Reverse Osmosis Water Filter

Do You Know What's Really In Your Southern Minnesota Tap Water?

Most families are shocked when they see their free water test results. Lead, PFAS, and hundreds of other contaminants pass through pitchers and fridge filters completely untouched.

Do These Water Frustrations Sound Familiar?

Most Southern Minnesota families deal with at least one of these water problems. Some deal with all three. See if any of this sounds familiar:

Strange Tastes & Odors

You take your first sip of morning coffee & taste chlorine water instead of the rich flavor you expected. It’s not your coffee maker—it’s your tap water with that unmistakable metallic aftertaste.

"Hidden" Contaminants

Our water supplies regularly contain detectable levels of lead, arsenic, PFAS “forever chemicals,” and other contaminants. That water pitcher in your fridge? Is not certified to reduce lead, PFAS, or most of what’s actually flowing in your family’s water.

Hauling Heavy Water Jugs

Every week, you load heavy water jugs into your cart at the local store, carry them inside, and stack them in the kitchen. You’re spending more annually hauling water, plus throwing away plastic bottles.

Here's What's Actually Happening In Your Water

1. Municipal Treatment Stops At “Safe Enough”
Cities treat water to meet EPA minimums, not to make it pure. Chlorine kills bacteria (and makes your water taste like a pool), but hundreds of other contaminants remain at “acceptable limits.”

2. Aging Pipes Add Contamination
Even clean water picks up lead, rust, and copper traveling through infrastructure installed 50+ years ago.

3. Standard Filters Only Remove Taste
That pitcher or a fridge filter? It’s not certified to remove the common water contaminants found in Southern Minnesota

But here’s the good news…

Thousands of Southern Minnesota families have already solved this with Culligan’s Reverse Osmosis System.

They are always very responsive to my needs and give great customer service plus their products are second to none.
Very fast friendly service! The lady on the phone that help me do my order was so kind and very knowledgeable about services that I wanted. The delivery guy was so helpful and set up everything for me. Very happy with their service!
Great to work with n water tastes great.
We had a new water treatment and softener system installed and we couldn't be more happy with it! Read the reviews for Garlick's and wasn't impressed with the customer service we would get. Had Leaf come out for a quote, and the fine print scared us off (we were not informed of this) plus we got more from the Culligan system at the same price as we would of the Leaf system.Mike, of Culligan in Fairmont, was very informative, professional, experienced, and went above and beyond in customer service. I definitely would recommend Mike, and his team in Fairmont, for your water quality needs.
Easy company to work with, friendly customer service. Fast and efficient.
I have been a customer of Culligan of Madelia for over 20 years. They are always so helpful and so quick to get out and service our equipment if needed. I can't ever say thank you enough. Wonderful people and service techs and so friendly. THANK YOU!!
The ladies who answer the phone calls are courteous, polite, respectful and knowlegeable of their jobs. The delivery guys are good, too.
Very helpful and friendly!! They do an excellent job, whether you go in or have service at your house or place of business. They have many options and walk you through whats best for your situation. I highly recommend.
The Culligan folks have done a great job taking care of our water softener needs, both softener service and salt delivery.
Great people, delivery is convenient and on time, service -- when I need it -- it fast, well done, and reasonably priced.
I dealt with Mike, and Carmen and they were absolutely amazing in addressing my water issues and my water needs. The prices were incredibly reasonable in comparison to other places. I would ABSOLUTELY recommend Culligan's in fairmont mn!!
Friendly, helpful! Fantastic people on phone and in home help!!! We needed salt this week. Due to health issues, we could not do this ourselves. It was delivered and put in the softener. We are very thankful for these people and the services they provide.
I called late in the afternoon to say that my softener was not working properly. I had a technician out first thing in the morning and within less than 5 minutes he knew what was wrong and updated the program! The softener has been working perfectly since. Thank you!! Highly recommend Culligan for your needs.
We've had nothing but good experiences with Culligan of Madelia. The office staff is friendly as are the delivery people. Very happy with their services!
Our old brand X water softener quit working after just a few years. I contacted Mike, who showed me a softener that was available in a size that fit our needs. After discussing pricing, I decided on a unit and asked when he could install it. He said that he could install it yet that day. From this point forward I am a loyal Culligan customer for life. It was a pleasure doing business with Mike and the ladies in the office
Such nice people! Great service! We have been happy customers for 2+ years!
Timely with deliveries, friendly staff, 40+ years doing business with Culligan, keep doing what has always been done!
Excellent service and products. Took care of the high arsenic and nitrate problems with our well.
Very prompt service and excellent customer service!
I take care of my brother from another state. I have called them and they have helped my brother out with water and salt. They are very friendly and helpfull
A great staff and excellent service. Have had both the water softener and RO drinking water system for many years now. We purchased the water softener and it has been great. Uses very little salt! The RO system I prefer to rent as they handle all the filter replacements, annual cleaning etc. I added the extra alkaline and mineral cartridges so it's good for drinking. We have great water thanks to Culligan. Did I mention we love the staff!!!!
Talk with Dave one of the owners I’ve known for years. Told him our issues as we live in the country with a well and hard water. Told him the system we have from Garlicks that has not worked since we have had it and was very expensive. Gary their employee came out and gave us his opinion on what was needed and within a week was out yesterday afternoon and put in a new iron filter OX5 single unit. We had a twin tank previous and had nothing but issues from day one. Low water pressure stinky water and iron residue that never could get fixed correctly. This system was almost double the price of Cilligan 18 years later. We tested it out last night with 2 showers going 2 toilets flushed wash machine filling all at the same time. NEVER would imagine being able to do that ever. We could only take 1 shower PERIOD !!Give them a call they will treat you with the best equipment and with an awesome sales guys and Gary the go to guy !!Thank you very much !! Our family of 6 is happy with a working water system for once !!
Great customer service and they always follow through on their promises!

