Outdoors enthusiasts know that purchasing the best camping water filter can significantly enhance your experience. For one thing, you won’t have to carry a lot of water with you when hiking– but also, a filter makes the water you might get across during your trip safe to drink. During an overlanding trip, it can act as an emergency water solution in case your water tanks run dry. Overlanders should consider camping water filters as a backup system.

Water Filters vs. Water Purifiers

Still, there’s one thing you should note beforehand, namely the distinction between water filters and water purifiers. Essentially, a water filter eliminates the impurities present in the water, such as chromium, chlorine, lead, copper, iron, and others. Concurrently, it inhibits the development of fungi and bacteria, but not of viruses. Meanwhile, a water purifier has the role of combating waterborne protozoa, bacteria, and viruses included. That’s because the viruses are too small for the filters to catch them.

How do you decide between the two? In the case in which you’re hiking in the backcountries of the U.S. or Canada, a water filter might be just enough. That’s because, in pristine environments, human traffic is reduced. Still, if you’re overlanding to less-developed countries, in locations where water treatment is poor, and the people there don’t have appropriate hygiene practices in the proximity of water supplies, getting a water purifier is a safer alternative.

That being said, we’d like to introduce you to our top recommendations of products that will maximize your safety during your overlanding or hiking trips.

In this article we will review the best portable water treatments as well as recommend you the best water purification tablets on the market.
