HALO 5 Whole Home Water Filter System

Cleaner, Healthier Water From the Moment It Enters Your Home

Looking for a dependable way to improve the quality of water in your home? The HALO 5 Whole House Water Filtration System is built to handle a wide range of water quality issues common in Southern California, from chlorine and sediment to harsh minerals that cause scale buildup. Instead of treating water at a single faucet, this system filters water right at the point of entry. Every tap, showerhead, appliance, and fixture in your home will benefit from cleaner, softer, better-tasting water.

How the HALO 5 System Works

The HALO 5 uses a multi-stage process to clean and condition your home’s water supply:

  • Sediment filtration removes dirt, debris, and larger particles as water enters your home.
  • Catalytic carbon filtration targets chlorine, chemicals, and organic compounds that affect taste and odor.
  • Conditioning media transforms hard minerals so they no longer cling to pipes, fixtures, or appliances—reducing scale without salt or ongoing maintenance.

Once installed, the HALO 5 system delivers consistently purified water without the need for messy salt bags, frequent cartridge changes, or ongoing maintenance.

Miguel was the technician that arrived within a few hours of my call to check on my water heater. He quickly assessed the situation and provided me options. I decided to go with a new water heater and he had it installed in just a couple hours. I was able to give my toddler a warm bath before bedtime!

On Sunday November 8 our water heater broke down and also had a bursted pipe. We called CastleWorks Water Heaters and they made sure we turned everything off properly and set up the water drain system correctly. Within 90 minutes a technician named Erik Vargas arrived, and let me tell You -- this Guy was fantastic! Erik went through all of our options and explained everything perfectly and then went to work installing our new Water Heater. After the technician Erik left our garage looking better than it ever has. CastleWorks gets a rating of💯👍🧑‍🔧 from us. W.P. Biagi

Why Homeowners Choose the HALO 5 System

A HALO 5 whole home filtration unit provides a long list of benefits designed to enhance not only your water, but your day-to-day living experience:

  • Great-tasting water throughout the home – Ideal for cooking, drinking, and bathing.

Understanding the HALO 5 Water Filtration System 

The HALO 5 is a whole-house water filtration solution designed to treat water at the point it enters your home. Its five-stage filtration process, combined with magnetic water conditioning technology, helps reduce contaminants, improve taste, and limit mineral buildup.

  • Stage One – Activated Carbon Filtration – Granular activated carbon removes chlorine, gases, pesticides, disinfectants, and heavy metals commonly found in municipal water.
  • Stage Two – Centaur® High-Activity Carbon – This stage further reduces chlorine and eliminates unpleasant taste and odor across varying water pH levels.
  • Stage Three – Filter-AG Plus® Media – A specialized filtration media that removes sediment more efficiently than standard granular materials.
  • Stage Four – Garnet Filtration Layer – The high-density garnet stage captures fine particles for enhanced clarity.
  • Stage Five – HALO Ion Water Conditioning – This inline conditioner treats water to help dissolve scale and reduce chlorine by-products throughout the plumbing system.

Additional technical specifications are available directly from HALO.
