How Portable Water Filters Work

How often do you see reality shows on how to survive out in the wild using natural resources around you? We shudder at the thought of ever having to drink our bodily fluids to stay alive. The good news for adventurers is that you don’t have to resort to such extreme measures!

Portable water filters are designed exactly for those times when clean water isn’t a stone’s throw away. Whether you’re camping, hiking or stranded in an emergency, they’re an important tool that could be the difference between life and death. The question is: how do they work?

The Science of Water Filters

Though there are various ways to purify, each device, system or product is based on the same theory: any molecules that don’t naturally belong in water are considered contaminants — but if they can find their way in, they can be forced out (1).

Water purification is a general term that’s used loosely to describe cleaning water of pollution. But, it’s a little more technical than that.

Purification is the process of chemically treating water to kill and remove pathogens and toxins from it, making it safe for consumption (2). Filters are generally — but not always — barriers added to plumbing, vessels or dispensers that only clean water molecules can pass through.

Filtration normally follows purification and is preferred because it can remove chemicals used in water treatment (3).

Water filters come in many shapes and sizes. Some, like reverse osmosis filters, push water back and forth through a membrane that traps contaminants. Activated carbon filters, as another example, absorb impurities and only let clean water through.

No matter the engineering, the result is the same — cleaner water that’s safer and healthier to drink. Water filters are capable of removing all sorts of impurities from water, from chemical toxins to dirt to germs.

Why Are Portable Water Filters So Special, Then?

One problem with filtration is that the most efficient filters are usually massive or set in place. Filtration systems in your home, for example, are attached to your plumbing. You can’t really take them everywhere you go and expect them to work.

It’s interesting because nothing changes when you scale water purification down. In theory, you can filter anything you drink from, just as you can chemically treat bottles of water or entire reservoirs. This is the idea behind portable filtration.

Devices are compact for easy transportation and use, but none of the benefits of bigger filters are lost.

Types of Portable Water Filters

As with stationary water filters, there are different variations. Though you’ll have cleaner water no matter which type you pick, you may find that one is better suited to you than others.

Product Image of the LifeStraw Go Water Filter Bottle with 2-Stage Integrated Filter Straw for Hiking, Backpacking, and Travel, Blue (LSGOV2CR45)

Water filter bottles are thought to be the easiest of filters for travelers. All you have to do is add water to them, and the bottle takes care of the rest. They’re reusable, affordable, and designed for everyday use.

The majority of these bottles use either fiber or activated carbon filters. Some use suction to pull water through the filter, while others absorb and trap contaminants. Carbon filters are preferred as they take care of more pollutants.

They’re not fail-safe though, and depending on the model, they might not filter out certain chemicals. Most are ineffective at tackling fluoride, nitrates, and cadmium.


  • Easy to carry and use.
  • Can be used daily.
  • Filters pathogens and heavy metals.


  • Limited in chemical filtering.
  • Maintenance required.

Water Filter Straw

These function the same way an ordinary straw does: place it into the water and sip. The difference is that a water filter straw is larger and heavier to accommodate the filtration system inside it. Because of their size, sipping will take more energy.

Water filter straws are extremely efficient at trapping pathogens and debris. A huge advantage is that they clear your water, removing tastes and odors from it too. They’re also very handy, as you can simply place them in whatever vessel you’re drinking from.

A drawback is that they clog easily and so need frequent maintenance.


  • No need to add water.
  • They’re affordable.
  • Improves the taste and odor of water.
  • Highly effective filters.


  • High maintenance.
  • Limited in filtering heavy metals and chlorine.

Gravity Filters

A gravity filter is simple to understand, but not as convenient as other portable devices. It works by setting up two containers, one above the other, and letting water drip down through a filter between them. Water is added to the top and dispensed from the bottom.

Different systems will use different types of filters, with ceramic and activated carbon featuring as favorites. They’re highly effective at removing most contaminants.

These are handy if you’re out camping or stranded, but you have to set them up and give them time to work. Also, be aware that they take up more room than other portable filters do.


  • Durable.
  • Filters most contaminants.
  • Little maintenance is necessary.


  • Must be put together.
  • Not as compact as other portable filters.

Water Filter Pumps

Product Image of the Survivor Filter Pro Water Purification System for Survival - Lightweight Hand-Pump Portable Water Filter for Backpacking Hiking Camping Water Filtration - Removal of 99.999% of Tested Virus Bacteria Parasites

Pump filters — as they’re sometimes called — aren’t much bigger than filter bottles or straws. They’re small and light enough to fit inside your bag or backpack and take little effort to operate. With these filters, a tube is inserted into a water source, pumped through a filter and consumed through a tube-like straw.

