %). You should see approximately 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

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