Filter what matters in your drinking water

Not all filtration is created equal. Culligan filtration is certified for the most common—and most concerning—drinking water contaminants.
PFAS
Linked to long-term health concerns and increasingly detected in U.S. water supplies. Over 143 million Americans are estimated to have PFAS in their drinking water.(1)
Lead
A toxic heavy metal that can leach into water through aging pipes and household plumbing. An estimated 9 million U.S. homes still receive water through lead service lines.(2)
Pharmaceuticals
Compounds from prescription and over-the-counter drugs that can persist in water sources. Testing at 25 U.S. water treatment plants detected 118 distinct pharmaceutical compounds in treated drinking water.(4)
Pesticides
Chemicals used in agriculture that can migrate into groundwater and surface water sources. Pesticides were detected in 41% of U.S. public drinking water supply wells tested.(5)
Chlorine & Chloramines
Commonly used disinfectants that can impact taste, odor, and overall water enjoyment. About 98% of U.S. water treatment systems use chlorine-based disinfection to help provide safe drinking water.(6)
