These seem to be getting popular. Has anybody who has purchased one ever actually used it even once??

There are lots of stories of this product saving lives in real situations. It's existed for at least a decade, so not a new product.

During 'black friday' you can often get one on Amazon for $20, but if you need more than 1 then the costco deal is great.

I use the "go" versions which have a nalgene like bottle for camping/hiking/kayaking & the family for base camp. I also have their kitchen filter. The regular one isn't really worth it when the ones with built in bottles/adapters to fit on existing bottles exist.

Can I drink from Lake Ontario and the Don River with one of these and not get violently ill? If so then it sounds good.

Relax, there are limits to what science can do.

*On a real note, you probably can.

Good find, but I’m waiting for the LifeStraw Flex to go on sale. You can use that with regular water bottles, makes more sense to me.
most things haven't worked out

Can confirm I used this product once in ~6 years. But it does support children, so bonus points for buying. I guess these would make ok stocking stuffers or something.

There are better options for water filtration such as a gravity filter or Sawyer or the other lifestraw that sits within a water bottle.

These devices will only filter out "bacteria" and "parasites", which are relatively larger in size.
Any water-borne virus will pass through (although subsequent treatment with chlorine or boiling should kill/inactivate most viruses/viri).
Any dissolved chemicals will pass through (cyanide, chromium VI, soluble radioactive isotopes, etc.), and chlorine treatment or boiling will not do anything to remove these.

In conclusion: these are good for filtering water which, aside from unsafe levels of "bacteria" and "parasites", would otherwise be safe to drink in the first place.

im still confused why you would use this. Are you thinking you might be stranded and lost at one of our national parks and dying of thirst and you might need this?

I personally use a Sawyer squeeze but yes that is a legitimate reason. Theyre great for a weekend backpacking trip so youre not carrying 10+ liters of water. Even for day hikes in hot conditions its easier to bring a smaller 1.5-2L container and refill midhike if you know you will have a reliable water source

Platypus mircofilter is King for these types of water filtration in the outback/ wild.

Their ability to connect to popular water bottles makes them the ideal choice

Does the straw have an expiry date on it. I see digg advertising this as a sponsor for the past year

Sawyer is up there too. Lifestraw literally sucks hard, too much pressure required.

All I hear is you're saying I can get high for free just by swimming in Lake Ontario

I do a lot of fishing. It really sucks when you get stranded in the middle of a lake and have to wait for a few hours for someone to tow you back to shore and all you have is the last gulp of water in a water bottle and are surrounded by undrinkable lake water in 32 degree Celsius heat. At $10 each, if it means I can stay hydrated in the boat or in the bush or anywhere that I might unexpectedly spend more time than I plan, it's a good investment.

Good thread ... but know your needs !

I use an MSR MiniWorks expensive but ... a water filter is designed to remove waterborne protozoa and bacteria, but not viruses. A water purifier is designed to remove protozoa, bacteria and viruses, offering a higher level of defense.
