    • 98+% PPM Rejection
    • 1 membrane for stealth-RO150 and 2 membranesĀ for the stealth-RO300
    • Filters up to 150 GPD (gallons per day)
    • Replace between 6 months to 2 years

    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 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
