Why do we need the best survival water filters? Water is essential for our life. Sure, you can get safe drinking water from the tap or buy bottled water. And during camping or any other outdoor activities, you’re still able to boil some water. However, there may be a situation when you run out of water or can’t guarantee the quality of the water even after you boil it. Furthermore, it can be hard to get clean and safe drinking water during natural disasters. Unsafe or contaminated drinking water can have bacteria like E.coli and other pathogens. And it can cause health effects, such as vomiting, headaches, nausea, diarrhea, and sometimes even death.
Thus, having reliable water filters for survival is your best way to prepare for the worst or unpredictable scenarios. Thanks to technology, survival drinking water filters are now better than ever. Besides, they’re portable. It’s great for campers, hikers, travelers, and outdoor enthusiasts who wish to safeguard themselves in the wild. What’s more, it’s also perfect for emergency preparedness like tornadoes, floods, hurricanes, and more.
How to Choose the Best Survival Water Filters
There are plenty of survival drinking water filters out there. So, how do you choose the best one? Here are some factors you should consider to get the best ones for you.
Water filters for survival come in several types depending on how the water is forced through a filter. It’s either sucked through your mouth using a straw or pushed the water via squeezing or pump. Some water filters are made for backpacking. They are usually easier to use and lighter in weight. Some others are built into water bottles. If this is something you prefer, take a look at our top picks for water filter bottles instead.
Some manufacturers claim that their filters last very long. Sounds good, right? But, you also need to consider whether your chosen water filter has replaceable parts. Better you buy from brands that offer filter replacements. This way, when your filter runs out of its capacity, you only need to buy the filters instead of buying the whole thing.
A simple, budget-friendly water filter can work just as well as an expensive filter. However, if the more expensive filters can filter more gallons, it can be a great long term investment.
Easy to use
During an emergency, all you need is water filters for survival that should be easy to use and be able to adapt to different conditions. You will need a water filter with a stress-free process that you can use without having to read through the step-by-step instructions. Straw-like filters may have many advantages, but they only work if you can drink them straight from the source.
How do you filter and purify water for survival?
There are several ways you can filter and purify water using water filters for survival. One of the easiest ways is using a water filtration system. It removes water contaminants like parasites, protozoa, and chemicals. You can also use tablets or drops like iodine, chlorine, or potassium in small doses. They’re efficient in removing harmful substances from your drinking water. Boling water is also one of the best water purification methods. Most microorganisms and bacteria can’t survive during the heating process.
Do any water filters remove viruses?
Most water filters are designed to remove bacteria and protozoa, not viruses. Viruses have a smaller microscopic scale than protozoa and bacteria. However, some survival drinking water filters claim that their survivor ultrafiltration devices remove viruses.
How to find water in the wild?
If the worst-case scenarios happen, any survival expert will tell you to always filter or purify water in the wild. Clear, flowing water is your best source of water in the wild. You should look for streams first or spring if possible. Rainwater is another best source of water as well as the lake, pond, and rivers.
What happens if you don’t change a water filter?
The filter in your survival drinking water filters will begin to wear out in time that makes it less effective in filtering out the various microbes, chemicals, and other contaminants that the water supply may contain. If you don’t change the filter out, the contaminants may potentially harm your health.
