A portable water purifier makes water from streams, ponds, rain barrels or doubtful taps safe to drink by removing or killing bacteria, protozoa and viruses. It lets you refill on the move during an evacuation, a long walk home or a permanent move, so you carry the tool instead of every gallon.
A portable water purifier turns found water into safe drinking water when you are away from home. Pick one light enough to ride in your bag every day.
- Virus protection: Choose a unit rated for viruses as well as bacteria and protozoa, since that rating is what makes it a purifier.
- Capacity: Check the rated lifespan in gallons and plan on about one gallon per person per day.
- Weight: Pick a squeeze, straw or pump design small enough for a side pocket so you can drink while you walk.
- Freezing: Keep it in an inner pocket in cold weather, because ice can crack the element and leave it unsafe.
- Power: Pack spare batteries or a charging option if you choose a UV pen.
- Cloudy water: Strain murky water through a bandana first to protect the element and stretch its life.
