Hydrologic MicRO-75 Reverse Osmosis System is a portable reverse osmosis water purification system for hydroponic and horticultural water prep when you want cleaner source water. At the core is a reverse osmosis water filter membrane designed to remove up to 98%+ of most contaminants, creating purified water that’s better suited to consistent growing routines. The system also uses a replaceable carbon pre-filter designed for strong chlorine reduction, and it’s set up with kdf85 media for chloramine reduction and heavy metal reduction to help address common city-water treatment issues. This high-efficiency water purification system is built around practical, maintenance-friendly features rather than complicated extras. An integrated pressure gauge helps you monitor operation at a glance, while an automatic shut off valve supports cleaner system shut-down. An external flow restrictor is included to improve overall efficiency and help conserve water compared to similar RO filters. Hydrologic MicRO-75 Reverse Osmosis System is a good fit for growers who want a compact reverse osmosis system that supports cleaner water for reservoirs and general water preparation. It’s also well suited to gardeners dealing with fluctuating tap-water quality, especially where disinfectants and dissolved impurities can add unwanted variables. With its wall/floor mount bracket and garden hose connector, it’s designed to be straightforward to set up in typical grow spaces without turning water purification into a major project.
