The GX150-HF with a single GrowoniX Ultra High Rejection membrane out-performs all other systems in the same class that utilize two membranes. When GrowoniX developed the GX150-HF, they decided to pack all the high end features into a tight efficient RO unit. GrowoniX engineered a 50% increase in water production over traditional RO systems, lowered the waste ratio to 2:1, and still offered it to you for the same price point of an entry level RO filter. We topped it all off with a 2 stainless steel liquid-filled pressure gauge, never before seen in a filter this size, and integrated it into our patented GX Series bracketing system. A manual flush valve allows you to clean the membrane, purging out pollutants that could otherwise add buildup to the system.
GX200 = High Flow membrane for superior water production, a bit more TDS. 200 GPD. Click here to learn more.
GX150-HR = Ultra High Rejection membrane for the purest of water, a little less flow. 150 GPD.
- Growonix GX150-HR Systems Features:
- Ultra High Rejection membrane element
- 2:1 system ratio - The most efficient in the industry!
- Electrogalvanized powder coated steel brackets
- Membrane flush kit
- 2.5" stainless steel liquid filled gauges
- One Eco Green Coconut Carbon filter rated for 16,000 gallons for chlorine reduction. Chloramine removal requires KDF85/CAT carbon filter
- High Flow pleated sediment filter, completely wash-able and reusable
- Auto Shutoff Valve: for positive automatic shutoff when using a float valve
- No additional pre-filters needed!
Optional KDF85 Carbon Filter Upgrade:
For chlorine and chloramines reduction for city water. Also for well water for iron, hydrogen sulfide, and heavy metals reduction. Will last TWO TIMES AS LONG as the standard green carbon filter. Prolongs the life of the membranes. Reduces chloramines, chlorine, iron, sulfur and heavy metals. Bacteriostatic qualities do not allow microbes to breed in filter.
Optional Accessories for GX150 Systems:
BP-1530 Booster Pump to raise the input feed-water pressure from zero to 80psi-even pumps water from a rain barrel through the system.
The strategy behind the GX Series is simply to make the highest quality, most efficient water filter, tuned specifically to meet the rigors of the industry. Each filter system is designed, hand built, and tested right here in the United States, using American made, top-of-the-line fittings and tubing. All components are housed in steel powder-coated brackets fabricated in sunny Los Angeles, California.

GrowoniX GX150-HR - 150 GPD Reverse Osmosis Filtration System Questions & Answers
WATER TEMPERATURE FAQ's
How does water temperature effect flow rates through RO filters?
Between 77° and 50° water system production declines by 50%, as cold water is more dense, more viscous, and more difficult to move through the membranes.
What can be done to combat the effects of cold water on RO membranes?
Increasing the water pressure with a booster pump. Increasing the feed water temperature, which some people do by mixing warm and cold water from a diverter valve.
SYSTEM RATIOS FAQ's
Does the system ratio (waste ratio) change over time?
System ratios can change over time if the flow restrictor starts clogging due to hard feed water conditions.
Does the system ratio change with water temperature?
System ratios (waste ratios) can drift with cold feed water. Water travels the path of least resistance — the drain line! It’s important to check the system ratio during the winter months and adjust if necessary.
How can the system ratio be adjusted?
System ratios can be tuned with a ball valve or Flow Box. Never go lower than the system was intended for.
WATER PRESSURE FAQ's
How much water pressure is needed to run an RO system properly?
RO membranes require 40 psi of incoming pressure to produce even a drop of water except our GXM200-HF which requires only 20PSI. The only membrane on the planet that can do this.
What’s the maximum feed water pressure that an RO system should run on?
Incoming feed water pressure on all water filters, always and everywhere, should be no more than 80psi. Plastic filter housings cannot handle more pressure.
WELL WATER FAQ's
Can all GrowoniX water filters be used with well water?
Well water is generally too dirty for small RO membranes (100GPD through 400GPD systems). The large 4” membranes of the bigger systems (600GPD and larger) are recommended for well water treatment, unless the water demand is really low.
Are there any special filters needed to treat well water?
KDF85/ catalytic carbon filters are a must for well water treatment. This premium catalytic carbon filter with a bed of KDF85 media can reduce iron, hydrogen sulfide, heavy metals, and bacteria—all things that wreak havoc on RO components—especially membranes. Other consideration for special filters can only be deduced with a laboratory water analysis.
Does GrowoniX help with well water analysis?
They do. Just send Growonix your water analysis and they will look at it for free. If you don’t have a recent analysis, you can either use a local water lab, or purchase a test kit through GrowoniX send it off to our partner lab.
GrowoniX GX150-HR - 150 GPD Reverse Osmosis Filtration System Reviews
- Excellent, efficient little unit
I routinely get 10-20 ppm water out of this unit (starting with 200-350 ppm city water), which makes my rain-forest, higher-elevation orchids very happy. Its production rate and efficiency meet specifications. Last winter I added a booster pump since when incoming water is cold production does diminish, and that worked very well.
