You might know what I'm talking about. If someone is curious I can take a pic of some of mine

Filtration (or bleach) also won't remove toxins from water either.
Guess you E&E home or drive through
Yeah I use the sawyer too. It connects to like 90% of disposable bottles from quick trip. Coke, Pepsi, a lot of water bottles, etc. I love it.
While technically correct this is still wrong. Ultrafiltration IS purification. Conventional filtration only works using chemicals(aluminum sulfate) to induce "flocculation" which creates particles clumps that can then be bound together using a coagulating agent such as a polymer. That's the only way to make the solids into large enough particles for a conventional filter to trap them. An "ultra filtration device traps particles so small that coagulating agents aren't needed. And when they trap small enough they actually replace the deactivation process of chlorine or ultra violet light and act as complete purification via ultrafiltration. Reverse osmosis is filtration that need NO other processes to purify. It is called nano filtration and allows nothing larger than the size of a single molecule of H2O to pass through. Now is that filtration or purification? One and the same.
" When you suck on your LifeStraw, water is forced through hollow fibers, which contain pores less than 0.2 microns across -- thus, a microfiltration device.
Vestergaard Frandsen says a personal LifeStraw unit should be able to purify about 1,000 liters (264 gallons) of water -- 2.7 liters (0.7 gallons) a day -- meaning that it will last a year before it needs to be replaced. There are no replacement parts; users must get a new unit each year."
"
LifeStraw Family is a larger unit that can purify enough water for several people at once. This higher-capacity product can handle a family of five for three years, or roughly 18,000 liters (4,755 gallons), according to the company. The product consists of a blue bucket with a prefilter insert, a long plastic tube and a filter cartridge with a tap attached to draw out the water. No electricity or battery power is required. Gravity guides water through a series of filters. The user pours water into the prefilter and bucket at the top of the unit. The water then moves down the tube and runs through the same type of hollow fiber technology that the personal LifeStraw uses, but these pores are actually 0.02 microns across, which makes it an ultrafiltration device. (It also means the family unit can filter out viruses, while the personal one can't.) The user can then pour the newly purified water from the tap. The person can clean the filter by closing the tap and pressing a red squeeze bulb to release the collected residue and can use a rag to wipe the prefilter bucket. LifeStraw Family can filter about 9-12 liters (2.4 to 3.2 gallons) of water per hour"

Interesting article. I like all the info.
All that being said, the sawyer has a 100,000 gallon guarantee and will likely last a lifetime.
So if each person in your group has one in their bag, or you give one to a friend/loved one, it could last the rest of their life.
Of course I recommend more than one line of filtration. Just making a point.
It would suck to be make it one year past an EMP only to have your water filtration die.
Wasn't trying to be rude btw. I think life straws were great in their day.
I just think there is a superior product now. That's all.

Ya I would have to agree the sawyer is pretty awesome
While I was quoting that article earlier, I looked at the water treatmentdevice I had bought a couple of months ago (I think at Walmart ) and lo and behold it's a Sawyer. Lol. I remember thinking it sounded almost too good to be true and grabbing it. But I set it aside and forgot it. Then someone on here linked a deal on the Lifestraw Family unit and I got one of those too. At .02 micron, it's almost Reverse Osmosis. And the capacity is awesome as well.
