HALO 5 Water Filtration System Overview

The HALO 5 is a point-of-entry, whole-house water filtration system engineered to treat all water entering a residential or commercial property. Rather than filtering water at individual fixtures, the system is installed directly on the main water line, allowing it to address water quality concerns at the source. By combining five distinct filtration stages with advanced magnetic water conditioning technology, the HALO 5 is designed to improve water clarity, taste, and overall performance while helping reduce mineral scale throughout plumbing systems.

Five-Stage Filtration Process

The HALO 5 utilizes a layered filtration approach, with each stage targeting specific contaminants and water quality issues:

Granular Activated Carbon (GAC) – The initial filtration stage reduces chlorine, chloramines, volatile organic compounds (VOCs), and common chemical disinfectants found in municipal water supplies. This step plays a critical role in improving water taste and reducing odors.
Centaur® High-Activity Carbon (HAC) – Designed for consistent performance across varying pH levels, this media further reduces chlorine while removing compounds that contribute to unpleasant taste and smell.
Filter-AG Plus® Sediment Media – This non-hydrous filtration media removes suspended solids such as sand, rust, dirt, and sediment more efficiently than traditional granular filters, helping protect downstream plumbing components.
High-Density Garnet Filter Media – As a dense filtration layer, garnet media captures fine particulate matter that may bypass earlier stages, improving overall water clarity and system effectiveness.
HALO Ion Inline Water Conditioner – The final stage uses magnetic conditioning technology to alter the physical behavior of dissolved minerals. This process helps limit scale formation, reduce chlorine by-products, and support the longevity of plumbing systems and appliances.

System Specifications & Performance

The HALO 5 is engineered for long-term performance with minimal homeowner involvement. The system does not require routine maintenance or filter replacements, making it a low-maintenance water treatment solution. For an average household of four using approximately 146,000 gallons of water annually, the filtration media typically lasts between 8 and 10 years.

The HALO 5 system includes a lifetime limited warranty covering major components, including the tank, control head, and inline ion conditioner.

In addition to residential applications, the system is widely used in commercial environments such as hospitality, healthcare, food service, irrigation systems, and office buildings where consistent water quality is essential.

Whole-Home & Appliance Protection Benefits

Because all incoming water is treated at the point of entry, the HALO 5 helps protect plumbing infrastructure and water-using appliances from sediment accumulation, chlorine exposure, and mineral scale buildup. Over time, this can contribute to improved appliance efficiency, reduced maintenance needs, and extended equipment lifespan for water heaters, dishwashers, washing machines, coffee makers, and ice machines.

Water Quality & Health Considerations

Mineral-rich or untreated water may contribute to dry skin, hair damage, and irritation for individuals with sensitivities (National Eczema Association).

Excessive fluoride exposure has been associated with dental enamel changes and skeletal conditions when present at elevated levels.

PFAS—often referred to as “forever chemicals”—are persistent compounds linked to hormone disruption, immune response changes, cholesterol levels, and pregnancy-related health risks.

Additionally, taste and odor issues in tap water are commonly caused by organic matter, metals from aging plumbing, or elevated mineral content.

A whole-house filtration system like the HALO 5 addresses these concerns by treating water before it reaches any fixture in the home.
