Our Top Pick


Katadyn Hiker Pro​

Filter water on the go with Katadyn Hiker Pro. The pump-style filter draws water even from shallow puddles and keeps sediments and microbes out with its 0.2-micron pleated glass-fiber filter media. Wilderness or wetlands, you stay hydrated always.

How To Pick A Portable Water Filter?

Included below are five of the main factors you need to check before deciding whether or not you should purchase a specific portable filter. Taking the following factors into consideration should make it easier for you to find the best portable water filter.


There are several types of portable water filters, but the ones you’ll likely encounter most are gravity, pump, squeeze, and straw-style filters.

Gravity filters are great because you don’t have to do that much work, but they can be slow. Pump filters will enable you to draw water even from shallower sources, but they tend to become tougher to work with as they age.

Squeeze filters are remarkably versatile, but many of them have to be paired with separate containers. The straw-style filters are very compact, but they aren’t ideal for producing a large amount of clean water.


To get an idea of how quickly the filter can provide clean water, you should take a look at its flow rate. The filters with higher flow rates are best if you want your thirst addressed as quickly as possible.

Contaminants Eliminated

Portable water filters that eliminate as many contaminants as possible would obviously be best, but at the very least, look for ones that specifically target cryptosporidium and giardia. These are parasites that can cause diarrhea and must be avoided at all costs when you’re outdoors.


Check to see how many gallons of water the filter can handle before it needs to be replaced. You will be able to find filters that can process so much water that they should essentially last for a long time. You don’t necessarily have to aim for that, but filters that can go through 200 gallons of water are good to have.

If it’s a straw-style filter that you’re considering getting, you don’t have to worry as much about how many gallons it can process since they only work on small amounts of water whenever they’re used.

Ease of Use

The portable water filter should be your ally outdoors and not your enemy. If it takes a lot of energy to get the filter set up, it may not be worth using. Pick one up that you can use easily so that you can get water on demand.

Katadyn Hiker Pro – Best Portable Water Filter

review of Katadyn Hiker Pro

The Hiker Pro Transparent Water Filter from Katadyn and what you’ll probably like the most about this product is its durability.

Durability: The manufacturers put a lot of thought into its design, ensuring that it will be able to withstand the rugged environments that you will likely encounter outdoors. The filter itself is protected by a durable container. Even if you drop it a few times, the whole thing should remain mostly intact.

The container itself is a bit small as it can only hold about 11 ounces of water, but it should still be enough to satisfy your thirst.

Type of Filter: This pump-type filter is something you will have to work yourself in order to get the clean water you need. Early on, the pumping is no problem. However, as you use this product more, the pumping can grow to become more difficult.

Contamination Removal: By using this filter, you can take out contaminants such as cryptosporidium, giardia, and different types of bacteria.

Lifespan: The filter itself should last for a while in your possession. The original filter included should be able to clean up around 300 gallons of water.

On-going Cost: Once the original filter is worn down, you can purchase a replacement filter for around $38. It’s a little pricey for a replacement filter, but it can process up to 300 gallons.

+ Durable container holds up well to drops.
+ Container can be easily cleaned.
+ Features activated carbon filter to improve the taste of the water.
Pumping can become more difficult over time.

Great for backpacking and travel, the Sagan Life XStream is what you can consider on your list if you are looking for a portable water filter. It is small, lightweight and packs in great features.

It also includes a spray pump which is a big plus when it comes to sharing clean drinking water and washing food and hands.

Contaminants Removal: The XStream uses its own proprietary filter. It also exceeds EPA purification standards therefore it is tested and proven. However, this filter is highly recommended to use the filter only on any non-salt water source. This means sources from rivers, lakes and streams.

The water filter removes and filters up to 99.9% of bacteria which includes salmonella, cholera, and E.coli. The XStream filter does not stop there, it is also capable of removing 99% of protozoan and parasites (including giardia and cryptosporidium), 99.9% of Virus and 95% of Lead.

Sawyer Micro Squeeze – Best Budget Squeeze Water Filter

review of Sawyer Micro Squeeze

Perhaps you’re among those people who prefer not worrying about how long their portable filters will last. You’d rather purchase one portable water filter and just continue using it for every outdoor trip.

The problem with this filter is that it can sometimes work very slowly. When used to process noticeably dirty water, it may take a while before this filter can produce the water you need to quench your thirst. It’s best to start filtering water using this product well before you get the urge to drink.

