The Best Portable Water Filter Reviews of 2024

You now know more about portable filters, so it’s time for our portable water filter reviews. We chose these products based on their effectiveness, size, capacity, and ease of use to ensure you have a varied list of portable filters to choose from.

Platypus GravityWorks Water Filter System

Highest Capacity Portable Water Filter

This portable Platypus water filter stands out because of its generous 4-liter capacity. It can filter up to 1.75 liters per minute, which means you can fill a storage sack in less than five minutes.

This model meets NSF and EPA quality standards and removes almost 100% of pathogens.

Operation is easy. You only need to pour water into it, close the lid, and leave it to work. This system has two 4-liter reservoirs and a hollow fiber microfilter. You also receive a shutoff clamp, storage sack, and all necessary components.

What We Like

It Works Fast

In an emergency, speed is everything. At 1.75 liters per minute, this is one fast filter. You won’t have to wait long for clean water, so you know you can depend on this filter when you need it most.

This is a gravity water filter, so you will spend some time setting it up. Its speed compensates for that setup time, providing filtered water far more quickly than most models.

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 — significantly more than you can carry in a bottle.

You never know when you will need extra water, so consider this filter if you want to keep some at the ready. Despite its capacity, it is still compact, so you won’t sacrifice space in your luggage or backpack.

Filters Pathogens

Filtering pathogens is essential if you visit high-risk areas. The filters are tested to meet NSF standards and remove 99.99% of bacteria and protozoa from your water. Pathogens that this system can remove include E.coli, salmonella, cholera, and many others.

What We Don't Like

It’s Fragile

Some customers who praise this filter also say that it is flimsy and comes apart relatively easily. The problem mainly affects the dirty water bag, which tears along the straps.

After complaining to the manufacturer, these users received replacements. This suggests that the issue affected a bad batch rather than being caused by a design flaw.

Filling Is Tricky

Pouring water into this system is easy, but filling it entirely is a different story. Some users say it is challenging to fill up. This isn’t a very common complaint, but it is something to keep in mind if you need to filter a lot of water.

Product Specs

Capacity 2 x 4 liters
Filtration rate 1.75 liters per minute

User Experience

I found this GravityWorks filter system to be quite remarkable. Having used it on several backpacking trips, this system has proven to be an effective and efficient means of acquiring clean water from various sources. It took a bit of time to master the backflushing technique, but once I did, I noticed a significant improvement in the filter's performance. I also appreciated the added enjoyment of watching water transition from the dirty bag to the clean one, an oddly satisfying process. Be aware, however, that the product's plastic components may initially impart a taste to the water, but this dissipates after a few uses.

LifeStraw Personal Water Filter

Most Durable Portable Water Filter

If you are without treated water for a while, you won’t want to waste time on maintaining your personal water filter. The LifeStraw filter is made to last, setting it apart from other straw filters. You will be able to filter a very impressive 4,000 liters of water before replacing the filter.

Made from eco-friendly BPA-free recyclable plastic, it uses a hollow fiber microfilter. The straw also includes a mouthpiece cap, bottom cap, and carry strap.

The straw filters 99.99% of bacteria, parasites, and microplastics. It is a great choice if you are heading to heavily polluted zones.

What We Like

Long Life

LifeStraw estimates that this filter will last up to five years if used correctly. You will save a great deal of time and money as it will require fewer replacements. This is particularly impressive as it can filter up to 4,000 liters of water — far more than its competitors.

Good Cause

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

These filters are environmentally friendly as they are made from recyclable plastic. It is a survival tool and a travel aid while also being kind to the planet.

Filters Plastic

One rare advantage is that this straw filters microplastics. This is unusual, even among portable water filters. It also filters almost 100% of bacteria and parasites.

What We Don't Like

It’s Tiring

Users praise this filter’s effectiveness, but some say it is hard work to draw water through it. Sipping requires physical effort and might be uncomfortable if you have never used a straw filter before. Some reviewers recommend this straw for emergencies rather than everyday filtration.

Limitations

The straw has a long lifespan and is an overall excellent filter, but it falls short in some areas. It doesn’t fit into water bottles easily, and there is no way to attach it to water bags or reservoirs.

