Isn’t city water good enough with a Pentair Whole House Water Filter?

Most municipal water systems use chlorine or chloramines to treat water which are chemicals designed to kill living organisms. While they do an excellent job treating your water, these added water treatment chemicals can result in dry skin and hair, and unpleasant taste and odors that many people do not like. A Pentair whole house water filter will reduce the unpleasant tastes and smells to provide clean filtered water, rich in mineral nutrients, from every faucet, shower, and toilet in your home.

What does a Pentair water filter or water softener add to my water that might negatively impact the color, taste and odor of my water?

Pentair adds no chemicals to treat your home water for contaminants that cause unwanted tastes and odors or hard water. Our water softeners do use salt to reduce hard water-causing mineral ions, like calcium and magnesium, resulting in softer skin, shinier hair, longer lasting appliances and less scale buildup caused by hard water.

Can I take my Pentair whole house filtration system with me when I move?

Yes, Pentair filtration systems are designed to be easily removed and relocated if and when you decide to change homes. Simply put the system into bypass mode then disconnect it from the bypass and take it with you. When you are ready to have the system reinstalled, and you live in a location where we offer in-home services, our team of residential water experts would be happy to help with that process. Or, you can also call Pentair directly to see if we offer installation services near you 866-777-3469.

Pentair delivers smart, sustainable residential water treatment solutions that empower you and your family to make the most of life's essential resources. Better water doesn’t just come from your tap – our whole home filter systems and softeners reduce contaminants and related effects for refreshing, cleaner water. End-to-end.

Water Softeners from Pentair reduce hard water minerals by swapping out calcium and magnesium ions for sodium or potassium. Water Softener Alternatives, approved for use in all areas with Water Softener laws, prevent hard water scaling and etching without salt replacement bags or electricity. Both solutions address the hard water spots and mineral buildup that can give your appliances and plumbing a hard time.

We pour every ounce of our passion, energy, and ingenuity into creating industry-leading water treatment solutions, services, and technologies that help people, and our planet, thrive. When you insist on Pentair, you can start to look at your glass as “full-full.” Treating hard water shouldn’t be hard – that’s why we connect families with softening and conditioning systems tailored to their needs.
