GrowoniX EX200 Owners Manual GrowoniX EX200 Quick Start Guide GrowoniX Filter Replacement Guide GrowoniX Product MatrixRO water filtration with GrowoniX EX Series
The EX Series is efficiency at its best. We went back to the drawing board and asked the question, “How can we do the same thing we did with the GX Series, but do it at a special price point, one which opens the doors to everyone wishing to make purified water—without sacrificing the quality that is synonymous with the GrowoniX product line?” With the EX Series, we were able to strip out all the non- essential components, and leave in all the high quality parts found in the GX Series. We reduced the manufacturing cost and passed that savings along to our customers.
The EX Series is designed to flow between 4 and 17 GPH, (Gallons Per Hour) at almost 0 ppm RO water, with a 2:1 waste ratio. It’s affordable and durable, packed with features you would expect from a higher priced unit. It outflows all other RO’s in its class, with all the quality you would expect from a GrowoniX product.
For those who demand even more performance, the EX200 can be used with a booster pump, raising the system pressure to 80psi, increasing the gallon per day output.
The EX200 uses the High Flow Membrane. Less rejection than high rejection membranes, but with a much higher flow rate. Superior flow in cold water conditions as well. Our most popular membrane element.

KDF/Catalytic Carbon
For chlorine and chloramine 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.
Replacement & Upgraded Filters for EX200
*This filter is included. All other filters are available as substitutions and upgrades.
Carbon Filters

*CF-2510-GB
Green Coconut Carbon Block: NFS61 listed carbon filter manufactured with a patented process that greatly reduces greenhouse emissions—High flow with a low carbon footprint and superior chlorine removal.

CF-2510-CC
White Coconut Carbon Block: Ultra high purity coconut shell activated carbon filter. Superior chemical absorption and turbidity reduction. The unbeatable cost of performance value.

CF-2510-KDF
KDF85/Catalytic Carbon Filter: KDF85 Bacteriostatic media controls the growth of microorganisms. Good for water-soluble metals removal, chlorine, chloramine, and scale. Highly reactive catalytic carbon, extremely porous and long-lasting. Absolutely the best carbon filter available, a must for well water treatment, and the best option for removal of CHLORAMINE! Needs flushing upon initial startup and after filter changes to remove carbon fines and dust.
Sediment Filters

*SF-2510-SP
Spun polypropylene: A true multi-staged depth filter utilizing separate layers of micron filtration. Constructed spun polypropylene, these filters offer superior dirt holding capacity at an extremely economical price. They have more pressure drop than pleated filters. Great filter for changing frequently, especially in well water applications, or any situation where feed water is loaded with sediment.

SF-2510-PL
High flow pleated sediment filter: This is a washable, reusable, and durable sediment filter with a very low-pressure drop. Bacteria and chemical resistant. Great for high flow applications and extended time between filter changes.
Membrane Filters

*GXM-200-HF
High Flow Cold Water Membrane element: Less rejection than high rejection membranes, but with a much higher flow rate. Superior flow in cold water conditions as well. Our most popular membrane element.

GXM-150-HR
High Rejection Membrane element More rejection than high flow membranes, but with less flow rate. Great for ultra pure drinking water.
UV Water Filter

UV-1530
Stainless steel ultraviolet filtration to remove 99.9% of micro-organisms in your water supply. A must for well water treatment, whole house filter systems, or any time water will be stored. Flow rate of 1 GPM

GrowoniX EX200 - 200 GPD Reverse Osmosis Filtration System with KDF/CAT Premium Carbon Filter 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.
