Just, fiy, after I’ve done a bunch of research and discovery on water purification/filtration for the ‘prepared’ person...
Look into combining aggregate/charcoal on a home-built gravity rainwater filtration system. Unless you’re in a very dry climate, you want that ability first and it can be utilized secondarily for general water purification/filtration by manually getting the water to the top catch basin. You can find the designs on Youtube under ‘gravity water filtering’. IMHO, I would still purify the water before drinking (bird droppings being what they are).
Also fyi, the Berkey filters have a LOT more surface area for a similar price. I suppose it depends on what you’re putting them in (head pressure). The short/fat ones are more appropriate for 5gal bucket systems.
And since we’re on the subject, perhaps stating the obvious (or not)...bleach has a shelf life from the day of manufacture; don’t even think about storing it for emergency use. Stock up on powdered forms of water purification (calcium hypochlorite, iodine & the-like).
Thanks for the reply. (#34)
good point
Thanks for the Lifesaver mention. Might get a bottle for a bug-out bag and a jerry can for the house.
It's done by the Tribal government on request... Free even!
A gravity filter system can be made from (2) 5 gal buckets, a spigot and 1-5 Aquacera Ceracarbs or similar Doultons. Berkeys were good but had Q C issues.
If you live in a rural area you are 2 steps ahead of the game. In the urban areas the zombies will be trading their daughters for a bottle of water after 2 days.
Run your down spouts into 55 gal drums and save the water for irrigation, laundry and flushing the toilet.
Build bio-sand filter sand, gravel and activated charcoal from 5, 25 or 55 gal drums.
Find a local spring or have a friend that will let you have spring or well water. Pay to have it tested.
Household bleach can be used to kill biological contaminants.
Anyone have knowledge of/experience with a good water filtration/desalination system?
I am fully aware of the difference between bleach and calcium hypochlorite.
The numbers I posted earlier are from CDC and are for swimming pool disinfection, which generally uses calcium hypochlorite.
IOW, some organisms are highly resistant to chlorine disinfection.
This is a bit of a pet peeve of mine, as I acquired Giardia while backpacking in the desert, despite using iodine which is supposed to be more effective than chlorine disinfection against Giardia.
I can heartily recommend you avoid giardiasis. Cryptosporidium is even harder to disinfect using common chemicals.
Luckily, many of the common filters are fully effective against both parasites.
Yeah, I got something in the 70s in Algonquin Prov Park, probably giardia. Not recommended.
I have trouble believing a claim like that.
If it’s fine enough of a filter to filter bacteria, etc., it’s going to filter particles. You can’t clean all those particles out each wash. They build up eventually.
I used an MSR Miniworks filter in a large swampy area. It cleaned the water fine and I drank it with no problems. But filling each Nalgene bottle required breaking down the filter and cleaning it off. That’s the double-edge sword of a fine filter. No way it would have gone as long as they claim if I’d been filtering only that type of water.
A million gallons of dirty water? Hard to believe.
I have the same setup as you. Three thousand gallons is a believable life expectancy of any fine filter. Anything beyond that I’m leery of believing.
See my other posts. That would explain my doubtfulness on the million-gallon claim.
When it comes to drinking water, I want none of the living stuff and none of the dirty stuff (including oil and chemical runoff). I want clean, pure water.

tribal government? i dont have one of those
Berkey says the filters are good to 10,000 gallons, or more... I'm with you however, and will set these aside and install new filters on the next go around. Might try the ceramic filters we bought at half the price to see how they do. Fingers crossed!
LOL! Most folks don't!
Went Galt back in 2008, and moved to my better half's Reservation in N. MN. About 270 miles North of the insanity of the Twin Cities. Best move I ever made even considering the below zero periods...
A good water filter should also identify itself as a “water purifier” or “water purification systems”. A product cannot legally identify itself as a “water purifier” unless it has undergone rigorous 3rd party testing.
thats pretty far north... how are land prices up that way?
