Backpacking is a great adventure that is enjoyed by many outdoor enthusiasts. The experience can be enhanced with proper planning and preparation. One of the essential items you should pack is a water filter. A backpacking water filter can help guard against viruses, bacteria, and protozoa, ensuring that you drink clean water and stay safe. In this blog post, we will discuss the need to pack a backpacking water filter, the types of backpacking filters available, and how to choose the best one for you.

Why do you need a Backpacking Water Filter?

Water is an essential commodity when backpacking. It is also scarce, and the quality is questionable in many areas. You may encounter water sources that are contaminated with viruses, bacteria, and protozoa, which can cause serious health problems. A backpacking water filter will help you purify water from streams, lakes, and other sources, ensuring that you always have clean drinking water. Additionally, carrying purified water reduces the weight of your backpack, which is a considerable advantage when backpacking.

Understanding the Risks

Before we dive into the top filters, it's important to understand the risks of untreated water in the backcountry. Drinking untreated water can expose you to harmful organisms like Giardia, Cryptosporidium, and E. coli, among others. These can lead to severe gastrointestinal issues, which can be dangerous if you're miles away from medical help.

Types of Backpacking Water Filters

Water filters and water purifiers use different technologies to eliminate or reduce
water-borne pathogens. The LifeStraw Flex, and Gravity filter, for instance, filters down to 0.2 microns, protecting against bacteria, protozoa, and microplastics. However, it's worth noting that this filter doesn't guard against viruses.

UV purifiers, on the other hand, kill bacteria, protozoa, and viruses, allowing you to drink clean, cold water right away. These devices require minimal effort and work quickly, making them an excellent choice for backpackers.

Filtration Pore Size

The filtration pore size is critical in determining the effectiveness of backpacking water filters. Most backpacking water filters have a pore size of 0.2 to 0.3 microns, which is small enough to catch most bacteria and protozoa. However, viruses can be as small as 0.02 microns, making them difficult to filter out. Some tested backpacking water filters use a multi-stage filtration process to remove both bacteria and viruses from the water.

Choosing a Backpacking Water Filter

When choosing a water filter or purifier for backpacking, there are several factors to consider. First, think about the types of pathogens you need protection against. If you're hiking in regions where waterborne viruses are common, opt for a purifier that combats all microbes, including viruses.

Next, consider the size and weight of the filter. Lightweight filters are more suitable for backpacking as they won't weigh down your pack. Also, look at the speed at which the filter processes water. When you're out on the trail, you don't want to wait forever for your water to be safe to drink.

How to Choose the Best Backpacking Water Filter

When choosing a backpacking water filter, you should consider several factors such as the type of backpacking you plan to do, the number of people in your group, and the weight of the filter. You should also consider the filter capacity, filtration rate, and the type of contaminants the filter removes. Always choose a filter that removes viruses, bacteria, and protozoa, as these are the most common water contaminants. Additionally, consider purchasing a water filter that comes with a warranty, as this guarantees its quality and durability.

Portable Water Filter vs. Water Purification Tablets

Portable water filters are not your only option for clean water in the wilderness. Water purification tablets are an affordable and lightweight alternative to backpacking water filters. Purification tablets use chemical treatments such as iodine or chlorine dioxide to disinfect water and kill bacteria and viruses. However, they may not be as effective as water filters in removing sediment and debris. They can also leave an unpleasant chemical taste in the water, and some people may have an allergic reaction to the chemicals.


When backpacking water filters and purifiers are vital pieces of equipment for any adventurer. They ensure that you have access to clean, safe drinking water, no matter where your journey takes you. Whether you opt for a simple filter or a comprehensive purifier, make sure it's reliable, efficient, and suited to your specific needs.

Remember, not all filters are created equal. Some guard against bacteria and protozoa, while others also protect against viruses. By understanding the differences and considering your specific needs, you can choose the best backpacking water filter for your next adventure.

Not Ideal for Large Water Quantities: The LifeStraw is designed for personal use and isn't ideal for filtering large quantities of water. This might pose a challenge for groups or for those needing to filter water for cooking.

Dependent on Water Source Availability: The LifeStraw requires a water source from which to drink. In areas where water sources are scarce or non-existent, this could limit its usefulness.

Our Thoughts - The LifeStraw Personal Water Filter offers a range of benefits for outdoor enthusiasts and those preparing for emergencies. However, it's important to consider its limitations when deciding if this is the right tool for your needs.

How to make water drinkable in the wilderness?

Ensuring you have access to safe, clean water is crucial for survival. Here are some effective methods to purify water in the wild.

Boiling is one of the most effective and time-tested methods to purify water. According to experts from Uncharted Supply Co., clear water should be brought to a rolling boil and maintained for at least two minutes to eliminate harmful bacteria, viruses, and parasites. This method is particularly efficient when you have access to a heat source like a campfire or stove.

Water filters offer another practical solution, especially when boiling isn't an option. Most filters work by passing the water through a screen with tiny holes, which helps remove impurities. The National Park Service recommends using filters as a first step, followed by boiling or disinfection to ensure the water is safe for drinking.

In arid regions, digging for water can yield drinkable water. As suggested by Quora users, looking for damp soil or vegetation can indicate the presence of underground water. Digging a hole allows you to collect this water, which has naturally been filtered through the soil.

Distillation is another effective method of water purification, particularly when dealing with salty or contaminated water. Outdoor Life recommends heating water into steam and then capturing the steam to create relatively clean water.

