H20 ResQ's patented water treatment is a completely mineral and organic product. Instead of chlorine treatments that dissipate quickly, this treatment will last for a minimum of 5 years. It primarily uses a copper ion that is the first solid surface material to be recognized by the EPA as antimicrobial and is permitted to make health claims.
This is the best water treatment we've found for long-term water storage. Use it and have water good for 5 years!
