O. Smith AR75-U2 Water Purifier
- Slim Design: With an ultra-thin profile of just 161 mm, this design maximizes kitchen space efficiency for your home.
- UV Sterilization: The UV lamp acts as a second line of defense after the RO-SideStream membrane, eliminating 99.9% of viruses, bacteria, molds, and other contaminants to ensure pure water.
- Electronic Faucet: Features an electronic faucet with a filter status display, alerting you when it’s time to replace the filter.
- RO-Side Stream Technology: Enhances purification by increasing the amount of pure water by 66%, reducing wastewater by 56%, and extending the membrane’s lifespan by 1.5 times compared to standard RO membranes.
RO-Side Stream Technology (U.S. Patent)
The RO-SideStream membrane is a breakthrough invention by A. O. Smith, patented in the U.S. (patent US8,337,698 B2). It improves efficiency, increases pure water production by 66%, reduces wastewater by 56%, uniquely maintains a 1:1 pure to waste water ratio, and extends filter lifespan by 1.5 times compared to conventional RO membranes. It removes 99.9% of heavy metals (arsenic, lead, mercury) and harmful bacteria.