Personal Perspective

I'm impressed by the functionality and purpose of this water filter. It's a vital tool in my emergency kit due to its lightweight and compact design, it even doubles as a handy gift for my active, hiking relatives. The company's charitable actions, funding potable water for children in need, adds a layer of nobility that truly resonates with me. However, the cost seems steep given it's mass-produced and made of simple, light materials. While it effectively filters water, even in risky conditions, the price point does raise eyebrows considering the competition. Despite this, I've used this water filter in various situations, from rivers to lakes, and it has never let me down.

Etekcity Water Filter Straw

Best Filtration

We didn’t expect to find a compact water filter straw with the same filtration power as larger units. This straw uses three-stage filtration for greater efficiency and safety. It is also 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 remove 99.99% of microbes, heavy metals, and chemicals.

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

What We Like

Long-Lasting

Each filter cleans as many as 1,500 liters before it needs replacing. This is an effective, convenient tool to take on extended trips, as maintenance shouldn’t be required. A backwash device is included for easier cleaning and to prevent clogs.

Triple Level Filtration

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

This is more important in high-risk areas where the extra layers of protection provide peace of mind.

Filters Almost Everything

There is very little that this straw can’t deal with. It filters out heavy metals, chlorine, volatile organic compounds (VOCs), debris, and pathogens. You will be protected against numerous bacteria and contaminants, and your water will be healthier as a result.

What We Don't Like

Difficult Suction

According to some buyers, sucking water through this straw is hard work. They were pleased with its effectiveness and noticed visible changes to their water quality, but still felt drinking through the straw was tiring.

Most users are still very satisfied with this filter, but it’s worth keeping in mind, particularly if you have breathing difficulties.

Hard to Fill

Some customers complained that filling the included water bag can be difficult. This won’t be an issue if you are drinking water directly via the straw, which can be done without the bag.

Product 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

Community Feedback

Excellent product for emergency situations! This emergency filter has been a comforting addition to my van's evacuation kit, and although I haven't had to use it yet, knowing it's there gives me peace of mind. In a world where water crises are becoming increasingly common, this filter is a boon, capable of transforming questionable water into a safe drink. The instructions are crystal clear, promising up to 395 gallons of clean water in an emergency, enough to sustain my family and friends for a month. This straw is for personal use, perfect for hiking, and it's even possible to use the bag to filter water into a cup for heating. However, it may not be ideal for group needs, so if you're planning for a larger crowd, opt for a larger filter.

Survivor Filter Pro Water Filter

Best for High-Risk Zones

You might have noticed that some of our favorites don’t filter viruses. This pump does, so it is an excellent choice if you travel to areas with a high exposure risk. The filter also tackles bacteria and heavy metals, so it is a well-rounded option.

Its materials are similar to those used in car manufacturing and Apollo space missions, so you can be confident that it is durable. The 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.

This Survivor product also includes a drinking cup, travel bag, user manual, and all necessary components and tubes.

What We Like

Filters Viruses

Most pumps can’t handle viruses or are limited in the contaminants they can filter out. This model removes heavy metals (including lead), bacteria, and viruses from your supply.

It’s Durable

If the materials are good enough for car manufacturers and astronauts, this filter is certainly built to last. In addition to its durability, it is also BPA-free and weighs less than a pound.

We were startled by this filter’s 100,000-liter lifespan. It goes without saying that this product will last a long time and is worth choosing for its durability alone.

Filters Lead

Lead is a highly dangerous contaminant and one that is difficult to filter out of water. Not all filtration systems are capable of removing it, so we are very pleased that this one does.

In addition to lead, it also purifies your water of most other contaminants and is one of the most thorough filters we have seen.

What We Don't Like

More Costly

Compared to filter straws, this filtration system isn’t cheap. Still, its price is not unreasonable when you consider how effective it is. The sophisticated filters and high-grade material contribute to the cost, so this isn’t a budget option.

Relatively Slow

You won’t have to wait a long time for this pump to work, but its filtration rate is relatively slow compared to some of the other products on our list.

The straws we chose are quicker as they filter water immediately as you drink it. In this case, you have to manually pump the filter and the filtering process itself is quite slow.

