Hi All, for those interested, I have come up with a water filtration system that can be used as a gravity filter or like a filter-as-you-go hydration system. Either way, NO PUMPING REQUIRED! Check out the video: http://www.youtube.com/watch?v=wSYWoplv_Uo

Jason,

I was unable to get the link to work!

The link worked for me.

If I were going to double treat my water (filter and chemical), I would filter first and then add the chemical.

Nice job Jason! Your video was straight to the point, easy to understand and informative. I have to Frontier Pros that I have used and never thought about taking off the bite valve and use as a gravity feed filter. Awesome. Great job!!

John, can you try it again? It's also on my blog if youtube doesn't work: http://jasonklass.blogspot.com/2008/09/my-new-water-filter-design.html

Great idea! Thanks for sharing. I plan to order the filter and give it a try.

Jason,
Nice clip. This shows just how easy gravity can be.
Kudos to Ben on the hacked Platy idea. I've got this setup minus the scoop (been using my 600ml mug) and the hang cord.

treat first then filter on 09/03/2008 20:50:39 MDT Print View

A couple of insights:

1. This filter has charcoal in it which means treating first, filtering second is the right way to go. Treating kills the "small stuff" or viruses, then filtering removes the "big stuff" and the charcoal removes the chemicals that have already done their job so you don't have to drink them.

2. Since the charcoal removes the chemicals, there's no point in using expensive tablets. Unscented chlorine bleach will kill viruses in about half an hour. 3 drops per liter of clear water, 5 drops per liter of cloudy water. Once it's done it's job, you run the water through the filter and the charcoal removes the bleach and you get purified, fresh tasting water.

Love the Sitar!

Another great hit Jason.

Another fine, adaptive use of ultralight products. And another well-produced, informative video, Jason. Thank you.

Great job Jason! Quick question - considering that the water in the dirty bottle is "treated," is there a chance you might use it as a clean bottle if the need arose? Being new to backpacking I am wondering whether the rules of common sense say to always treat it as dirty, regardless?

John:

That makes perfect sense from a pure treatment perspective -- except for those of us who can't stand that awful swimming pool taste (subjective, of course). For us, it's better to treat with chemicals first (to kill the small stuff like viruses and bacteria) -- then filter to block out the bigger, harder to kill stuff like cysts -- and also to remove the offensive chemical taste.

Hi Greg,
Yes, I think you could as long as you don't mind drinking particulate matter. That's another reason I like the filter--it takes out anything that's floating around. Also, you would probably want to wait the full 4-hour time to make sure even the big stuff is dead before drinking it.

I checked out the Aquamira filter. It's only 3 microns. That doesn't compare well with say, the claimed sub-micron capability of the Miniworks.

Of course there is a dearth of actual testing that would say this matters. I sure would like to replace my heavy Miniworks with this little thing, but the doubt lingers.

Herman,
That's a choice to make in the gear you use. Filter it all, or filter out the big stuff after chemicals killed the little ones? Everyone has their own preferences.

Or use UV, kill ALL the bugs, and get no bad taste.

Yeah, except 3 microns isn't small enough to filter all the big ones.

What is smaller than 3 microns that the chemicals won't kill in 30 minutes?
