Full transparency on what could change that number: it rarely does
The honest exceptions are well water that needs pre-treatment for iron or sulfur before the HALO system, and homes with heavy sediment that call for a sediment pre-filter ahead of the tank. If either applies to your home, you’ll see it itemized on the written quote before you approve anything — never on the final bill as a surprise.
There’s no dispatch fee to come out, and we quote the full installed price before any work begins
The number you approve is the number you pay. Financing is available if you’d rather break the investment into monthly payments. Call (843) 256-6454 to lock in the coupon price.
The HALO H2 Zero Ultimate carries a 10-year manufacturer warranty on the system
Its inline HALO ION scale inhibitor is warrantied for 25 years. Because the system uses no electricity, no drain line, and no salt, there’s nothing to refill and no monthly operating cost after installation.
Run the math over the system’s life and the value gets clearer
A salt softener keeps charging you after install day — salt bags, backwash water, electricity. The HALO H2 Zero Ultimate’s $5,265 installed price works out to roughly $44 a month across a decade of typical use, with nothing added on top.
What the HALO H2 Zero Ultimate whole-home system includes
The HALO H2 Zero Ultimate treats every drop of water entering your home from a single tank
Kitchen, bathrooms, laundry, ice maker, all of it. Multi-stage carbon filtration strips out chlorine, chloramines, and the chemical taste and odor that come with treated municipal water, while polishing the water clear.
The built-in HALO ION conditioner then treats hard water without salt or chemicals
It uses reversing-polarity magnetic fields to keep dissolved calcium and magnesium suspended in the water instead of caking onto your pipes, water heater, and fixtures as limescale.
Unlike traditional softeners, the H2 Zero Ultimate needs no electricity, no backwashing, no drain connection, and no bags of salt
Once our team installs it, the media is designed to last about a decade of typical family use before it needs replacement — a genuine set-it-and-forget-it system, which matters if your Seabrook place sits empty part of the year. For the full system breakdown, warranty details, and how it compares to the HALO 5, see our HALO H2 Zero Ultimate page.
Where Johns Island and Seabrook Island water comes from — and what’s in it
Most homes get municipal water through St. John’s Water Company
Which purchases treated water from Charleston Water System. That water starts in the Edisto River and the Bushy Park Reservoir, gets treated at the Hanahan plant, then travels miles of pipe to reach the islands.
utility disinfects with chloramine
To keep it safe over that distance, the utility disinfects with chloramine — a chlorine-ammonia blend chosen because it stays active in the pipes longer than chlorine alone. It works, and the water meets every EPA standard. It’s also why your tap can smell like a swimming pool and leave skin dry and hair brittle after showers.
Disinfection has a documented trade-off
Byproducts like trihalomethanes form when chlorine compounds react with natural organic matter. Charleston’s levels test well under federal limits, so this isn’t a scare story — but activated carbon filtration is exactly the technology that reduces chloramine, its taste, and those byproducts before they reach your taps.
homes still run on private wells
Out toward River Road and the rural stretches of Johns Island, plenty of homes still run on private wells. Well water here often carries iron staining, sediment, and that rotten-egg sulfur odor. HALO systems can work on well water, but a water analysis comes first — we test before we quote so the system we install actually fixes your water.
salt air shortens life of outdoor equipment
On Seabrook Island, salt air already shortens the life of outdoor equipment; hard water scale shouldn’t be shortening the life of everything inside too. Filtration protects water heaters, dishwashers, and fixtures — a real consideration for rental and second homes where small problems go unnoticed for weeks.
Whole-home filtration vs. water softener vs. under-sink RO
A traditional salt softener does one job: it swaps hardness minerals for sodium so scale doesn’t form. It does nothing about chlorine, chloramine, taste, or odor — and it costs you salt, backwash water, and electricity for as long as you own it.
An under-sink reverse osmosis unit does the opposite: extremely pure drinking water, but only at one faucet. Your showers, laundry, water heater, and every other tap in the house still run untreated water, so the dry-skin and scale problems don’t change.
The HALO H2 Zero Ultimate covers both fronts at every tap — carbon filtration for chlorine, chloramine, taste, and odor, plus salt-free conditioning that keeps scale from forming. For homes that also want bottled-water polish at the kitchen sink, an RO unit can be added under the counter.

