    What is a Portable Water Filter and Why Do I Need One?

    Portable water filters help you be able to have something clean to drink, no matter where you happen to be. This is especially important for those who do backcountry hiking or frequently travel outside of North America or Europe. Water quality varies widely around the world, so the best strategy for hikers or travelers to use is to filter their water before they drink it.

    A portable water filter can remove chemical compounds from the water, such as chlorine, to improve its smell and flavor. Some filters are able to remove bacteria, amoebae, and protozoa that may be present in the water as well. UV sanitation, when included with a portable water filter, can even remove a virus that might be lurking in the water supply.

    Even though a water source may be clean, all it takes is one infected animal (or human) to leave waste materials in the water to contaminate it. The best portable water filters will remove the contaminants and then store up to 8L of water for future consumption. That way you only need to work on the filtration process a few times per week instead of a few times per day.

    How to Find the Best Portable Water Filter for Me

    There are four basic types of portable water filters that can be considered in this category.

    Micro-filters. These are hand-held water filters that are good for hikers, campers, and general travel. They are stronger than a standard household-style water filter, like you’d find in a water bottle, but will only remove basic contaminants from the water supply. Some are rated to remove bacteria and protozoa.
    Gravity Filters. This type of filter does a good job against most types of water contaminants, though micro-viruses may still be able to enter the water supply. If cysts, bacteria, and protozoa are suspected to be in the water, this device will help you make sure you have a clean drink of water to enjoy.
    Pump Filters. These work in the same way as a gravity filter but use a pump to move the water through the filter instead of gravity. This is your best option if you aren’t sure that you’ll have enough space to hang a filter somewhere so that gravity can move the water through the filter.
    Purifiers. This is the type of portable water filter you’ll need when there is a suspected virus living in the water. It is recommended for all travelers outside of North America and Europe when a natural water source must be tapped. It may also be required in communities when a “Do Not Drink” order has been issued for the local water supply.

    Even with the best portable water filter helping you get the clean drink you need, there may still be a requirement to disinfect the water. For this reason, you may wish to stock a supply of chlorine dioxide tablets. These tablets are rated to be effective against viruses, micro-organisms, and even Cryptosporidium.

    We recommend this box of 30 water purification tablets from Potable Aqua to purify your water because it has a minimal aftertaste and only requires 4 hours of treatment time for the most contaminated water supplies.

    What Else Can I Do to Purify My Water?

    If you’re not sure about which portable water filter is right for you, then there is always a fail-safe option available to you. Boiling your water is a foolproof way of making sure it does not contain any contaminants. The heat will effectively disinfect the water. It is 100% effective against all waterborne pathogens.

    It is often recommended to boil your water for at least 60 seconds to make sure the heat has disinfected it. This is because the Hepatitis A virus is believed to be able to survive for up to 60 seconds in the increased heat. If you are at a higher elevation (5,000 feet or higher), then the recommendation rises to a 3-minute boil.

    This option will only work if you have fuel to heat the water and a container which can resist the heat.

    What Are the Prices of the Best Portable Water Filters?

    Entry-level water filters in this category can often be found for under $30. At this price, you’ll receive disinfectant removal and light contaminant removal.

    If you need an all-purpose water filtering and treatment system, then you’ll find prices may rise up to $120 or more for some products. At this price, you will find gravity or pump filters that can store water for your traveling needs. Look through the best portable water filter reviews for a product that is easy to assemble with an outlet hose that is compatible with multiple sources.

    A complete portable purification system which is rated to remove viruses may cost $350 or more. The price for a purifier depends on its size, the amount of water it can store, and how quickly the purification process is completed.
