The AquaRain® Natural Water Filter will provide your family and loved ones with laboratory proven safe drinking water...without electricity, without plumbing, and without pressure or chemical pretreatments. Our patented sub-micron ceramic technology positively removes dangerous living organisms and harmful bacteria from your drinking water...naturally...using microfiltration and gravity. A dense and highly adsorptive carbon filter bed has been incorporated within the ceramic shell and sterile metallic silver added to maintain purity in the filter system. The attractive super-sanitary stainless steel housing is press-formed without seams or welds and has easy lift handles. A unique "splash guard" system insures safe drinking water in daily operation. Here is what may be the best part... the AquaRain® can produce quality drinking water for less than 2¢ per gallon!
