Long-lasting filtration you can rely on

When used with municipal water, this filter offers a maximum service life of up to 2 years or 19,000 gallons, depending on usage and water quality. That means less frequent replacements and steadier access to filtered water for daily needs.

Advanced multistage filtration

At the heart of this cartridge is a multistage filtration system. It helps reduce chlorine, along with taste and odor, and it can also cut down heavy metals, chemical impurities, and sediment. Third-party testing aligns with NSF/ANSI 53 for lead reduction, adding an additional layer of confidence for purified water from your tap.

• Chlorine and taste/odor reduction for cleaner-tasting water
• Heavy metals, chemical impurities, and sediment filtration for clearer water
• Lead reduction verified by third-party testing (NSF/ANSI 53)

Premium materials for safer, steady performance

The filtration membrane delivers 0.01 μm filtration accuracy, catching many fine particles. The activated carbon block uses natural coconut-shell material, and all components are BPA-free and lead-free to support reliable long-term use.

• 0.01 μm ultrafiltration membrane for fine particle removal
• Natural coconut-shell activated carbon for effective adsorption
• Lead-free and BPA-free construction for safer, durable use
