Product Description

Product Description

No pumping required - water container with built-in ceramic filters. Used and trusted by relief agencies around the globe for many years.


The Katadyn TRK Drip Ceradyn free-standing gravity filter features a 10 liter water container for large quantities of water. It's ideal for the water supply for camps, cabins and homes without running water. This Ceradyn version comes with three ceramic filter elements.

Ceramic filters have a micro porous structure with impregnated silver which delays the growth of bacteria. The pore-size of Katadyn ceramic filters is 0.2 micron (0.0002 mm). Bacteria range in size from 0.2 to 5 micron and, like protozoa (1 to 15 micron), are efficiently filtered out. Ceramic filters can be mechanically regenerated and the filter capacity is measurable.


  • Technology: 0.2 micron ceramic depth filter
  • Output: ca. 4 liters/hour
  • Cartridge Capacity: Up to 150'000 l (depending on water quality)
  • Weight: ca. 3.3 kg
  • Size: 25 x 45 cm (9.8 x 17.7 inches)

Why Treat Water?
A crystal-clear stream or lake usually contains microorganisms that can make you sick. Water contaminants like protozoa, bacteria and viruses, can cause serious illness. Optimize your travel preparation and use a portable drinking water system from Katadyn.

I will buy another in a heartbeat when this one is done!!!!

After the first day or so the water filtered more quickly, having worked its way through the new filters.

So you can take the brown sludge, filter it and it will taste like good ole water.

I have used the Ceradyn Water Filter in Ghana, West Africa for the past seven years. It has performed very well, filtering up to 3 gallons a day. I clean it periodically with a moderately abrasive pad. Green algae grows on the filter after the top-fill container drains into the lower one. It cleans up well and I have added a little chlorine at times to cut down the problem.
People who are considering such long time use of a water filter should not purchase the Gravidyn Water Filter because the effective life span of the central charcoal core is only six months. When I call Katadyn about its effectiveness past six months, they warned me that the charcoal core could develop mold after that time and is impossible to clean effectively. So I am purchasing a new Ceradyn filter for our up-coming work in Liberia.

I was looking for an means to ensure I could have a sustained source of potable water. I have a portable Katadyn for times I'd have to relocate to a temporary shelter. But, for home, which is where I tend to stay, if at all possible, I wanted a long term solution to this goal. I thought of a water bladder but anything over 200 gallons gets rather big. A filter seemed to be the best solution. I may still need a means of storage, but even that can become contaminated with bacteria and possible other nasties.

There are TWO models of this filtering system, and it is CRITICAL to understand the differences, because they are identical containers from the outside: Its the ceramic filters that are different between the Ceradyn and the Gravidyn.

The The Ceradyn can filter up to 39,000 gallons. The Gravidyn filters must be replaced when they are 6 months old. Both of these filters can produce up to 15 gallons / day with clear water. (The more solids in the water, the slower it filters the water.) So.. at BEST the Gravidyn will filter 2,790 gallons before the filters have to be replaced. This is because they have a core that is made of activated charcoal and can start to grow bacteria. Since the charcoal is past the ceramic filter section, the bacteria can re-contaminate the filtered water.

That is a big difference: 39,000 (Ceradyn) vs 2,790 Gravidyn) gallons. In fact, at 15gal/day, the Ceradyn will last a little over 7 years (filtering clear, low particulate water.) The point is, one is a long term survival tool (Ceradyn) and the other is a short term survival tool (Gravidyn).

The Gravidyn has an important ability the Ceradyn does not have. The Activate Charcoal absorbs odor, bad taste, and some chemicals.

I live in South West Florida. District Water Management officials insist on allowing less-than-healthy water to be provided since we are in a drought. It is un-nerving to have to look at one's water every day and wonder what's in it.

Since I have had this Katadyn Drip water filter in my home, I have had complete confidence in what I am drinking and what I am making my pets drink.

I bought this filter system after doing tons of research. It is the only one where you are not enslaved to some company in having to buy their expensive new filters every 6 months. I detest companies that enslave their buyers with the need to purchase expensive items in order to use the initial purchase (for instance Epson computer printers, as well as most other water filter companies).

I also learned that this filter is used around the world and sits on the kitchen counters of homes all around the world because it works. It is passive and reliable. The filters it comes with are good for so many gallons that it is amazing and gives one a good sense of having a very good water filter. In this day and age of poor Water Management and the prospect of intense storms and hurricanes that might effect water supply, this filter is perfect.

I called the manufacturer and they advised cleaning the three filters when you first get it to wipe off any dust. Then just set it up, very simple and a child could do it. At first the drip was so slow I thought I'd be waiting a life-time for a cup of water. But it speeds up overtime and it is easy to keep a good supply of clean water at all times. You get used to seeing the big friendly white elephant on the counter-top. Especially because you know it is full of healthy, drinkable and reliable water.

My wife and I took our Katadyn TRK Drip Ceradyn Water Filter to Uganda a year ago and have been 100% happy. Sure, it is not pretty, but the water is great! Before getting it we would have stomach problems from the local water, but no more. Nor are we dependent on local bottled water, which is not all that reliable (is it anywhere?). We went with the Ceradyn filter, although it does not improve the taste all that much, because we knew the water would be pure and drinkable. After running it through the Katadyn we put it through a Brita filter to improve taste. Having said that, the Katadyn taste is actually quite good. I will buy another in a heartbeat when this one is done!!!! And if we ever move back to the US I'll get one to ensure the water is healthy. Highly recommended.
