Q: How can I be sure that Water PreserverTM works?

A: Water Preserver™ was tested for 10 years in a scientific program of laboratory sample analysis and field-testing to ensure its effectiveness for 5-year water storage. Water Preserver™ is registered and licensed by both and federal state EPA's as effective for the long-term storing of water, in addition to killing bacteria, viruses, mold and fungus. Used nationwide, from homes, school districts and corporations to water districts, public utilities and major cities, Water Preserver™ is the #1 recommended product of emergency professionals.

Q: What about products that don't have an EPA Registration Number on the label?

A: Any product claiming to kill micro organisms in drinking water must be scientifically tested and proven to be effective. Product test data must then be evaluated and approved by the Environmental Protection Agency (EPA), which then registers all products of this type. Be alert to products that have no EPA registration number on the label.

Q: What about those new "oxygen" type products for water storage?

A: Beware; some of these products make unproven claims that range from killing bacteria to curing disease! Water PreserverTM was the first and only product of its kind registered and licensed as effective for 5-year water storage. Water PreserverTM is formulated specifically for water storage, and has been scientifically tested and proven in over 12 years of actual emergency water storage use. Accept no substitutes.

Q: How does Water PreserverTM research and testing compare with other products?

A: No other product has been as extensively tested or shown to be as effective for water storage as Water Preserver™. After an exhausting evaluation, Water Preserver™ is registered and licensed by both and federal state EPA's as effective for the long-term storing of water, in addition to killing bacteria, viruses, mold and fungus.

Q: Why can't I just use common household "bleach" to store my drinking water?

A: Common household bleach is an industrial-grade product that is not tested, approved, or recommended by the manufacturer for safe consumer use in drinking water. Water Preserver™ is manufactured with high-purity ingredients using a proprietary process to produce a highly effective form of stabilized and pH-balanced Sodium hypochlorite. The product is safety-sealed and date-coded to insure purity and potency, and it’s guaranteed 100% effective.

Q: Don't some emergency manuals suggest using "bleach"?

A: Don't be confused by this! Some sources (including the American Red Cross) recommend using 'bleach' to disinfect questionable water in an emergency situation--when there are no other sources of safe water--not for long-term water storage. Avoid this dangerous situation by storing water now!

Q: What about product safety?

A: Approved for Drinking Water. Water PreserverTM is manufactured from materials approved for use in drinking water. Water PreserverTM is manufactured with a multi-step process, using high-purity ingredients and laboratory analysis to insure potency.
