Emergency Preparedness
Stored water runs out. A good filter lets you refill from a stream, pond, pool or rain barrel. Outdoor Gear Lab's best overall personal filter, the LifeStraw Peak Squeeze, is fast and durable. The Platypus GravityWorks, its best group filter, hangs from a tree or doorframe and filters 4 liters with no pumping, which makes it the easiest way to treat water for a family. The Sawyer Squeeze is the best value and lasts for years if you backflush it. These filters remove bacteria, protozoa and sediment but not viruses or chemicals, so add purification tablets or boil the water if it might be contaminated by sewage. Never let a hollow-fiber filter freeze once it is wet; a frozen filter can crack without any visible sign.
Why it's hereOutdoor Gear Lab's Best Overall personal filter: fast (~2 L/min), durable, removes bacteria and protozoa.
