Reverse Osmosis Disinfection Water Purifier
Why should you use the Ousai disinfection and water purification machine?
To enjoy plenty of fresh, bottled water simply by turning on the tap at home, follow the “Bottled Drinking Purified Water Standard GB 19298,” and drink less pre‑packaged bottled water.
After being filtered by a water purifier, is the water really safe?
The biggest pain point of household membrane‑filtration water purifiers is the proliferation of harmful microorganisms.
While water purifiers remove sediment, rust, heavy metal ions, and other contaminants from water, they also eliminate disinfectants—such as chlorine—from tap water, leaving the purified water highly susceptible to bacterial contamination.
Water purifiers without a disinfection function are not suitable for direct drinking.


Equipped with hydrolyzed O 3 Antibacterial module
By controlling the O in the purified water 3 the generation rate and the purified water flow rate, ensuring that the water contains O 3 The effective concentration precisely eliminates microorganisms that proliferate in filtered water as well as on water-contact components such as pipes and valves, while ensuring the residual ozone level in the purified water. 3 The active ingredient ensures that the container is both filled and sterilized simultaneously, with no residual contamination.
