Under Sink Reverse Osmosis (RO) Water Filtration System with PP, Activated Carbon, and RO Membrane, 0.55 GPM Tankless Compact Design

This system produces water that tastes cleaner and looks more transparent in glassware. The combination of sediment filtration, carbon adsorption, and RO membrane works well. The compact design fits neatly under the sink, leaving space for storage. Filter changes are simple thanks to the tool-free cartridges. The PP filter lasts about a year, and the RO membrane has a long lifespan. Overall, it’s reliable for daily use.

This reverse osmosis system has noticeably improved our drinking water. The multi-stage filtration removes fine particles and reduces chlorine, while the RO membrane ensures high purity. The tankless design keeps water flowing instantly and saves cabinet space. The side-pull filter changes are one of the best parts—quick, tool‑free, and mess‑free. The 6000L membrane capacity helps reduce long-term maintenance. The build feels durable and leak-free. Consistent, clean water every day.

We chose this RO system for its tankless structure and long-life membrane. The 0.55 GPM flow is strong enough for a family kitchen, and the purified water tastes significantly better. The sediment and carbon filters remove odors and improve the clarity of beverages. The side-pull design makes maintenance easy even for someone with no plumbing experience. It runs quietly, and the absence of a tank means no stagnant water. The system fits well under our small sink.

This RO system gives clean, fresh water directly from the tap. The tankless design fits perfectly under our sink and the flow rate is strong enough for cooking and drinking.

The compact size saves space and the RO membrane keeps water clear. No leaks so far and maintenance has been easy.