Lifestraw Flex - Best Collapsible Water Filter

review of Lifestraw Flex

LifeStraw is arguably the best-known brand in the portable water filter industry and with good reason. Their products are super compact and easy to use.

Take the LifeStraw Flex. It is one of the few collapsible water bottle with filter in the market.

The straw itself is also so small that it should fit easily in your pocket.

Lifespan: The biggest downside to this portable water filter is that the carbon capsule it uses has to be replaced often. Each replacement carbon capsule is only good for processing around 26 gallons of water. A replacement carbon capsule costs around $12.

On the plus side, the item itself should remain usable for a year and a half.

What Is A Portable Water Filter?

When you’re out in the wilderness, making sure that you have enough water to keep your body properly hydrated is crucial. You don’t want to suddenly collapse outdoors because you weren’t able to drink enough water.

The great thing about portable water filters is that they eliminate the need for you to bring bulky water containers. You can just go to a nearby body of water, use the filter, and after a short wait, you will have clean water for drinking.

The Different Types of Portable Water Filter

Although they all have the same purpose and functionality, many different kinds of portable water filters have been emerging for the past decade. Depending on your needs, it is great to know those when choosing the right filter. Below are some of the different types of portable water filter.

Straw Filters

Starting with the most popular and most compact portable water filters which are the straw filters. These consist of just a plastic pipe with the filters built in inside. It is quite easy and quick to use as well. Simply dip the straw in the unfiltered water source (like rivers or a jug with tap water) and sip directly.

The filtration system simply works right away as water passes through as you sip. Straw Filters also have their own disadvantages as well such as less thorough water filtering (some particles may still make it through), easy to clog and shorter lifespan. However, straw filters like Waterdrop have been seen with a long lifespan of around 100,000 gallons.

Bottle Filters

Bottle Filters are another type of portable water filters which functions similar to water filter pitchers. It consists of a bottle and a filter that is attached directly on the neck. An advantage found in bottle filters is that they are great at filtering heavy metals and viruses compared to the straw filter.

Of course, bottle filters also have its own disadvantages like its build quality (some are made of foldable plastic), and are much bulkier and may require more space when carrying it in your backpack. Overall, you get a water filter with great filtration performance at the cost of bulk size.

Gravity Filters

Another type of portable water filter that functions similar to a water filter pitcher. Gravity Filters consist of a container and a filter attached below. Utilizing gravity, the unfiltered water passes down through the filter.

However, there are some disadvantages that gravity filters have as well such as the slow filtration speed, and the likely contamination of your freshwater (occurs when filters are not sealed tightly). Gravity Filters are also required to be assembled which may not be a thing for some people.

Pump Filters

The most complex type of portable water filters. Pump filters consist of a hose and a tank for storing clean water. Once connected, you can start obtaining fresh water by vigorously pumping water from a water source. One of the biggest advantages of pump filters is that its filtration method may vary as it is capable enough to use filters with different purposes.

The downsides of using pump filters are quite noticeable as well includes vigorously pumping water in order to fill a small tank thus it can be laborious. Another downside is the storage capacity which some pump filters will only include a small tank which may not be enough for family consumption.

Why You Need a Portable Water Filter

When going on an outdoor trip like camping or hiking, it is very important to have access to healthy and clean water. So why do you need a portable water filter? While it is fairly easy to quench your hunger, you cannot function well without water.

  5. Legionella Pneumonia - A bacteria that is the common culprit of the Legionnaires’ disease. Symptoms include fever, muscle aches and cough. If untreated may result in death.

How Portable Water Filters Work

Although all types of portable water filters have similar goals that is to remove and filter contaminants from the water, they all do it in their own unique ways that differ from each other. Below are the types of portable water filters and how they work in order to provide clean water.

Bottle Filters - Bottle filters work by first placing water inside the bottle with untreated water. As you sip, the water will pass through the center filter attached to the neck of the bottle, filtering contaminants so when the water hits your mouth, it is already clean.

Gravity Filters - As exactly as they sound, gravity filters use the force of gravity to push the water as it filters contaminants from the water. The untreated water is stored on a water reservoir and when it is needed, it passes through a water hose with a filter attached.

Pump Filters - Pump Filters require effort from the user in order to achieve clean water. The user forces the water through the filter by pumping. The clean water is then transferred onto a small storage tank.
