A healthy adult can survive for weeks without food, but only about 2 to 3 days without water. Much of our time and money devoted to prepping revolves around food: storing, growing, bartering, and protecting it. We don’t give as much thought to prepping for water. Perhaps we take clean potable (“drinkable”) water for granted. You turn on the faucet, and a never-ending flow of clean safe water pours out. Yet we know that many different types of disasters can disrupt the water supply.
A water purification device is one of the top essential products for prepping and survival. The best devices remove protozoa, bacteria, and viruses. The mediocre ones fail to remove viruses. The reason is that viruses are the smallest pathogens, and water filters must have very fine pores to screen them out. Until recently, very few devices removed viruses and they were rather expensive. But that is changing.
Previously, I reviewed LifeStraw Family, a water purification device I purchased, own, and recommend. It removes protozoa, bacteria, and viruses. Now there is a new version of LifeStraw called “Community”. They say it’s great for “schools, health facilities, workplaces and community settings.” I say it’s perfect for prepping.
- Can purify between 70,000 -100,000 liters of water
- 25 liter dirty water tank and 25 liter safe storage tank: total capacity of 50 liters
- Filtration rate: 12 liters/hour
- Purified water can be collected from any of the four taps.
- The blue tap is turned to release purified water.
- The red backwashing handle allows semi-automatic backwashing; when it is pulled down and released, pathogens and dust particles on the dirty side of the membrane are lifted by backpressure and then flushed out into the red backwash container.
What you need in addition to the LifeStraw Community (or LifeStraw Family) device is a source of water. The device cannot remove salt from salt water, nor chemicals from pool water or other contaminated sources. It removes particulate matter (muddy water, cloudy water), and harmful pathogens, but not heavy metals, petroleum products, or other chemicals. So you need a reasonable starting point for the water purification. Pond water, rain water, and unsafe tap water should all work.
Is this device overkill for a prepping family? I don’t think so. You could always purify water for neighbors, friends, and family (for a fee, perhaps). The device is not much more expensive than other high-end purification devices, which offer much lower volume of purification. And the high filtration rate means you don’t have to wait long to get the water you need.
The European company that makes all the LifeStraw devices is Vestergaard. You can get their water purification devices at EarthEasy. See the banner ad in the top right column of this page. LifeStraw Community and LifeStraw Family remove protozoa, bacteria, and even viruses. Some of the other, less expensive, LifeStraw products only remove protozoa and bacteria, not viruses.
