Woongjin Coway demonstrates technology to make clean and tasty water with the “CIROO Tankless Water Purifier”. Woongjin Coway’s CIROO Tankless Water Purifier, which was awarded the ‘CES 2019 Innovation Award’, is an innovative product fitted with CIROO(Woongjin Coway Intensive Reverse Osmosis) 2.0 Filter, a culmination of our filter technology. The CIROO 2.0 Filter was jointly developed by world-renowned chemical materials company TORAY and applied a patent. The filter used the “Intensive Active Dense Layer”, which removes ion substances equivalent to the size of tens of thousandths of hair in thickness.

In addition, the new filter is six times larger than the existing CIROO filter increasing the amount of water filtered by 30 times, which means water can be provided without a holding tank, despite being an RO membrane filter. The filter also applies technology to prevent scale by self-cleaning thereby extending product lifespan. CIROO Tankless Water Purifier also achieves perfect tankless water in a hygienic way through the “water path drainage mode” and “automatic drainage system”. In the water path drainage mode, the product discharges remaining water inside the faucet to provide freshly purified water. With the automatic drainage system, the product also discharges all water from the purifier when water is not used for more than 24 hours.
