Hydro-Logic Stealth RO150/300 RO Membrane

Q102418

Replace membranes when product water decreases and/or ppm increase. Merlin Garden Pro and Evolution RO1000 membranes reduce 94%+ of total dissolved solids. Stealth RO100/200, Stealth RO150/300 and microRO-75 membranes reduces 98%+ of total dissolved solids. The Evolution RO1000 and Merlin Garden Pro systems need two (2) membranes. For all membranes, 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.
