What portable filter removes viruses and parasites?

• A. Reservoirs
• B. LifeStraw
• C. Municipal Sewage Disposal
• D. Flint Water Crisis

Answer: (B)

Portable filtration relies on physically blocking pathogens as water passes through a barrier small enough to stop them. LifeStraw uses a hollow-fiber membrane with pores around 0.2 micrometers, which is effective at removing most protozoan parasites and many bacteria, making water safer to drink in the field. Its design as a compact, portable device fits the idea of removing pathogens on the go, unlike reservoirs (storage), municipal sewage disposal (infrastructure), or the Flint Water Crisis (an event). So this portable filter is the best match for removing parasites and many pathogens in a travel or outdoor setting.
