Direct answer: HALO does not publish prices. Its systems are sold and installed by licensed contractors, and its warranties are void if the system was bought any other way, so the price of a HALO is the contractor’s quote for equipment and installation together. What HALO’s documents do let you estimate is the running cost: the HALO 5 uses no salt and backwashes about 10 minutes a week, the CK10 uses 6 to 15 lb of salt per cubic foot of resin per regeneration, the UV lamp is replaced yearly, and HALO’s warranties do not pay for labor except under the ION’s stated allowance.
Publisher boundary: Water System Guide is an independent research publisher, not a HALO contractor or dealer. This page uses HALO’s FAQ page, the HALO 5 installation manual and warranty, the CK10 spec sheet, manual and warranty, the Hybrid and ION warranties, and the UV spec sheet, reviewed October 15, 2026. Calculations are our arithmetic and are labeled. We do not quote equipment or installation prices because HALO publishes none.
Why there is no list price
HALO builds its contractor channel into the warranty. The HALO 5 warranty is void “if a HALO 5 System was purchased from a 3rd party, liquidator or by any means other than an authorized licensed wholesale distributor,” if “the HALO product was not installed by a licensed contractor,” or if “the product was not sold to you by a licensed contractor” (HALO 5 warranty). The Hybrid warranty has the same third-party and licensed-contractor rules (Hybrid warranty).
HALO’s FAQ mentions a “variety of price points” among the reasons it gives for choosing HALO but prints no figures (HALO FAQ). The price you pay is therefore a contractor’s package price: equipment, labor, fittings, drain and electrical work, and sometimes a pressure regulator or pretreatment. Two quotes for the same model can differ a lot for that reason. For typical installed-cost ranges across brands, see our water softener cost guide.
Which HALO you are pricing changes the cost
HALO sells products that do different jobs, and their running costs are not alike:
| System | Treatment | Salt | Regular consumables per HALO’s documents |
|---|---|---|---|
| HALO 5 (H5-100 to H5-200) | Filtration and scale conditioning | None | None listed; carbon life about 1 million gallons per the FAQ |
| CK10 (H-CK10-150, 200, 250) | Ion-exchange softening | Yes | Salt; resin warranty depends on pretreatment |
| Hybrid | Carbon filtration and softening, one tank | Yes | Salt |
| ION 2.0 Plus | Magnetic scale conditioning | None | None; no power or drain |
| UV | Disinfection | None | Lamp yearly, sleeve every 3 years |
If you need hardness removed, the HALO 5 alone does not do that; our HALO 5 vs CK10 vs Hybrid comparison explains the difference. A quote that pairs a HALO 5 with a CK10 will cost more up front, but HALO’s CK10 warranty rewards that pairing (see below).
Running costs from HALO’s documents
Salt (CK10 and Hybrid)
The CK10 manual lists three salt doses per cubic foot of resin: 6 lb for about 20,000 grains, 8 lb for about 25,000 grains and 15 lb for about 30,000 grains (CK10 manual, PDF page 5). The CK10 spec sheet gives resin volumes of 1.5, 2 and 2.5 cubic feet for the three sizes (CK10 spec sheet).
Our arithmetic, salt per regeneration:
| Model | Resin | 6 lb/cu ft | 8 lb/cu ft | 15 lb/cu ft |
|---|---|---|---|---|
| H-CK10-150 | 1.5 cu ft | 9 lb | 12 lb | 22.5 lb |
| H-CK10-200 | 2 cu ft | 12 lb | 16 lb | 30 lb |
| H-CK10-250 | 2.5 cu ft | 15 lb | 20 lb | 37.5 lb |
How often it regenerates depends on hardness and water use, which the valve tracks with its meter and hardness setting. The lower dose per cubic foot gives more grains per pound of salt; the higher dose gives more capacity per regeneration. HALO’s manual does not say which dose it ships, so ask the installer what is programmed. The manual recommends “a good grade of solar or pellet salt.”
Water
HALO 5. HALO’s FAQ says the H5-100 backwashes at “approx. 3.5 gallons per minute” for a 10-minute cycle once a week. Our arithmetic: about 35 gallons a cycle, or about 1,820 gallons a year at 52 cycles. HALO’s quick-reference guide recommends longer intervals (9 or 11 days) for smaller households, which would use less.
CK10. The CK10 manual does not publish gallons per regeneration. It does say the valve can regenerate “on demand,” based on metered water use, which it lists among the system’s features as “metered regeneration to save water.”