Common water filter pumps use either fiber or ceramic filters. The problem is that neither are efficient at clearing all pathogens, so some manufacturers add activated carbon.

These filters are excellent and handy, but be aware that you have to pump water through them manually.


  • Affordable.
  • Compact enough to fit in a backpack.
  • Can be used in any water source.


  • Manual pumping required.
  • Fiber and ceramic filters aren’t as effective as carbon.

Other Portable Water Purification

We recommend the above four because they’re the most effective, simplest to use, and easiest to carry. Some less popular alternatives include:

  • Chemical purification: Tablets are carried by the user and added to water to treat it as needed. It’s an effective solution but introduces chemicals you might be uncomfortable drinking.
  • UV filters: These are bottle-like containers with a battery-operated light. Though they work like a charm against biological contamination, they must be charged before use.
  • Backpack filters: Backpack water filters are excellent in disaster relief, but aren’t available from retailers and are a hassle to get your hands on. Since the objective is to have clean water in a fix, these aren’t an every-day solution.

Choosing the Best Portable Water Filter

With so many choices, how do you know which one to go for? We’re here to help. Consider the following to figure out which type is best for you:

What Will You Use It For?

Are you going on a camping trip or venturing to a third-world country with no water treatment plants in sight?

Where you use your filter matters the most because it tells you what needs filtering. If you’re out in the wilderness, bacteria and sediment will probably be your biggest threats. If you’re traveling abroad to populated villages, viruses become a significant concern.

Make sure that whichever filter you choose is capable of cleaning the relevant pollutants from your supply.


Nine out of the ten countries with the worst water quality are African, South-East Asian and Middle Eastern. The only exception is Haiti, which was severely impacted by the earthquake in 2010.

How Long Do You Need It For?

The capacity of your portable filter is also important. If you’re only spending a few days away from home, a filter that requires regular maintenance won’t be a problem. If you’re planning a long or unpredictable trip, it’s better to choose a filter that will be ready when you need it.

For extended trips, gravity filters are recommended. They’re the most durable, and so will need far fewer replacements than others.

What’s the Size and Speed?

If you’re traveling light, you don’t want a cumbersome filter. Our recommendations are all lightweight, and intended to fit into your backpack, luggage or even in an emergency kit.

The only exception to this is the gravity filter. They’re certainly not heavy, but they have multiple components you’ll have to keep track of. If you lose any components, you won’t be able to use it.

Also, think about how quickly you’ll need clean water. If it’s in an emergency, straws or pumps will be better. Bottle filters allow you to carry filtered water with you.

Can You Operate It Easily?

Is your filter going to help or hinder you? Gravity filters, as amazing as they are, have the extra hassle of assembly. They won’t do if you need clean water right away.

Regardless of the maintenance, straw filters seem to be the best choice in a fix. A drawback is that you have to sip on them, and can’t transport clean water using one. Bottle filters score well if you intend to carry water with you.

Before You Buy a Portable Water Filter

Portable water filters cost almost nothing and are an important tool, be it for survival or simply for camping fun. There really isn’t any reason not to get one, especially if you’re planning a trip or travel regularly.

That said, there are some things that portable filters can’t help you with. Understand their limits, and your journeys will be so much easier.

  • They’re not armor: If you’re traveling to a high-risk area, remember that these filters won’t protect you from bugs or airborne pathogens. It’s of vital importance that you get the necessary vaccines before you travel. Some countries won’t allow you entry if you don’t (4).
  • You still need to bathe: Portable water filters help because they’re compact, but this can work against you. You’ll have to make a different plan for washing yourself, as these devices won’t give you a sufficient amount of water.
  • Different water composition: Regardless of which filter you use, or how effective it is, the water will probably taste different to what you’re used to. Many factors influence how water tastes. Don’t be surprised if the water you consume in other countries doesn’t taste as you expect (5).

Quick Tip

If feasible, boiling water is a good way to purify it. In fact, distillers make use of this method. It’s not the most convenient, but it can make a world of difference in your travels (6).

The Best Portable Water Filter Reviews of 2022

We’ve chosen our favorites based on convenience, efficiency, and customer feedback, to bring you an ultimate list of well-rounded options to choose from.

1. Platypus GravityWorks Water Filter System

Highest Capacity

Our best example of a portable water filter stands out because of its large 4-liter capacity. Fast-working, it can filter up to 1.75 liters per minute, which means you get a full bag in under five minutes.

The quality standards with this model are high; it’s tested to guarantee NSF and EPA standards and to remove almost 100 percent of pathogens.