Kyle was very professional and personable in answering our questions and explaining the entire process for the installation of a gas tankless water heater. The installation was seamless, the crew (Randy & John) were great. The company’s follow-up was thorough. We are extremely impressed by the entire Blanton team.

Walker is a fantastic professional, and knowledgeable Tech! Blanton & Sons and myself are very fortunate to have his expertise. He performed my HVAC inspection thoroughly & explained all the elements to that process. I appreciated his help very much! Thank you, Walker!

We’ve had Blanton’s people out for air-conditioning, heating and several plumbing problems (it’s an old house!) they are unfailingly polite, hard-working, neat, we never have to clean up after them when they leave – I just can’t say enough good about them! Jeffrey Hoppe did a great job today – coming out on a holiday weekend without complaint!

Shawn and the entire Blanton’s team were great from beginning to end. Prompt, efficient and friendly, I highly recommend.

I called Blanton and Sons for an estimate. Brian Hardee came out and did a thorough investigation of my AC unit and had everything ready to discuss with me when he was finished. He also had quotes written down for me to visual see. He did a great job explaining to me (I have no HVAC knowledge) what was wrong with my unit and what it needed to be fixed. I highly recommend them!!

Signs your home needs water filtration now
If your water smells like chlorine
Your skin feels tight after showers, or your hair has turned dry and brittle, your water is telling on itself. Those are the classic symptoms of chloramine-treated municipal water reaching your taps unfiltered.
White crust or Cloudy glassware
Look at your fixtures too. White crust on faucets and showerheads, cloudy glassware out of the dishwasher, and soap that won’t quite lather all point to hard water minerals — the same minerals quietly scaling up the inside of your water heater and cutting years off its life.
orange-brown staining
Well-water households should watch for orange-brown staining in tubs and toilets, gritty sediment in aerators, or any sulfur smell. None of those improve on their own. One call to (843) 256-6454 gets a straight answer on whether filtration solves it.
Protect Your Pure Water
Keep your filtration system running flawlessly. Jimmy’s Comfort & Care Plan members get priority scheduling for filter changes and tune-ups, plus exclusive discounts on parts. Pure water, on your schedule.
How our water filtration installation process works
- Start with a call to (843) 256-6454 or the Redeem Now button at the top of this page. We’ll schedule a visit, look at your plumbing layout, test your water if you’re on a well, and give you the full installed price in writing — $5,265 for the HALO H2 Zero Ultimate with the current coupon.
- On installation day, our plumbers mount the system where your main water line enters the home, plumb it in with a bypass valve, and flush the media. HALO’s carbon requires a soak period before it goes live, so we handle that prep ahead of time rather than leaving you with discolored water.
- Before we leave, we run a water test to confirm the system is pulling chlorine and walk you through the bypass valve. Most installations wrap up in a single day, and we clean up like we were never there. After that, your only job is enjoying better water.

Water filtration FAQs for Johns Island and Seabrook Island
Is Johns Island tap water safe to drink?
Yes — water from St. John’s Water Company comes from Charleston Water System and meets EPA drinking water standards. Common complaints are chlorine taste and odor, dry skin, and scale buildup, caused by chloramine disinfection and hardness minerals. Whole-home filtration addresses those quality issues — it isn’t about making unsafe water safe
Do you install water filtration systems on Seabrook Island?
Yes — Seabrook Island is part of our everyday service area, and our team regularly works behind the gate. We’re based in Ravenel, roughly 35 minutes away via Main Road and Bohicket Road.
Available 7 days a week, with no dispatch fee
Will the HALO H2 Zero Ultimate work on Johns Island well water?
Often yes, but a water analysis comes first — HALO systems are built for municipal water. Iron or manganese above the manufacturer’s limits calls for pre-treatment ahead of the system. We test your well water before quoting so you get the right setup the first time
Is the HALO H2 Zero Ultimate a water softener?
No — instead of swapping minerals for sodium, the HALO ION conditioner keeps hardness minerals suspended so scale doesn’t form. You get scale protection with no salt bags, no drain line, and no electricity. Unlike a softener, it also filters chlorine, chloramine, taste, and odor at every tap
What maintenance does a whole-home water filtration system need?
The HALO H2 Zero Ultimate is designed to run maintenance-free — no filter cartridges to swap monthly, no salt to refill. Filtration media is designed to last about a decade of typical family use before replacement.
