I knew about heavy metals, parasites and chemicals in water, but now i have to worry about “gribblies” too? I didnt even know gribblies knew how to swim!!
Thanks for the reminder, time to get a Berkey!
Aha, apparently the small, individual lifestraws do not remove viruses, but the larger LifeStraw Family does.
Some may want to give their opinion. Mine is in Post #18
the combo would be bulky, require batteries and have a breakable bulb. that’s why. they’d wind up with so many customer complaints from normal use. if bulb dies or is on its way out, how’d you know if water was safe enough? diferent water has diff levels ofcstuf to kill, how do you know it’s been on long enough?
Bulb: LED.
Power: generator attached to pump handle.
Exposure time: simple statistics of microorganism survival time vs. UV exposure.
No different from problems solved by current filters & purifiers; just a matter of repackaging into a minimal unit.
Gribblies are sneaky that way.
An RO filter can.
bulkiness and weight would still be an issue. not saying it cant be done just saying if too bulky/heavy less folks would buy it.
I like it. I wrote a review here, http://thesurvivalmom.com/2012/09/20/life-straw-a-portable-affordable-water-filter/
I actually had my daughter go outside and put some backyard mud in a drinking glass. We filled it with water, and I used the Life Straw to drink. Tasted perfectly fine.
So do you risk popping a vein as you try to suck water through the straw, like trying to drink a thick milkshake through a straw?
