Heavy Metals Defense Pack - Whole House System Refill Set

The Heavy Metals Defense Refill Pack is designed for homes looking to target contaminants such as iron, copper, chlorine, and other heavy metals commonly found in municipal and groundwater supplies.

The system uses a three-stage filtration process that protects the system from sediment while delivering targeted contaminant reduction and final-stage PFAS protection.

This refill pack contains:

• Stage 1 – Sediment Guard Filter
• Stage 2 – Heavy Metals Defense Filter
• Stage 3 – PFOS Ultra Filter

Together these filters create a layered defense system designed to keep your Santé Smart Whole-Home System operating at peak performance.

Complete 3-Stage Replacement

Includes all three replacement cartridges required for the Santé Smart Whole-Home Filtration System.

Heavy Metal Reduction

Designed to reduce contaminants such as iron, copper, and other metals commonly found in residential water supplies.

PFAS Protection

Final-stage PFOS filtration helps reduce PFOS, PFOA, and related PFAS compounds down to extremely low levels.

High-Flow Whole-Home Design

Engineered for whole-home flow rates to support showers, appliances, and household water demand without restricting pressure.

NSF Certified Components

Filtration components independently certified to NSF standards for material safety and contaminant reduction.

Made in the USA

Filters and filtration media are manufactured in the United States using domestically sourced materials.

Stage 1 — Sediment Guard Filter

The Sediment Guard Filter captures large particles and sediment before they reach downstream filtration stages.

Constructed from durable polypropylene with a radial pleat design, this high-flow filter traps both large and small particulates while maintaining strong water pressure throughout the home.

Benefits include:

• Protects downstream filtration media
• Prevents premature clogging
• Maintains consistent system flow
• Extends overall filter performance

This stage is NSF 42 certified and designed specifically for whole-home filtration applications.

Stage 2 — Heavy Metals Defense Filter

Every Santé Smart System refill pack begins with a catalytic carbon foundation, the core filtration standard used across all configurations.

In the Heavy Metals Defense configuration, this catalytic carbon base is enhanced with KDF-85 media and advanced metal-reduction technology designed to target contaminants commonly associated with aging infrastructure and groundwater sources.

This stage focuses on fine-particle filtration and heavy metal reduction while maintaining high-flow performance, making it particularly effective for homes where lead, copper, or legacy plumbing materials may be a concern.

This filtration stage helps reduce:

• Iron
• Copper
• Heavy metal contaminants
• Chlorine taste and odor
• Oxidation buildup and mineral deposits

Stage 3 — PFOS Ultra Filter

The PFOS Ultra filter provides final-stage protection against PFAS compounds, including PFOS, PFOA, and GenX.

Constructed with high-density acid-washed coal-based carbon infused with specialized media, this filter is engineered to remove PFOS compounds down to extremely low concentrations.

This stage is NSF 42 and NSF 372 certified and acts as the final safeguard before water enters your home’s plumbing system.

These replacement cartridges are designed specifically for the Santé Smart Whole-Home Filtration System and install directly into the system housing during routine maintenance.

Most households replace filters approximately every 6 months, though replacement timing may vary depending on water usage and local water quality.

Homeowners using the optional smart monitoring system will receive alerts when filter lifespan approaches replacement levels.
