Backcountry Water Filter Essentials
Here are several options we like for filtering water while backpacking:
Pump filters: use a hand pump to force water through a filter into a container. They effectively remove a wide range of contaminants and are a good option for group trips. A favorite of ours, they just work.
Gravity filters: use gravity to pull water through a filter and into a container. They're convenient for larger groups and base camps. You can easily fill a 7 gallon jug with these within about 30 minutes.
Squeeze filters: are compact and lightweight, and use a squeeze bag to force water through a filter. They are a good option for solo or lightweight trips.
Straw filters: are personal, handheld filters that allow you to drink directly from a water source. They are the lightest and most compact option, but may not be suitable for groups or for filtering large quantities of water.
Chemical treatments: such as iodine or chlorine dioxide, are another option for filtering water. They're lightweight and compact, but they can take longer to purify water and may affect the taste. We recommend these as a backup option for water treatment when traveling in foreign countries.
Do I Need a Water Filter for Backpacking?
In short, yes. Even in the most remote and pristine locations. Never assume that water sources are free of contaminants. Streams and rivers can contain pathogens like Giardia, E. coli, and Cryptosporidium – all of which can cause serious illness. Whether you're on a multi-day trek or a day hike, a good water filter ensures you’re hydrating safely.
Purifying Water While Backpacking: Filtering vs. Boiling
Filtering is by far the most convenient and reliable. Boiling water is effective but time-consuming and impractical for larger quantities. Chemical treatments, such as iodine or chlorine, can alter the taste and take time to work. In contrast, water filters offer immediate results, removing particles and pathogens without compromising taste.
Best Water Filter for Backcountry Trails
A multi-stage filtration system is ideal as it ensures that whatever is in the water (sediment, microorganisms, or chemicals) is filtered out effectively. A filter with a high flow rate will also keep you from losing time pumping water when you need to get back on the trail.
Healthiest Way to Filter Water
When it comes to your health, you want a water filter that can eliminate bacteria, viruses, chemicals, and heavy metals. For this, reverse osmosis systems and multi-stage filters are the most thorough options. While these are more expensive, they offer the most comprehensive filtration, ensuring your water is as clean and healthy as possible.
What Water Filter Removes the Most Contaminants?
Reverse osmosis filters remove the widest range of contaminants, including bacteria, viruses, chemicals, heavy metals, and even microplastics. They tend to be larger and require more frequent maintenance, so for backpacking, a multi-stage filtration system that incorporates both mechanical and chemical filters is often the most practical choice.
Disadvantages of Filtered Water
While filtered water is generally safer, it’s not without its downsides. Some water filters can strip water of essential minerals, which may affect taste and hydration levels. High-end filters like reverse osmosis systems can be expensive and require regular maintenance to function properly, and portability can be an issue with bulkier filters.
Best Water Filter for Hiking
When you’re hiking, convenience is key. Choose a water filter that is lightweight, compact, and easy to use. Squeeze filters or straw-style filters are excellent options for hiking since they offer quick, on-the-go filtration. If you’re carrying a heavier load or hiking long distances, consider a gravity-fed filter, which allows you to filter larger quantities of water without manual pumping.
Safety of Backpacking Water Filters
Follow the manufacturer’s instructions, clean your filter after each use, and replace cartridges as recommended. A well-maintained filter is your best defense against contaminants.
Do Hiking Water Filters Work?
Yes, hiking water filters absolutely work—provided you choose a filter appropriate for the water conditions you’ll encounter. Most filters can effectively remove bacteria, protozoa, and sediments. If you’re hiking in areas where viruses are a concern (such as regions with high human or animal activity), opt for a filter with a purifier attachment or a multi-stage system that also addresses viruses.
Water filters are essential for backpacking or hiking adventures, whether you’re navigating a challenging trail or simply staying hydrated on a day hike. Choose wisely and enjoy your next adventure with peace of mind!
