Chemical contaminants dissolve into water and are often tasteless, odorless, and invisible.

Their impacts can be subtle at first, but long-term exposure can cause serious health problems.

Major chemical contaminants include:

• Lead: Enters water through old pipes, solder, and plumbing fixtures; highly toxic even at low levels, especially for brain development in children.
• Arsenic: Naturally occurring in groundwater; long-term exposure linked to cancer, heart disease, and skin conditions.
• PFAS (“Forever Chemicals”): Man-made chemicals used in non-stick cookware, firefighting foams, and industrial processes; persistent in the environment and linked to hormone disruption, immune suppression, and cancer.
• Chlorine and Chlorine Byproducts: Added to disinfect municipal water but can create harmful byproducts like trihalomethanes (THMs) and haloacetic acids, associated with increased cancer risk over time.

Important note:

Filtration methods must be carefully matched to the type of chemical you’re targeting — not all filters remove all chemicals.
