NEW & IMPROVED! 4-Stage Undersink Filter Replacement Pack

Replacement Filter Pack for the 4-Stage Under Sink Filtration System

Our upgraded replacement filter pack is now tailored to provide advanced, natural filtration for both city and well water. These two new filters are non-customizable and offer the latest technology in contaminant reduction while maintaining beneficial minerals. For customers who prefer added minerals, an optional in-line mineralizer is available for purchase and can be easily installed after your system.

For those wishing to continue using the Aquametix or Cerametix filters, these are still available separately via the provided links below. For inquiries about the upgrades, feel free to use our chat feature or email us at info@greenfieldwater.com.

Filter Details

Stage 1: Ultra D Sub Micron Filter

• Captures particles down to submicron levels, effectively filtering out pathogens, sediment, and fine particulates.
• Reduces bacteria, viruses, and cysts like Giardia and Cryptosporidium for safer water.
• Provides pre-filtration to protect and extend the life of the second-stage filter.
• Designed for high performance with minimal pressure drop, ensuring a consistent flow.

Stage 2: NanoMetix Filter

• Combines advanced carbon and nanotechnology to reduce chloramines, lead, fluoride, VOCs, and emerging contaminants such as pharmaceutical residues.
• Proven to address PFAS, arsenic, and heavy metals, while also reducing cysts like Giardia and Cryptosporidium.
• Effectively handles contaminants previously targeted by pHA and KDF filters, including nitrates and chlorine.
• High surface area design ensures consistent performance with reliable chemical and contaminant reduction.
• Tested to NSF/ANSI Standard 53 (Cyst Reduction) and meets P231 Protocol for microbial reduction.

Additional Features

• Non-Customizable Filters: Simplified options suitable for both city and well water.
• Mineralizer Option: Adds essential minerals and balances pH, available separately for those who prefer it.

Note: Compatibility

This filter pack is compatible with both the old and updated versions of the 4-stage under sink system. The photo shows the larger copper vortexer lying horizontally on top of the two-housing filter in the updated model.

Legacy Filter Options (Purchased Separately at Provided Links)

• Cerametix: Removes E. coli, bacteria, and particulates down to 0.2 microns.
• Aquametix: Targets nitrates, fluorides, and broad-spectrum contaminants.

Can’t Find the Filters You’re Currently Using? Don’t Worry—We’ve Got You Covered!

The upgraded filters effectively address the same contaminants previously targeted by the pHA and KDF filters. This ensures you’re not missing out on any contaminant reduction, but rather benefiting from streamlined options with enhanced filtration performance.
