Water softeners
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 & usage
- Protects appliances — fixtures and appliances last longer
- Proven — the standard fix for Sonoma County hard water
- Low maintenance — we deliver salt & service on a schedule
Regeneration uses some water and salt — right-sizing matters. On septic, or want to skip salt? A conditioner may fit better; your water test decides.
Salt-free conditioners
Best for: moderate hardness & no-salt homes
Halo H2 Zero Ultimate & 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’ll tell you honestly which side of the line your water falls on.
Whole-house filtration
Best for: taste & odor at every tap
Carbon systems (Halo 5, H2 Zero, Big Blue) clean up chlorine taste and odor house-wide.
- Every tap — chlorine taste & odor gone
- Scale control too — on the Halo 5 & Hybrid, so appliances last longer
- Pairs well — add a softener or RO for the complete setup
- Sized to your water test — with a code-compliant install
- All major brands — we service more than we sell

Why Simeone for salt-free
Honest about when salt-free fits — and when it doesn’t.

Salt-free conditioners control scale rather than removing hardness — great for septic and salt-restricted homes, but not a cure for very hard water. We test first and tell you straight.

Salt-free questions, answered straight
Is a salt-free conditioner the same as a water softener?
No — and it’s the key thing to know. A softener removes hardness minerals using salt. A salt-free conditioner doesn’t remove them; it changes how they form so they don’t stick as scale. No salt, but the minerals stay in your water. For very hard water, a true softener still works better.
Does a salt-free conditioner need power or a drain?
Depends on the unit. The Halo H2 Zero Ultimate needs no salt, no electricity, no drain, and no backwash. The Navien saltless system is electronic, so it does use power. Neither uses salt.
Will salt-free protect my water heater and pipes?
Yes — controlling scale is exactly what these systems do, which helps protect water heaters, fixtures, and appliances. What they won’t do is give you the slippery soft-water feel or remove spotting the way a salt softener does. See our water filtration overview for the full picture.
How do I know if salt-free is right for my home?
A water test. If your hardness is moderate, or you’re on septic or avoiding salt, salt-free is often a great fit. If it’s very hard, we’ll be honest and point you to a softener. The test decides — and a recommendation isn’t guaranteed without it.
