What Is a Boil Water Advisory?

A boil water advisory is issued by your local health or water authority when tap water may be unsafe to drink—typically due to a natural disaster, water main break, or detection of harmful microorganisms like bacteria, parasites, or viruses.

During a boil water advisory, it's recommended to boil tap water for at least one full minute (longer at higher altitudes) before using it for:

  • Drinking
  • Brushing teeth
  • Cooking
  • Washing fruits and vegetables
  • Making infant formula or ice

Boiling helps kill bacteria, parasites, and viruses that may be present.

Do LifeStraw filters protect during a boil water advisory?

  • LifeStraw Home Pitchers and Dispensers remove bacteria, parasites, microplastics, and over 30 contaminants—but they do not remove viruses. During a boil advisory, you should continue boiling water if using these systems.
  • LifeStraw purifiers like the Mission, Family, Community, Peak Series Gravity Purifier, and Max do remove viruses, and are suitable alternatives to boiling during a boil water advisory.
