Countryside Culligan Water has been providing cleaner, safer drinking water to Winona families since 1936. With 300 reviews and 4.9 stars, our customers trust us to deliver water solutions that work, and nothing works harder than the Aquasential® Smart Reverse Osmosis Drinking Water Filtration System. 
Certified to reduce 18 times more contaminants than the leading standard pitcher filter, this isn’t just an upgrade.
It’s a different category of water treatment entirely.
What Is Reverse Osmosis?
Reverse osmosis forces water through
a semi-permeable membrane, removing contaminants at the molecular level.
The Aquasential® Smart RO goes further, with up to 14 filter options across seven filtration stages, it’s customizable to your Winona water chemistry and certified to reduce over 90 contaminants.
That’s contaminants a normal water pitcher or fridge filter can’t touch.

- PFAS (PFOA, PFOS, and emerging PFAS compounds)
- Lead
- Arsenic
- Fluoride
- Bacteria and viruses

- Microplastics

- And 80+ additional contaminants

We test. We configure. We install. And we’re here in Winona when you need us, not a 1-800 number.

That’s the difference between buying a product and having a solution.

Frequently Asked Questions
Is Countryside Culligan Water locally owned?
Yes. Countryside Culligan Water is an independently owned and operated franchise serving Winona since 1936. Local office, local technicians, local water knowledge, not a national call center.
What contaminants does the Aquasential® Smart RO remove?
The system is third-party certified to reduce over 90 contaminants including PFAS, lead, arsenic, fluoride, bacteria, viruses, chlorine, pesticides, mercury, and microplastics. It meets NSF/ANSI Standards 42, 53, 58, 401, and 372, plus NSF Protocol P231 for bacteria and viruses.
How is this different from a pitcher filter?
The Aquasential® Smart RO is certified to reduce 18 times more contaminants than the leading standard pitcher filter. It operates at the molecular level using a semi-permeable membrane, pitcher filters cannot match that level of reduction for contaminants like PFAS, arsenic, or lead.
How is this different from a box-store RO system?
Certification scope and local service. The Aquasential® Smart RO covers 90+ contaminants across six NSF/ANSI standards. Box-store units typically certify for far fewer. More importantly, Countryside Culligan Water handles installation, calibration, and every filter change; your system is maintained by a technician who knows Winona water, not by you ordering cartridges online.
Does it work with well water?
Yes. The system can be configured for well water conditions including bacteria, iron, and agricultural contaminants common in private wells. Our team tests your water before installation and sets up the system accordingly.
What is PFAS and should I be concerned in Winona?
PFAS (per- and polyfluoroalkyl substances) are a class of man-made chemicals linked to health concerns. They are found in many municipal water supplies across the country. The Aquasential® Smart RO is certified under NSF/ANSI 58 for PFAS reduction, including PFOA and PFOS, the most studied and regulated compounds.
How much water does it produce per day?
75 gallons per day, more than enough for a family’s drinking, cooking, and beverage needs. The 3-gallon storage tank ensures filtered water is ready on demand.
What’s the Culligan Connect® app?
A free app that connects to your system and gives you real-time water quality data, filter life tracking, hydration reminders, and savings calculations. Your local Countryside Culligan Water team also receives performance alerts, so service is proactive, not reactive.
How often do filters need to be changed?
Filter life varies by water quality and usage. The system monitors filter performance in real time and sends alerts through the Culligan Connect® app when a change is needed. Countryside Culligan Water handles all filter changes for you.
What does installation include?
Professional installation (under sink or remote), system configuration for Winona water chemistry, smart faucet setup, and Culligan Connect® app activation. Ongoing filter service and remote monitoring are available through your local Countryside Culligan Water team.
