• In SGS laboratory testing, the tested OASSAY sample achieved >99.999% removal of MS2 bacteriophage, a surrogate used in virus testing. This result applies to MS2 bacteriophage under the conditions of that test and does not establish equivalent removal of all viruses in all water conditions. See our Safety and Performance Data page for the reported results.
