- You are setting up an entry-level filtration system because you need clean and consistent water without buying a commercial-scale unit.
- You are looking to reduce wasted water during standby periods because your current setup drains continuously while not in use.
- The 2-1 drain-to-product water ratio keeps the system running efficiently.
- The automatic shut-off valve halts the drain line whenever the product line is closed.
- A replaceable carbon pre-filter means you only need to swap the filter media itself rather than the entire housing.
- Growers who installed the compact unit say it easily fit into tight spaces where larger systems would not go
- Users who monitored the built-in pressure gauge say they could check system performance at a glance
HydroLogic MicRO 75GPD Reverse Osmosis System
Not every grower needs a high-volume RO setup like the HydroLogic Evolution-RO1000 — sometimes the goal is simply clean, consistent water without the footprint or cost of a commercial-scale system. The HydroLogic MicRO Reverse Osmosis System delivers exactly that: a compact, portable 75 GPD unit built as an economical entry point into reverse osmosis filtration, offering a smaller alternative to the Stealth-RO150.
The MicRO pairs a USA-made high-rejection RO membrane with a KDF85-infused carbon pre-filter, targeting chloramines and heavy metals before water ever reaches the membrane stage. A 2:1 drain-to-product water ratio, set by an external flow restrictor, keeps the system running efficiently, while an automatic shut-off valve (ASOV) halts the drain line whenever the product line is closed — cutting down on wasted water during standby periods.
Practical touches round out the design: a replaceable carbon pre-filter means you only need to swap the filter media itself rather than the entire housing, and an integrated pressure gauge with marked safe zones makes it easy to keep tabs on system performance at a glance.

Frequently Asked Questions
How much water does the MicRO produce?
The MicRO is rated for 75 gallons per day, making it an entry-level, economical option for smaller-scale reverse osmosis filtration.
What does the pre-filter remove from my water?
The carbon pre-filter includes KDF85 media, which targets chloramines and heavy metals before water reaches the RO membrane stage.
How efficient is the drain-to-product ratio?
The system runs a 2:1 drain-to-product water ratio, set by an external flow restrictor, for efficient operation relative to older or less efficient RO designs.
Does the system waste water when it's not in use?
No — the automatic shut-off valve (ASOV) closes the drain line whenever the product line is shut, so water isn't wasted during standby periods.
Do I need to replace the whole filter housing over time?
No — the carbon pre-filter is replaceable on its own, so you only need to swap the filter media rather than the entire housing, which is more affordable and generates less waste.
How is the MicRO mounted or set up?
It includes a metal bracket, so it can sit stable on a flat surface or be wall-mounted, along with a garden hose connector and 1/4" shut-off valve for straightforward hookup.
Is this system suitable for beginners?
Yes — the MicRO is positioned as an entry-level, economical RO solution, with a compact, portable design and a simple garden hose filter setup.
