Solving Water Problems Is Our Tradition

Our business is built on our experience, value, and exceptional service.

We Know Water!

Every Family has their tradition. Ours is solving problem water!

Merle’s Water Conditioning has remained an independent non-franchised company for over 64 years. This allows us to remain unbiased to a particular brand or product. It is important to our customers and our reputation, that we continue to seek out the most innovative, efficient and economical products available for our customers in Saint Paul, Minneapolis and surrounding areas.
