Health Effects
Haloacetic acids are disinfection byproducts linked to increased cancer risk. Long-term exposure may also cause liver and kidney damage and reproductive problems.
How Haloacetic Acids (HAA5) Gets Into Water
Formed when chlorine or other disinfectants react with naturally occurring organic matter in water. Like trihalomethanes, they are an unintended consequence of water treatment.
How to Remove Haloacetic Acids (HAA5)
Activated carbon filters are effective at removing haloacetic acids. Reverse osmosis and distillation also provide good removal.
Recommended: Activated Carbon Filter
Granular activated carbon or carbon block filters effectively reduce chlorine, trihalomethanes, and haloacetic acids.
