Gravity Natural Water Filters - the best survival tool ever!

Made in USAMADE IN USAMade in USA

How The Gravity Filters 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.

Laboratory Testing

Extensive independent testing is the key to proving the performance of any water filter product. The ceramic filter elements used in the AquaRain Gravity Water Filter have been thoroughly tested by government agencies and independent laboratories. Our unique ceramic structure has been successfully tested in independent laboratories with Cryptosporidium parvum for cyst removal, and the EPA mandated Klebsiella terrigena for bacterial removal. These elements have also been successfully tested against the Health Industry Manufacturing Association’s test organism, Brevundimonas diminuta, which is approximately one-third the size of the EPA bacteria test organism.  It is notable that all of these tests were performed at 60-90 p.s.i. which is far above the very low ½ p.s.i. found in our gravity operated system.  This equates to an expected performance in microorganism removal far beyond the results already achieved in our laboratory testing.

What is particularly noteworthy is that all of the above laboratory tests have been performed with fully expended elements, ready for disposal. All components for testing were abraded to 10% below their end-of-life tolerance and then exposed to contaminated field water prior to being challenged in laboratory testing.  In every case, AquaRain Ceramic Elements surpassed the stringent EPA standards for a bacteria and cyst purifier.

We have gone the extra mile to insure that our product will perform as promised and remain effective in producing safe drinking water throughout its entire life. To the best of our knowledge, no other manufacturer has dared to test in this way and publish the results of this type of end-of-life testing.

Product Innovations

AquaRain 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 AquaRain 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 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

Testimonials

"Although we have a well, the health department advised us to not drink the water. When we first heard of the AquaRain Water Filter System we were skeptical but bought the unit anyway. You people were very helpful and the product arrived in a very timely manner. (Of course we never told you that we were going to give the unit ‘the acid’ test!) Needless to say, we were ecstatic when the water test came back with a green light for drinking water from our very own well! Thank you, AquaRain. Please send us four more filters…we are believers!" WG from Lenexa, Kansas

"Just had to tell you people how much we appreciate you. The filters I ordered for our AquaRain came so quickly. Thank you so much. My neighbor is convinced that her health has improved since she is now drinking water from her AquaRain. We all love our water!" MW from Windom, Texas

"The water from my AquaRain tastes just like the sweet, spring water I used to drink when I was a kid. I love it…thanks again." CG from Bakersfield, California

"I saw, and used, your product when I was visiting a friend who lives in Sangolqui, Ecuador.  He is an American physician who runs a small clinic there.  He had nothing but great things to say about his AquaRain filter.  I didn't think I would need one here in the states, but the drinking water here in San Diego isn't very tasty, to say the least.  I look forward to getting my AquaRain filter and enjoying a safe supply of water, no matter where I live." DC from San Diego, California

"I purchased an AquaRain Model 400 Water Filter as a Y2K investment seeing as the Lord caused me to move to a lakefront lot 4 years ago. I thought this would not only afford us food to eat (fish) but with this filter also drinkable water. Further, the manufactured housing community in which I live affords us water that is horrendous to the taste, sight and smell. As soon as the AquaRain arrived, I began using it to filter the house water. The taste is delicious. Thus far, four friends have expressed interest in having one for themselves, one having already purchased it.

The question arose, how could I be absolutely sure the water was safe to drink if I took it from the lake? So I decided to put it to the test. I took several samples to Turner Technologies of Warsaw, Indiana. …..time and again the tests came back that the AquaRain did its job. I thought you would like to know. I am also sending a copy of the results to ……. My grateful appreciation to you for providing a tremendous product that really works." RH from Warsaw, Indiana.

"Thank you for the AquaRain water filter. It is very nice. I put it together last night and this morning we had water! We are always amazed at the ways that the Lord meets our needs—even through people we don’t know and have never even met. Our prayer is that God will richly bless you for your generosity toward us." M & P from Baratillo, Mexico.

"We are enjoying our AquaRain. The water tastes so good! It sure beats the Pur faucet water filter we had. Thanks again for a great product. We are recommending it to friends and family. Hope you’ll get some more sales." JW

"I’m writing to let you know how thrilled we are with our new Aqua Rain gravity fed water filter. We recently had a hand pump installed on one of our two wells and decided to have a water test just to make sure the water from that well was suitable for drinking. The person who built the house and owned the property originally told us they used this well the entire time they lived here and it was good for drinking. They sold the property and the new owner had another, larger, well installed and the original well was not used for several years until we bought the property and had the hand pump installed on it. This is the reason we decided to have a test on it to make sure it was still drinkable.