Love the worry free service. They deliver, they service, and they follow-up. Friendly, professional and knowledgeable. They keep our service on schedule. We live in a very rural, small town area. They provide dependable service.
Becky in the Jackson office always treats you like a friend. Heather answering the service call, was a professional and helped set up the paperless billing. Culligan is very lucky to have two exceptional people. Becky and Heather, working for them and keeping the customers happy.
It has been a joy to work with Culligan! They are so good with customer service.
Great service!
I’ve had over 40 years of outstanding service with Culligan of Madelia
Love the place this ppl are awesome, great help and costumer service, its an awesome experience with soft water and R/O water.
Everything from reasonably priced services to friendly and helpful personnel can be found here. I've had nothing but positive interaction from office staff to delivery drivers.
We love the water and the convenience in price and 24 hour drive up fill up station! I let others in the area know about it
The delivery and filling my salt tank is the best. Keeping a schedule of when they need to stop by keeps me from having to worry about not having soft water. Any time there is a need for repair the technician is readily available and is normally able to come the next day after you call if not the same day.
A great water to save on drinking water
Great product, great customer service
Very professional and dependable!
Whenever I call for more salt, Becky is very helpful and pleasant! I usually have softener salt within a day or two. The person delivering is always friendly and efficient!!
Have been going to culligan for a couple of years, everything is great, friendly people all the way around.
They give great service and are very dependable.
Great employees, always have a good attitude and willing to help!
The staff are very helpful and pleasant. The water is good, and it is nice to have it automatically delivered so that I do not have to think about it.
Easy to work with and convenient. They dropped off our order at our designated site and follow up with a phone call and email confirmation. Excellent service, would use again.
I like that the water is delivered to my home. Also, very easy to work with.
I dont have to worry about never having soft water because I ran out of salt AND I dont have to carry heavy salt bags down to the softener in the basement. Hassle and worry free. LOVE IT
Very good place, great customer service.
Great service
They are very quiet and hardly noticed them.on time and polite and pet friendly.
Friendly staff
Very quick with service
I had to switch from Marshall to a local water softener supplier and Denny was a gentleman through the entire process! If I lived closer to Marshall I would have stayed with them, without a doubt!
Jim and the crew are knowledgeable, kind, easy to reach and quick to answer service calls. Thank you!
the best
Dont have to walk thru a grocery store with my jugs. Just drive up & its 14 cents cheaper a gallon than where I get it in Lake Crystal. The only down side is if you just want to fill an off size bottle there's waste because it's in gallon increments only.
Great service!
It was easy to get my water filled up a d not to costly
Great products. Nice people. Prices are fair. They are there to serve customers well.
Good people
Denny and his Crew are Awesome to work with. Every time there was a question or problem, they were always so quick to respond, answer, & resolve the issue. I highly recommend their products and services!
