CuZn UC-100 Under Sink Water Filter – 1 Year Life, 10K Gallons, NSF 42/372

Crystal-clear water at your faucet, with a smart, compact setup

The CuZn UC-100 gives you a practical upgrade for daily hydration. This inline under-sink filter fits neatly out of sight, connects directly to your faucet, and requires no drilling. With a filtration life up to one year or 10,000 gallons (whichever comes first), it’s designed for low-maintenance, long-term use while keeping your tap water dependable and flavorful.

Designed for real-life use, the UC-100 emphasizes balance and reliability. You’ll notice water that feels crisper on the palate, with fewer off-notes from common tap-water impurities. This is achieved through a thoughtful three-stage filtration approach that targets contaminants at the source without stripping away minerals your water naturally contains.

Three-stage filtration for balanced purification

the UC-100 employs a precise blend of media to target common concerns while preserving minerals that contribute to taste and mouthfeel. Each stage works in concert to deliver water that tastes cleaner and reads as clearer in everyday use.

• Micro Sift Membranes: precise filtration that reduces impurities while keeping beneficial minerals.
• KDF-55: reduces certain metals and improves chlorine-related taste and odor.
• Coconut Shell Carbon: activated carbon that helps remove odors and refine flavor.

Independent testing supports reductions in PFAs, PFOS, lead, and chlorine, while NSF/ANSI 42 certified components help ensure consistent quality. Note that the unit does not reduce total dissolved solids (TDS).

Inline, DIY installation with no drilling

The UC-100 is designed for a straightforward upgrade to a kitchen or bathroom faucet. It connects inline for direct access to filtered water, fits in tight spaces, and includes all installation parts. A video guide is available to assist with setup and troubleshooting.

• Direct connect to a standard sink faucet
• No drilling required
• All installation parts included
• Video guide available

Long-lasting value and practical benefits

Smart design aims to minimize ongoing costs. With filtration life up to 10,000 gallons or one year, whichever comes first, you may experience fewer filter replacements. The system emphasizes flavor clarity and reliable performance without altering the core mineral content in a way that would surprise daily use. It’s a practical upgrade for households seeking consistent, clean-tasting tap water.

• One-year filtration life or up to 10,000 gallons
• Lower maintenance compared to frequent six-month filters
• Preserves beneficial minerals and does not lower overall TDS

Note: If you need more aggressive total dissolved solids reduction, consider additional filtration options beyond this unit.
