Why Do You Need The Best Backpacking Water Filters?

It is essential for a backpacker or outdoor goer to remain hydrated all the time. But realistically speaking, that's not something that you can ascertain, especially if you only carry a bottle of water or two. If you are into day hikes, this matter shouldn't be a problem. But for extended trips, you may need to refill your water bottles from time to time. 

Of course, you can't expect that you'll find a faucet during your trip--unless you are going to an established campsite with complete amenities. But most of the time, you'll only rely on ponds, lakes, and rivers. However, before you take a sip, you have to think first if the water source is clean or not. 

If you are uncertain, then there's a need for you to invest in a water filter. This is a device that lets you cleanse any water source from contaminants and waterborne illnesses. 

When choosing one, you should mind the following considerations:

Water Filter And Water Purifier: What's Their Difference?

The terms "purifier" and "filter" are interchangeable. But they have some key differences. 

First, a water filter is designed to remove bacteria and protozoa in the water. A purifier can do the same, but it removes viruses, too. Another difference is that water filters have cartridges that physically strip bacteria and protozoa. Purifiers eliminate viruses and harmful organisms through microscopic fibers and chemical agents. 

Water purifiers cannot filter sediments, though, and that's their downside. The possible exception here is the MSR Guardian Purifier since the latter is designed to be a purifier and filter at the same time. Within the United States, you are safe with just a water filter. But for international backpacking tours, you need to get a purifier. 

Types Of Water Filter / Purifier

You have different options for water filters and purifiers. Here are some of them. 

  • Gravity filters - They are touted to be the most convenient option for filtering water in backcountry applications. With a gravity filter, you fill a reservoir with the water from the water source and hang it somewhere (such as a tree branch). After that, gravity does its thing by pulling the dirty water through a filter before proceeding to the receptacle. The downsides of gravity filters are their size and weight. They are not that easy to pack, either.
  • Pump filters - A pump filter, such as the Katadyn Hiker, will need you to pump water from rivers, lakes, or other water sources. The pumped water will then pass through the filter of the device before it is sent into a reservoir or bottle. A pump filter lets you draw drinking water from shallow sources. It also filters water, even in small quantities. On the flip side, you may need to lend some extra time and effort to use these pump filters. 
  • Bottle filters - A bottle purifier or filter is directly attached to the mouth of your container or bottle. It filters your water while you drink it. Such a mechanism enables bottle filters to be a convenient choice for many backpackers. You simply need to fill your bottle with any water that you come across and drink it once you feel parched. Of course, there's a downside to these bottle filters, too. One, they are slow in cleaning water. Second, they only process small volumes of water.
  • Straw filters - If you don't want to carry bulky and heavy water filters, then you should get straw filters. Just as their name suggests, these straw filters are designed to be like straws. Specifically, they have a tubed body that contains an internal filter. You use them the same way you use a straw. This means that if you have a straw filter, drinking directly from a water source is entirely possible. Of course, the downsides are relatively evident. These straws don't let you store water, which is disadvantageous if you are traveling in areas where water sources are scarce. Moreover, there's a certain degree of inconvenience whenever you use them; after all, you need to lie on the ground to take a sip. 
  • UV filter - Another means of purifying water is through UV filters. They utilize ultraviolet rays to cleanse the water from pollutants. But because a UV filter doesn't have a physical filter, there's a need for you to pre-filter the water first. Moreover, this filter can only purify up to one liter of water at a time. 
  • Chemical purifier - A chemical purifier is a traditional way of eliminating pollutants in the water. They usually come in drops or tablets; you add these things to your water container and let them sit for a couple of minutes. They are generally inexpensive and lightweight. But similar to UV filters, they don't have physical filters. Hence, there's still a need for you to pre-filter them.

In Summary

The best backpacking water filters are essential so that you can stay hydrated on your trip. With these water filters, you will be able to sustain the rigidness of your journey. You'll not succumb to thirst and dehydration, which have catastrophic consequences for your body.
