Whole-Home Filtration, Built for Winona Water
Countryside Culligan Water has been solving Winona water problems since 1936, and the Aquasential® Smart High-Efficiency Water Filter is our most advanced whole-home filtration system yet. 
Whether your water carries sediment, chlorine, or acidity, this system is customized to address the specific issues affecting your home, at every tap, every shower, every appliance.
Rated 4.9 stars across 300 reviews, Countryside Culligan Water brings professional installation and ongoing local service to every system we put in.
Why Winona Residents Choose the Aquasential® Smart HE Water Filter
Winona water isn’t one-size-fits-all. Sediment levels, chlorine taste, and water acidity vary by neighborhood, water source, and season. A box-store filter treats your water like it’s generic. The Aquasential® Smart HE doesn’t.
This system is configured at installation to address your specific water chemistry, then monitored in real time through the Culligan Connect® app. If something changes, you know about it before you taste it.
Key Technologies
Soft-Minder® Meter
Advanced diagnostics and daily water usage monitoring built into the system. Tracks filter performance and alerts you when service is needed, so you’re never guessing about your water quality.
Quadra-Hull® Tank
A four-layer tank design engineered to resist UV rays, rust, and corrosion. Available for indoor or outdoor installation, with a lifetime warranty on the tank itself.
Culligan Connect® App
Remote monitoring from your phone. Check usage, receive alerts, and stay informed about your system’s performance without ever going to the basement. The same app used across Countryside Culligan Water‘s full product line.
External Leak Sensor (Optional Add-On)
An optional sensor that detects appliance leaks and alerts you before water damage occurs, a smart addition for homes with older appliances or finished basements.
Three Filter Options, One System, Your Water
The Aquasential® Smart HE is built around three certified filter media, each targeting a different water problem. Countryside Culligan Water tests your water and recommends the right configuration for your home.
Filtr-Cleer® Filter
Targets sediment, including dirt, silt, and clay. Certified for Class IV particulate reduction (particles ≥15μm to <30μm) while maintaining water pressure throughout your home.
Cullar® Filter
Addresses chlorine taste, odor, and discoloration. Certified under NSF/ANSI Standard 42. Available in 9" (up to 120,000-gallon capacity) and 10" (up to 180,000-gallon capacity) models.
Cullneu® Filter
Neutralizes acidic water, the kind that corrodes pipes and fixtures over time. If your Winona water is eating away at your plumbing, this is the configuration for you.

Frequently Asked Questions
What does the Aquasential® Smart HE Water Filter remove?
The system addresses sediment (dirt, silt, clay), chlorine taste and odor, and water acidity depending on the filter configuration. Countryside Culligan Water tests your Winona water before installation and recommends the right filter media for your specific situation. Filtr-Cleer® handles particulate, Cullar® handles chlorine and discoloration, and Cullneu® neutralizes acidity.
Is this different from a drinking water filter?
Yes. The Aquasential® Smart HE is a whole-home system installed at your main water line. Every tap, shower, appliance, and fixture in your home receives filtered water, not just one sink. For drinking water contaminant reduction including PFAS and lead, Countryside Culligan Water also offers the Aquasential® Smart Reverse Osmosis system.
How does Soft-Minder® technology work?
Soft-Minder® is a built-in meter that tracks your water usage and system performance daily. It monitors filter capacity and alerts you when service is approaching, so you always know your system is working and never get caught with a depleted filter.
Can I monitor the system remotely?
Yes. The Culligan Connect® app lets you check your system’s status, review usage data, and receive alerts from your phone. You can also contact Countryside Culligan Water directly through the app when service is needed.
How long do the filters last?
Cullar® filters are rated for up to 120,000 gallons (9" model) or 180,000 gallons (10" model). Filter life varies by water usage and local water conditions. Soft-Minder® tracks capacity in real time and notifies you when a change is needed.
Is the system available for outdoor installation?
Yes. The Aquasential® Smart HE is available in both indoor and outdoor models, with the Quadra-Hull® tank designed to resist UV rays, rust, and corrosion in exterior environments.
What is the Quadra-Hull® tank?
A four-layer tank construction built for durability and longevity. It carries a lifetime warranty and is engineered to hold up against UV exposure, rust, and corrosion, whether installed inside or outside your home.
Does it require electricity?
Yes, the system operates at 24VDC, 21.6W, standard for whole-home water treatment equipment.
How is this different from a big-box water filter?
A store-bought filter uses generic media and doesn’t account for your local water chemistry. The Aquasential® Smart HE is configured by Countryside Culligan Water based on a water test, professionally installed with the right filter media for Winona water conditions, and backed by local service from technicians who know your system.
What’s included with installation?
Professional installation by Countryside Culligan Water, system configuration based on your water test results, setup for the Culligan Connect® app, and access to ongoing local service and filter changes. Countryside Culligan Water has been doing this in Winona since 1936.
