Best Water Softener Companies
in the Twin Cities
Minnesota's hard water averages 15–20+ grains per gallon. We reviewed the top local and national water treatment providers so you don't have to.
Why Twin Cities Homeowners Need a Water Softener
If you live in the Twin Cities metro — Minneapolis, St. Paul, Edina, Bloomington, Lakeville, Coon Rapids, or anywhere in the 7-county area — you're dealing with some of the hardest water in the country. High concentrations of calcium and magnesium leave scale buildup in pipes, shorten appliance life, and cause spotty dishes, stiff laundry, and dry skin.
We evaluated six water softener brands and service providers on local expertise, pricing transparency, service quality, equipment, and overall value for Twin Cities homeowners. Read on for our full rankings.

Peterson Salt & Water Treatment ⭐ BEST OVERALL
Peterson Salt & Water Treatment is the Twin Cities' most trusted local water softener company. Family-owned and operated since 1987, they've spent over 35 years mastering the specific mineral profiles found in Minnesota's glacial aquifer water. Unlike national chains, Peterson installs USA-made Fleck and Clack systems sized to your actual water hardness — not a one-size-fits-all solution. They also offer free water testing, no-fee salt delivery, and repair service on units they didn't even install.
✔ Pros
- Free in-home water testing with no obligation
- Locally owned & operated since 1987
- High-efficiency Fleck & Clack systems (USA-made)
- Salt delivered & stacked — no heavy lifting
- No delivery fee within standard service area
- Transparent, upfront pricing — no hidden fees
- Repairs units from other companies too
- Iron filtration & reverse osmosis available
- 65+ combined years of technician experience
- Highly rated on Google & Yelp
✖ Cons
- Smaller fleet than national chains
- Service area focused on Twin Cities metro
- Not available 24/7 (business hours only)
Kinetico Water Systems
Kinetico is a well-known national water treatment brand with dealer locations serving the Twin Cities. They offer non-electric, dual-tank softeners that regenerate on demand. Equipment quality is generally good, but pricing can be significantly higher than local competitors and sales tactics are sometimes pushy.
✔ Pros
- Non-electric, demand-driven systems
- Dual-tank design provides continuous soft water
- Strong brand recognition
- Wide product line including RO systems
✖ Cons
- Among the highest prices in the market
- Franchise dealer quality varies widely
- Sales process can feel high-pressure
- Proprietary parts = expensive repairs
- Less local accountability than Peterson
Culligan Water
Culligan is one of the most recognized names in water treatment nationwide. They have a local Twin Cities franchise with installation, rental, and salt delivery programs. However, Culligan is frequently criticized for long-term contracts, rental fees that add up over time, and customer service inconsistencies.
✔ Pros
- Very well-known national brand
- Rental option available (low upfront cost)
- Wide service offering including drinking water
- Established warranty programs
✖ Cons
- Rental contracts can be expensive long-term
- Mixed customer service reviews locally
- National company — less personalized service
- Higher salt delivery prices vs. local options
- Canceling service can be difficult
RainSoft Water Treatment
RainSoft offers a full line of whole-home water treatment products and has dealers in the Twin Cities area. They are known for aggressive in-home sales presentations that can last several hours. Equipment can be high quality, but prices are often among the highest in the industry.
✔ Pros
- Comprehensive whole-home systems
- Lifetime warranty on equipment (with caveats)
- Handles both softening & filtration
✖ Cons
- Very high upfront costs
- High-pressure, lengthy sales presentations
- Lifetime warranty has significant limitations
- Dealer dependent — inconsistent local support
- Better value available from local providers
Morton is primarily known for water softener salt, but they also market consumer-grade softener units available at big-box retailers. These are DIY systems without professional installation or ongoing service support — a significant drawback for Minnesota's particularly hard water.
✔ Pros
- Low upfront equipment cost
- Available at local hardware stores
- Good for rental properties or light use
✖ Cons
- No professional installation or water testing
- Not sized to MN's specific high-hardness water
- DIY setup leads to common programming errors
- Limited warranty & no local service support
- Shorter lifespan vs. professionally installed units
Whirlpool Water Softeners
Whirlpool-branded softeners are sold at big-box retailers and are among the most commonly purchased DIY units. While the brand name feels trustworthy, these units are not manufactured by Whirlpool's appliance division — they're private-label systems that often disappoint Twin Cities homeowners dealing with high mineral loads.
✔ Pros
- Recognizable brand name
- Widely available retail purchase
- Demand-initiated regeneration on some models
✖ Cons
- Private-label units, not true Whirlpool appliances
- Underperform with MN's 15–20+ GPG hardness
- No local service or water testing included
- Poor customer support for troubleshooting
- Lowest reliability rating in our review
