Filtering Water in an Emergency - LisaJarratt - 12-02-2015
Building your own water filtration system.
I find it odd that they don't mention boiling your water, but I would do that too.

Sawyer .02 micron. Filters viruses and tapeworms and one filter lasts 1 million gallons.

Awesome! I was talking strictly in a "caught off guard" kind of moment.
Filters all the way! Be prepared!

I am in the water industry and I have seen a lot of claims on types of units and when I approach them they can't answer certain questions about water quality.

The article doesn't appear to indicate how much of activated charcoal you'll need. If I were going to buy some, who much should I buy? How many gallons can you push through this filter before you have to chuck the whole ingredients? Probably not too critical in measurement, but if say I was going to need to filter a weeks worth of water, would this "amount" be sufficient? Curious. I have a fancy Katadyne filter system and straws already.

Just bought this one for my son for Christmas.

This shows a big barrel. I don't think there is an exact science, in an emergency type of situation... if you didn't think ahead to invest in a filtration.

Still need a little disinfection. So use sodium hypo or a little bleach. Unless your filtering rainwater
RE: Filtering Water in an Emergency - LisaJarratt - 12-16-2015
Exactly. Need to boil it at the very least.

That's one of the things I was thinking. I have several types of filtering systems, not just for redundancy, but because they each do different things.
I originally bought the sawyer I mentioned because I was going on a back country trek through Isle Royale and that is the only place in North America you can still find tapeworms. The standard commercial filters are not small enough, so I needed the .02 micron.
The subject of the thread is good for an "emergency" where you were not prepared and needed to make a filter. But then again, you still need a container, sand, and charcoal. I am less likely to find those than I am my filters in my bug out bag.
RE: Filtering Water in an Emergency - ssphoto - 12-16-2015
I like this new diagram; thanks. I could use one of my rain barrels, I think.
RE: Filtering Water in an Emergency - bradberry - 12-17-2015
Dont forget to use washed sand.

The device i let my sone borrow(hopefully) creates sodium hypo chlorite. The one we bought him for Christmas, is a UV pen. Unless he filters it through some type of device he will still have turbid water. So we bought him a pump filter but i can't remeber the name of it. He works in the woods laying out logging roads and he wanted to have something light. He also has it when he goes to NE Oregon on his backpack elk hunting trips.