Operation is easy. All you have to do is scoop water into it, close it, and leave it to work. This system includes two 4-liter reservoirs and a hollow fiber microfilter. You also get a shutoff clamp, storage sack, and all necessary components.

The Pros

It Works Fast

In an emergency, time is everything. At almost 2 liters per minute, this is one fast filter. You don’t have to wait long for clean water, and if you’re far from home, that means everything.

It helps even more because this is a gravity water filter, so you’ll spend time in set up. This product’s speed compensates for that, and the difference is significant.

Large Capacity

Technically, this system has an 8-liter total capacity. Four for dirty water, and four for clean. That’s a lot of water — easily more than you can carry in a bottle.

You never know when you’ll need the extra, so consider this one if you’re looking to make the most of your filter. Despite this, it’s still compact, so you won’t sacrifice space in your luggage or backpack.

Filters Pathogens

This is a must-have if you’re going into high-risk areas. The filters are tested to meet NSF standards and to clear 99.99 percent of bacteria and protozoa from your supply. Pathogens that this system can remove include, but aren’t limited to, E.coli, salmonella, and cholera.

The Cons

It’s Fragile

Many customers say that while they absolutely love the filter, it’s flimsy and fell apart relatively easily. The problem seems to be in the bag for dirty water, which tears along the straps.

Some buyers noted that after complaining to the manufacturer, replacement products were sent. It was likely a bad batch rather than a design flaw.

Filling Is Tricky

Scooping water into this system is effortless, but getting it full may be a different story. Some users say it’s challenging to fill up. This isn’t a common complaint, but it is something to be aware of.

Additional Specs

Capacity 2 x 4 liters
Filtration rate 1.75 liters per minute
Weight 0.6 pounds
Dimensions 3.25 inches by 9.5 inches
Filter type Hollow fiber
Features/accessories All necessary components, storage bag, shutoff clamp

2. LifeStraw Personal Water Filter

Most Durable

If you’re planning a long trip or will spend time away from treated water, you don’t want to waste time on maintenance. The LifeStraw filter is made to last, making it stand out from other straw filters. This will see you through a whopping 4,000 liters of water before the filter needs replacing.

Built from eco-friendly BPA-free and recyclable plastic, it uses a hollow fiber microfilter. Included with the straw are a mouthpiece cap, bottom cap, and a carry strap.

The straw filters 99.99 percent of bacteria, parasites, and microplastics. It’s a great choice if you’re headed to heavily polluted zones.

The Pros

Long Life

LifeStraw estimates that this filter will last up to five years if used correctly. You’ll save an immense amount of time and money because you’ll need fewer replacements. This is especially impressive since it can filter up to 4,000 liters of water — much more than competing straws.

Good Cause

For every purchase, LifeStraw supplies a year’s worth of clean water to a child in need.

These filters are environmentally friendly too since they’re made from recyclable plastic. It’s a survival tool, a helping hand, and planet-saver all rolled into one.

Filters Plastic

An unconventional advantage is that this straw filters microplastics. Not many competitors can say the same, so this one is certainly worth a consideration. It filters almost 100 percent of bacteria and parasites too.

The Cons

It’s Tiring

Customers say that this is an effective filter, but that it’s tiring to draw water from it. Sipping takes some physical effort and will probably be uncomfortable if you’re unaccustomed to straw filters. A few buyers recommend this for emergency scenarios rather than frequent filtration.

A Few Limitations

The straw has a long life and is an excellent filter, but it falls short in some areas. It doesn’t easily fit into water bottles, and no provision is made for attachments to water bags or reservoirs.

There aren’t many extras included with the product either. Customers aren’t heartbroken by this, but some wish it had more to offer.

Additional Specs

Capacity Up to 4,000 liters
Filtration rate Not applicable/instant
Weight 0.10 pounds
Dimensions 1.2 inches by 9 inches
Filter type Hollow fiber microfilter
Features/accessories Mouthpiece cap, bottom cap, detachable lanyard

3. Etekcity Water Filter Straw

Best Filtration

Who’d have thought that a compact filter straw could have the same filtration power as large filters? This one does, because it uses three-stage filtration for more efficiency and safety. We also like that it’s FDA compliant.

You can use it for up to 1,500 liters of safe water. It uses a hollow fiber membrane and a carbon filter to clear 99.99 percent of microbes, heavy metals, and chemicals.

Designed to attach to hydration reservoirs, you can use this straw with almost anything. Included are a water pouch, pre-filter, backwash device, and an extension tube.

