About This
- SUPERIOR PERFORMANCE: The advance 4-stage design, which includes both Ultrafiltration and KDF/GAC stages, removes up to 99% of chlorine and chlorine treatment by-products, lead, and much more, while retaining minerals. Noted: This system is NOT a Reverse Osmosis water filtration system and does NOT lower TDS.
- 4-Stage ULTRAFILTRATION SYSTEM: PP Sediment Filter (5 microns) removes larger particles like rust, sand, dirt. Ultrafiltration membrane contains hollow fiber membrane technology with a pore size of just 0.01 microns. KDF and GAC Filter provides much better control of particularly problematic contaminants including chloramine, hydrogen sulfide, heavy metals, and other compounds. Fine Activated Carbon Filter provides final polishing.
- SIMPLE AND FLEXIBLE: NO WASTE WATER and No storage water tank required. The CU-A4 provides highly effective water filtration for any number of clean water needs - at the sink, in the refrigerator, for coffee makers and more.
- FEATURES: Come with premium brushed nickel finish drinking water faucet. All filters, tubing and other water-contacting parts are manufactured to comply strictly with NSF/ANSI standards for safety and water quality.
- EASY-TO-INSTALL AND REPLACE FILTER: Push to connect fittings for simplify setup. Filter replacement are designed for ease. No need to disconnect hoses or water lines. Just Twist On / Twist Off filter cartridges make changing filters a snap. Filter life: 6 -12 months, depending on your source water and usage.
