How the LifeStraw Personal Water Filter works:
LifeStraw’s membrane microfilters are made of hollow fiber membranes. These have microscopic pores of 0.2 microns size. Dirty water enters on one sideand bacteria, parasites, and microplastics are trapped because they are larger than the pores. Only clean water passes through.
- Ultralight (2 oz.)
- Filters as you drink – no batteries, no pumping
- Rigourously tested
- No expiration date
- Your purchase helps provide clean drinking water for children in need
The hollow fiber membrane technology inside of the LifeStraw keeps you safe during outdoor adventures. All of our filters are rigourously tested.
The LifeStraw Personal Water Filter will transform 4,000 liters (1000 gallons) of contaminated water into clean and safe drinking water. That is more water than the average person drinks in a year.
During any natural disaster or emergency event, locating safe drinking water is vital. the LifeStraw never expires, and its small footprint makes it a perfect fit for emergency kits, survival kits, and hiking and camping backpacks.