First-Hand Impression

Got this portable water filter for an overseas trip and it performed beyond my expectations. It's compact, lightweight, and can turn any dubious water source into clean, refreshing drinking water in just a few minutes. Just remember to dry it properly before packing it away and you'll have a trusty companion for any camping or trekking adventure.

Sawyer Water Filtration System

Best Portable Water Filter for Leisure Travel

If you want a portable filter for hobbies and activities, this filtration system will serve you well. Customers praise its convenience and say it is efficient and easy to use.

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

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

What We Like

Great Functionality

Buyers praise the ease of use of this filtration system, paying particular attention to its simplicity. Anything that makes it easier to access filtered water is positive and this is one of the most user-friendly models we have seen.

Filters Microplastics

If you are camping, hiking, or spending a few days off-grid, this filter will be more than sufficient. It removes almost 100% of bacteria and protozoa, and it clears all microplastics from your water. It is perfect for anyone who wants to travel off the beaten path while ensuring they still have a safe water supply.

Excellent Accessories

This product includes some of the best extras we have seen with a portable filter. Rather than focusing on extra bladders or straps, Sawyer included storage bags and cleaning gear. This makes maintenance easier and improves the overall durability of the filter. It could even eliminate the need for premature replacements.

What We Don't Like

Limited Filtration

Some customers mention problems with sediment and this filter won’t remove heavy metals, viruses, or chemicals from your water.

For this reason, we recommend only using this filter for camping and other outdoor activities, as it probably isn’t effective enough for use in high-risk zones.

User Experience

This portable filtration system has been a handy companion during my hobbies and activities. I've found it efficient and straightforward to use with its lightweight design and easy-to-use caps. The inclusion of a hollow fiber filter is impressive, eliminating almost all bacteria, protozoa, and even microplastics from my water. The additional cleaning plunger, coupling, and storage bag are thoughtful extras, although I've noticed the filtration can be somewhat limited.

Membrane Solutions Personal Water Filter Straw

Best Portable Water Filter for Sediment

This well-rounded filter can help you out in tough situations. The activated carbon four-stage purification system is effective against pollution, odor, chlorine, organic chemicals, and debris larger than 0.1 microns. It is a great piece of kit to have in case of an emergency and offers 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, and it provides a 450 mL per minute flow rate to ensure you receive water quickly.

What We Like

Cleans Sediment

The four-stage filtration system manages pollutants such as pollen, bacteria, algae, chlorine, and organic chemicals. The activated carbon filter (third stage) and hollow fiber ultrafiltration membranes (fourth stage) improve the taste and appearance of your water. This is an excellent filter for both recreation and emergencies.

Value for Money

Compared to some other portable water purification systems, this one is affordable without compromising on efficiency. It is a high-quality, effective product that won’t break the bank. We recommend it if you want a powerful water filter pump on a budget.

Lightweight Companion

Weighing less than a pound, this filter can be taken hiking or camping. Despite its small size and low weight, it doesn’t compromise on quality with its four-stage portable water filtration system.

What We Don't Like

Won’t Filter Viruses

The filter does a great job of filtering bacteria, but it won’t be able to remove viruses. This filtration system should be used for domestic adventures rather than overseas visits to high-risk areas.

Product Specs

Capacity Up to 1,500 liters per filter
Filtration rate 450 milliliters per minute

Personal Perspective

As an outdoor enthusiast, I found these Life Straws incredibly handy for hiking and camping, eliminating the need to lug around heavy water bottles. They're straightforward to use and conveniently small, fitting perfectly in my family's emergency bags. While the product itself is excellent, I felt a larger size would have increased its longevity. I've even integrated a couple into my personal go bag along with a cut-up t-shirt for filtering larger debris. Although I've yet to use them on my upcoming trip to Africa, I'm optimistic based on a relative's recommendation and my own experience so far.

LifeStraw Go Water Filter Bottle

Best for Daily Use

Are you looking for a filter that you can take anywhere you go? If so, this LifeStraw filter bottle could be the perfect solution. It filters out bacteria, parasites, chlorine, and other harmful chemicals such as pesticides.

