Since the establishment of the International Scheme to Evaluate Household Water Treatment Technologies (the Scheme) in 2014, WHO has been independently evaluating the performance of household water treatment (HWT) technologies in removing microbial contaminants from drinking-water. The results of the evaluation are intended to guide procuring United Nations (UN) agencies and Member States in HWT selection.
The report summarizes the results of 19 of 20 HWT products evaluated in Round II of the Scheme . These represent a range of treatment methods, including chemical, solar and ultraviolet (UV) disinfection, and ceramic and membrane filtration. The report highlights that among the products that do not meet WHO performance criteria, manufacturing quality is weak, and needs to be strengthened.