Imagine our surprise and dismay when the test came back negative, saying the water had coliform (bacteria) and was unsuitable for drinking. I mentioned this to a friend and she told me about the AquaRain water filter, which we subsequently purchased. I am enclosing the two tests we had done after receiving the Aqua Rain; one with water taken directly from the well without being run through the filter, which indicates a very high coliform count, and the other with water from the well run through the AquaRain water filter, which came back absolutely clear of any coliform bacteria. We were so thrilled. Not only did it filter out all the bacteria, but it also tastes wonderful. Thank you for your fine product." PG from Churubusco, Indiana

F A Q

Question: How much water will the AquaRain® Natural Water Filter produce?

Answer: Our factory testing has established a water production rate of approximately one gallon per hour for the AquaRain® Model 400. This maximum production figure has been established with clean fully wetted elements and relatively clear water. Keeping the upper vessel as full as possible, perhaps refilling every fifteen minutes, is essential to reach the maximum production potential.

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.

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.  Proper cleaning will restore the filter to full flow rates, each and every time.

Question: How long do the filter elements last?

Answer: There are two parts to the filter elements; the ceramic shell, and the granulated carbon filling. Cleaning of the ceramic shell is what wears out the ceramic portion of the filter. Over time, particulates and bacteria clog the microscopic pores of the ceramic, slowing down the flow rate. Occasional cleaning with a small brush or the enclosed green scrub pad will restore the original flow rates. Eventually, cleaning of the ceramic will wear the walls down, making them thinner.  When the attached gauge can fit over the diameter of the ceramic, you know it is time to replace the element.  Our ceramic formulation is very hard and will endure many cleanings, perhaps over 200 if moderate care is taken and light pressure is used.  In normal usage this equates to thousands of gallons of water that can be filtered.

The inner carbon filter works by adsorbing and/or reducing certain chemicals, and has a finite lifetime based on the concentration of the compounds being reduced. Generally speaking, the carbon capacity should exceed the life of the ceramic portion of the filter when processing water from most sources.  Annual replacement of cartridges should guarantee sufficient carbon capacity for maximum protection.  Please note that should the carbon become exhausted, that the elements are still fully effective for the removal of protozoic cysts and harmful bacteria, provided the remaining ceramic wall thickness still has useful life.

Question: How do you clean the ceramic elements?

Answer: The ceramic elements are very easy to clean. You simply remove them from the upper container, and while holding the threaded end of the filter upright, brush lightly downward toward the end cap.  After you have lightly cleaned the surface, simply rinse and reinstall the element . Occasionally it will be necessary to lightly abrade the surface with the supplied green pad to restore full flow rate, perhaps after 3 to 5 brush cleanings.

Question: How do you store the filter system?

Answer: If you wish to store the AquaRain® Natural Water Filter, simply remove the filter elements and allow them to completely air dry for at least 24 hours or more. Dry the containers and all parts, then slide the lower container into the upper container to nest them together for compact storage.

Question: Has the AquaRain® Natural Water Filter been laboratory tested?

Answer: Extensive independent testing is the key to proving the performance of any water filter product. The ceramic filter media used in the AquaRain® Natural Water Filter has been thoroughly tested by independent laboratories and government agencies. In fact, an especially difficult testing program has been used where expended "worn out" elements have been tested to positively demonstrate that the ceramic elements remain fully effective throughout their entire life. To the best of our knowledge, no other manufacturer has dared to test in this manner.

There still remain special additional state testing and filing requirements as yet not completed that prohibit us from making specific health claims in the states of California, Iowa or Wisconsin

AquaRain Water Filter System…MADE IN AMERICA. There IS a difference!


What is the difference between the AquaRain System and the British Berkefeld?

The British Berkefeld water filter is a system that relies on ceramic technology originally developed in
England over 100 years ago. Recently, Fairey Industrial Ceramics, manufacturers of the British Berkefeld
water filter system, licensed use of the name “Doulton” for use in their line of small consumer ceramic
cartridges. The slip-cast method of production currently used by Fairey is well suited for lower
performance, cost competitive industrial ceramics, but may lack the consistency and reliability needed
for truly safe household water filtration. Their large, room-sized kilns have a tremendous volume capacity,
and for sheer quantity and low cost, they cannot be beat.

