What is the difference between a water filter and a water purifier?

LifeStraw offers both filters and purifiers. Microfilters (~0.2 microns) remove bacteria, parasites, microplastics, and dirt. Ultrafilters/purifiers (~0.02 microns) can additionally remove viruses. Some systems combine filtration with activated carbon and ion exchange to reduce certain chemicals and heavy metals.

How does LifeStraw test its water filtration products?

Products undergo internal quality control testing in an ISO-certified in-house water lab plus external accredited lab testing. LifeStraw emphasizes log-removal performance framing and provides evidence dossiers for transparency.
