bacteria, viruses and protozoa

TRAVELERS who don’t trust the water from a mountain stream or a hotel-room faucet have often used chemicals or filters to purify it. Now they have a high-tech option as well: swirl the water with a portable, lightweight wand that beams rays of ultraviolet light.

The SteriPen JourneyLCD is built to be portable for travelers who fear the tap and for campers who want to do more than filter stream water.

The wand can clean up a quart of water that is clear — but could harbor stomach-wrecking microorganisms — in 90 seconds. The high-frequency light damages the DNA of bacteria, viruses and protozoa in the water like giardia and cryptosporidium so they can’t reproduce and create havoc.