CERAMICS: The American-made ceramics used in the AquaRain system are produced in very
small batches and are individually tested twice before leaving the factory. The patented extrusion
process used to produce the AquaRain ceramic results in an extremely uniform product. (Side by side
the visual differences are great…the British ceramic appears bumpy, white, soft chalk-like; while the
AquaRain filter is smooth, hard and uniform.) The use of small, computerized kilns insures the
unsurpassed consistency and reliability found in the American-made AquaRain ceramic. The ability to
accurately measure a filter’s remaining wall thickness and thereby safely determine when the filter has
reached the end of its useful life is another major difference between the two filter systems. The AquaRain
system provides a simple measuring gauge to determine the thickness of the ceramic wall. Over time,
the cleaning of the ceramics will cause the ceramic wall to become thinner. The end-of-life-gauge
provided with the AquaRain takes the guesswork out of when to replace the element. Literature included
with the British Berekfeld unit specifies that the ceramic elements should be replaced at six-month
intervals, although salespersons for the imported unit will sometimes tell their customers that they can
use their elements until they crack. This can be very dangerous. Since the wall thickness has a great
effect on the performance of the filter, elements thin enough to crack are simply unsafe.

CARBON: Granulated activated carbon (GAC) is indeed a mighty product for adsorbing impurities
found in water. It is said that one teaspoon of granulated activated carbon has the adsorptive area
equal to the entire surface of a football field! Pesticides, chemicals, chlorine, MTBE, as well as other
contaminants too numerous to name, can be adsorbed by GAC. The AquaRain water filter system
incorporates pure coconut shell carbon that has been proven to have superior performance over the
bituminous coal based carbon used within the Doulton ceramics in the British Berkefeld unit. The reliability,
long lasting nature, and efficacy of a coconut shell carbon has been found to be superior to a coal base
carbon.

SILVER: Metallic silver has been added to the Doulton ceramics used in the British unit to combat
“mitosis” or the growth of bacteria through their ceramic walls. This precaution is necessary as the
holes of their ceramic pore structure are large enough for bacteria to grow in. The AquaRain ceramic
pores are far too small for bacteria growth, alleviating the need for silver within the ceramic. However,
all filters with GAC filter beds should use silver to inhibit bacteria growth within the damp environment
found there. The AquaRain system incorporates a small amount of metallic silver where it belongs,
within the GAC filter bed.

PORE SIZE OF CERAMICS: The “absolute” micron rating of the ceramic found in the imported
British Berkefeld water system, as stated in their published specification sheets, is .9 micron. The
“nominal” rating of the Doulton ceramic is listed as .5 - .8 micron.

What is the story of micron ratings?

There is a great deal of confusion regarding “absolute” micron ratings. Just how much of a reduction
efficiency should be considered adequate for an “absolute” rating? Is 99.9% (3 log) sufficient, or would
99.9999% (6 log) be more appropriate, since it matches our American EPA bacteria requirement? Should


a filter be rated by its ability to remove particulates of a certain size, or should it be challenged with live
organisms of a similar size? Should a filter be tested only when it is new, or should the ratings be based
on its end of life performance? Unfortunately, the fact is, there is no industry or government standard for
“absolute” filtration efficiency.

The ceramic filters used in the AquaRain Gravity Water Filter have been extensively tested against
live organisms using fully used and expended end-of-life elements. We believe this form of testing to be
the most stringent, since it tests the filters in a manner similar to the way they would actually be used
under worst-case conditions. When tested against the .5-.6 micron organism Klebsiella terrigena, the
EXPENDED ceramic elements demonstrated a 6.6 log reduction (they achieved 8.9 log reduction when
new). The EPA requires a minimum 6-log reduction (99.9999%) from NEW elements, which was greatly
exceeded with used elements under extreme pressures of up to 90 psi, well above normal test pressures.
At the very low pressure of ½ psi found in our gravity system, the efficiency would be far greater still.
Our ceramics have also been tested against the much smaller Health Industry Manufacturing Association’s
test organism, Brevundimonas diminuta, and achieved a 99.9999% reduction (6 log). Since this organism
is .2-.3 micron, should we claim this as our “absolute” rating? Here is where it really gets confusing. In
another test, expended ceramic elements were challenged with MS2 colophage virus and achieved a
99.999997% (7.7 log) reduction against this organism that is less than .1 micron. Could we now be
considered “absolute” at less than .1 micron? The British Berkefeld literature states filtration rates of .2

