Buying Guide: How to Buy a Portable Water Filter

Drinking clean water should be one of your priorities, no matter your location. Whether youre camping in the mountains or traveling in foreign countries, you should always make sure that the water you drink is clean and healthy. Portable water filters offer an easy solution to this problem. These models are small enough to fit in a backpack, and theyre efficient enough to clean every source of water.

But finding the right portable water filter can seem like a daunting task at times. There are a lot of models available on the market, and its difficult to tell which can perform better than the other. In the following section, we explain how to choose a water filter, how a water filter works, and why you should use such a filter when youre traveling.


As you could see in our short reviews, there is more than one type of portable water filter. Even though they lead to similar results, each type filters the water in its own way. Lets take a look at how they do it and the pros and cons of using each type of filter.

Straw water filters are the lightest portable filtration solution available now. Just like the name suggests, these filters usually look like overly large straws, and they work like straws as well. To use these filters, you just have to get close to the water source and draw in water through the straw.

Unlike a regular straw, the filter requires a more powerful draw in order to work, but the filtration process is really easy and straightforward. Straw filters use cartridges made out of the hollow fiber membrane. These fibers are tightly woven together, so the water has to pass through a lot of fiber layers before reaching the actual straw youre drawing on. The fibers are also very porous, but the holes in the fibers are very small.

Most membranes use holes that are 0.2 microns wide, so thats one hundred thousand smaller a 2 cm hole. The water passes through the holes in its way to the straw, but all the bacteria, viruses, and parasites in the water are larger than the hole, and they will be trapped and wont be able to pass.

Basically, all the elements that float in the water are too large to pass, so the water you end up drinking contains no residue or bacteria

Efficiently removes all sediment and debris

Removes the particles that cause the water to taste and smell bad

Efficiently removes bacteria, viruses, protozoa, parasites

The holes in the membrane get clogged with debris, sediment, and bacteria over time, so you have to change them.

Not very efficient at removing dissolved contaminants like chlorine, heavy metals, and pharmaceuticals

Pump filters are not extremely small, but theyre still small enough to fit in a backpack without taking up too much space. To use the filters, you have to connect a lead line to the water source and another line to a water recipient. You use a small hand pump to draw the water.

Now, some pump filters rely on ceramic filters, some use fiber filters, and some use one of these filtration techniques in conjunction with an activated carbon filter or even a block activated carbon. The fiber filters work exactly as the straw filters hollow membrane filters and mechanically stop the contaminants from reaching your drinking water. The ceramic filters also provide mechanical filtration. These filters are also porous, and their surfaces are usually covered in 0.5 1-micron holes. The water passes through the small holes, but all the contaminants are blocked. One of the advantages of using ceramic filters is that they can stop the asbestos that might contaminate your water.

However, a disadvantage is that some bacteria are small enough to pass through the ceramic filter and end up in your water. Another disadvantage is that the ceramic filter doesnt stop organic compounds from contaminating the water. Thats why some manufacturers use it in conjunction with an activated carbon filter. The activated carbon has millions of extremely small pores between its carbon atoms. Each gram of activated carbon presents a surface area of up to 2,000 square meters, and the contaminants in the water will be trapped on this surface. Here are the pros and cons of using an activated carbon filter.

Improves the waters smell and taste

Usually, an activated carbon filter has to be changed only once a year

The beneficial minerals in the water are not eliminated by this filter

The filter itself may become a breeding ground for the trapped bacteria if its not changed when its supposed to

The pores in the carbon granules are large, and they wont stop some bacteria species


Bottle filters have the advantage of being useful even when you dont have to filter your drinking water. You can simply remove the bottles filter cartridge and use it as a normal drinking bottle when youre certain your water source is safe and healthy.

When you have to drink from a water source thats most likely contaminated, you can simply put it in the filter cartridge and use the bottle as a filter. Most bottle filters rely on fiber filters to clean the water, but some models use solid block activated carbon filters instead.

