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 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!

High-Tech Ceramic Filter Elements

At the heart of our natural process micro-filter are patented high-tech ceramic filter elements specifically designed for the AquaRain® system. Our state-of-the-art sub-micron ceramic elements filter 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 microfine 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 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 in your filtered water.

You can depend on the proven technology used in the AquaRain® and even the natural concept that it relies upon to produce safe drinking water for your family. The AquaRain® Natural Water Filter is manufactured to meet stringent NSF standards and fully achieves the USEPA requirements of a Cyst and Bacteria Water Purifier. Best of all, the AquaRain® is made with loving care right here in the USA with American Innovation and American Technology!

Product Innovations

AquaRain Gravity Water Filters offer several unique innovations that set them far ahead of other ordinary water filter systems:

Patented Extrusion Process

A patented extrusion process produces a perfectly formed ceramic "tube" that has exacting characteristics. The wall dimensions and concentricity are tightly controlled, allowing an exact external measurement of the remaining wall thickness with a safety gauge.

Accurate kilns

The ceramic elements are fired in small computer-controlled kilns which allow complete and accurate control of the porosity of the finished product. The firing of the ceramic is the critical step in the process that determines the final performance. Our ceramic elements are by far the most consistent, high performance ceramic available. Extensive laboratory testing proves it.

Wear guage for safety

Filter elements incorporate an end-of-life caliper gauge for measuring the remaining life of each element. When this highly accurate gauge can easily slip over the ceramic, the thickness of the ceramic wall has been reduced through cleaning to the point that we recommend replacing the element. The end-of-life measurement is possible only because of the unique patented extrusion process, which produces a consistent and measurable finished product. Laboratory testing has proven that the ceramic element will be safe to use, all the way to the element’s measured end-of-life.

Splash guard

The AquaRain™ Gravity Water Filter incorporates a unique patent pending feature. The upper vessel that holds the questionable water has a stainless steel splash guard formed on the bottom of the housing that will deflect splashed or overfilled water away from the lower storage area holding the filtered drinking water. Since frequent filling of the upper vessel aids in maximum production, the splash guard adds extra insurance to the daily operation of the AquaRain Gravity Water Filter.

Easy lift handles

Two solid stainless steel handles have been added to the upper housing to allow easy removal for cleaning. The handles have been spot welded to the container with a special computer operated system that controls the process precisely, forming a perfect welded bond.

Simple and reliable faucet

The lever-action faucet used on the AquaRain Gravity Water Filter is very easy to use with a simple push of the lever to draw a cup of clean water. The lever may also be flipped up to lock it in the open position for high flow dispensing of larger quantities of water.

Why YOU need the AquaRain Natural Water Filter

Is your water safe?

The quality and safety water supplies across the USA are not always to the standards we hope they are. Even when your city abides by the limits set by the EPA it can contain additives that may be dangerous or give your water an unpleasant smell or taste.

The AquaRain® Natural Water Filter is also the ideal answer to access to safe water during an emergency, requiring no electricity.



There is one thing you can count on, the contaminated water situation is not going to get better any time soon! The plain truth is that EVERYONE really should filter the water they drink, RIGHT NOW. The AquaRain® Natural Water Filter has been developed for just this very reason. Most importantly, the AquaRain® system produces safe drinking at the absolute lowest cost per gallon.

Here's how:

  • Advanced Ceramic Technology removes protozoan cysts and harmful bacteria.
  • Silvered Carbon Bed adsorbs pesticides, organic chemicals, chlorine, tastes and odors.
  • Energy-Free System operates by gravity and requires no power or chemicals.
  • Hard Ceramic Shell may be cleaned up to 200 times and lasts for thousands of gallons.
  • Attractive and Hygienic Stainless Steel Housing incorporates a unique "Splash Shield" flange.
  • Manufactured to NSF Specifications and meets USEPA Bacteria and Cyst Purifier Standards.

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 microfine 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 diatomes 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.
