Waterguard 150Ml

A 150 mL bottle of WaterGuard is enough to treat one month of drinking water for the average family (or 1000 liters of water) Instructions for use are simple. The process requires very little active time and relatively little wait time: add one capful of solution to 20 liters of non-turbid water (or two caps if turbid), agitate, and wait 30 min before consuming. If used within 48 h, sufficient chlorine residual remains to protect against recontamination of stored water.
