Why filtration matters

Drinking water is regulated, but not all standards are the same—and private well water isn’t treated at all. Culligan helps you navigate what that means for your water.

Widley detected substances

Over 320 toxic substances have been identified in U.S. drinking water systems, while federal standards regulate only a fraction of them.

Persistent "forever chemicals"

New EPA data estimate that about 165 million Americans may be exposed to PFAS “forever chemicals” in their drinking water.

The plumbing in between

Even treated water can be affected by old pipes. More than 9 million U.S. homes still rely on lead service lines, increasing the risk of contamination at the tap.

Added peace of mind

Filtration provides an extra layer of confidence for cleaner, more consistent drinking water at home—Culligan solutions are independently certified to reduce a broad range of contaminants.

Bottled water isn't better

Bottled water isn’t always the cleaner choice it appears to be.

Many bottled water brands rely on municipal water sources and are regulated differently than tap water, with less frequent testing and limited transparency.

  • Plastic pollution

    Bottled water creates massive amounts of plastic waste that clogs landfills and oceans.

  • Forever chemicals

    Global studies have found PFAS in over 90% of bottled water samples tested across multiple countries.

  • Microplastic risks

    Bottled water contains significantly higher levels of microplastics than tap water, posing potential health risks.

Discover what’s in your water

There aren't just contaminants in you water.

Total Dissolved Solids(TDS) is a measure of all the substances hiding in your water, good and bad. This includes everything from contaminants to minerals and other compounds.

Measuring TDS helps you determine if your water is free of anything that could affect its taste, odor, and appearance.
