The Pure Blue H2O PBRO4-T is a 4-stage under-sink reverse osmosis water filtration system designed for whole-home drinking water purification. It uses a high-production 50 GPD (gallons per day) thin-film composite membrane to significantly reduce a wide range of contaminants from tap water.

The system reduces lead, chromium 6, fluoride, arsenic, radium 226/228, cysts, chlorine, taste, and odor. It is certified to NSF/ANSI Standards 58 and 372, ensuring both contaminant reduction performance and lead-free materials compliance. The patented Twist-Lock manifold design with valve-in-head technology allows for quick, tool-free filter changes without water spillage. An electronic monitor faucet indicator alerts you when filter replacement is needed.

Installation is straightforward and supported by detailed instruction manuals and step-by-step online video guides. The system connects to standard under-sink plumbing and includes all necessary hardware for a DIY installation.