The models that use fiber filters work just like the straw filters we described earlier, but instead of dipping the straw in a water source, youre actually using the bottle as a recipient for the contaminated water. The straw will filter out the contaminants and allow only clean water to reach the mouthpiece. Now, the models that use an activated carbon block filter to clean the water use a similar technology to the one we described earlier, only better.

In this case, the activated carbon has been treated and compressed to create a uniform matrix. This will allow the activated carbon to absorb more chemicals and reduce the size of their pores, making them more efficient at trapping bacteria and parasites.

Effectively reduce the heavy metals, arsenic, and other dangerous contaminants in the water.

Effectively blocks the bacteria and viruses from reaching your drinking water

Allows the beneficial minerals to remain in the water


Gravity water filters are great for campers, trekkers, and emergency preppers because they dont need electricity or a constant water supply to work. These models are perfect for those who like to travel in remote areas where clean water is not readily available. These water filters are usually made out of two containers placed above each other.

To use this filter, you pour water into the first container. Thanks to the gravity pull, the water passes through some filter mediums and ends up in the other container which is placed lower. The second container features a tap you can use to refill your water recipient.

Gravity filtrationusually relies on a combination of ceramic and activated carbon filters to clean the water. Thanks to the conjoined action of these filter mediums, the water produced is very clean and free of harmful contaminants.

Efficiently removes bacteria, viruses, protozoa, and parasites from the water

Can remove some herbicides, pesticides, and other man-made contaminants that may affect the water

Can filter out chlorine from the water

The filter cartridges can last for up to one year of use

Even though campers or hikers do not very frequently use them, there are some good UV portable water filters out there. These models run on batteries so that they will have higher operating costs. One of the advantages of using UV filters is that theyre very effective against bacteria and parasites.

Improve the waters smell and taste

Beneficial minerals are not removed from the water

Effective against bacteria, viruses, protozoa, and parasites

Their effectiveness decreases as the water is dirtier. The sediment and debris in the water can negatively influence the filters effect

Does not affect heavy metals or chemicals like chlorine

Why You Need a Backpacking Water Filter

Whether youre a wilderness or an urban explorer, having access to clean and healthy water should be your utmost priority. Few things can be as harmful as contaminated water. Sure, you might eat something bad, but while you can easily quench your hunger, you can barely function without water.

And unfortunately, there are a lot of harmful elements that you can find in untreated or poorly treated water. Here is a list of some of the most frequent water contaminants

E. coli E. coli infections cause fever, vomiting, abdominal pain, and diarrhea. The symptoms might appear right away, or they might appear within a week of the contamination

Giardia Lamblia You probably heard of giardiasis by now. Giardiasis causes nausea, stomach cramps, and diarrhea. The symptoms usually appear within two weeks of the contamination

Salmonella Salmonella infection leads to fever, diarrhea, nausea, muscle cramps. The symptoms can appear within 3 days of the contamination

Hepatitis A Hepatitis A is caused by a virus that can be found in water. The infection can lead to nausea, stomach pain, fever, and jaundice. The symptoms usually appear within 28 days of the contamination

Legionella pneumonia This bacteria causes the infection known as Legionnaires disease. The infection leads to fever, muscle aches, cough, and it may result in death if untreated.

Top 5 Things to Consider When Buying a Portable Water Filter

There are a lot of things you should take into consideration when youre shopping for a portable water filter or a water purifier. Heres what you should look for

Theres no point in buying a portable water filter if its uncomfortable to carry around when you travel. You should always take the filters weight into consideration before deciding on a model. Most portable water filters are small and compact, but their weight can vary according to their design, filtering technology used, and construction materials.

Every portable water filter will remove the contaminants from the water at a specific rate. Some of them will produce a couple of ounces of clean water every minute, while others can produce nearly 20 ounces of water in the same timeframe. Using a unit thats capable of filtering the water quickly can be an advantage if you plan on traveling or camping with a large group of people.

