The AW-1901 Tankless RO system is a space-saving water purifier that offers two types of water: prefiltered and RO water. Moreover, it has dual handle faucets and brand-new insert type cartridges that feature a replacement light indicator and hassle-free, tool-less replacement.

The tankless design allows for direct water flow and the 500GPD RO membrane provides ten times the flow rate of traditional RO systems, so you can enjoy filtered water that removes bacteria, viruses, and heavy metals quickly.

The smart LCD display shows the TDS value and cartridge replacement status. Installation is quick and easy with insert type cartridges. The tankless design prevents bacterial growth. The system automatically flushes for 30 seconds when connected to electricity, saving water with a 1:2 waste to RO water ratio. It also has an integrated waterway design that prevents leakage.

The AW-1901 RO system has an integrated waterway design, which means that there are fewer connectors and less chance of water leakage. This is unlike traditional RO systems, which have many connectors that can be a source of leaks. The integrated waterway design also separates the water and electrical components, making the AW-1901 smaller than other RO systems.
