  • Powerful 4-Stage Filtration: This under sink water filter system combines PP sediment, KDF, GAC, and a 0.01 micron ultrafiltration membrane to reduce chlorine, lead, rust, chloramine, hydrogen sulfide, and heavy metals—while preserving essential minerals for healthier, better-tasting water. Note: This is not a reverse osmosis system and does not reduce TDS.
  • High-Efficiency Ultrafiltration System: The 4-stage ultrafiltration water filter includes a 5-micron PP filter to capture larger particles like sand and dirt; a UF membrane for ultra-fine filtration; KDF/GAC filters for improved control of chemical contaminants such as chlorine by-products, hydrogen sulfide, and heavy metals; and an activated carbon block for final taste polishing.
  • Zero Waste, Compact Design: As a tankless under sink water filter, the CUA4-BLK produces no wastewater, requires no storage tank, and fits perfectly under any standard sink—ideal for use as a kitchen sink water filter, water filter for refrigerator, RV water filter, or any compact house water filter application.
  • Premium-Grade Components: Includes a lead-free faucet for clean drinking water. All filters, tubing, and water-contact components meet NSF/ANSI standards, ensuring safety and reliability in any home water filtration system.
  • Quick Installation & Filter Changes: With push-to-connect fittings, this under sink filter system for drinking water installs in minutes. Twist-on, twist-off cartridges allow tool-free filter replacement. Each filter lasts 6-12 months depending on water source and usage—perfect for a low-maintenance water filter system.
