Rhodi 0 Flow vs. Xero Pure: Which RODI System Is Best?
|Mohammed Sohag
The comparison between Rhodi Pro and Xero Pure primarily hinges on their flow requirements and maintenance features. While the Xero Pure is a legendary, durable 3-stage system known for its 12-year warranty and high-quality brass fittings, Rhodi 0 Flow systems are engineered to offer a higher standard 4-stage configuration. Rhodi 0 flow models often include an additional sediment pre-filter and a larger 10-inch DI housing as standard, providing better resin longevity and slightly higher flow rates (up to 0.90 gpm) at lower tap pressures compared to the base Xero model.
The Battle for the Best Pure Water Cart
Xero is a well known option in the space. Rhodi 0 Flow is newer, engineered with a 4 stage setup and built to give pros a high performance system at a more approachable price.
But which one actually saves you more money over a 5-year period? Let’s look under the hood
The Xero Pure: The Reliable Workhorse
The Xero Pure has been a best-seller for over a decade for a reason. It is a "no-frills" beast that prioritizes durability over gadgets.
- Durability: It features a steel frame and a stainless steel RO housing. Xero famously avoids plastic fittings, opting for more durable materials to prevent leaks.
- The "Pure" Philosophy: Xero’s design philosophy is "less is more." By removing extra gauges and valves, they aim to maximize flow directly to your pole.
- Warranty: They offer a massive 12-year warranty, which is one of the best in the industry.
The Rhodi 0 Flow: Built to Provide Value
Xero is a well known option. Rhodi 0 Flow is built to deliver the same 0 ppm results with professional grade components, but priced to make pure water more accessible. No corners were cut, we believe a dependable RO DI system should not be out of reach for aspiring or established window cleaners.
- 4-Stage as Standard: Unlike the base 3-stage units, the Rhodi 0 Flow includes both a sediment and carbon pre-filter before the water ever touches the RO membrane. This dual pre-filtration extends the life of your most expensive components.
- Superior Flow at Low Pressure: Rhodi 0 Flow systems are optimized for "low-tap-pressure" performance. While some systems struggle under 50 psi, the Rhodi Pro is configured to maintain a steady 0.35 to 0.600 gpm, allowing for higher reach without an external pump.
- Service-Friendly Layout: Rhodi 0 Flow is laid out to make routine maintenance straightforward. Filters are easy to access, swaps are quick, and it uses standard sizes you can buy from virtually any manufacturer, so you are never locked into a single source.
