How the Ultrefiner II Premium Drinking Water System Operates:

ultrefiner_howStep 1:
Water from the inlet valve enters the system.

Step 2:
Water is forced through the pre-filter cartridge that reduces particles, chlorine, taste and odor.

Step 3:
Water then enters the reverse osmosis cartridge where it is filtered through a spiral wound, semi-permeable membrane.

Step 4:
The resulting highly filtered water enters a storage tank.

Step 5:
Your reverse osmosis water is finally filtered through the system post-filter and dispensed through a dedicated drinking water faucet.
