How the SMART Filtration Process Works

SMART Filtration Media

Water passes through a specialized blend of Eagle Redox Alloy®, ion exchange media, and activated carbon. This multi-stage media system is designed to help reduce chlorine, heavy metals, and other compounds that can affect taste and odor, while supporting overall water quality.

Carbon Block Filtration

A 5-micron carbon block helps reduce additional contaminants and captures fine particles that may be present in the water, including sediment and organic compounds that can impact clarity and taste.

Sediment Protection

A sediment pre-filter helps reduce sand, silt, dirt, and other particulate matter before water reaches the main filtration media. This helps protect the system and extend overall filter life.

Continuous Flow Through Multi-Stage Design

Water flows sequentially through each filtration stage, allowing each layer of media to perform a specific role in improving overall water quality.

Filter Life & Performance

The system is designed for long-term use, typically lasting 1–3 years depending on water quality and household usage. As the filter reaches capacity, flow will gradually slow, signaling replacement time.
