What portable device is designed to remove viruses and parasites from water?

• A. Lead Pipe Leaching
• B. LifeStraw
• C. Safe Drinking Water Act
• D. Municipal Sewage Disposal

Answer: (B)

The concept here is portable filtration that makes drinking water safe by removing pathogens. LifeStraw is a compact, hand-held filter designed for this purpose. It uses a fine membrane to physically block microbes as you sip, effectively removing parasites such as Giardia and Cryptosporidium (and many bacteria) from the water, which makes it a practical personal device for obtaining safer drinking water in outdoor or emergency situations. The other items aren’t portable water-filter devices: lead pipe leaching refers to lead contaminating water from old plumbing, the Safe Drinking Water Act is a regulation, and municipal sewage disposal concerns wastewater management infrastructure. That combination makes LifeStraw the appropriate choice for a portable device designed to strip pathogens from water.
