Chlorine keeps water safe—but it’s not without trade-offs.

Pros of Chlorine

• Protects against waterborne illness
• Prevents contamination in pipes
• Cost-effective for communities
• Strictly regulated by the EPA

Cons of Chlorine

• Chemical taste and odor
• Can form disinfection byproducts (THMs & HAAs)
• May irritate skin and hair
• Can contribute to pipe and appliance wear

While chlorine levels are considered safe, many homeowners prefer to reduce exposure for taste, comfort, or peace of mind.
