5 Survival Portable Water Filters Worth Considering

Water is essential for our life. So, one of the things you can’t survive any disaster without is a portable water filter.

Most of us preparing for survival would take a personal water filter with us first. When the infrastructure collapses, the production of bottled water also stops. We have only natural sources of water that are heavily polluted. That is why we need a quality water filter. These water filters can effectively reduce up to 99.99 percent of harmful substances.

Personal water filter is useful for hiking, camping, and other trips, not just for emergencies (tornadoes, rain storms, earthquakes, floods, etc.)

If you are interested in buying a personal water filter, You must pay attention to several factors such as the degree of efficiency of water filtration, the capacity of the vessel, the lifetime of the entire device, the speed of water flow, the total amount of water for filtration, and the possibility of application in multiple situations.

Where To Find Water In The Wild?

Any survivalist will tell you always to filter water that flows. Firstly, you should look for streams if possible. Rainwater is another good source of water, as well as lakes, ponds, and rivers. You can check out our post on finding water in the wild for more help in that area!

What If The Portable Water Filter Breaks?