- .9 microns depending upon efficacy levels achieved. (95% - 99% safety levels) Thus, this issue can be
quite confusing to determine the actual filtration achieved by the British unit. The bottom line is that the
filter elements used in the AquaRain system out perform all other ceramic filter elements available.
Since there is no standard for “absolute,” YOU will have to decide what level of protection you want for
yourself and your family.
FILTRATION RATE: The filtration rate between the AquaRain and the British Berkefeld is another
area of difference. It is true that water will filter faster through the British Berkefeld than through the
AquaRain system. Unfortunately, dealers of the British system represented this as a negative feature of
the AquaRain. Of course, this claim does not make any sense! Since the pore size of the British
ceramic used in the imported product is larger than the AquaRain ceramic, water will indeed filter faster,
but also allow more contaminants through! Additionally, as water passes through the bed of granulated
activated carbon, the contact time is longer in the American made ceramic, which is essential for adsorbing
contaminants from the water. The bottom line is that the AquaRain system can produce far more high
quality water a day than a family possibly may ever need. So the question is…what is more important,
quantities of lower quality water or the ultimate quality of the AquaRain process?

LONGEVITY: The overall life of a ceramic filter is directly determined by its cleaning. When the
flow rate through the wall of a ceramic becomes objectionably slow, the surface is lightly cleaned to
restore full flow. The British ceramics used in the Berkefeld system are soft, chalky and wear away
quickly when cleaned. Additionally, they are asymmetric and non-concentric, preventing the measurement
of the remaining ceramic wall following a cleaning. There is no way to know when the filter cartridges
are worn out! To combat this deficiency, the British system includes instructions to replace the ceramics
every 6 months.

The American-made ceramics used in the AquaRain system have been manufactured to be very
hard with a tight and controlled pore structure. This has been accomplished through careful formulation,
a patented extrusion process, and precise firing in small, computerized kilns. These ceramics will
accept up to 200 gentle cleanings and potentially last for several years. For unprecedented longevity
and the lowest operating cost of ANY filter system available, the AquaRain is the answer!

STAINLESS STEEL HOUSING: Our stainless steel housing is seamless and smooth edged, being
formed from single sections of #304 (18-8) heavy stainless steel sheet. We have also incorporated a
“Splash Guard” system to insure safe daily operation and convenient carry handles. Our system holds
three gallons of water, allowing for fewer fillings for maximum production, and has a simple and reliable


lever-action faucet. The British Berkefeld uses a less expensive process of rolling & welding and may
have leaks or voids where bacteria can be trapped. The British system also has no overflow safeguards,
no handles, and a “tap” or faucet that is difficult to use.

USEPA PURIFIER STANDARDS: The following is a very important outline that addresses some of
the differences between the AquaRain water filter system and the imported British Berkefeld unit, along
with a short general description of the EPA testing requirements for water filters.

The United States Environmental Protection Agency (USEPA) has established a testing methodology
(protocol) for water filters (purifiers) which establishes minimum levels of performance for removal
(reduction) of the three classes of pathogenic organisms, protozoa (cysts), bacteria, and virus. This
testing procedure with associated required minimum performance levels is known as the “USEPA Guide
Standard and Protocol for Testing Microbiological Water Purifiers.” These testing procedures, which are
performed by independent laboratories, must follow the testing “protocol” established by the USEPA,
which establishes the conditions for conducting the various tests with the three classes of organisms
(such as number of gallons of test water, test water ph levels…etc.) The “standard” establishes the
minimum levels of reduction performance for each class of organism along with which particular organism
is to be used for testing in that class. When a microbiological water filter has demonstrated the ability to
inactivate or remove at least the minimum required level of the mandated organism for a particular
class, using the USEPA established testing protocol, the manufacturer may then claim that their filter
meets the USEPA standard for that class. When a filter manufacturer meets the removal standard for
all three classes of organisms, it can claim the overall title of Microbiological Water “Purifier” for that
water treatment device.

CYSTS: Even though the Doulton Super Sterasyl ceramic “candles” used in the British Berkefeld
gravity water filter have not been tested in strict in accordance with the USEPA guidelines, we believe
that they will probably meet the minimum standards for cyst removal only when they are in NEW condition.
Since there is no safe method for determining when these “candles” have stopped meeting at least the
minimum USEPA performance level, you cannot be certain that you are protected except with relatively
new “candles.” Doulton (the manufacturer of the ceramics used in the British Berkefeld unit) attempts to
compensate for this exposure to failure by recommending replacement of their Super Sterasyl filter
elements after six months of use.

The ceramic elements used in the AquaRain system have fully met the USEPA requirements for cyst
removal, demonstrating full compliance not only when they are new, but also at the measured end-oflife.
This assures the user that the filters are safe to use throughout their entire life and that you can
know with confidence that they are still fully effective when it is time to replace them.

