How effective is LifeStraw against viruses?

LifeStraw is not effective against viruses, which is a limitation of this filter. While it effectively removes 99.9999% of bacteria and 99.9% of parasites, it does not filter out viruses due to their smaller size. For areas known for viral contamination, consider additional filtration methods, such as chemical treatments or UV purification. Many users carry LifeStraw for emergencies but are educated about its limitations. Understanding this can help you make informed choices for your water purification needs. PRO TIP: Always assess the water source and consider additional purification methods if viruses are a concern. CONSIDERATION: If your water source is potentially contaminated with viruses, look into combining LifeStraw with a UV purifier.
