Whole Home Filters & pH Neutralizers

Culligan whole home filters & pH neutralizers reduce corrosion to your pipes, damage to water-using appliances and red & blue/green stains in your sinks & tubs.

Water with a low pH is considered to be acidic. The acidity of the water can cause corrosion to plumbing, hot water heaters, washing machines and dish washers. It’s also hard on hair and skin. A telltale sign of low pH water is the blue/green stains on your fixtures.

Our unique Whole Home pH neutralizers boost the alkalinity of your water, increasing the pH naturally for the ENTIRE home. Plus, it cleans itself automatically and requires very little maintenance.

Other types of whole home filters reduce iron as well as other non-dissolved minerals in your water so you no longer will have red stains in your sinks, tubs and fixtures.

Lana Geurts

I have dealt with Culligan for years with salt delivery for the water softener. Now purchased a water cooler with bottom loading. Love it😁 2/17/25 Having issues with water cooler. Tech comes it works, but in between it quits working on and off. I wouldn’t buy a bottom loader again.

Tony Bloom

Great and dependable service. Down to earth people with no pressure sales involved. Have been servicing our equipment for years. NEVER an issue or concern with Culligan. The only thing they could do better is to bring the donuts with the salt delivery (just kidding!). Highly recommend them for your soft water needs.

Ira Hartoch

Very friendly and dependable service. If you aren't home for a delivery (and feel comfortable doing so) you can leave an entry open for them,let them know how to get in, and they deliver and fill your salt tank. They also take care of your equipment (if needed) in a timely manner.

Dwight Weber

I have been a water softening customer of Metzner's for a couple of years and recently decided to add a RO system to our home. From the initial call, the consult with Tony, the install with Chad and the follow up visits Metzner's delivered exactly what they said they would. The consult was thorough, the install was professional and not only did they do an onsight follow up to ensure no issues / leaks; they also did a phone follow up to ensure I was satisfied. I strongly recommend Metzner's Culligan to anyone looking for a water softening or RO solution. Thank you!!

Patricia M Jones

David Duquette

Cats Movie Channel

Great service. Great water. No issues. Culligan is extremely professional and kind.We have had Metzner’s Culligan drinking water for 5 years. How many plastic water bottles is that? Saved. Handled. Purchased.We liked it so much we now have their water softener, which has also been working so much better than our other one that just didn’t meet our needs. (Kaukauna)
