We have learned and talked about water scarcity for decades now.

Most of the time, when we do so, we are talking about the shortage of pure, drinkable water, you know. And a survival adventure can show you how severe the issue has become.

In case you didn’t know, pollution has affected even the well-kept areas in the wilderness. It is not surprising, then, to see that you have problems finding pure water during survival runs and emergency bugout situations.

Even the most natural streams in the forest may have contaminants that can threaten your life and health. It is why people do not want to take risks.

This way, you can bring an empty water bottle and refill it with pure water whenever you want. Sounds incredible, right? Well, you must have a water filter most suitable for your survival adventure, though.

In this article, we have talked about five of the best survival water filters on the market. We have picked the products based on their performance, cleaning options, and ease of use. We believe you can make the best pick based on your specific needs.

Survivor Filter Pro Hand Pump Water Filter

Survivor Filter Pro Hand Pump Water Filter Review

  • Type: Hand Pump
  • Volume: Not Applicable
  • Flow Rate: 17 Ounces per minute
  • Capacity: 100,000 liters

Survivor Filter Pro Hand Pump Water Filter is undoubtedly the best water filter that any survivalist must pick from the market. It comes from one of the most trusted brands in the category and can remove an immense variety of pollutants from natural water sources.

We should also appreciate the filter’, making it usable under any circumstances. It is also worth noting that Survivor Filter has included many innovative features in this small-looking package.


  • The Survivor Filter Pro Hand Pump Water Filter comes with an elementary-style use system. The filter comes with two hoses: the water inlet hose and the outlet hose. You can put the outlet hose into any form of water and the inlet hose to the container. You can get ultra-pure water in the container. As you can see, the process is simple that a toddler could do it.
  • The filter used in the package effectively removes viruses, bacteria, and parasites. Besides, the company’s independent testing revealed that the filter reduces the presence of heavy metals, odors, and unpleasant tastes as well. As for the technicalities, the filter does not let anything more significant than 0.2 microns through the system, meaning that you get rid of most contaminants.
  • Despite the affordable price tag it bears, the Survivor Filter Pro Hand Pump Water Filter has used exceptionally vital construction material. The shell uses ABS material, and Food-grade Activated Carbon is found in many components. Finally, the manufacturer has used medical-grade Polysulfone to make the filter.
  • We must also note that the portable water filter system provides one of the best flow rates you can find in the market. You can filter up to 17 ounces of water per minute, which is excellent. It means you can fill a comparatively large container or water in a few minutes. This filter system can help you stay worry-less about water in the long run.
  • Independent testing of the filter system also reveals that the filter can remove threats like Phi-X174 and E.coli from natural water sources. It is powerful-enough performance to recommend the system to most survivalists and hikers. Even if you are into long-term prepping, this filter will not let you down.


  • Some customers have noted that the Survivor Filter Pro Hand Pump Water Filter is not ideal for big groups. While solo survivalists can get enough water via a few minutes of pumping, filling too many water containers is too much effort. Therefore, we cannot recommend this water filter for big groups, especially if you have varying needs.

Extra Features

  • It may not be an extra feature, per se, but you can connect the Survivor Filter Pro Hand Pump Water Filter to several accessories. Considering that a single filter unit can filter up to 100,000 liters of water, buying one of those accessories is a great decision. For instance, you can use the collapsible canteens to store the filtered water you get from the filtration system.
  • The three-stage filtration system on this product is just off the charts from a performance perspective. It is also one of the most celebrated water filters on the market. Given that the filter works well with extreme conditions, you can expect a stable performance when you are in the wild for a casual survival adventure.

Buying Advice

For most solo travelers and small families, the Survivor Filter Pro Hand Pump Water Filter is the perfect water filter for survival adventures. It is an excellent addition to any prepping kit out there as well. The makers behind the product have combined the ideal performance with an ergonomic design and capacity. Although it does not have many convenient options like sip-to-filter, the design is suitable for entry-level survivalists and veterans alike. We cannot recommend the water filter for larger groups despite all these.

Katadyn Vario Water Filter

Katadyn Vario Water Filter Review

  • Type: Turn-to-filter system
  • Volume: Not Applicable
  • Flow Rate: 2 liters per minute
  • Capacity: Up to 1875 liters

One problem with our top pick is that it cannot filter a lot of water per minute. However, the Katadyn Vario Water Filter fixes this problem and introduces an innovative design.

The design makes the water filter an impressive choice for larger groups and families. You will not have any trouble connecting it to a variety of containers, either. This is also a survival water filter popular among survivalist veterans.


  • Compared to our top pick, the Katadyn Vario Water Filter does not require too much effort from the customer. The turn-to-filter system is less time-consuming as well. Therefore, when you want to get an entire container of pure water quickly, you can count on this water filter without a doubt. Its core handle has also been designed for maximum durability.
  • While the company does not specify what the filter can remove, the included filtration layers are very effective. The Vario Dual Technology uses two layers: a high-performance glass fiber filter and a pre-filter made of ceramic. Depending on the situation you are in and the type of water source, you can shift between these two options.
  • It is impressive that the Katadyn Vario Water Filter uses a replaceable carbon core. This core can filter up to 1875 liters, which is significant. When it comes to removing pollutants, the carbon core can efficiently deal with chemicals, toxins, odors, and other elements that make water impure. The ceramic pre-filter is easily-cleanable as well.
  • The Katadyn Vario Water Filter has one of the best flow rates you can expect from a portable water filter. The system can filter up to 2 liters of water per minute. It means you will not need more than a few minutes to fill an enormous water container. It is also why we recommend it to large groups of survivalists.
  • As you can guess, you will not have any trouble using the water filter for heavy-duty needs. The bigger size of the system makes it more suitable for more extensive water sources. You can keep using the filter without worries of losing it somewhere. We should also appreciate the overall build quality of the water filtration system.


