HALO 5 Whole Home Water Filter System

Purified Water for Every Tap in Your Home

Imagine turning on any faucet in your home and knowing the water flowing out is clean, refreshing, and safe. With the HALO 5 Whole House Water Filtration System, that peace of mind becomes reality. Installed at the main point of entry, the HALO 5 treats every drop of water entering your home—so whether you’re drinking from the kitchen sink, showering, or running the dishwasher, you’ll enjoy filtered, great-tasting water.

Why Choose the HALO 5 Water Filtration System?


The HALO 5 is one of the most advanced home water treatment systems available. Unlike standard filters that only target specific concerns, the HALO 5 uses a multi-stage filtration process to address a wide range of water problems at once.

It reduces or removes:

  • Chlorine and chloramines that cause unpleasant taste, odors, and skin irritation
  • Heavy metals such as lead and mercury
  • Sediment and particulates like dirt, rust, and sand
  • Organic compounds and pesticides that affect water quality
  • Hard water minerals (calcium and magnesium) that cause scale buildup in pipes and appliances

With one system, you’re protecting your family’s health, your plumbing, and your appliances—all while improving the taste and quality of your water.

Benefits of the HALO 5 Whole House Water Filter

When you choose a HALO 5, you’ll notice immediate improvements throughout your home:

  • Better-Tasting Water – Clean, fresh water for cooking, drinking, and even brewing coffee or tea.
  • No Strange Smells or Colors – Reduces chlorine odors, discoloration, and cloudy water.
  • Gentle on Skin & Hair – Softer showers and less dryness thanks to reduced chemical exposure.
  • Healthier Living – Fewer toxins and contaminants mean less strain on your digestion and immune system.
  • Plumbing Protection – Prevents scale and sediment buildup that can clog pipes, faucets, and appliances.
  • Appliance Longevity – Dishwashers, washing machines, and water heaters last longer with filtered water.
  • Low-Maintenance Operation – The HALO 5 is designed to operate efficiently for up to 10 years with little to no servicing required.

We needed to replace our large 100 gal water heater (4.5 Ba house) and called Castleeworks when some slight leakage was visible in the drain pan. Great same-day service by Salvador Vidales, who provided the price estimate, consulted with us on options, and got us an additional discount because we were replacing with the exact same brand that they usually install, so no new major piping was rquired other than the usual new connectors. Waived the delivery fee for the new unit which was in Pomona several hours away on high traffic congestion day.. Salvador was also the installer, very capable and workmanlike. Had the whole worksite set up and old unit ready for removal when the delivery/installation guys arrived on the hottest day of the year. When the new alumuinum drain pan got dented in the installation on our raised pad which didn't look good, he pro-actively had the team pull the new unit back off and installed another replacement drain pan to make sure we were happy with the results. After the delivery guys left when the unit was in place, he worked for several more hours finishing at 7 pm. Showed good workmanship, gave us good advice. We were very happy with Salvador and the company so far at this point. Obviously the proof of the pudding will be in the new unit and our service contracts and warranties, but we're off to a very good start and would highly recommend based on this experience on Day One!

I am more than satisfied with the service I received from Castleworks Home Services. From taking my phone call after hours when I discovered that my water heater was broken and leaking, and scheduling an appointment for the very next day… to keeping me updated on the estimated arrival time of my technician including a text with his full name and photo ID was truly impressive. But what was even more impressive is the actual service itself. Justin, the technician, was extremely easy to work with. He was knowledgeable, polite, explained everything, answered all of my questions, and completed all of the work in one visit. I couldn’t ask for a better experience and highly recommend this company! 5 ⭐️⭐️⭐️⭐️⭐️

We have just had 2 excellent experiences with Castleworks. Picked up the phone right away and was great with communication via phone and text to keep us informed as to when our technician would be out. And Justin the technician himself was absolutely amazing. Knowledgeable, worked clean and quick. We had such a good experience we ended up calling them back out right away for another issue with A/C that was long overdue and had another great experience with Brendan. So hard to find reputable companies that do what they say and that you can trust. Fully recommend them. Save their number!

James Skresvig went above and beyond for me. He even changed a hose for me, completely unrelated to the job he came to do, just to help me out because I didn't have the right tool. He answered all of my questions and was very good at explaining their services without overselling anything - more like explaining options.

Besides getting our water heater running, James was very knowledgeable and gave me useful information about upgrading to tankless. Would definitely use again!
