Dan Is Correct for a Fixed loction where you KNOW there are no Chemicals or Viruses.
A Katadyne will do about 5000 to even 10000 gallons, to 0.4( ABSOLUTE ) to 0.2 (NOMINAL) microns.
A Katadyne "Combi" will also remove chemicals, but will not remove viruses.
A FIRST NEED Portable will do a minumum of 125 Gallons removing EVERYTNING and can be backwashed or gravity fed after that.
The BASE CAMP will do a minimum of 1000 gallons removing everything, and with replacable cartridges.
The Differance between these units ( Katadyne and First Need ) is simply what they will remove.
A First Need will go to 0.1 microns, removes all chemicals, radionucleotides, and viruses but for a lot less gallons.
Most Bacteria are what we are normally concerned with in a NON sit -X.
They are at least 4 microns across, but have learned recently to turn sideways and fit through a 1 micron filter pore.
A Katadyne will remove all Bacteria, and to a large amount of gallons.
The Question them becoms, how many Viruses or Chemicals are in my water, and how many will it take to make me sick?
I prefet to start out with the best, and replace the cartridges when the water is of an unknown source and chemicals may be an issue.
For viruses, I pretreat with bleach, then I can use an filter that has less performance in the Virus Department, allowing a lot more gallons to be
Its Up to you, and BOTH are Great for what they are designed for.
By the way DAN, I read your post last night about the Fish Punk, and I totally Believe You and I have felt that way too when confronted like that. I
understand your reaction and I would have done exactly the same.
I have had those feelings before, and I totally understand what you are going through. I almost U2U' ed you last night to let you know, but I want to
finish the thread. I was sirected to it by another Member who sees coincidences in ""OUR"" experiences.
What bothers me is the 'back to sleep feelings' that you or I could not fight. I have had those more times than I can even begin to count, and I
wonder the same things that you do.
There is a connection there, and I will try to finish the thread this evening.
I got to about page 10 on ATS.
I followed every emotion you conveyed by Memory and flash back, and your not alone in your experience. You just got in quite a few more Hits... than
I ever did. I can remember 3 or 4 before I 'knocked out', with no weapons myself, just hands and feet. I actually broke my elbow one night doing it,
and had a real difficult time the next day putting all the pieces back together as to what happened. It still hurts like hell today when I bump it.
I did it intentionally to make myself remember what was happening.
VERY FRUSTRATING to FEEL that "OFF SWITCH" that they can use on us.
