Writen by Ronald Brown

Fact checked by Natalie Bridges

Are you into emergency preparedness or backpacking? Do you always want clean and safe water anywhere you are? If so, you might be looking for the best water filter for travel. It is what you need for survival, hiking, and camping. This filter for a trip can get rid of the contaminants in the water. These include bacteria and other harmful substances that would otherwise endanger health.

best water filter for travel

To help you select the right one for your needs, you can refer to the following for the top suggestions from our team. Before we proceed further, let me highlight the essential factors to look for when shopping around for a water filter for travel.

  • Filtration Technology: Travel water filters vary in filtration or purification technology. Some only improve the water’s aesthetics, while others eliminate chemicals, microorganisms, and other impurities. Still, a few travel water filters use ultraviolet technology to kill microorganisms without removing chemicals. Others release chemical disinfectants into the water to make it safe to drink.
  • Filtration Capacity: Although travel water filters have a smaller capacity than other filter types, buyers must still choose one with a high capacity. For instance, a 1,000-gallon filter lasts 25x longer than a 40-gallon unit, making it a cost-effective solution for on-the-go drinks. It is worth noting that filter capacity is inversely proportional to filter replacement frequency.
  • Certification: Trustworthy travel water filter brands have a reputation to protect, prompting them to seek rigorous testing, validation, and certification for their product offerings. Meanwhile, some companies only put “NSF-certified” or the “WQA Gold Seal” on labels without providing verifiable proof. You will feel more secure and confident with a WQA, NSF, or IAPMO-certified water filter.

If you’re ready, get started in the following to help you compare and select a water filter for camping, trekking, and outdoor activities.

4. CrazyCap Insulated Bottle with NSF Certified UV Water Purifier

It is a tight race to the pinnacle of water filtration for travel purposes. As if LifeStraw and Brita are not formidable enough, CrazyCap offers its excellent portable water purifier.

I mean it when I say this product is a water bottle that purifies water in a way neither LifeStraw nor Brita can match.

Outdated Products

Seychelle Extreme Water Filter Bottle (Outdated)

You can bring it anywhere, including for hiking, camping, and backpacking. You can also bring it for domestic or international travel. You can count on it for emergency or survival, too.

It is also efficient in filtration because it utilizes Ionic Adsorption Micro Filtration. This feature is one of the best around because the function can remove many types of contaminants, including bad odor and taste. You can also count on it to remove chlorine, silt, and cloudiness. I also liked that the filter can get rid of biological contaminants, including 99.95 of viruses, bacteria, and cysts, to name some.

The 28-oz Extreme bottle is also larger size versus other types of containers on the market. With it, you can be sure of a higher capacity of clean and filtered water. It is also convenient to use because it lets you drink water from any freshwater source. This model is also designed to work for non-disinfected and contaminated water.

The filter can also eliminate inorganic contaminants, including chromium, asbestos, and aluminum, along with other inorganic pollutants. Plus, this filtration can get free of chemical pollutants in the water. It can also filter out glyphosate, PFOS, trihalomethanes, and PFOA, among other toxic chemicals.

However, it is a bit expensive, though. Weighing its benefits, it can give you more out of your spending. It is portable and convenient for use anywhere. It is also made of a quality and lightweight filter. Finally, it is long-lasting and can offer high performance for its sturdy materials.

LifeStraw Water Filter Bottle Adapter (Outdated)

If there is something LifeStraw is consistent about, it is in producing products that would provide clean and sustainable water in all areas. Lifestraw’s Universal Water Filter Bottle adapter kit is another success story.

You will find that this versatile water bottle adapter kit has two different-sized caps that can be used in a wide array of bottles. It will automatically turn your usual and traditional water bottle into one that can produce clean and safe water thanks to the water filters.

True to the brand’s objective of making water safe to drink, this universal water filter bottle can transform dirty and unsafe water to one you can drink straight from the bottle. You can also drink with confidence because you are sure that these filters can remove bacteria and parasites that are usually found in water.

It also rids you from the water impurities and chemicals like pesticides, herbicides, and chlorine’s taste and odor. This becomes possible thanks to LifeStraw’s membrane micro-filters that are constructed of hollow fiber membranes with a microscopic size pore of 0.2 microns. Water contaminants are usually sifted, allowing clean water to pass through because they are larger than the sifting pores. Aside from this, you’d always appreciate the discovery of activated carbon filters because of how efficient it is in the whole filtration system.

