What's your water telling you?

Pick the closest match. Each one points to the Halo system that usually fixes it.

  • Chlorine taste or smell

    That municipal taste and odor is disinfectant. Whole-house carbon filtration removes it at every tap.

    See Halo 5 and H2 Zero
  • Spots and crusty fixtures

    Hard-water scale builds on everything you wash and every fixture. A softener or the Halo Hybrid stops it.

    See the Halo Hybrid
  • Dry skin, dull laundry, no lather

    Classic hard water. We test your hardness on-site and size the fix to it, not one-size-fits-all.

  • You want better drinking water

    Reverse osmosis or a Halo Hydro Point drinking-water filter gives you bottled-quality water from its own tap.

  • Backed by our Make‑It‑Right Guarantee: tell us within 30 days and we come back at no charge

The details, if you're comparing

Conditioning or true softening: the honest breakdown

Same facts, side by side. Find the column that sounds like your house. Your water test settles it.

Salt-free conditioning

Best for moderate hardness and no-salt homes.

The Halo 5 and H2 Zero Ultimate change how scale forms instead of removing minerals.

  • No salt: nothing to haul, nothing to refill
  • Septic-friendly: zero salt discharge
  • Keeps minerals: conditions without softening
  • Filtration too: chlorine taste and odor handled in the same system

On very hard water a true softener still wins. We tell you honestly which side of the line your water falls on.

True softening

Best for very hard water.

Ion exchange removes hardness minerals entirely, the most thorough fix. The Halo Hybrid pairs it with whole-home carbon filtration in one unit.

  • Removes hardness: no more spotting, scale or dry skin
  • Protects appliances: fixtures and appliances last longer
  • One footprint: one system to maintain
  • Low maintenance: we deliver salt and service on a schedule

Regeneration uses some water and salt, so right-sizing matters. See water softeners for stand-alone sizes.

Halo questions, answered straight

Is Halo better than a traditional water softener?

Different jobs. Halo's conditioners control scale without salt; a softener removes hardness minerals entirely. Very hard water sometimes still calls for a softener, or the Halo Hybrid, which does both. Your water test decides.

How much does a Halo system cost installed?

Our current flat rates for a typical single-family home: Halo H2 Zero carbon filter $2,626, H2 Zero Ultimate $3,651, Halo 5 $4,981 and Halo Hybrid $5,365. Long runs, difficult access or code corrections are priced upfront and approved by you before any work begins.

Does the Halo 5 need electricity or a drain?

Yes. The Halo 5 has an automatic backwash control head that plugs into a standard outlet and runs to a drain line, cycling about once a week to keep the media fresh, using roughly 30% less water than many systems. What it doesn't need is salt. The H2 Zero Ultimate and H2 Zero carbon filter need no electricity and no backwash.

How long does Halo media last?

Halo warranties the Halo 5 tank, control head and media for 10 years, including one carbon-media replacement in that window. Real-world media life runs around 10 years (roughly a million gallons for a typical family). Harder water or heavy use shortens it, which is why we track it on a maintenance plan.

Which Halo is right for my home?

For clean-tasting city water on a budget, the H2 Zero carbon filter is the starting point, and you can add conditioning or softening anytime. The Halo 5 is the one in the lineup that also removes chloramines. Very hard water points to the Halo Hybrid. Your water test decides.

Is the water test free?

We test your water on-site at no charge with any service call. A standalone on-site water analysis is $149. It covers hardness, iron, chlorine and operating basics for system design, and it is not a certified health or lab test.

Do you service Halo systems you didn't install?

Yes. Repairs, media, membranes and maintenance plans for existing Halo systems across Sonoma County.

Can I finance a Halo system?

Yes. Qualifying projects can be financed through Synchrony, with flexible monthly payments. Ask about it when you request an estimate.
