Sodium chlorite (NaClO2) can be converted into chlorine dioxide (ClO2) through a chemical reaction, usually an acid. The acid serves to lower the pH of the solution and initiate the conversion of sodium chlorite to chlorine dioxide. The conversion of sodium chlorite to chlorine dioxide is used for water treatment, as a disinfectant, and many other industrial uses. Chlorine dioxide's powerful oxidizing properties eliminate harmful microorganisms and contaminants. Biotab7 is not affected by pH. Just add small solid tabs to water to create chlorine dioxide (ClO2). This method means buyers can purchase "dry" product, which is much lighter to ship, does not use bulky plastic containers that end up in landfills, and requires just a fraction of the storage space. Biotab7 has a Covid kill rate of 60 seconds and is safe for all commercial and residential needs. Greater Good Tech is the exclusive USA distributor for EPA registered Biotab7, and also ships worldwide.