Perfect for when you travel abroad or when you go hiking or camping, you can always have peace of mind knowing that you’d have a filtration system at your fingertips. This also helps in the preservation of the environment as it helps reduce the use of plastic bottles. Not to mention, it also helps reduce costs because there is no need for you to keep on buying plastic bottles.

One very minor hiccup here is you must make sure that the tiny O-ring that secures it to the water bottle is tight and nice else, you might have some leaking problems. This is going to be a necessity for you, and you’d never travel without it again once you’ve experienced all the benefits it can offer you and even more. Customers also trust this brand in the United States and the world.

What Is A Water Filter For Travel/ Who Is This For


A water filter for travel is a portable device that allows you to drink purified water from virtually anywhere. These devices can take many forms. Some are designed to look like ordinary water bottles or personal water jugs. Others come in the form of a bag that you hang up high and let gravity do the rest. There are also travel water filters that look like large straws with built-in filter chambers.

Regardless of the type of travel water filter system that you have, they all work in the same way. These products allow the passage of water molecules through a semi-permeable membrane. Simultaneously, the layer prevents the passage of other molecules that are bigger than water molecules. These can include chemicals, toxins, bacteria, fungi, protozoa, parasites, and certain viruses.

Travel water filtration systems are ideal for anyone going to a place where the safety and quality of drinking water are uncertain. For example, hiking, camping, and backpacking through the wilderness will offer you very few resources for safe drinking water. Your only sources are streams, rivers, lakes, and other bodies of water. The problem is that you can never be too sure whether the water you are drinking is safe.

The same is true when traveling to a country or city where the water sanitation standards are questionable. You do not want to experience traveler’s diarrhea or other gastrointestinal problems because of unsafe drinking water.

Having a portable water filtration system lets you have that peace of mind whenever you travel to a place where you are not sure about the safety of the water. You can avoid gastrointestinal and other health issues while also addressing your inherent need to drink. You get to ensure your health and safety this way.

How Does It Work

A water filter for travel works like any other water filtration system. The only difference is that they are portable and often come with smaller filter elements. The main function of a filter element is the separation of molecules by virtue of their size. Filters are porous. They have very small holes like a sieve. The size of the holes has an impact on the effectiveness of the filter in separating different molecules.

Any molecule that has a larger diameter than the diameter of the filter hole will not be able to pass through this hole. As such, it will remain in that section of the device. Only molecules with a smaller diameter than that of the hole will be able to pass through. Since water molecules are tiny, they can easily pass through these holes. More significant compounds and specific biological agents will not pass through the filter.

Unfortunately, filters cannot prevent the passage of certain viruses through the membrane. Viruses can be as small as 20 nanometers to about 400 nanometers. Most devices on the market can only filter particles larger than 500 nanometers. High-end ones can filter particles as little as 100 nanometers. You still have viruses that are smaller than 100 nanometers that can get into the filtered water.

To address this issue, there are travel water filters that also serve as purifiers. These devices inactivate the viruses and other small microorganisms that may not be removed by the filter. Purifiers can make your drinking water a lot safer.

What Are The Different Types Of Travel Water Filters


We can categorize travel water filters into at least five different types. These include bottle, pump, gravity, UV, and straw water filter systems.

Bottle Filters

These look like any ordinary drinking bottle or water jug. The difference is that the lid features an integrated filter or purification system to help eliminate or reduce harmful water contaminants. These bottles are straightforward to use. Fill them up with water, and the built-in filter does the rest. It needs frequent cleaning, however. The filter cartridge needs regular replacement, too.

Pump Filters

A pump filter is almost the same as a hand pump that we use for transferring liquids from one container to another. This device comes with a hose that you dip into a source. The pump draws the water through the tube and empties it into a container. The water passes through a filter connected to the pump, allowing you to enjoy clean and safe tap water to drink. Pump filter water systems require a bit of elbow grease. However, they do provide an easy way to ensure safe drinking water wherever you are.

Gravity Filters

It is perfect for campers and hikers. This system consists of a bag, a hose, a filter, and a water collection container. You fill the bag with water and hang it high enough to let gravity do its work. Water flows through the hose, through the filter, and into the container, where you can later collect it for drinking. The issue here is the stability of the bag as it hangs. You do not want it to fall to the ground.

