ZeroWater ZR-004 Four-Pack Replacement Filter Cartridges – 4 Count (Pack of 1) | Basic Pack

Pure, better-tasting water starts with the right filter

Introducing the ZeroWater ZR-004 four-pack replacement cartridges. These filters are designed to fit every ZeroWater pitcher and dispenser, from the smallest model to the largest. Rather than relying on carbon filtering alone, this system uses a thoughtful multi-stage approach to help deliver water that tastes crisper and cleaner right from your glass.

At the heart of ZeroWater is a five-stage filtration system with ion exchange technology. This combination works together to reduce dissolved solids and common impurities that can affect flavor and clarity. Independent lab testing highlights the strength of this filtration by removing a high percentage of total dissolved solids, while NSF certification confirms performance in reducing lead and other metals.

What you’ll notice in daily use is a refreshing, clean-tasting result with less of the mineral aftertaste some filters leave behind. The 4-pack format means you can rotate cartridges for consistent results, whether you’re stocking a home setup, an office, or a shared kitchen. And since these filters are compatible with a wide range of ZeroWater products, you can rely on a single filtration system for different needs over time.
