A disposable water purifier consists of two, initially separate, sealed units which, before use, are assembled into a complete through-flow unit. The upper unit (I) contains, starting from the inlet (10), a micro-filter (14), a mixed-bed, nuclear-grade ion-exchange resin in wetted state (16), and another micro-filter (17) upstream of the outlet (12); this unit serves to absorb salts, ionic contaminants and charged particles. The lower unit (II) contains, starting from the inlet (20), a micro-filter (24), a layer of bacterio-static activated carbon (26), and another micro-filter (27) upstream of the outlet (22); this unit serves to absorb organic, non-charged particles and dissolved gases. An indicator (not shown) attached to the outlet serves to indicate exhaustion of the purifying capacity of the unit. |
