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

Ü 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.

Ü 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.

Ü WEAR GAUGE 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.

Ü SPLASH GUARD: The Aqua Rain™ Gravity Water Filter.

Ü 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.

Ü SIMPLE & RELIABLE FAUCET: The lever-action faucet used on the Aqua Rain 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.
