best portable water filter

If you love backpacking, camping, and trekking, you should look for the best portable water filter. When you go places, it might be hard to locate a clean water source, which can be a problem. We need to stay hydrated wherever we are. It is why it’s crucial to find a portable water filter that works and straightforwardly supplies us with clean, fresh water.

  • Contaminants Removed: A filter should remove as many impurities from the water as possible and guarantee a safer and more pleasant drink. Hence, a portable water filter that eliminates as much as 99.99% of contaminants is better than a unit that only reduces them by 93%.
  • Filter Lifespan: Nobody wants a single-use portable water filter, especially when outdoors. The filtration system must be reusable, allowing backpackers and campers to enjoy clean and safe water on the go for many years. A 5,000-gallon filter will always be a better choice than a 1,000-gallon unit.
  • Ease of Use and Cleanup: A portable water filter must be effortless to use and hassle-free to clean. Otherwise, you will be better off buying bottled water. Straw-style portable water filters are the most suitable because their simple design affords maximum convenience on the go. Sadly, cleanup can be tedious if you are not careful with your choice.

However, it can be daunting to choose one without a clear idea on the top picks on the market. This guide is for you! Read for the top 11 picks, each with distinct features and qualities. Let’s get started.

Top 11 Portable Water Filter Reviews

1. LifeStraw Personal Water Filter

The LifeStraw Personal Water Filter was designed with emergencies and natural disasters in mind. It acts like a straw that you immerse into a source and drink. It incorporates the same innovative features in modern water filters like having no moving parts and requiring no batteries, but it also basically needs zero maintenance.

It is built to be sturdy, durable, light, and compact at only 2 ounces. It can be easily stowed away into a pocket or backpack without worrying too much about breaking the device.

This water filter uses a 0.2-micron filter that can remove 99.99 percent of bacteria, other parasites, and microplastic from water. The filtration membranes are made of hollow fiber that is chemical-free. Performance is on par with leading filtration systems, as it can transform dirty water to clear and filter bacteria that cause some of the most common illnesses from drinking filthy water.

It excellently eliminates pesticides along with all other harmful compounds. One cool feature of the LifeStraw Personal Water Filter is its activated carbon capsule, which reduces chemical contents and toxic organic matter, thus improving the taste and eliminating bad odors.

LifeStraw Personal Water Filter has no replaceable parts. It can filter up to 264 gallons of water (1,000 liters). It is equivalent to the average amount of water a person drinks in a year. After that, it will stop filtering, and you discard it. Backflushing it to clean the filter requires merely blowing water back out.

The LifeStraw Personal Water Filter has a beautiful portable water filter bottle that houses a two-stage LifeStraw filter. This option lets you dunk the bottle in any water source and sip through the mouthpiece. It also gives you the convenience of storing clean water or sharing it with others.

2. Sawyer Products Water Filtration

Sawyer lets you experience the lightest and most compact system to use, literally. The Sawyer Products MINI Water Filtration System weighs in at only 2 ounces but delivers heavyweight performance.

Considered as one of the most compact filters available on the market, it is small enough to fit into the palm of your hand. But you’d be surprised by its performance, flexibility, and ease of use. It can even let you drink straight from a lake or stream by merely using a straw that comes with it, making it the perfect on-the-go water filter.

Its thick hollow fiber membranes with small inner diameters make them 75 percent stronger than other membranes and allow fast flow. It uses a top-notch 0.1-micron filter that removes 99.99% of all kinds of bacteria and protozoa. It is very convenient to use. Just fill your water bottle or the included reusable pouch, screw the filter to it, and start sipping. Its screen can be attached to most water bottles.

The MINI Water Filtration System lets you do a little bit of maintenance by using a cleaning syringe to backflush the filter. It is a neat feature for removing sediments from the screen and helps make the device last for a long time while maintaining its high flow rate. Sawyer claims that the filter can be back-washed continually to restore up to 98 percent of its flow rate.

One drawback of this water filter is that the collapsible squeeze bag that comes with it can break over time, especially with heavy use. So extra care should be taken when squeezing the bag to get the desired flow rate. But this does not keep us from recommending this water filter, as its compatibility with water vessels can surely more than makeup for it
What We Like
  • Compact and ultra-light at just 2 oz
  • The plastic straw that lets you drink directly from the source
  • Convenient and straightforward to use
  • Easy to maintain and comes with cleaning plunger
  • Outstanding filtration.
What We Don’t Like
  • Collapsible squeeze bag can break over time

3. Membrane Solutions Straw Water Filter

Outdoor adventurers and homeowners looking for dependable portable water treatment systems should stop their search and take a look at the Membrane Solutions Filter.

Like LifeStraw, this filtered straw device offers unimaginable water contaminant reduction rates. It empowers campers, anglers, backpackers, and other adventurers to travel to remote locations and explore nature.

I can connect the filter to a squeeze bottle and never worry about dehydrating myself again. Campers can fetch water from the river or lake, pour the liquid into a plastic or canvas bag, and connect this product to create an improvised gravity water filter. Of course, drinking water from any source is a cinch because this device works quickly.

