How Does It Work?
How Does It Work?
Puresip Straw uses an advanced hollow fibre membrane technology.
The membrane has microscopic pores that trap contaminants larger than 0,2 microns.
Water is able to pass through but dirt, bacteria and parasites are bigger than the pores and get filtered out.
It's a highly efficient method of filtration and does not require chemicals, batteries or moving parts.

What Customers Are Saying...

★★★★★
"A must for outdoor excursions"
I frequently hike and camp in the backcountry all over the United States. Carrying the amount of water that I need to survive during these trips is just not feasible due to the weight. I recently took a filter straw out for a test on a backcountry hike in the Rocky Mountains. Every stream, lake, or other water source that I came across I stopped for a drink. I was drinking fresh snow melt and also from lakes that are home to beavers and other wildlife. There was no added taste to the water and I didn't get sick during or after the trip.

"Great for camping"
I purchased this to take on all of my camping trips. I am often out for days at a time hiking through the mountains and I've used this a number of times now in various streams or collected rain water. It filters great, the water has always tasted fine and I've never gotten sick!

"Son approved"
Mud hole tested. Son approved. I keep a few of these in the trunk of my car in case we ever get into an emergency and need clean drinking water.
