Two-stage filtration with precise filtration

• 0.5 micron two-stage filter preserves essential minerals while reducing contaminants
• Lead, chlorine, taste & odor, and particulates are targeted for clearer, fresher water

The system’s filtration elements are designed for easy replacement, so you replace only the core cartridge when needed, not the entire housing. This approach helps lower ongoing costs and reduces plastic waste over time.

Easy installation and broad compatibility

• 3/8" to 1/2" converter fittings allow direct attachment to most under-sink valves
• Twist-in design with built-in shut-off valve enables quick, tool-free filter changes

Whether you’re replacing old water filters or upgrading your kitchen’s hydration station, the MK99 integrates smoothly with standard plumbing and lets you control the flow with confidence.

Everyday benefits you can count on

• High flow rate suitable for drinking, cooking, washing produce, and rinsing dishes
• Direct connect setup minimizes clutter under the sink
