What to know about food & water storage

Food and water decide how long a household can stay at home when the power is out for days or weeks. Ready.gov suggests at least one gallon of water per person per day, and the American Red Cross suggests a 3-day supply you can take with you plus a 2-week supply at home.

This section covers how much to store, how to store it so it lasts, and honest reviews of water systems sold to preppers. The calculator does the math for your family, from 3 days to 1 year.