Water-borne diseases are the least of my worries because this product’s five-stage filtration mechanism guarantees a 99.99999% reduction of water contaminants. The water I drink will be free of silt, sediment, and solid particles. Tiny organisms, chlorine odor and taste, and harmful substances will never bother a camper’s water drinking.

Its 0.1-micron membrane captures the tiniest substances and microorganisms, while its polypropylene fibers and coconut shell-activated carbon work to absorb unwanted molecules and compounds.

Surprisingly, its ultra-fine semipermeable membrane does not impair the water filter’s flow rate. It can still deliver about 19 ounces of safe, clean, and pleasant-tasting water per minute. And the filter can process 1,320 gallons of “dirty” water before it heads to the garbage disposal system.

Although I appreciate this portable water filter’s SGS-tested and EPA-certified contaminant removal claims, I wish it also has validation from NSF or WQA. Still, I’m confident about water filters and purifiers that have been tested independently.

Overall, this portable water filter remains an excellent alternative to the leading brand. It has enough bells and whistles worthy of consideration.

What We Like
  • 1,320-gallon filtration capacity with a 19 ounce/min flow rate
  • 1-micron filter pore size for 99.99999% contaminant removal
  • Five-stage water filtration system with PP fibers and coconut carbon
  • Works quickly, easy to use
  • SGS-tested and EPA-certified
What We Don’t Like
  • No NSF or WQA certification

4. The Survivor Filter PRO

The Survivor Filter PRO uses a triple filtration system with a 0.01-micron filter that removes bacteria, parasites, chemicals, heavy metals, and even viruses. The company claims it is the best independently tested filtration level available on the market, and backs it up with an impeccable consumer satisfaction rating, including every online portable water purifier review.

The Survivor Filter PRO was tested to remove 99.99 percent of bacteria and protozoa (Parasites, Giardia, Cryptosporidium), 99.99 percent of the virus Phi X-174, and 99.5 percent removal of Lead and Mercury. These numbers place the Survivor Filter PRO on top of the competition along with an unmatched ability to remove heavy metal compounds. The company says its carbon filtration is 20 times more efficient than the ones on the market and even dares you to ask for copies of its test results.

Sure enough, the performance of the Survivor Filter PRO does not disappoint. Its flow rate is super-fast at 17 oz per minute, making this water filter perfect for the whole family.

Interestingly, the Survivor Filter PRO shell is made from ABS material (the same material used on helicopter blades and car bumpers). The filter is made of long-lasting medical-grade Polysulfone. You can expect a very tough, durable device that should last for a long time when taken care of.

The Survivor Filter PRO is simple enough to use. You can use it for drinking directly from a water source, using its attached cup or any portable hydration pack. This water filter is not as lightweight and compact as some of the competition but is considerably light and compact and remains an option for travel or emergency. It is also one of the few water filters on the market capable of filtering viruses using its 3-stage filtration technology.

One drawback of this water filter is that it uses a carbon filter to reduce chemicals in the water. Carbon filters work by absorbing chemicals instead of catching and filtering them out. Thus, it has a lifespan and will need to be replaced eventually. The company claims that its carbon filter’s lifespan is about 2,000 liters. This amount equals the amount of water an average person drinks in 2 years. That’s not bad at all. And if the filter gets clogged, you can backflush it to restore its performance continually.
What We Like
  • Convenient to use
  • It can filter viruses
  • Great flow rate
  • Long-lasting carbon filter
  • Made of durable material
What We Don’t Like

Portable water filtration reviews garner a high score for the Katadyn Vario Water Filter, which performs very well and offers one of the fastest water filtration available on the market. Use this filter to avoid drinking contaminated water again.

The Katadyn Vario was designed with convenience in mind. Using dual-piston technology, it can pump up to 1 liter per minute. Because of its high flow rate, we recommend it for backcountry family or group travel.

In addition to a high flow rate, the Katadyn Vario Water Filter offers a nice feature of setting filtration speed; a fast option that relies solely on the first glass fiber filtration and a slower speed option that uses a ceramic disc as a prefilter, thereby extending the lifespan of the unit. Even at the slow setting, the water filter can still pump out 1 liter of clean water in just 47 seconds, which is impressive. It features a replaceable carbon filter that reduces harmful chemicals and eliminates bad taste and odor.

This water filter can filter up to 2,000 liters of water before needing filter replacement, which is very good compared to other filters in its class. Besides the well-designed pump handle, the Vario seems to be a well-built and durable pump.

But one disadvantage of this water filter is that it is comprised of various components that can be taken apart. The parts may need maintenance over time, like cleaning and lubrication, as some reviews brought up leak problems, especially along with the filter housing. It is also on the heavy side when compared to other compact water filters to filter contaminated water on the market. But for those who don’t mind the extra bulk and weight and has time to care for their device, the Katadyn Vario Water Filter is one of the most suitable water filtration system for small groups. They want a fast, convenient, efficient, and reliable tool.

