micRO-75 from Hydro Logic

The micRO75 is a customized Reverse Osmosis water filter that is capable of removing up to 98%+ of most contaminants. The system is designed for use with hydroponic or horticulture applications, but can also be used effectively in a variety of other setting as well. The filter is built to give the maximum amount of flow from the membrane while sending less waste water to drain, compare to similar RO filters.


An economical, entry level, micro-sized, portable reverse osmosis system, 75 gallons per day solution.

Includes KDF/carbon filter and 75 GPD membrane. Also comes with garden hose connector, ¼" shut off valve, and pressure gauge. Features 2:1 drain to product water ratio for maximum efficiency.

The filter has a rated life of approximately 1,000 gallons of Reverse Osmosis product water. The membrane usually lasts 6-18 months depending on the quality of your tap water and how often you change the carbon/KDF pre-filter. Additional pre-filtration may be necessary depending on the quality of your tap water.

De-Ionization for micRO 75

This de-ionization filter is designed to serve as a post, polishing stage for any Reverse Osmosis system. After an RO system, the product water may contain trace amounts of nitrates, phosphates, and silicates as well other total dissolved solids (TDS). Certain applications such as aquarium, medical, manufacturing and others require 99.99% ultra pure, 0 PPM water. This DI filter will remove any leftover contaminants giving you the purest H2O available.