BACTERIA: There is a MAJOR difference between the filters found in the British Berkefeld unit and
the AquaRain water filters in this challenging area. First, we will examine the performance of the AquaRain
against the bacteria class of organisms.

The filter elements incorporated in the AquaRain filter system have exceeded the USEPA removal
requirements for the mandated test organism, Klebsiella terrigena, having been tested by reputable
independent laboratories using the established USEPA testing protocol. As with the Cyst test results
above, the elements have demonstrated full compliance with USEPA standards for bacteria removal,
even when abraded down to minimum end-of-life wall thickness. These “end-of-life” test ceramics were
even exposed to field water from natural outdoor sources, so they would more closely approximate a
customers expended elements ready for disposal. The end-of-life testing regime, while not mandated
by the USEPA (which allows the submission of new components), assures the user that our filter elements
high level of performance will be maintained throughout the entire useable and measurable life of the
filter element.

The simple truth is, the Doulton Super Sterasyl ceramic “candles” used in the British Berkefeld gravity
water filter do not meet the minimum standards set by the USEPA for bacteria removal. The USEPA
standard for bacteria is removal of >99.9999% (6 log) of Klebsiella terrigena with a new filter element

The Original water Purifiers:
http://www.biznet1.com/waterpurifiers/

tested in accordance with the USEPA methodology and procedures in an independent laboratory. Both
the factory literature for the British Berkefeld gravity water filter and the Doulton factory literature for the
Super Sterasyl ceramic filters extol a removal efficiency of only >99.99% for Klebsiella terrigena. This
falls far short of the >99.9999% removal as mandated by the USEPA testing standards. The bottom line
is that the imported British system does not and cannot meet the USEPA standards for bacteria removal
by a water filter. In fact we can find
NO OTHER GRAVITY WATER FILTER THAT CLAIMS TO MEET
THIS USEPA STANDARD!

VIRUS: No pressure free, chemical free gravity water filter has ever passed this testing standard…YET.
AquaRain is committed to meeting the challenges of producing a ceramic gravity water purifier that
meets the fullest extent of the USEPA testing protocol AND doing so with expended end-of-life elements!
Preliminary testing with MS-2 Bacteriophage virus has given great encouragement and specific direction
to our engineers towards the development of a patentable product that will truly be an earthshaking
breakthrough in ceramic water filtration technology. Until that day comes for official water purifier status,
we can confidently say the AquaRain Water Filter System:

“Exceeds EPA Purifier Standards for
Bacteria and Protozoa Removal”

The bottom line is that the AquaRain Gravity Water Filter meets the fullest extent of the USEPA water
purifier standards for removal of cysts and bacteria, and does so even when the elements have reached
their end of life. It is not surprising that our American Made system is the only one that meets our own
country’s challenging American Standards!

AquaRain Water Filter System: MADE IN AMERICA.
There IS a difference!



What is the difference between the Katadyn and the AquaRain?

The Katadyn TRK Gravity Water Filter is a very good filter and the ceramics are top notch. The
Ceradyn ceramic filter elements used in the TRK have an end-of-life gauge similar to ours and are of
similar hardness and overall quality. There are several important differences however. Here are a few...

The AquaRain ceramics have a smaller pore size than the Ceradyn and a correspondingly higher
performance in removing smaller pathogens. The Ceradyn elements are filled with a silvered quartz
gravel which will not improve the water quality in any way, while the AquaRain elements are filled with a
high quality silvered granulated carbon made from coconut shell that demonstrates a superior performance
in reducing pesticides, various chemicals, chlorine (if present), halogens, pesticides, tastes and odors.
Katadyn has recently introduced the Superdyn cartridge, which is filled with a bituminous (coal) carbon
filling. Bituminous carbons do not typically have the VOC reduction performance of coconut shell
carbon, as used in the AquaRain Gravity Water Filter System.

The rugged yet attractive AquaRain housing is constructed of heavy duty 18-8 stainless steel while

the Katadyn TRK is made of more difficult to sanitize plastic.
Lastly, the imported Katadyn system uses only three ceramic elements and costs FAR more than our
AquaRain Model 400 with four high quality ceramic elements in a stainless steel housing.


Will the filter elements designed for the AquaRain System fit into the housings and replace the
British Berkefeld and Katadyn filter cartridges?

Yes, the elements may be used as high performance replacement cartridges for both of these gravity
water filter systems. The elements mount in the housings in the same manner as the original filter
cartridges.
