What customers say
Customers overwhelmingly express high satisfaction with the Waterdrop X Series Dual Flow Reverse Osmosis System, X8-PRO, frequently highlighting its exceptional water quality as a standout feature. The taste of the purified water is consistently described as clean, crisp, and superior to bottled water, making it a game-changer for many households. A significant advantage lauded by users is the innovative dual-flow design, which provides both ultra-pure RO water and a filtered stream for general use, effectively extending the life of the RO membrane and offering practical convenience. This feature is particularly appreciated for tasks like washing produce or filling larger containers where RO purity isn't strictly necessary. Installation is another area where the X8-PRO receives strong positive feedback. Many users, even those with limited plumbing experience, found the setup process surprisingly straightforward and well-documented, often citing the clear instructions and included tools as helpful. The tankless design is a major draw, freeing up valuable under-sink cabinet space, a common pain point with traditional RO systems. While the initial investment is noted by some, the perceived value for money is high, given the advanced features, water quality, and the convenience of the dual-flow system. Minor points of feedback occasionally touch on the operational noise, which is typical for RO systems but generally considered acceptable, and the ongoing cost of filter replacements, though most find it reasonable for the performance delivered. Overall, the X8-PRO is celebrated for its blend of advanced technology, user-friendly design, and superior water purification, solidifying its reputation as a top-tier choice for home water filtration.
Know before you buy
The system measures 18.2 x 6.25 x 16.72 inches. Because it features a tankless design, it occupies significantly less space than traditional RO systems, leaving more room for your other under-sink storage.
A 2:1 ratio is highly efficient for a reverse osmosis system, meaning for every two cups of pure water produced, only one cup is sent to the drain. This is a significant improvement over older systems that often waste much more water during the filtration process.
The system is designed for tool-free installation, making it straightforward to set up. The smart faucet connects directly to the system to provide real-time TDS and filter life monitoring without requiring complex wiring.
The main RO filter is rated for a 24-month lifespan, or approximately 2,200 gallons of water. The system includes a built-in filter change indicator on the faucet, so you will receive a clear alert when it is time for a replacement.
The 9-stage process is designed to effectively reduce common contaminants including lead, chlorine, and sediment. It is certified to NSF/ANSI 42 standards, ensuring reliable performance for cleaner, better-tasting water.
Yes, because the X8-PRO uses an electric pump to achieve its 800 GPD flow rate and power the smart monitoring features, you will need access to a standard electrical outlet under your sink.
