Which one should you choose?
Choose HydroLogic Evolution RO 1,200 GPD if
- You need high-volume water production for hydroponics or large households.
- You prefer a system with included custom KDF and catalytic carbon pre-filters.
- You have space for a wider unit with a 21-inch length.
Choose HydroLogic HLRO200 Stealth RO System if
- You require a compact, stealthy unit with a smaller footprint.
- You prioritize a lighter system that weighs only 11.5 pounds.
- You want reduced wastewater output compared to standard reverse osmosis systems.
Verdict: Choose the Evolution RO 1,200 GPD if you need maximum flow and specific pre-filtration for heavy-duty use. Select the HLRO200 Stealth if space is limited and you prefer a lighter, more compact design. Both systems effectively reduce contaminants, so your choice depends on capacity needs and installation constraints.
Capacity, Design, and Efficiency Comparison
Daily water capacity
The HydroLogic Evolution RO 1,200 GPD produces up to 1,000 gallons per day at standard line pressure. It also delivers 42 gallons per hour. This high output suits large hydroponic setups or high-demand commercial use. In contrast, the HydroLogic HLRO200 Stealth RO System produces up to 200 gallons per day. The HLRO200 is designed for lower volume needs. If you require rapid water production for extensive plant irrigation, the Evolution model provides significantly more volume. The Stealth model offers a modest 200 GPD output. This difference in capacity is the most critical factor for sizing your system correctly.
Physical dimensions
Size matters for under-sink or utility room placement. The Evolution RO 1,200 GPD measures 21 inches in length, 11 inches in width, and 11 inches in height. It occupies a wider footprint but is relatively low profile. The HLRO200 Stealth RO System is 6.1 inches long, 16.5 inches wide, and 18.8 inches high. The Stealth unit is taller and narrower, while the Evolution is longer and shorter. You must measure your available space carefully. The Stealth model may fit tighter vertical spaces, whereas the Evolution requires more linear counter or floor space. Neither unit lists a specific depth dimension other than length.
Weight and portability
Handling and installation weight differ between the two models. The HydroLogic Evolution RO 1,200 GPD weighs 15.3 pounds. The HydroLogic HLRO200 Stealth RO System weighs 11.5 pounds. The Stealth model is lighter, making it slightly easier to maneuver during installation or maintenance. The Evolution model is heavier, likely due to its larger housing and included components like two membranes and a pressure gauge. If you plan to move the unit frequently or have limited strength, the lighter Stealth system is easier to handle. Both are manageable for a single installer, but the weight difference is noticeable.
Filtration performance
Both systems use reverse osmosis to remove dissolved solids. The Evolution RO 1,200 GPD reduces total dissolved solids by 95% or more. It includes a custom KDF/catalytic carbon filter to reduce chlorine, chloramines, iron, sulfur, and heavy metals. The HLRO200 Stealth RO System removes 98% of chlorine and contaminants. The Stealth unit claims a higher percentage for chlorine and general contaminant removal. However, the Evolution model specifies its pre-filtration technology for heavy metals and sulfur, which the Stealth description does not explicitly mention. Both provide high-purity water, but the filtration mechanisms differ slightly in their described focus.
Water waste efficiency
Efficiency in water usage varies between the models. The Evolution RO 1,200 GPD features a 2:1 waste to product water ratio as standard. It includes an optional 1:1 ratio kit for improved efficiency. The HLRO200 Stealth RO System wastes approximately 25% less water than other reverse osmosis systems. The Stealth model does not list a specific ratio, but the 25% reduction claim suggests better efficiency than standard 3:1 or 4:1 systems. The Evolution model can achieve a 1:1 ratio with the optional kit, which is highly efficient. Without the kit, the Evolution uses more waste water. The Stealth model offers built-in efficiency without requiring optional parts.
Included components
What you get in the box affects installation convenience. The Evolution RO 1,200 GPD includes one KDF/catalytic carbon pre-filter, two high-flow reverse osmosis membranes, an inlet pressure gauge, a garden hose connector, an inline shut-off valve, 6 feet of white inlet line, 10 feet of blue purified water line, 10 feet of black drain line, and instructions. The HLRO200 Stealth RO System description does not list specific included accessories. It focuses on the filter and system output. The Evolution model provides a more comprehensive kit with multiple membranes and gauges, potentially reducing the need for separate purchases.
Which hydrologic model fits your needs
Users needing high volume for hydroponics
You need up to 1,000 gallons per day. This unit delivers 42 gallons per hour at standard pressure. It includes custom KDF and catalytic carbon filters to reduce chlorine, chloramines, iron, and heavy metals. The 2:1 waste ratio helps conserve water. This capacity supports large-scale hydroponic operations effectively.
Buyers wanting compact stealth installation
You prefer a smaller footprint. This model measures 16.5 inches wide and 18.8 inches tall. It weighs only 11.5 pounds. It produces 200 gallons per day with 98% contaminant removal. The design wastes 25% less water than other systems. It fits well in tighter spaces under sinks or in cabinets.
Those prioritizing specific filtration components
You value detailed pre-filtration specs. This system includes a KDF/catalytic carbon pre-filter. It reduces total dissolved solids by over 95%. It comes with two high-flow membranes and an inline shut-off valve. The included garden hose connector and inlet pressure gauge add practical utility for monitoring and connecting your water source.