Finally, UV lights and purification tablets provide modern solutions to water purification. These methods work by killing bacteria in the water supply, making it safe to drink.

Regardless of the method you choose, remember that the goal is to remove harmful contaminants and make the water safe for consumption. Always ensure you follow the recommended guidelines for each method to effectively purify your water in the wilderness.

How did our primitive forefathers purify water?

Despite the absence of modern filtration systems, our ancestors developed a variety of methods to ensure their water was safe for consumption.

One of the earliest and most common methods our ancestors used was the extraction of well water. Wells provided a natural filtration system, as the water was stored in complete darkness and within rock formations, which helped keep it clean and safe for drinking.

Ancient civilizations like the Minoans and Greeks were known for their rainwater catchment systems and cisterns. These structures collected and stored rainwater, providing a sustainable source of potable water. The collected water was often covered, further ensuring its purity.

Earthen vessels were another tool employed by early humans to store and purify water. The clay makeup of these vessels not only kept the water cool but also enriched it with minerals and increased its alkalinity, improving its bioavailability.

Sand and soil filtration was another technique utilized by our ancestors. They built sand filtration columns to filter out impurities from the water, a method that mirrors some modern filtration systems.

Boiling water was, and still is, a popular method of purification. This age-old trick effectively kills bacteria and other harmful organisms, making the water safe to drink.

Interestingly, silver also played a role in water purification throughout history. Its antimicrobial properties made it an effective agent for killing microbial organisms in water.

Lastly, in societies where boiling water wasn't always feasible, converting water into alcohol was another method used to make water safer. This process helped to kill off harmful bacteria and parasites, providing a safer (and more flavorful) alternative to contaminated water.

How did the Vikings get fresh water?

The Vikings, known for their seafaring prowess and long voyages, faced the challenge of securing fresh water while at sea. So, how did the Vikings get fresh water? Their strategies were ingenious and multifaceted, demonstrating their adept survival skills.

Primarily, the Vikings' voyages often took place in shallow water and close to the coast. This proximity to land granted them frequent opportunities to go ashore and replenish their freshwater supplies.

Additionally, larger Viking ships carried barrels of fresh water on board. These barrels were part of the ships' stores and could be refilled during the voyage, particularly during rainfall. The use of barrels for storing liquids is well-documented from the Viking period.

Interestingly, the Vikings also had a keen understanding of their environment and used this to their advantage. For instance, they could determine if fresh water was flowing from the land into the sea using only their taste buds.

Viking ships themselves were designed to be watertight, with spaces between planks filled with wool, moss, or animal hair, mixed with tar or tallow. While not directly related to obtaining fresh water, this construction ensured that seawater did not contaminate their freshwater supplies.

Lastly, fermented beverages like beer, mead, and ale played a crucial role in Viking voyages. These drinks had a longer shelf life than freshwater, which allowed the Vikings to embark on longer expeditions without having to stop as frequently for fresh water.

Can one drink water straight from a spring?

While the image of drinking fresh, clear water directly from a spring may seem idyllic and pure, it's crucial to understand the potential risks before doing so.

Typically, water moving through layers of rock and sand in a spring undergoes a natural filtration process. This can make spring water safer to drink than water from other natural sources. However, it's important to note that as soon as the water surfaces, it is exposed to various pollutants and contaminants.

Health authorities, such as the New York State Health Department, caution against drinking water from roadside springs and other uncontrolled, untreated water sources. Similarly, research from the Penn State Extension suggests exercising caution when consuming water from roadside springs.

While spring water may taste great, that doesn't necessarily mean it's safe. Untreated springs are generally considered unsuitable as a drinking water source. If you're considering drinking spring water, it's recommended to boil it first to kill any potentially harmful microorganisms.

Not all spring water is equal, and the safety of consuming such water can widely vary. Factors such as the geographical location of the spring, nearby human activity, and local wildlife can all impact the quality of the water.

As a rule of thumb, if you're in doubt about the safety of spring water, it's best to treat it before consumption. This could involve boiling, using water purification tablets, or employing a portable water filter.

Is filtering water enough for backpacking?

Backpacking and camping often take us to remote locations where access to clean water can be a challenge. A common question that arises among outdoor enthusiasts is, "Is filtering water enough for backpacking?" While water filters and purifiers are an essential part of any backpacker's gear, it's crucial to understand their capabilities and limitations.

The Role of Water Filters in Backpacking
Water filters play a pivotal role in outdoor adventures. They effectively remove particulates, bacteria, and protozoans (like Giardia and Cryptosporidium) from water sources. Some of the best backpacking water filters of 2023 include the Sawyer Squeeze, Katadyn BeFree, and Platypus GravityWorks. These filters are user-friendly, efficient, and compact, making them suitable for backpacking trips.

Limitations of Water Filters
While water filters are effective against many waterborne threats, they have certain limitations. Viruses, for instance, are smaller than protozoa and bacteria, making them difficult to filter out. This could pose a risk in areas where water sources may be contaminated with viruses like Hepatitis A, rotavirus, or norovirus.

Additionally, water filters do not remove chemicals or heavy metals from water. If your water source is near agricultural or industrial areas, it might be contaminated with these substances.

Complementing Filtration with Other Treatment Methods
To ensure safe drinking water while backpacking, it's often recommended to complement filtration with other treatment methods. For instance, using chlorine dioxide drops or pills can help kill viruses that filters might miss.

UV purification is another method mentioned frequently in the backpacking community. However, commercially sold lights may not be strong enough to make ultraviolet light fully purify water.
