What's your water doing?

Pick the closest match. Each one points to the system that usually fixes it, and a water test confirms it.

  • Chlorine taste or smell

    Common on city water in Santa Rosa and beyond. Whole-house carbon filtration removes it at every tap.

    See Halo whole-house systems
  • Spots, scale and crusty fixtures

    Classic hard water. The same scale quietly shortens the life of your water heater. A softener stops it at the source.

    See water softeners
  • Hard water, but on septic or no salt

    A salt-free conditioner controls scale with no salt to haul and no brine sent to your septic.

    See salt-free conditioners
  • You want better drinking water

    An under-sink reverse osmosis system gives you bottled-quality water from its own faucet.

On a well? Iron, rust and grit are common on west county well water, and we build treatment in stages to your water test. Not sure what you have? Book filtration service.

Tested, not guessed

Sonoma County water is hard, and every house is different

Most of the county runs on moderately hard water, typically 5.5 to 12 grains per gallon depending on the source, and Santa Rosa averages around 5.5 to 6. Wells add iron, sediment and sometimes bacteria. That's why we test before we recommend anything.

  • A free water test with any water filtration service or repair
  • The system your water needs, not the biggest one on the shelf
  • Scale control that protects water heaters, fixtures and appliances

The details, if you're comparing

Softener or salt-free conditioner: the honest breakdown

The most common question we get. Same facts, side by side. Find the column that sounds like your house, and read our guide to hard water and your plumbing for the background.

Water softener

Best for very hard water.

Ion exchange removes hardness minerals entirely. The most thorough fix.

  • Removes hardness: no more spotting, scale or dry skin
  • Sized to you: 1, 1.5 or 2 cu ft for your hardness and usage
  • Protects appliances: fixtures and appliances last longer
  • Low maintenance: we deliver salt and service on a schedule

Regeneration uses some water and salt, so right-sizing matters. On septic, or want to skip salt? A conditioner may fit better. Your water test decides.

Salt-free conditioner

Best for moderate hardness and no-salt homes.

Halo H2 Zero Ultimate and Navien saltless change how scale forms instead of removing minerals.

  • No salt: nothing to haul, nothing to refill
  • Septic-friendly: zero salt discharge
  • Low waste: no backwash water down the drain
  • Keeps minerals: conditions without softening

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

Want taste and odor fixed too? Whole-house carbon systems (Halo 5, H2 Zero, Big Blue) clean up chlorine taste and odor at every tap, and the Halo 5 and Halo Hybrid add scale control. Pair any of them with reverse osmosis for the complete setup.

Water filtration questions, answered straight

Do I need a water softener or a salt-free conditioner?

It depends on your water and your setup. A softener removes hardness minerals and is best for very hard water. A salt-free conditioner controls scale without salt, which suits septic systems and moderate hardness. We test first, then recommend.

What does a whole-house system do that a filter pitcher can't?

It treats every tap, shower and appliance, reducing chlorine, sediment and the scale that wears out water heaters and fixtures.

How hard is the water in Sonoma County?

Most of the county runs on moderately hard water, typically 5.5 to 12 grains per gallon depending on the source. Santa Rosa averages around 5.5 to 6. Our hard water guide explains what that does to your plumbing.

I'm on a well. Can you help?

Yes. Well water often needs sediment, iron and UV treatment in stages, and we match the system to your water test.

How much does water filtration cost?

Our flat rates are published: Halo 5 whole-house $4,981, H2 Zero from $2,626, Halo Hybrid 2-in-1 $5,365, salt softeners from $3,167 and 4-stage RO from $1,205. Long runs, difficult access or code corrections are priced upfront and approved by you first.

Is the water test free?

Yes, with any water filtration service or repair, including softeners and reverse osmosis: we test your water on-site at no charge.

Will I know the price before you start?

Yes. You get a fixed price approved before any work begins, so there are no surprises when the job's done.

Do you service systems you didn't install?

Yes. We repair and maintain filtration systems, softeners and RO units we didn't install, including filter and membrane changes, softener salt and settings, and UV lamps.
