Emergency Water Filter Hacks

In an emergency where regular water service has been interrupted – like a hurricane, flood or water pipe breakage – it is not only essential to have a water supply, but also to have ways of treating water if needed. Here are some ways to filter bad water and purify it for safer drinking.

One of the easiest and most popular ways to make sure water is safe to drink is by boiling it. This process kills bacteria and viruses; however, it does not remove any sediment, dirt, or particles.


If you can’t boil water, disinfect water using household bleach. You can disinfect a gallon of water with just 16 drops of chlorine bleach or a quarter with only four drops.

Use one gram to 5 liters of polluted water. Please note, the water is still not thoroughly purified and still requires further filtering to be safe to drink.
