Whole Home Filters & pH Neutralizers

Acid Low pH in Water

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.

Our system started leaking last night and we had to turn the water off to the house. I called the emergency line and Dalton came out immediately even though it was 830 at night. He promptly fixed it and in fact, upgraded our parts so we wouldn’t have any problems in the future. He was pleasant And friendly. He was a real lifesaver.
Andrew was fantastic—friendly, professional, and easy to work with. He was extremely knowledgeable about the products and took the time to walk us through the options, ultimately helping us select the one that best fit our team’s needs. It’s been a perfect addition to our breakroom, and we couldn’t be happier!
Lisa High was our sales person. She was very personal and friendly. No pressure to make an immediate decision, she just explained options. Our Culligan water feels great, tastes great, and we no longer have to squeegee the shower doors!
Dalton came out today to service my water system. He was very friendly, knowledgeable, and timely. He went above and beyond for me. I truly appreciate the exceptional service that was provided by him and the company. I would recommend Dalton and Culligan to anyone looking for a water filtration system.
