Water Purification Company reviews in St Paul, Minnesota

Couldn’t be more pleased with the service we received today. I am definitely going to look into doing a whole house water analysis and look forward to an estimate for additional water filtration system.
Thank you for your knowledge and expertise! Our technician was Rob A.
I asked a million questions and he answered every single one!

John at Merle’s was great to work with both at the initial consultation and at the follow up water test after my softener installation. Merle’s was very easy to work with from start to finish with great service all around. Highly recommend for water softener purchase and installation

I worked with both John Merle and Anthony Erickson to get a home RO System scoped and installed. They did a fantastic job and the their staff had excellent communication to schedule and let me know when they would arrive. 5 stars!

Zack was great. He explained everything to me when all was installed. He did not make any mess that he did not clean up very professional and a job well done. When John came and gave me a bid I could just tell that he was outstanding in his job, and a person I would like to deal with. Thank you Merle's Water Conditioning.

Merles get's our unreserved high recommendation! From our first contact with them and throughout the entire process we were informed and treated kindly, joyfully and respectfully. The office personal, the salesman and the technician were a joy to work with. Friendly, prompt, and efficient. This family owned business made us feel like we were part of the family. Nothing but positive input from us! Thanks for your great service!!

Man I got to tell you, my brother in law told me about this company. Sept of 2024 sales rep John came out and gave me a bid. I was blown away how affordable for a new water softener was going to be. John is such a a trustworthy guy I liked him from the very start. The installer was named Gary. Talk about skill and craftsmanship, this unit is going to last forever. I went today oct 14th 2025 to get some salt and met Annette. She loaded up 3 - 50 lb bags of salt in my car. Talked about 1st class service. Thanks to the whole gang. You would be smart to be a new customer. Tell them Rennie sent you.

Fantastic experience from start to finish. When purchasing our home, Merles had installed the previous Hellenbrand system that operated flawlessly from 2011-2025–that’s why they got a call from me to replace the old system.

John stopped by to test our water and confirm that it’s not working, or in our case, hardly working at all. He showed me test result and we went over machine options. Of course, I knew I wanted something very similar to what we had and they had the newer versions available from Hellenbrand.

What they sell is not your standard Menards or Home Depot unit. These are commercial grade units that are built to last. Those of you in the south metro area know just how horrible the water hardness is and their units last. Don’t waste your time with something that will break or fully degrade in 3-4 years.

Our new water softener with additional filtration was installed 4 days later and we are back up and running. Anthony did a great job removing and replacing the old system in under 2 hours. They even re-piped part of my home that wasn’t on the original softener line.

Overall, great service, great install, and pricing was close to what I was expecting. This is 100% one of those “you get what you pay for” situations.

Thank you!

Merle’s was fantastic! They were recommended by our realtor and had availability to come out to provide a quote and install a water softener almost right away. Communication was fantastic and there was no pressure to buy the most expensive product. Everyone we interacted with was super friendly!