Electricity
The HALO 5 and CK10 both run from a plug-in transformer. HALO’s installation manual says the HALO 5 needs “a standard 2-prong, 120V, grounded outlet that is not controlled by a switch” (installation manual, PDF page 3). The CK10 manual’s specifications list a current draw of 0.5 amperes at 110 volts (CK10 manual, PDF page 4). The ION uses no power. The UV runs on 110–130 V.
Media and filters
- HALO 5 carbon. HALO’s FAQ ties carbon life to about 1 million gallons, or ten years for a family of four. The HALO 5 warranty provides “one (1) replacement carbon media package at no charge (except freight and handling) for 10 years from the date of installation due to media failure. (Chlorine only).” Freight, handling and the labor to change the media are not included.
- UV. The UV spec sheet lists the lamp “1 a year” and the sleeve “every 3 years” (UV spec sheet).
- Sediment Guard. Replacement cartridges H-SGRC510 and H-SGRC520. See our HALO parts guide.
A one-time water heater flush
HALO’s FAQ says that in a home with 4 people, “the water heater will need to be flushed (of dissolved solids) 3-4 months after the installation of the HALO 5, or any other HALO solution that includes a HALO ION 2.0 Plus,” because the ION dissolves existing scale. Budget for that service call if you do not flush the heater yourself.
Warranty terms that affect what you pay later
HALO’s warranties cover parts more generously than labor:
- Labor. The HALO 5 warranty says HALO “does not warrant to perform, pay for, or finance any repairs and/or installations.” The CK10 warranty assumes “no responsibility for consequential damage, labor or expense.” The ION is the exception: for the first 10 years it covers “the magnetic bar, housing and labor ($125 LABOR / $50 part allowance) on approved warranty claims” (ION warranty).
- Freight. HALO 5 replacement parts come “at no cost, except freight, handling charges,” and no more than two parts per claim.
- CK10 pretreatment. The CK10 warranty covers valve and electronics for 5 years and resin for 1 year, but extends the valve to 10 years and the resin to 10 years “if CK10 is pretreated with a HALO 5, H2 Zero or Mini system” (CK10 warranty).
- Chlorine. HALO 5 and Hybrid warranties require influent chlorine not to exceed 1 mg/L. The CK10 warranty excludes media and internal valve parts at 1 ppm chlorine or above.
Costs a quote should spell out
Several HALO conditions add cost at installation, and they are cheaper to deal with up front than after a denied claim:
- Pressure regulation. The HALO 5 warranty requires 40 to 80 psi and says pressure above 80 psi “voids all warranties.” The Hybrid warranty sets 30 to 80 psi. Ask whether a pressure-reducing valve is included.
- Well water report. Both warranties are void if the system is installed on a well “without a current well water report being submitted for recommendation to HALO.”
- Drain and power. The HALO 5 needs a drain (3/4” threaded outlet) and an unswitched 120V outlet. The manual says to “contact an appropriate tradesman” if more plumbing, drain or electrical work is needed.
- Recirculation loops. If a recirculation pump is in use, the HALO 5 warranty calls for “a secondary HALO ion conditioner on each recirculating loop.” That is extra equipment.
- Warranty activation. The HALO 5 warranty is void if you “did not activate the warranty online.” Ask the installer to register it in your name.
- Leak protection. HALO accepts no responsibility for water damage and recommends a water pan and leak detector in high-risk areas.
Questions to ask before signing
- What exact HALO model and size are you quoting, and what water test supports it?
- Does the price include the bypass, drain, electrical, pressure regulator and any pretreatment?
- Which salt dose will the CK10 be programmed for?
- Who pays labor on a warranty claim, and what do you charge for a service call?
- Will you activate the warranty in my name?
Frequently asked questions
How much does a HALO water system cost?
HALO does not publish prices. It sells through licensed contractors, and its warranties are void for systems bought from third parties or not installed by a licensed contractor. Get written quotes that list the model, installation work and any regulator or pretreatment.
Does the HALO 5 have ongoing costs?
HALO calls it maintenance free and uses no salt. It backwashes about 35 gallons a week by our arithmetic for an H5-100, uses a small amount of power, and HALO’s FAQ calls for a one-time water heater flush 3 to 4 months after installation.
How much salt does a HALO CK10 use?
The manual lists 6, 8 or 15 lb of salt per cubic foot of resin per regeneration. By our arithmetic, that is 9 to 22.5 lb for the 1.5-cubic-foot H-CK10-150. Frequency depends on hardness and water use.
Does HALO’s warranty pay for labor?
Generally no. The HALO 5 and CK10 warranties exclude labor and charge freight and handling on parts. The ION 2.0 Plus warranty is the exception, with a $125 labor and $50 part allowance on approved claims in the first 10 years.
