The Katadyn series are excellent water filters -- I have one of the older generation Katadyn in my hurricane kit. My opinion -- the best water
filter is dependent upon the situation. If, for example, I wanted to go backpacking and wanted to filter my drinking water, then the Katadyn is my
first choice; The Berkey would be cumbersome to pack in this situation.
On the other hand, if a person is filtering ALL their drinking water, their cooking water and water for ice making, dedicating an hour or more every
day to pumping water through a filter is a definate drag. The Big Berkey holds 2 1/4 gallons, and is gravity-operated. Yes, it takes some time
for the water to filter down, but only seconds to fill it, leaving a purified 2 1/4 gallons for your use. That is my situation, and I can't
imagine anything better. As said previously, our water is rainwater collected from the roof, and stored in a concrete cistern. Are there frogs
or bugs in the cistern? Well, I hope not, and I clean it every coupla months, but I want to exclude all contaminants from our personal usage. You
know how the filters on the Berkey are tested? You put water tainted with food coloring in the top, and verify that the bottom purified water is
clear. I used a LOT of red. Food coloring becomes absorbed in solution and creates a molecule ever so slightly larger than a water molecule.
I think the best option of all is to have both. The Katadyn filter you linked is very impressive -- much more advanced than my older model. The
one you linked will filter 13,000 gallons with the same filter, and that's a huge leap from the one I have. They're not cheap, but what is the
cost of dealing with the sickness of having ingested cryptosporidium?
To me, Berkey is for regular life, and pump filters are for emergencies. Either can be adapted for either situation.