The Pros

Lasts Long

The filters clean as much as 1,500 liters before they need replacing. This is an excellent and convenient tool to have on extended trips, as maintenance won’t be an urgent concern. It helps that a backwash device is included for easier cleaning and clog prevention.

Triple Level Filtration

Why use one filter when you can have the power of three? This straw comes with a pre-filter, a hollow fiber filter, and a carbon filter. It combines the best of all words for extra-effective filtration.

We feel this is necessary if you’re in high-risk areas — the extra safety gives peace of mind.

Filters Almost Everything

There’s little that this straw can’t take care of. It filters out heavy metals, chlorine, volatile organic compounds (VOCs), debris, and pathogens. You’ll be protected from a range of bacteria and contaminants, and your water is made healthier because of it.

The Cons

Difficult Suction

According to a few buyers, sucking water through this straw is hard work. They’re pleased with its effect and note visible changes in water quality, but say drinking through the straw is tiring.

The majority of users are highly satisfied with the result of this filter, so don’t place too much emphasis on this.

Hard to Fill

Some customers say that, as with the Platypus GravityWorks, filling the included water bag is a bit of a hassle. This won’t matter if you’re drinking directly through the straw — the use of the bag is not a necessity.

Additional Specs

Capacity Up to 1,500 liters
Filtration rate Not applicable/instant
Weight 0.1 pound
Dimensions 1.2 inches by 6.2 inches
Filter type Triple-stage; pre-filter, hollow fiber, activated carbon
Features/accessories Pre-filter, foldable water bag, extension tube, backwash device, manual included

4. Survivor Filter Pro Water Filter

Best for High-Risk Zones

You may have noticed that, so far, our favorites don’t filter viruses. This pump does, so choose it if you’re traveling to areas where risk of exposure is high. The filter also takes care of bacteria and heavy metals, so it’s a well-rounded choice.

It’s built from materials used in car manufacturing and the Apollo space mission, so you know it’s durable. Three-stage filtration works at a rate of 29 milliliters per minute. You can drink the water directly, pump it into a tumbler or attach it to a hydration pack.

Included are a drinking cup, travel bag, user manual, and all components and tubes.

The Pros

Filters Viruses

Most other pumps can’t handle viruses or are limited to the contaminants they can manage. This model clears heavy metals (including lead), bacteria, and viruses from your supply.

It’s Durable

If the materials are good enough for car manufacturers and astronauts, it’s certainly built to last. You’re less likely to damage or break this pump because it’s made of strong stuff. On top of this, it’s BPA-free and weighs less than a pound.

We were stunned by this filter’s 100,000-liter capacity. It goes without saying that this filter will last a long time and is worth investing in for its durability alone.

Filters Lead

Lead is a horrible contaminant, and difficult to filter out of water. Not all filtration systems are capable of removing it, so kudos to this one!

In addition to lead, it purifies your water of most contaminants and is one of the more thorough filters we found.

The Cons

It Costs More

Compared to the straws we showcased, this filtration system isn’t cheap. But its price is not at all unreasonable when you consider how effective it is. The sophisticated filters and high-grade material will cost you extra, and so this isn’t a budget option.

Somewhat Slow

You don’t have to wait for ages for this pump to work, but its filtration rate is slow compared to the Platypus model.

The straws we picked are also faster as they take instant effect. With this product, the manual pumping could take a while, and its filtration rate leaves much to be desired.

Additional Specs

Capacity Up to 100,000 liters
Filtration rate 29 milliliters per minute
Weight 0.1 pound
Dimensions 1.2 inches by 6.2 inches
Filter type Triple-stage; pre-filter, hollow fiber, activated carbon
Features/accessories All necessary components and tubes, drinking cup, travel bag, user manual included

5. Sawyer Water Filtration System

Best for Leisure Travel

If you’re interested in a portable filter for hobbies or leisure, this product will do well. Customers love its convenience and say it’s efficient and easy to work with.

It only weighs 0.1 pounds, and the caps are designed for easy placement and removal. A hollow fiber filter combats pathogens well, clearing 99.99 percent of bacteria and protozoa. This system also removes 100 percent of microplastics from your supply.

Extras include a cleaning plunger and coupling, as well as a storage bag.

The Pros

Great Functionality

Buyers praise the ease of use with this filtration system. Though some people say that its design could have been better, this filter has many compliments for its simplicity. The cleaning tools that are included are a big bonus that buyers appreciate.

Filters Microplastics

If you’re camping, hiking or spending a few days out in nature, this filter is more than enough. Almost 100 percent of bacteria and protozoa are removed, and it clears all microplastics from your drink. It’s perfect for leisure travel and hobbyists looking for that extra boost in safety.