It is designed to improve the taste, smell, and appearance of your water. The bottle is BPA-free and, as usual from LifeStraw, it is made of recyclable plastic. If you remove the filter, it is also dishwasher safe.

LifeStraw gives back by donating water to a child in need every time somebody buys a bottle.

What We Like

Filters Chemicals

This is a great filter for emergencies, but it is also excellent for everyday use. It filters chlorine and other chemicals such as pesticides and herbicides from your supply. You can use it to clean your tap water, so you always have healthy water available.

Easy Maintenance

Ultimately, this is still a water bottle, so maintenance is straightforward. Simply rinse it as you would any other bottle, or put it in your dishwasher (after removing the filter) if you want to save time. It’s made from BPA-free plastic, so it is reusable and will last you a long time.

Better Water

As it filters out chlorine and other chemical treatments, your water will taste and smell much better. If you want to stay hydrated without installing a large or expensive filtration unit, this is an excellent budget-friendly option.

What We Don't Like

Regular Maintenance Needed

If you use this bottle regularly, take extra care to maintain it. The filters need to be replaced frequently, and you will need to clean the bottle after every use. Remember, the bottle is dishwasher safe, so this shouldn’t be a problem if you have one.

Sipping Is Hard

Drinking water from this filter bottle isn’t as easy as it would be from an ordinary bottle, so you will need to expend some extra energy. For many people, this won’t be a problem, but it can be particularly difficult for people with breathing difficulties.

My experience with these water bottles has been a mixed bag. On one hand, they're great for ensuring clean, filtered water from any faucet, a feature that came in handy during my trip to Japan. However, the straw made it difficult to drink, especially when I was trying to take my supplements. The bottles proved less convenient in places where bottled water was readily available. Despite a few drawbacks, such as the lack of insulation causing the bottle to heat up quickly and the straw requiring a strong suck to work, I do appreciate the eco-friendly aspect of reducing single-use plastic bottles.

How Portable Water Filters Work

If you watch a lot of reality TV, you might have seen people learning how to survive in the wilderness using every available resource. Some scenarios involve drinking very unpleasant fluids, which is probably something you want to avoid on a long camping trip.

Portable water filters are designed for situations where you don’t have access to a treated water source. Whether you’re camping, hiking or your water supply has been interrupted, a portable filter is an important tool that could be the difference between life and death.

The Science of Water Filters

There are various ways to purify water but they each operate on the same principle: any molecules that don’t belong in pure water are contaminants. If contaminants can find their way into your water, they can also be forced out (1).

In this context, water purification is the process of chemically treating water to kill and remove pathogens and toxins, 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 usually follows purification because it can also remove the chemicals used during water treatment (3).

Water filters come in many shapes and sizes. Reverse osmosis filters push water back and forth through a membrane that traps contaminants. Activated carbon filters absorb impurities and only allow clean water through.

Whatever the engineering, the result is the same — cleaner water that is also safer to drink. Water filters can remove all sorts of impurities from chemical toxins to dirt and germs.

Types of Portable Water Filters

Much like stationary water filters, there are various types of portable water filters. All of them will provide you with cleaner water, but some types might be more suitable depending on their capacity, size, and user-friendliness.

Water bottle filters are the most convenient filters for travelers. All you need to do is add water and the bottle will take care of the rest. They are 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 the preferred option as they remove more pollutants.

Bottle filters are not perfect, however, and many models are unable to filter out certain chemicals. Most are ineffective at tackling fluoride, nitrates, and cadmium.

Pros

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

Cons

  • Limited chemical filtering
  • Maintenance required

Water Filter Straw

These function the same way as an ordinary straw: you simply place it in the water and sip. However, a water filter straw is larger and heavier to accommodate its filtration system. This means sipping will require a little more energy.

Water filter straws are very effective at trapping pathogens and debris. They also remove unpleasant tastes and odors from your water. These filters are very versatile, as you can use them with various drinking vessels and filter water immediately as you drink.

The main drawback is that they clog easily, which means they require frequent maintenance.

