Hydro-Logic Stealth RO/Small Boy Green - Coconut Carbon Filter
Green Coconut Carbon Filters are the carbon block pre-filter that will reduce chlorine, organic chemicals, mercury, lead, PBCs, sulfur and heavy metals. #741604 is 20 in x 4.5 in. #728845 is 20 in x 2.5 in. #741646 is 10 in x 2.5 in. #741656 is 20 in x 2.75 in.
Hydro-Logic Stealth RO150/300 RO Membrane
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.

Hydro-Logic Pressure Booster Pump for Stealth
This pump is designed to be installed before the Stealth RO to boost the inlet pressure. Wells and low pressure (below 40 PSI) water sources can benefit greatly from this pump. It boosts the pressure significantly, allowing the Stealth RO to run with higher flow and more efficiency while having better TDS removal. The pump is designed for long service life and runs very quietly. Comes with a high pressure switch and operates at 110V.
