美国海淘    美军装备：Sawyer 便携户外饮水过滤系统约￥124

ula. The temp was below freezing, i'de say 20-30°F, or somewhere around there. I chipped through an ice shelf on the creek and dunked the bag into the ice cold water. Filling it was easy with the current but I can see some wishing it came with a bigger bag because it doesn't look like much when the bag is filled. I use a 32oz Platypus bag I have, and carry the included 16oz bag as a backup! Anyway, I screwed the filter onto the bag, tipped it upside down and water came out with a very effortless squeeze. After I got done laughing about how simple this was, I gave my boy Yoshi a drink as well (my English Bulldog). He also took to it well, as he's a big fan of drinking from water bottles anyway. So yeah, this is a dog friendly design!Also out of curiosity I affixed the straw directly to the filter and drank directly from the creek and it was quite easy to do. The amount of suction required was similar to drinking a milkshake, and the flow rate was surprisingly great. At that point one can either shake the filter free of the water still inside the filter, and/or blow through it providing the same effect. (I should note that if using this in freezing temperatures, to prevent the filter from freezing after use, you will want to keep it on or near your body's core).When I got home I did the back flush with the syringe twice, and the thing flushed perfectly. This thing was a piece of cake to use, and was exactly what I was looking for to carry in my Heli Pack. I would recommend this filter to anyone!...and for $20, you cannot beat this. Plus you get a bag, straw, and syringe with it. Buy one now!Anyone with questions, feel free to ask/comment. Glad to help.UPDATE: After 18 months of steady use, this thing is still running strong! I have also come up with a cool addition to this water filter...I removed the sticker on the white middle section and I have replaced it with about 5 feet of standard width 1.88" DUCT TAPE! Using the filter AS the spool for the tape, allowing this filter to be a multi-purpose device. Some people will carry duct tape with them as a emergency repair kit, but we all know duct tape has a million uses, it's the cousin of paracord practically. Trust me it is cool, with the duct tape wrapped around it multiple times, the tape will eventually be flush with the filter end caps and not look sloppy at all. Plus it's a cool way to personalize your filter with a color or pattern to match your kit. If your a little picky like me, I didn't exactly want a "blue" item with my stealth gear. Anyway, this method allows you to carry a decent amount of duct tape spooled around an item you are already carrying, and not taking up ANY extra space than the filter already is using inside your kit.Why not carry some...it might come in handy sometime.

yptosporidium. We used a 2 liter bottle as a dirty water bottle and found it to be easy but slightly time consuming to squeeze fill our respective Water bottles but still way better than carrying water in. Careful freezing destroys membrane of filter not for sub freezing temperatures. Bought this brand filter over others because of its versatility to use with straw or any soda bottle and it's long life of 100,000 gallons. Check out images of the product I uploaded.EDIT After 1 year: This filter is still working great after over a dozen backpacking trips using this filter and several hikes. It is truly very nice feeling to drink the water right out of the river or lake your camping next to vs carrying in bottled water. Have used the the syringe to clean it several times and does seem to keep the flow going fast enough. I use a filtered funnel to scoop water up and into my soda bottle before filtering to keep filter as particle free as possible. I tried to use a platypus bottle bag with this filter but it does not fit quite and leaks, 2 liter bottle works best for us. Still totally satisfied wil buy another when it plugs up.

it. This filter cleans anything from questionable garden hose water to murky lake water into perfectly clear and crisp to the taste drinking water. At first, I was skeptical of course. Who would think that you can turn brown, dirty water into clean, perfectly safe water with just such a small, affordable filter? But rest assured, this filter is a powerhouse and continues to go above and beyond.One tip I have for easier and more bulk filtration is to pick up a Platypus Plastic 2L Water Bag (Link below). It's less than $10 just like the bottle you get with the filter except it allows you to filter 70oz rather than 16oz. I also got a grommet kit from a local craft store and placed 2 grommets in the corner of the bag in the seam. I then ran a 1 foot section of para-cord through the grommets which allowed me to hang the bottle on a tree branch or any other convenient location. This way you can let gravity do the work and continue on with your camp chores. I was able to filter 2 liters of water this way in around 10 minutes.One word of caution: Sawyer claims that you can filter 1,000,000 gallons of water through this filter (you're probably more likely to lose the filter before you get to that point) regardless, cleaning is a must. It will greatly extend the life and quality of your filter and water. After every filtration session I recommend flushing the filter with clean water using he provided syringe. Don't be afraid to really shoot the water in there, you're only helping your filter.All in all this filter was a GREAT buy. I don't think you can find a better filter, especially one under the $100 mark! http://www.amazon.com/Platypus-Platy-Bottle/dp/B002NZS142