Pros

  • No need to add water
  • Affordable
  • Improves the taste and smell of water
  • Highly effective

Cons

  • High maintenance
  • Limited at filtering heavy metals and chlorine

Gravity Filters

A gravity filter is simpler but less convenient than other portable devices. It has two containers, one above the other, with a filter between them. Water is added to the top container, then drips down through the filter and into the bottom container, where it is dispensed.

Different systems use various types of filters, with ceramic and activated carbon among the most popular. They are both highly effective at removing the majority of contaminants.

Gravity filters are useful if you are camping or staying somewhere off-grid, but you need to set them up and give them time to work. They also occupy more space than other portable filters.

Pros

  • Durable
  • Filters most contaminants
  • Some maintenance is necessary

Cons

  • Must be assembled
  • Less compact than other portable filters

Water Filter Pumps

Pump filters — as they are sometimes known — aren’t much bigger than filter bottles or straws. They are small and light enough to fit inside your bag or backpack and require little effort to use. A tube is inserted into a water source, pumped through a filter, and then consumed via a tube-like straw.

Common water filter pumps use either fiber or ceramic filters. Neither type is able to remove all pathogens that might be in your water, so some manufacturers add an activated carbon filter.

These filters are highly effective and convenient, but keep in mind that you will need to pump water through them manually.

Pros

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

Cons

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

Other Portable Water Purification

We recommend the above four types as they are the most effective, easiest to use, and most portable. Some less popular alternatives include:

  • Chemical purification: Chemical tablets can be added to water to treat it as needed. This is an effective solution but introduces some chemicals that you might be uncomfortable drinking.
  • UV filters: These are bottle-like containers with a battery-operated light. Although they are very effective against biological contamination, they need to be charged before use.
  • Backpack filters: Backpack water filters are effective for disaster relief, but aren’t available from retailers and are difficult to acquire. As the objective is to have easy access to clean water, this isn’t a practical everyday solution.

Things to Consider (Buying Guide)

There are countless portable water filters available today, so it’s important to try to narrow down your search. Ask yourself the following questions to get a better idea of which filter type is right for you:

What Will You Use It For?

Where you intend to use your filter is very important because it determines what you will need to filter. If you’re out in the wilderness, bacteria and sediment will probably be your main threats. If you’re traveling abroad in populated areas, viruses are a likelier threat.

Ensure that any filter you choose is capable of removing the relevant pollutants from your water supply.

Fact

Nine out of the ten countries with the worst water quality are in Africa, South-East Asia, and the Middle East. 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 very important. If you are only going to spend a few days away from home, a filter that requires regular maintenance won’t be a problem. If you anticipate a long or unpredictable trip, it’s better to choose a filter that won’t require much maintenance during the duration.

For extended trips, gravity filters are recommended. They are the most durable type and will need far fewer replacements than other popular portable filters.

What Size and Speed?

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

The only exception is the gravity filter. They aren’t heavy but they have multiple components you will need to keep track of. If you lose any components, you won’t be able to use your filter.

Also, consider how quickly you will need clean water. During 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 you or hinder you? Gravity filters are very effective but require assembling. They aren’t the right choice if you need clean water as quickly as possible.

Despite their maintenance demands, straw filters are probably the best choice in difficult situations. One drawback is that you need to sip on them, and you can’t transport filtered water using one. Bottle filters are great if you want to carry water with you.

Before You Buy a Portable Water Filter

Portable water filters are inexpensive and are an important tool, whether for survival or simply for camping. There are no real drawbacks to getting one, especially if you are currently planning a trip or travel regularly.

Even so, there are some things that portable filters can’t help with. Understand their limits before you try to use one in the wrong situation.

  • They aren’t armor: If you are traveling to a high-risk area, remember that these filters won’t protect you against bugs or airborne pathogens. Make sure 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 are compact, but this can also work against you. You will need to make alternative plans to clean yourself, as these devices won’t provide enough water for a thorough wash.
  • Different water composition: Whichever filter you use and however effective it is, the water will likely taste different from what you’re used to. Many factors influence how water tastes. Don’t be surprised if the filtered water you drink in other countries tastes differently from how you expect (5).

Quick Tip

If possible, boiling water is a good way to purify it. In fact, distillers utilize this method. It isn’t very convenient but it can make a world of difference to your travels (6).