UV Purifiers

Purifiers are not filtering, although they do help in the inactivation of harmful microorganisms in water. UV purifiers are pen-like devices that emit ultraviolet radiation to kill microbes. You fill a glass with water, turn on the UV purifier, and dip it in the water. Wait about a minute or so, and you already have purified water. Keep in mind that UV purifiers run on batteries. It is always essential to keep them charged.

Straw Filters

These are the most straightforward yet most advanced travel water filtration systems available. They look like ordinary straws. You dip the straw in a glass of water and sip like you would any normal straw. The water passes through a built-in filter in the straw to remove contaminants or impurities.

Advantages And Disadvantages Of Using A Water Filter For Travel

Like any other product, water filters for travel can have distinct advantages that people love. Such products can also have downsides to them that one must weigh before making any decision to buy. The following are the most important advantages of a water filter for travel.

Good for the Environment

Ordinary water bottles are very convenient. You buy them, drink the water, and discard them any time you wish. Unfortunately, millions of tons of plastic water bottles end up polluting water systems and even the land. Using a portable water filter can help reduce the impact of plastics on the environment.

Very Practical

Portable water filters allow you to drink from virtually any source. You will never have to worry about upsetting your tummy because of the pathogens that may be present in the water. It is especially true for devices that have built-in purification systems. All you need is a source, such as a river or a puddle. Fill your device with water and let the filter do its thing.

Very Convenient

One of the most suitable ways to ensure safe drinking water is by boiling it. Unfortunately, it takes time to boil water in the wilderness. You need to boil the water for at least 15 minutes and then cool it down so you can drink it. In other words, boiling water is a hassle. Using portable water filtration systems eliminates such hassles and gives you safe and clean tap drinking water right away.

More Economical

Water filters for travel are indeed expensive. However, if you think about how many bottles of water you must drink every time you head outdoors, you will know that this is a worthy investment.

Not everything is rosy about water filters for travel. They do have downsides, too. These are as follows.

Limited Water Quantity

Some products can give you a minimal amount of filtered water at any given time. It can be an issue if you are very thirsty. You will have to improvise by storing the filtered water in separate containers. It will give you a backup in case you run out of water.

Slow Filtration

The filter of these units is smaller than what you can find in the home. As such, you cannot expect the screen to provide you with water at the same rate as a household water filtration system.

Buying Guide


Portable water filtration systems can be real lifesavers whenever you go to a place where the quality of drinking water is unknown or questionable. Unfortunately, picking the right water purifier to bring with you on your adventures can be challenging. Here is a straightforward guide on how you can choose the top-tier travel water purifier filter for you.

Consider the Filtration Technology

Most water filtration systems feature activated carbon filters as one of the filtering agents. It is ideal for the removal of bad taste and nasty odors from water. It makes the water more pleasant to drink. Carbon can also adsorb impurities such as heavy metals. There are also products that include other filtration technologies. An example is electro-adsorption. Electro-adsorption works like little magnets that attract particles in the water to keep it safe.

Check the Filter Pore Size

The effectiveness of a filter depends on the diameter of its individual ‘holes.’ If the holes are large, then you cannot expect the screen to remove small particles. Good quality filters typically have a pore size of at least 1 micron. However, a 5-micron pore size would be adequate in most instances.

Does it have a Built-in Water Purification System?

The pore size of standard filters does not prevent the passage of many viruses. These microorganisms can be as small as 0.02 microns. That is why it is essential to check the water filter for travel if it comes with a built-in water purification system. Some products use chemical tablets to inactivate viruses. Others use a device that emits ultraviolet radiation to kill viral species. Some machines incorporate silver compounds in their design. Silver can help neutralize viruses and other microorganisms that may pass through the filter.

Check the Water Capacity

Always consider the capacity of the water purifier for travel. It is especially true if you are going to pick a bottle filter type. It is often rare to find a bottle of water filter that can hold 24 ounces of water. You can get one that has a 15- or 16-ounce capacity. Straw filters are high because there are no limits to how much water you can drink.

Consider Filter Maintenance

As with any other product, water filters have a service life span. Some filters may last only several uses or a few gallons of water before requiring replacement. There are also water filters that are washable. Such products are perfect for people who want to economize. Unfortunately, the service life of the filter is based on the water condition and frequency of usage of the product. It would be most suitable to pick a product with a long-lasting filtration mechanism.

Consider Ease of Use

Some products are quite tricky to use. They can come with hoses and other parts that you will have to connect to before you can start using the device. Others may not come with an owner’s manual, too. Pick a system that you can use straight from the box.
