How an Ultrefiner Elite Drinking Water System Works
- Unfiltered water enters the system from the inlet valve.
- Water flows through the pre-filter which reduces particles and chlorine taste and odor.
- Water then enters the Ultrefiner Elite reverse osmosis stage where it is flittered through a spiral wound, permeable membrane.
- The resulting highly filtered water enters a storage tank.
- Your reverse osmosis water is finally filtered through the post-filter and delivered through a dedicated drinking water faucet to enjoy cleaner, better-tasting water.