How Does It Work

It does not work in a complicated manner but is easy to use. It works to filter debris, protozoa, sand, silt, and even tiny microbes, depending on the model selected. However, it might be clogged for repeated use, so it needs replacement or cleaning. If you’re looking for a reliable portable filter for your adventures and outdoor activities, you might want to get started in the selection process using the reviews we’ve featured earlier in this guide.

What Are The Different Types Of Portable Water Filter


The next thing you might want to know about portable water purification systems is their types. As you know by now, you can find so many water filters on the market that you can use for backpacking, hunting, fishing, trekking, and hiking. There are also those that fit people who love car camping. To give you a reference, here are some of the most common types of portable filters to find on the market.

Straw Filters

These portable water filtration systems are the most common and handy solutions to find. As the name suggests, these filters look like straws. They also work like straws. However, it would be best if you were as close to the water source as possible to use it to draw in the water through it. Many of these filters use a hollow fiber membrane as the filtration component. They are woven tightly so that water passes through the layers before reaching the filter straw from where you will be sipping water. The holes in these fibers are small, but the fibers are porous.

Many of the membranes are made with holes with 0.2 microns in size. In this case, the parasites, viruses, and bacteria are larger than the holes so they will not be able to pass. They will just be trapped for effective filtration.

Pump Filters

They are larger than straw filters, but they are still handy. They can fit into your backpack without taking up much space. In terms of its mechanism, you need to connect the lead line to the water source, and then connect the other line to the recipient. To draw the water, you need to use the pump with which it comes. Some filters use ceramic, but others use fiber filters.

Others use any of these filtrations plus an activated carbon filter/block activated carbon. These pump filters work by offering mechanical filtration, preventing the contaminants from getting into the water you’re drinking. The contaminants are blocked. It can also block the asbestos that can get into your drinking water. On the downside, these filters might not be able to filter some bacteria, which can be small to pass through the filter. Thus, they will reach your drinking water.

Bottle Filters

These filters are also a personal water purifier for many people who love the outdoors. They can be useful even if you don’t want to filter water for drinking. This bottle can be used as an ordinary water bottle, too. But when you’re in a place where water is unhealthy or unsafe, you can just the filter cartridge back to filter the water. These filters make use of fiber filters to filter the water, but then, some others use block-activated carbon filters.

Gravity Filters

Another common filter, gravity filters, are chosen by emergency preppers, trekkers, hikers, and campers because they’re simple to use. They don’t require a constant water supply or electricity to work. They are for those who frequently travel in remote areas where you cannot find clean water. Most likely, these filters are engineered with two different containers, which are put above each other. You must put water in the first container in these portable water filter systems. The water will then pass through the filter medium before it ends up in the next container. Many of these systems also have a tap that you can use to refill a bottle or another recipient.

UV Filters

These models operate on batteries, so you might have to spend higher on their cost. But then, these filters are perfect for filtering down parasites and bacteria. They can also improve the taste and smell of the water and can work fast.

Buying Guide


Just like when buying a top-quality portable water purifier, you might also be thinking of ways on how to select the right filtration system that fits your preferences, needs, and purpose. As said, you can find so many of these filters on the market. Comparing which one will match your needs can be hard without comparing the different filtration systems on the market. It is why we have prepared a handy guide to use as a reference.

You must pick one that is handy that you can fit in your pocket or backpack or hold with your hand, depending on what your preference is. You can go ahead and compare the different filters we’ve featured earlier to determine the most portable one to fit your preferences.


Speaking of portability, you must pick a lightweight filter so that you can bring it conveniently in backpacking, hiking, trekking, hunting, or fishing. Avoid filters that will pose discomfort to carry around when traveling. It is why you need to consider the weight when figuring out which filter to buy. Check for those that are compact, small, and handy. However, you should also note that the design can affect the weight of the filter that you’re buying. It might also vary based on its construction material and filtering mechanism.


Take note that the filter can remove contaminants from the water source, but the rate will depend on the model that you have chosen. For example, some portable filters can produce some ounces every minute. On the other hand, some faster models can clean as much as 20 ounces of water at the same time as others can.


Know that cartridges have their lifespan. It just means some might last longer than others can. Some can be used for months, but others only for weeks. Nevertheless, you can find those that can filter at most 264 gallons of water, while the others will be able to clean at most 100,000 gallons of water.


You should also take note that not all portable filters are easy to use. That is why you should look for those that come with detailed use and priming instructions. You must also find those that are very simple to use, such as that allowing you to use a straw to draw in water, such as straw filters.

Similarly, the compact LifeStraw can remove up to 99.999999% of bacteria and 99.999% of parasites, microplastics, sand, parasites, and dirt. These small water filters use the same ultrafiltration technology as the Membrane Solutions, albeit with a smaller pore size (0.02 vs. 0.1 microns).

Sadly, companies can claim their smallest and most portable water filters are 99.9999% effective in removing water impurities without offering verifiable proof. Hence, you might want to be wary of products that make such claims without NSF, WQA, or EPA certification.
