Tired of rotten-egg odors in your water? Culligan Water Mid South offers the Aquasential® Smart High Efficiency Sulfur-Cleer® Water Filter, a whole-home solution built for well water with hydrogen sulfide and iron problems, right here in North Little Rock. 
With stars across 15 reviews and local service since 1971, we’re the team North Little Rock residents trust to install and maintain it.
What Is the Aquasential® Smart HE Sulfur-Cleer® Water Filter?
The Aquasential® Smart HE Sulfur-Cleer® is a whole-home water filter engineered to eliminate the sulfur smell and iron staining that common well water brings. It uses aeration combined with carbon filtration to oxidize hydrogen sulfide and iron into filterable particles, then removes them through activated carbon media, so every tap in your home runs clean and odor-free.
It’s monitored via the Culligan Connect® app, so you’re always connected to your system’s performance without having to check anything manually.
Who Needs This System?
This filter is built for homeowners in North Little Rock on private well water who experience one or more of the following:
- A "rotten egg" sulfur smell from hot or cold water
- Orange or brown iron staining on fixtures, sinks, or laundry
- Metallic taste in drinking water
- Iron buildup reducing the lifespan of appliances and plumbing
If your water smells or stains, this system addresses the root cause at the whole-home level.
How It Works
The Sulfur-Cleer® system uses a two-stage process:
- Aeration: Oxygen is introduced to oxidize dissolved hydrogen sulfide and iron into solid particles.
- Carbon Filtration: The oxidized particles are captured and removed through activated carbon media, neutralizing odors and clearing iron from your water supply.
The result is water that enters every faucet, shower, and appliance in your home already filtered, no point-of-use additions needed.

Frequently Asked Questions
What causes the sulfur smell in well water?
Hydrogen sulfide gas naturally occurs in groundwater, especially in areas with certain soil and rock compositions. It produces the "rotten egg" odor many well water users recognize. The Sulfur-Cleer® system is specifically engineered to remove it.
Does this system also remove iron?
Yes. The system is NSF/ANSI 42 certified for both hydrogen sulfide reduction and iron reduction, up to 10 ppm iron and up to 1,000 gallons iron reduction capacity.
Is this a whole-home filter or just for drinking water?
Whole-home. The system connects to your main water line, so every tap, shower, appliance, and fixture receives filtered water.
How is this different from a water softener?
A water softener addresses hardness (calcium and magnesium). The Sulfur-Cleer® targets hydrogen sulfide and iron, which cause odors and staining. Many North Little Rock well water homes benefit from both. Culligan Water Mid South can test your water and recommend the right combination.
What’s the Culligan Connect® app?
It’s Culligan Water Mid South‘s smart monitoring app that connects to your system via Wi-Fi. You can check water usage, system status, and receive alerts, including automatic notifications to your local Culligan Water Mid South service team when maintenance is needed.
Does the system require electricity?
Yes. It requires access to an electrical outlet (24VDC, 1W / 60 Hz) in addition to main water piping and a drain.
Where does the system install?
It can be installed in a laundry room, basement, garage, or anywhere with access to your main water line, a drain, and an electrical outlet. Your Culligan Water Mid South technician will assess the best location during installation.
How do I know when the filter needs service?
The Soft-Minder® Meter monitors your system’s performance and usage. Through the Culligan Connect® app, your local Culligan Water Mid South service team receives automatic alerts, so maintenance is often scheduled before you notice any issue.
Is Culligan Water Mid South locally owned?
Yes. Culligan Water Mid South is an independently owned and operated franchise serving North Little Rock since 1971. Local office, local technicians, local knowledge of your water conditions.
