Sawyer Products SP140 Personal Water Bottle Filter, 34-Ounce

No one makes a water filter like Sawyer. Read the fine print when selecting a water filter bottle. Sawyer provides water solution's for 3rd world countries. Their filtering process is amazing. So perfect you can safely drink out of rivers,ponds, stream's and any other source of water. Try to avoid water sources with high levels of sediment. Every Sawyer filter comes with a backwash syringe. Pay attention to the directions and you will be drinking perfect water for a very long time. They are rated at over 100,000 gallons!! DON'T WASTE YOUR MONEY ON CHEAP FILTERS. As a proactive prepper I highly recommend this product.

I thought getting one filter for ~$35 was a pretty good deal (a single "hiker" filter typically costs $70), but instead I got a box with two bottles and filters, which turns this deal into pure *awesome*... I'm sure I only ordered one, and I don't see it saying anywhere that this is a 2-pack, but that's what I got (Aug 2012).The plastic bottle isn't impressive... Being too hard to squeeze is bad, all-around. Drinking from the bottle takes some effort, and drinking from the straw has a nasty plastic taste for quite a while. It also doesn't have a prefilter on the tubing, so you should add one yourself (or use a coffee filter or handkerchief) or only use this with crystal-clear water. The box say it comes with metal hose clamps, but instead there is a pair of nylon ... MoreI thought getting one filter for ~$35 was a pretty good deal (a single "hiker" filter typically costs $70), but instead I got a box with two bottles and filters, which turns this deal into pure *awesome*...

The box say it comes with metal hose clamps, but instead there is a pair of nylon zip ties.This isn't a purifier... it doesn't kill viruses, but there practically no purifiers on the market, anywhere, at any price. Just old-fashioned iodine or chlorine tablets, which need 4 hours, taste lousy, and no technology claims to remove 100% of contaminants. The technology really isn't there. Filters should work well, because viruses generally aren't just floating free in water, but are instead found inside larger objects, which ARE removed by a filter such as this, leaving you pretty safe. Besides, viral contamination of water is extremely rare in USA/Canada, where we don't have raw sewage dumped into our rivers and ponds. Still, YOU must decide how carefully you're going to treat water. No one is going to take responsibility if you get Hepatitis C. Even the most mundane things we do expose us to some risks of a life-threatening freak accident.

Loved the form factor. Not looking too outlandish while travelling. The filter did get rid of an inherent odour in the water in some middle-eastern cities. The flow rate does decrease quickly, but it worked well for a two week trip without needing to be cleaned. I'm sure it would have went longer if need be. The included syringe work well in restoring the flow rate when back home. Great product
