i-Straw Water Purification

[LocalYokel]

These seem pretty handy. Purifies 500 litres from 99.9999% of waterborne nasties... a new addition to the kit bag or a gimmick? What do you think...?

If you follow the suggestions from "Smarty" at the Wilderness Gathering, then I think that any method other than boiling is not likely to be 100% effective. My interpretation of his advice is that if you have the time, then boil the water...

...so although I have no experience of the 'straw' myself, I'd probably be a little bit sceptical. If it is only a filter membrane, then some stuff may well get through it (e.g. viruses). If it uses chemical disinfection as well as filtration, then that needs a contact time to work and drinking via a straw is not going to give adequate contact time.

Just my (inexperienced) thoughts.

I spotted the istraw in my local Blacks shop recently, thought it might be handy until I read the small print.....it doesn't eliminate viruses.

Suffice to say, it went back onto the shelf !

a couple of drops of iodine, leave for 30 minutes, and then suck it up. That what they say anyway

Could be useful for a ridge walk like the Cuiilin, sup a puddle.

It dont do virus's. 74.5 degrees does. The water will require chemical or heat attack after going through the straw. An interesting concept if you have sucked the water into your mouth!!!!!! I know spit it out and then boil it????????:yikes:

I like the look of that system and it sounds pretty comprehensive so far as the purification goes. I like ythe idea of the impregnated bottle as well.

I'll vouch for the purehydration bottle filters, although if you possably can filter and boil, 99.99% is by definition not 100%.

I've also got a straw style filter for the first aid kit, a pretty major bugbear for me is the massive amount of suction pressure you need to filter the water. Drinking a litre of water over the course of a day (not enough for good hydration but better than none) gave three people blisters due to the amount of suction needed.

The style is not really ideal for everyday use but useful at a pinch.