Excellent Accessories

These are some of the handiest extras you can get from a portable filter. Rather than focusing on extra bladders or straps, Sawyer added storage bags and cleaning gear. All this adds to the overall durability of the filter and could even eliminate the need for premature replacements.

The Cons

Limited Filtration

Sediment is a problem customers mention, and this filter won’t clean heavy metals, viruses or chemicals from your water.

For this reason, we recommend using this one for hobbies only, as it probably won’t hold up in high-risk zones.

Additional Specs

Capacity 2.0 liters
Filtration rate Unspecified
Weight 0.1 pounds
Dimensions ‎9.5 inches by 4 inches by 3.5 inches
Filter type MINI hollow fiber membrane
Features/accessories All necessary components and tubes, cleaning plunger, cleaning coupling, storage bag

6. Membrane Solutions Personal Water Filter Straw

Best for Sediment

Here’s a well-rounded filter that can help you out in a fix. The activated carbon purification which uses a four-stage system works against pollution, odor, chlorine and organic chemicals, and debris bigger than 0.1 microns. It’s a great tool to have in case of emergency, and it’s good value for money.

This system meets EPA standards, is built using food-grade plastic, and is BPA-free. You can filter up to 1,500 liters per filter with this one, and it comes with a 450 mL per minute flow rate to ensure optimum water flow.

The Pros

Cleans Sediment

We like that the four-stage filtration manages water pollutants such as pollen, bacteria, algae, chlorine and organics chemicals as well as the water scent. The activated carbon filter (third stage) and hollow fiber ultrafiltration membranes (fourth stage) improves the taste and appearance of your drink. In our opinion, this is a wonderful filter for both leisure and emergencies.

Value for Money

Compared to some other water filter pumps, this one comes at an affordable price without compromising on efficiency. It’s a high-quality, powerful product that saves you money. We recommend it if you’re interested in a water pump on a budget.

Lighweight Companion

Weighing less than a pound, this can be used during trekking or camping. Nevertheless, despite its size, it doesn’t compromise its quality with its four-level of water filtration system.

The Cons

No Viruses

It does a great job of filtering bacteria, but it won’t manage viruses. Perhaps it’s better to keep this one for domestic travel rather than high-risk adventures.

Additional Specs

Capacity Up to 1,500 liters per filter
Filtration rate 450 milliliters per minute
Weight 0.125 pounds
Dimensions 6.7 inches by 1 inch
Filter type 4-stage filtration UF membrane; coarse filter screen, medical grade PP cotton, activated carbon, hollow fiber ultrafiltration membranes
Features/accessories High flow rate and compact size

7. LifeStraw Go Water Filter Bottle

Best for Daily Use

Are you looking for a filter that you can carry with you everywhere you go? If so, this filter bottle could be ideal. Another by LifeStraw, it filters out bacteria, parasites, chlorine, and other chemicals such as pesticides.

It’s made to improve the taste, odor, and appearance of your water. The bottle is BPA-free, and, as is standard for LifeStraw, is made from recyclable plastic. So long as you remove the filter, it’s dishwasher safe too.

Don’t forget that LifeStraw gives back and that you’ll help a child in need with every bottle you buy.

The Pros

Filters Chemicals

This is a great filter to have in emergencies, but it’s excellent for everyday use too. It filters chlorine and other chemicals like pesticides and herbicides from your supply. You can use it to clean your tap water, so you always have healthy water on the go.

Easy Maintenance

Ultimately, this is just a water bottle, so maintenance is not difficult. Rinse it as you would any other drinking vessel, or pop it into your dishwasher if you want to save time. It’s made from BPA-free plastic, so it’s reusable and will last you a long time.

Better Water

Because it filters out chlorine and other chemical treatments, your water will taste and smell so much better. If you’re into hydration but don’t want a large or expensive machine installed, this is an excellent budget choice.

The Cons

Regular Maintenance Needed

If you plan on using this bottle regularly, you must take extra care to maintain it. Your filters will need frequent replacing, and you’ll have to clean them after every use. Remember that this bottle is dishwasher safe, though, so this doesn’t add too much effort.

Sipping Is Hard

So long as you realize that this is different from a standard water bottle, you won’t be surprised by this. Drinking isn’t as smooth as it would be from a plain bottle, so you’ll need some energy to draw the water out. But it’s a small price to pay for the improved water.

Additional Specs

Capacity 0.6 liters
Filtration rate Not applicable/instant
Weight 0.49 pounds (filter included)
Dimensions 9.25 inches by 3.14 inches
Filter type Two-stage hollow fiber and carbon
Features/accessories Filters, cap, silicone mouthpiece, carabiner
