How to Disinfect Water by Boiling Let water sit for an hour or two after filtering to allow any sediment to settle. Pour the clear water off the top into another container. Be careful not to dump the sediment into the new container. Boil filtered and settled water vigorously for one minute (at altitudes above a mile, boil for three minutes). Don't start the clock until you have a good rolling boil going. To improve the taste of boiled water, aerate by pouring it back and forth between containers and let it stand for a few hours.

Does Hot Water Kill Bacteria? Specific water temperatures for killing germs are difficult to pinpoint, but drinking water provides a good reference. To sanitize water for drinking, the Environmental Protection Agency (EPA) recommends boiling the water for at least 1 minute, at altitudes up to 5,000 feet. At higher elevations, water should be boiled for 3 minutes. So that's 212 degrees F (at sea level) to reliably kill bacteria and pathogens to make water potable. By contrast, most dish and clothes washing is done at temperatures lower than 120 degrees (the standard setting on home hot water heaters), so it's not safe to assume you're killing a lot of germs with the hot water.
