Alkaline mineral stage

Re-mineralizes the water, raises pH, balances taste. The reason it tastes like good drinking water rather than flat distilled.

Answers, not sales calls

Frequently asked questions.

Do I need a water softener for city water in Summerville?

If your home is on Summerville CPW, which includes most of Nexton, Cane Bay, Carnes Crossroads, Foxbank, and Summerville proper - your water is about 5.5 to 7.2 grains per gallon, which is where moderately hard starts to show visible effects on appliances, fixtures, and soap performance. Whether a conditioner or softener makes sense depends on your water heater age, appliance mix, shower feel, and bottled-water spending. We run the math with you during the free water test.

Is Puronics NSF certified?

It depends on the model. We will show you the exact certification scope for the specific Puronics product recommended for your home, in writing, before you decide. The Puronics Hydronex iGen C whole-home conditioner is WQA-tested and not currently NSF listed for contaminant reduction as of April 2026. The Puronics Pur-Alkaline point-of-use reverse osmosis is plumbed to your kitchen tap when specific contaminant concerns matter. Verify any listing at info.nsf.org.

What does a whole-home water system cost in Charleston?

Our standard whole-home Puronics install is priced transparently at $7,999 for most homes. That breaks down to as low as $95 per month with approved financing (3 to 12 year terms at 9.9% APR through partner lender, subject to credit approval; the 12-year endpoint is the most-chosen) or $2.19 per day over 10 years. The free water test is the starting point for any quote.

How long does install take?

Most whole-home Puronics installs take a few hours, typically under half a day. Newer homes in Nexton, Cane Bay, Carnes Crossroads, and Foxbank usually have the main water shutoff in the garage, which keeps the install clean and fast.

Is Puronics better than Culligan?

It depends on what you are trying to do and which equipment each dealer recommends. The differences that matter usually come down to warranty terms, the installer licensing and experience, pricing transparency, and whether the specific model has NSF certification for the claims you care about. We are an authorized Puronics dealer, we will show you the certification scope and we will not hide the price.

What financing options are available?

Three financing programs through our partner lender plus cash, all subject to approved credit. The 9.9% APR path runs any term from 3 to 12 years; the 12-year endpoint is the most-chosen at $95 per month. The 0% APR path runs 18 to 24 months at $444 per month or $333 per month respectively. Or $7,999 cash, paid once. No prepayment penalty on any financing path. We walk you through the numbers during the water test.

How much does a water softener cost in Charleston SC?

A whole-home Puronics water conditioning system from Pristine costs $7,999 installed for most Summerville and Charleston Lowcountry homes. That is as low as $95 per month with approved financing (3 to 12 year terms at 9.9% APR through partner lender; the 12-year endpoint is the most-chosen). Culligan and Kinetico quotes in the Charleston market typically run $9,800 to $14,200 installed, priced only after a 60 to 90 minute in-home sales call. HALO via Holy City HVAC, a salt-free conditioning option that does not remove the hardness minerals, lands in a $2,000 to $5,000 industry-typical range.

Is it cheaper to buy a water softener online or have one installed?

A DIY unit off a box site can be $1,000 to $3,000 for the equipment alone, but a whole-home system requires a main-line plumbing cut-in that in South Carolina falls under SC Code 40-59-20(7), residential plumbing work over $500 requires a licensed Residential Plumber. Permit, installation, sizing, and ongoing warranty coverage are the reasons most Summerville homeowners choose professional installation. Pristine publishes $7,999 installed, end-to-end.

What is the average price of a whole-home water system in Summerville SC?

Charleston-market quotes for whole-home water conditioning or softening systems in Q1 2026 range from $4,500 for Amazon-sourced DIY kits up to $14,200 for premium dealer franchises like Kinetico and Culligan. Pristine publishes $7,999 installed as our standard Puronics whole-home configuration, and most homes fall in a $6,000 to $10,000 quote range when the site requires additional plumbing work.

Is HALO the same as a Puronics whole-home system?

No, they solve different problems. HALO uses template-assisted crystallization (TAC), which leaves the hardness minerals in your water but treats them so they do not form scale on appliances. A post-install hardness test on a HALO home will read the same number as before install, the minerals are still there, just conditioned. The Puronics Hydronex iGen C is a true ion-exchange softener: calcium and magnesium are removed and replaced with sodium, so a post-install hardness test reads near zero. Choose HALO if you specifically want to keep the minerals in your water and prevent scale; choose ion-exchange if you want softer-feeling water in the shower, no scale, and lower soap consumption. Pristine is an authorized Puronics dealer because in Summerville at 5.5 to 7.2 grains per gallon, with chlorine and Lake-Moultrie-sourced water, the ion-exchange plus carbon plus reverse-osmosis combination is the configuration we stand behind.

How much does HALO water treatment cost in Charleston?

HALO does not publish prices. Industry-typical installed cost for the HALO 5 (the flagship whole-home system) in the Charleston market lands in the $2,000 to $5,000 range. The exclusive Charleston distributor is Holy City Heating and Air (238 East Bay Street, Charleston, SC). Pristine publishes $7,999 installed for the Puronics Hydronex iGen C whole-home configuration; the equipment and warranty differ substantially between the two products, so a direct dollar-for-dollar comparison without reading the mechanism and warranty rows is incomplete. See the side-by-side at prstnwtr.com/comparison.

Does HALO actually soften the water?

Not in the traditional sense. HALO is a water conditioner, not a softener. It uses template-assisted crystallization to convert dissolved calcium and magnesium into inert crystals that do not adhere to surfaces. Your shower head, dishwasher, and water heater are protected from scale buildup, but the underlying hardness number (grains per gallon) does not change because the minerals are still in the water. If your priority is preventing scale, HALO is a real option. If your priority is the softer-feel-on-skin and the soap-lather difference, ion-exchange softening (Puronics, Culligan, Kinetico) is what changes that experience.
