Citrus extract is known to have some bacteriostatic effect. This product was introduced
in the health food market and is now looking for a broader market. Company data from
independent labs support bacteriocidal and virucidal effects. However, protozoal tests
were done with trophozoites, not cysts. The data has gaps and too much of the marketing
is testimonial to give a recommendation now. The chemical species or compound
responsible for disinfection needs to be identified, then dose/time disinfection values
experimentally established for various microorganisms.
Aerobic Oxygen
Aerobic Oxygen was initially introduced into the health food market but are now being
offered to the general travel market. It is advertised not only as a water disinfectant, but
for nearly miraculous qualities from strengthening the immune system and energizing to
curing headaches and tropical fish diseases. Company literature implies that the active
disinfectant is chlorine dioxide, ozone, and free oxygen radicals, but this is not
chemically feasible. Company-sponsored testing demonstrates activity against bacteria
and viruses, but not against cysts. No dose/time response has been developed to compare
the product against other disinfectants. It cannot be recommended without further data.
