Portable Personal Water Filter Straw Purifier | Filtration for Survival Emergency Travel Camping Hiking Backpacking and Home | Purification w/Patented Technology fits in Bottles|Storage Tube Included

As stated in the headline I'm sure this is extremely handy for emergencies hence giving it 4 stars, however I wouldn't personally take this travelling as an everyday use type straw if you're trying to maybe not buy water in plastic bottles etc. Reason being it's like trying to suck a marble through a straw (Maybe exaggerating there), the flow rate is ridiculously slow, especially if you're trying to quench a heavy thirst.I'd definitely keep it in the emergency supply kit though for extreme situations.

I have not tested this out in the field yet. However, from the first looks, the purifier looks good. It's compact thus is easy to pack. It is also really light. I have tried to suck some air through it, just to get some feel and it seemed rather hard to do it. Not sure if it would be the same feeling with the water, but I hope that it gets easier since this could be a bit uncomfortable.

Instructions said to keep the straw moist, which led to it going moldy after about a month. No customer service.

Fantastic product lightweight strong the water has a little bit of a strange taste but nothing bad I found it very helpful

I always use this to drink coke it removes all the poison and just leaves the water

It's half the weight of "the blue filter straw" and I've only had it out once when fishing a local river but it served the purpose. Will need to put it to a season or more of use, but so far, so good, and it's a Canadian company. What I don't like - Glacial Stream makes claims about its effectiveness on small particles (99.99%), but I don't see any evidence that they've done any actual testing, only that these filters should perform that well. Without the evidence I guess I'm a guinea pig, so 4 stars until then.

The size was good but still too large be to replace straws as it won't fit into holes made for straws. The product only allows a small amount of water through so a lot of effort is needed to drink a decent amount of water.... Strains your ingesting muscles. Lastly the taste of the water taste the same as unfiltered hence I question if it works as advertised. I will prefer if the filter's effectiveness was confirmed by a reputable 3rd party.

I used this straw out of my tap water and compared it to my filtered water. It has a slightly different taste compared to my inline filter, but it doesn't have the chlorine taste that the unfiltered tap water has.The instructions say to allow the water to sit 1 to 2 seconds in the straw and then to draw it up slowly. I found the pressure to sip it to not be too hard - definitely something a child could do.I bought this for travel and the carry case that it came with will work well for my carry on. The only thing I wish is that the sipping cap was a different color so that it looks more like a regular straw. It's a small complaint really - but would be nice to have some choices in the color of the tip.Very happy with it overall.

I had a clean sip straw before, which my youngest ran off with, so I needed a replacement. This was what I found to be closest to the previous one I had and I was not disappointed. Easily portable, discrete, and assures that I have clean water whether it's at my local restaurant, out camping or while traveling abroad. Everyone should have one on them. Yes, it requires more work than a regular plastic straw, but then you don't want quick access to dirty water, now do you? So never mind the fuss. This baby has got you covered/

I used this product in Central America where sometimes you can taste the chlorine from the tap or restaurant water. Chlorine is used to kill many types of bacteria and germs, so perhaps that is a good sign that the water has been treated. This straw water filter definitely works well in removing the chlorine taste, providing great tasting water. It gave me more confidence that my drinking water is safe to drink. A tip is to sip slowly to ensure a good filtration. Please, refill your stainless steel bottle, and purchase less plastic bottled water!!! Safe travels!

I had this item, and i use it at my work place where has small river outside. yesterday i was lazy and not buy coffice. i use this item drinking water from river and not feel well today. i did soy test. this is the water from my m. the item does not filter junk. this is only forme in straw. bad!

Smaller than more expensive products on the market. One concern is that it says that after the first use it should be used daily,so you might want to wait until you really need to use it instead of trying it out to see how it works.

I work in Toronto, Ontario, Canada there is so much clorean in the water along with fluoride. I find it hard to drink. This filtration strew takes away the unwanted taste. I brought a spare one for my backpack that is my daily carry all.

My husband is an avid Fisher & hunter and will be gone all day when he does either of these things. He likes to keep things light & minimal while out, and this little straw will do just that. As this is a gift, I can't say if it works or not yet, but it came early & is as advettised.

My six year old grandson uses it at his other grandmother's farm where well water is used. He now no longer gets diarrhea following his visits there... highly recommend this tool

I like that the idea that it can make risky water potable. It is not like sipping from a straw where water flows naturally. It takes quite a bit of effort to sip through it.I ended up taking a risk drinking water without it. I only used it when I was very much in doubt of my drink.

Bought as a gift for my sister who can’t drink tap water due to chlorine. She carry’s it in her purse and uses at restaurants. Very handy. A bit more resistance than when sipping with a regular straw but not too much where it’s uncomfortable to use.

Arrived as advertised. I won’t be opening it as it is for an emergency kit but I can say that it is not too big and not too small. Perfect for any backpack or bugout bag!

So handy that when someone broke into my car it was one of the few things they stole. Dang! Now I need another one.

I don’t like it it is too small and I don't feel it can filter properly, but I have not tried it yet so who knows .
