5 different models of water filters were tested on the field with households of internally displaced people (IDPs). All of them can guarantee water treatment at the household level – that is at the point-of-use – and the minimization of the risk of recontamination: treated water is either safely stored in a sealed tank or ready for immediate consumption. The filters tested are produced by world-famous brands, and meet the highest standards of water purification. Some were already available on the field – due to the presence of local dealers -, while the others were imported. All the suppliers provided a certain warranty, material for initial capacity building and post-sale support, at least remotely. Households gave their opinion on the effectiveness, practicality and convenience of the filters from their own point of view, thus considering specific local conditions and different patterns of use. Some beneficiaries did not understand well the use of the filter and others complained about the need of pumping to filter water