Like it or not, every filter cartridge has a limited lifespan. Some models might last for a few days, while others can be used with good results for a few weeks or even months. However, the highest quality portable filters use long-lasting filter cartridges. Some models will allow you to filter up to 264 gallons of water with a single cartridge, while others will clean up to 100,000 gallons of contaminated water.

Despite the fact that they are small and compact, not all portable water filters are easy to use. Some models come with detailed installation and priming instructions, and you might have to take the instructions with you when you travel to make sure you set them up properly. Other models are extremely simple to use, and you simply have to draw water through them and drink it, as if you were using a straw. Furthermore, themaintenance of the water filtershould be easy, too.

The best approach to finding a water filter that matches your budget is to set a budget before you start browsing for one. Just like all the other products you can buy, potable water filters come at different prices, and buying the most expensive model doesnt guarantee youre getting the best model. Plenty of efficient models come at low prices so that you can get a small and functional unit at a great price.

Despite the fact that most people use water filters and water purifiers as interchangeable terms, they do not actually mean the same thing. Heres a short definition of howwater filtration and water purification are different.

Water filters are more popular than purifiers, and thats because theyre more often than not more useful. These filters help remove or reduce the impurities you can find in the water.

The impurities they can clean or reduce include but are not limited to iron, nickel, lead, mercury, chlorine, chromium, copper, and more. Although they dont eliminate all the bacteria and viruses from the water, water filters can effectively reduce their number, and they can eliminate certain species of bacteria altogether. You can check out our article to learnhow to clean your water filters.

As a rule of thumb, the term water purifiers refers to the units that can remove all the bacterial, viral, and parasitical contaminants in the water. These models will do a great job of removing any bacteria, viruses, protozoa, and parasites in your drinking water, but they wont remove any other contaminants. This is why water purifiers are more difficult to find.

Most manufacturers prefer to develop purifiers that work in conjuncture with a water filter, so the models they develop will be able to remove both the bacteria and the sediment and chemicals that might contaminate the water.


As you can see, there are many types of water filters, but are all of them efficient in every possible scenario? Lets take a look at some of thebest backpacking water filtersin regards to backpacker types.

If youre one of the people who enjoy spending a lot of time in the wilderness, you probably know by not that you need awater filtering solutionif youre planning on spending a lot of time outdoors. There areways of purifying water in the outdoors. Sure, boiling the water is also a form of treatment, but water boiling is by far not the most effective treatment solution. Pump water filters are great for wilderness backpackers because they can filter a large quantity of water in a short time, giving you the possibility to pack your daily ration of water in a matter of minutes. Plus, you can consider usingwater purification tabletsin times of an emergency.

If you enjoy trekking and hiking, but you dont like carrying a large backpack when youre exploring the sights, you should use a straw or a bottle filter. These models are so small they will fit in every backpack. In fact, both of these filter types will most likely fit in a pocket, or you can simply carry them in your hands.

People who enjoy camping in their cars usually do so accompanied by friends and family. This is why they more often than not need a water filter thats capable of cleaning a large quantity of water. The perfect models for car campers are either gravity water filters or pump filters. Both these models have a good output, and they can quench the thirst of multiple people each day

Day hikers usually travel light. Some might not even carry a backpack at all, and if they do, the backpack is usually small and compact. This is why the best models for day hikers are straw or thebest filtered water bottles.

If youre an urban hunter, you might end up in some parts of the world that dont offer easy access to clean and healthy water. If this is the case, you must take the matter into your own hands and purify the water as you go. The right portable water filter choices for urban hikers are pump filters for those who travel in groups and straw or bottle filters for those who travel alone.

You can alsomake a DIY water filterfor half the price of other water filters.

As you could see in ourportable water filter reviewsand comprehensive buying guide, finding the right one is not very difficult once you know what to look for. These modes can be installed and primed with ease, and they will transform almost all sources of fresh water into clean potable water.

The first thing you should do when looking for thebest backpacking water filteris to think of how youre more likely to use it. If youre an urban explorer, you might be better off buying a small model.

But if youre looking for a camping water filter, it would be better to choose a model that offers a better filtering rate.
