What could be more important than clean, safe water? 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 space-age ceramic technology positively removes dangerous living organisms and harmful bacteria from your drinking water...naturally...using micro filtration and gravity. A dense and highly absorptive 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!

How The AquaRain System Works...

The AquaRain® system filters water in a very natural way using gravity to gently draw water down through our "cultured" ceramic stone in much the same manner as nature processes ground water through the earth. The micro fine pore structure of our ceramic media will remove dangerous organisms such as protozoan cysts (Cryptosporidium, Giardia lamblia) and microscopic bacteria (E. coli, Salmonella typhimurium, etc...). Enclosed within the hard ceramic shell we have incorporated a concentrated bed of Granulated Activated Carbon (GAC) that contains a self-sterilizing metallic silver. The high performance silvered GAC bed will adsorb various organic chemicals such as MTBE and pesticides, remove chlorine compounds including carcinogenic halogens, and improve the taste and odor of the water. To the benefit of good health, our system will also leave unchanged the naturally occurring electrolytes and minerals found in your water. How Ceramics Work... Ceramic water filters work in three ways. First, surface sieving, much like a screen door, does not allow larger particles to pass through the outer surface of the filter. Second, ceramic filters operate as a depth media, providing a twisting, tortuous path like a maze, trapping contaminants within the walls (usually in the top .005" below the surface). Third, surface charge or adhesion, whereby contaminants that are small enough to penetrate the walls of the ceramic may cling to the walls like opposite polarity magnets attract each other. This surface charge is often greater than the force of the water flow that might otherwise dislodge the contaminant. This is particularly true with gravity or siphon-fed ceramic applications. Wall thickness is particularly important with regard to a ceramic’s performance as a depth media. The maze-like, tortuous path allows for filtration performance at an effective pore size that is much less than the actual median pore diameter of the diatoms from which the filter is made. As clogged filters are cleaned to restore flow, contaminants in the top .005" of surface material are removed. Gentle abrasive cleaning will gradually reduce wall thickness, making a reliable end-of-life indicator or gauge absolutely essential for easy determination of expended ceramics.

How to operate the AquaRain:

The operation of the AquaRain® Natural Water Filter is simplicity itself. No energy is required nor are chemicals necessary for the filter system to work. Water is poured into the upper container where it trickles down by gravity through the highly specialized ceramic filter elements leaving cysts, bacteria and sediment in the outer layer of the ceramic. After passing through the thick ceramic wall, the water then flows through a bed of silvered coconut shell carbon which adsorbs pesticides, various organic chemicals, and chlorine (if present), along with objectionable color, tastes and odors. The filtered water then drips into the lower container where it is stored for easy dispensing with the handy lever-action faucet. New, dry elements will need several gallons of water run through them, sometimes 10 or 12, before they are fully wetted and reach their maximum flow rate. In normal usage, water for filtration is placed in the upper vessel in the evening and allowed to filter through overnight. In the morning, most of the water should have filtered through into the lower dispensing container. Additional water may then be added to the upper container for filtration during the day. If maximum production is desired, it will be necessary to keep the upper vessel as full as possible, perhaps refilling every fifteen minutes. To halt the production of filtered water, simply lift the upper container off and empty it. If desired, the stainless steel lid can then be placed on the bottom container which may be used as a convenient and compact counter-top water dispenser. Over time, small particulates and bacteria may accumulate on the walls of the elements and slow the production of water through the filter. When this occurs, simply remove each of the filter elements and lightly clean the hard surface of the ceramic with a brush or the scrub pad provided. The elements are then reinstalled in the upper filter vessel. Proper cleaning will restore the AquaRain® Natural Water Filter to full flow rates, each and every time.
