Exstream XR Water Purifier
Just dip and sip - the easiest, most convenient way to treat your water. Excellent for traveling, paddling, biking, day hikes, fishing, etc. Carry loop provides easy attachment to packs, kayaks, etc. No hassle with hoses, pumping, or separate containers. Just scoop or fill the bottle with water and squeeze. The ViruStat purification cartridge purifies water on demand (no waiting). Highest safety level - removes bacteria, protozoa (Giardia, cryptosporidium) plus kills over 99.99% of waterborne viruses, as determined under the U.S. EPA. Treats 26 gallons (100 liters) per replacement cartridge (4-6 weeks when used regularly). The only EPA registered purifier bottle. 34 oz. bottle (similar to Nalgene 32 oz. size) (not pictured). Wt. 7 oz.

Untitled ReviewWith the filter, the water comes out somewhat slowly, but I expected that. I take one with me on overnight trips plus regular water bottles. I use the Exstream to filter water into the other bottles. It takes about 5 minutes to filter 1 liter of water. Yes, it's slow, but not ridiculously so (what else is there to do in camp?) and saves a bunch of weight. I do not filter water I intend to boil.
I found that without the filter, the bottle can take boiling water just fine (did that in Tibet, so I could use it in my bag as a heater). It never leaked.
I highly recommend them. I believe these are one of the only systems with EPA approval.
