So far we have looked at these two models, recommended by Bradt guide
MSR® MiniWorks™ EX Microfilter.

Thanks!

You can't go wrong with the Katadyn pocket filter. It's ceramic filter is good for 50 thousand liters or so. I have used mine in remote area's i North America and although water is generally good bacteria are bacteria no matter where in the world you are.
Good luck shopping for what works best for you!!

I have a Katadyn as well. Carried it on the motorcycle for a year, around the Annapurna twice. Would not dream of trying anyhting else. It's small, really well built, filters a liter a minute, no taste residue, 0.2 micron, lasts forever (ceramic filter can be cleaned with a simple spunge or old tooth brush). Not cheap at $300 or so, but one of the best pieces of kit I have.

I use the Katadyn Pocket as well. Great bit of kit.

However make sure you pack it well. A hefty drop and a cracked filter (as its ceramic) will effectively mean its useless until you replace the filter. Thankfully the filters are cheap.

Alternatively just drink bottled - water is vastly overrated :-P

Sophie, we did an exhaustive review of water treatment systems in our Fall, 2009 issue, using clinically contaminated water and laboratory evaluation. It's worth the read as it covers all aspects of what a traveler needs to know regarding waterborne pathogens.

I like the Katadyn Pocket Filter a lot. It's slow, but reliable. The First Need XL and Sweetwater are also good choices. Watch out for the UV systems, whether the leave-it-in-the-sun variety or more sophisticated.

I have also been looking at this for a trans Africa trip (www.pictureafrica.org) and found this little Gem... Vending Machines - RO Water - Table Mountain Aquavend (P008 model)

There is very little information on the website. I did manage to get a PDF out of them and it compared on par with a few devices that are more than double the price.

I bought one for around GBP 200 and it is good for 4 000 liters without filter change....

Steripen

What about the STERIPEN, this is a bit off topic cos i am riding a bike and space is a bit of an issue.....i'm thinking of using the steripen when you go to a resturant in a little town in south america or when camping in the amazon....would it work as good as the miox pen???

pumps need to be washed with sterilyzed water otherwise you'll kill their porpouse, but they do give you clean water faster than thos pens, pens need batteries, pumps dont......the STERIPEN will work for about 5000 L if i'm correct....just add batteries.....the MIOX pen needs batteries and salt and those testers.....

many many option to choose from....

i'd say for a daily use i would use the stripen.....and for the big tank in your car a one of those nice pumps....perhaps use the pumps to clear that 99% and then hit the plus 1% with the pens! !!



enjoyyyy! !
Matteo!! !

Steri Pen

I will be using a "Steri-Pen". It is standard issue for military. A simple device with AA batteries (in which you can find anywhere recharge). It won't filter, but it uses UV light to kill everything in the water. Great for when you have questions about the beverages you are being served. Just stick it in the glass for a minute or so. You just might have to drink some dissolved or suspended solids. Extra flavor. Comes with simple prefilter screan and bottle with adapter. It comes with a prefilter that adapts to a bottle. If the military trusts it?

I used a Katadyn filter in the Himalaya and never had a problem. On a previous trip I relied on boiled water and ended up with Giardia an anerobic bug with what can only be described as catastrophic consequences and can take three months or more to shift ,believe me, not pleasant.


I know Katadyn filters are expensive but after having Giardia I know you pay either way... from experience I prefer the cash alternative, enough said!!

My wife and I got amoebic dysentery in Senegal once. Would have loved to have something so I didn't have to go out. I've got a steripen now. Nice and small and not as easily damaged as ceramic filters. Plus very small. I've been taking the hiker for ages but it's always just sat there waiting to get used. Growing mould in the mean time. If I would be backpacking I'd take it over the pen, but on the bike you always have power to power it. Although it's more a mental thing, as hopefully it won't need any use. Still though, better safe than sorry.

I though that if you properly boiled water, its IMPOSSIBLE to get giardia ???????

Did you thoroughly boil it ?? A proper rolling boil for 2 mins or more ??

At altitude water boils at a lower temperature. Extended cooking times in the oven and pressure cookers are common for folks who live at high altitudes (I live in the mountains of Colorado in the US). This might explain the boiling issues in the Himalaya. It's not so much the boil but the water temperature. Just a thought. Dave. PS, I just buy mine!

The vast majority of pathogens are killed long before water reaches boiling temperature. By the time water reaches boiling temperature, all of the pathogens are dead. Even milk is pasteurized at only around 70 deg.C.

So except at extreme high altitudes, boiling water for one minute should be sufficient to kill all microorganisms.

From http://www.princeton.edu/~oa/manual/water.shtml:

Quote:
Boiling is the most certain way of killing all microorganisms. According to the Wilderness Medical Society, water temperatures above 160° F (70° C) kill all pathogens within 30 minutes and above 185° F (85° C) within a few minutes. So in the time it takes for the water to reach the boiling point (212° F or 100° C) from 160° F (70° C), all pathogens will be killed, even at high altitude. To be extra safe, let the water boil rapidly for one minute, especially at higher altitudes since water boils at a lower temperature
Growing up in Colorado, I hiked extensively at high altitudes and relied on my Katadyn filter. For some parts of the world, I'd probably filter first then boil the clear water to be paranoid-safe. Using iodine tables is also another option, but the tablets make the water taste funny.
