This is the only type of bleach we recommend using for drinking water purification as it is certified by the manufacturer as being safe for this purpose.
Most bleaches available at the supermarket ARE NOT SAFE for purifying drinking water. We contacted a major supplier and asked them if their bleach was safe to use, they said it was not. DO NOT USE a bleach that does not specifically state on the label that it is safe for drinking water purification. This is because the manufacturers place additives in the bleach to help with cleaning, they do not have to declare what these additives are because they are not designed for human consumption.
The bleach we supply is safe for this purpose and the bottle also has instructions on it telling you how much to use.
This is a “must have” for all of your emergency preparations.