  • While the more prominent design is great for usability, it poses another problem: space consumption. You will have to dedicate a lot of space from your bugout bag or backpack if you want to carry this water filter around. Again, it is not a problem when traveling in a group. For solo survivalists, the filter is a little too big.
  • We noticed that the Katadyn Vario Water Filter does not show any independent cleaning statistics as to what it can remove. We would have loved to see a better, more scientific answer from the makers instead of saying that the filter can remove toxins and chemicals. By the way, replacement cartridges for the machine are relatively more expensive.

Extra Features

  • Like Survival Pro, Katadyn is a fully-fledged company in water filter equipment. So, it is easy for you to connect the water filter module to various accessories. Even though additions and replacements for the product are expensive, you can find them in online stores and typical stores across the country.
  • Conveniently, the Katadyn Vario Water Filter comes as a complete package. You can find the pre-filter, carry bag, and cleaning pad in the box. You can use the carry bag to take around almost everything you need for filtering out water. If you have gotten started with survivalism and prepping, this nudge can save you time and space.

Buying Advice

For one, the Katadyn Vario Water Filter is an excellent choice for survivalists traveling in groups and those who need a lot of water. This product is expensive compared to our top pick but comes with a more innovative cleaning design.

In the end, you will not have any trouble using the water filter with water sources that you have never seen before. You must be ready to dedicate more space for carrying around the filtration system.

LifeStraw Personal Water Filter

LifeStraw Personal Water Filter Review

  • Type: Sip-to-filter
  • Volume: Not Applicable
  • Flow Rate: Not Specified
  • Capacity: 4,000 liters

There are times when you care more about filtration quality than convenience. If you need such an essential water filter, the LifeStraw Personal Water Filter is a great pick. It comes with a compact design but gets the job done most of the time.

Despite all of these, the water filter can filter a good amount of polluted water. You can also count on the seemingly weird but effective filtering mechanism in most survivalist circumstances.


  • The LifeStraw Personal Water Filter is very portable and does not take much space from your bugout bag or the survivalist backpack. Because of the no-fuzz design, you can use the filter system with any water source. Rest assured, the product will ensure good results, turning impure water into something drinkable.
  • A single LifeStraw Personal Water Filter can filter up to 4,000 liters of water. This number is not only impressive but very practical. You can throw this filter into your bag, and you can stop worrying about drinking water for a couple of survivalist trips in the future. It is also significant that the filter removes almost every type of pollutant from water.
  • The brand claims that the portable water filter can remove99.9999% of bacterial, protozoan parasites, and other risks. The filter has a pore size of 0.2 microns, meaning that not many pollutants make it to your mouth. Because you can sip the water to filter it, you can increase this filter’s flow rate by a long shot.


  • While the LifeStraw Personal Water Filter is a compelling piece of tech, it provides zero to minimum convenience. Many people, especially kids, may have trouble using the water filter with unfamiliar water sources in the long run. Because of the sip-to-filter design, you cannot use the device for water storage purposes, either.

Extra Features

The LifeStraw Personal Water Filter does not have any extra features inside. However, you can get multiple-unit packs of this device for reasonable prices.

Buying Advice

You have to make a few compromises when choosing the LifeStraw Personal Water Filter over one of the typical water filters we saw above. However, you can embrace a more compact way to filter water while doing so.

Sure, the company has to work on the flow rate and the overall capacity of the smart straw, but that is it. If you can live with these disadvantages, you should consider getting this filter.

Sawyer MINI Water Filtration System

Sawyer MINI Water Filtration System Review

  • Type: Squeeze-to-filter
  • Volume: 16 ounces
  • Flow Rate: Not Specified
  • Capacity: 100,000 gallons

If you think our first alternative was a little too inconvenient, you should check out the Sawyer MINI Water Filtration System. This water filter employs a more modern method to purify water.

However, it does not store the water anywhere. You have to filter water as you need it. If you are okay with that limitation, you should keep a lookout for this product. In the end, you will not regret adding this compact thing to your bag or survival backpack.


  • The Sawyer MINI Water Filtration System uses a squeeze-to-filter system that is incredibly effective. It means you can connect one end of the filter to a water container and squeeze the container to push water through the filter. And you can enjoy high-quality water on the other end of the filter, a pretty convenient way.
  • The included filter has a pore size of just 0.1 microns. The number translates to the filter clearing out various pollutants from the water source. For instance, it can remove almost all bacteria, such as E.coli and cholera. The filter is very effective when it comes to eliminating microplastics from water.
  • Compared to other water filters in this category, the Sawyer MINI Water Filtration System packs an incredible filtration capacity as well. A single cartridge can filter up to 100,000 gallons of water, and you can use the 16-ounce squeeze pouch to store water. The drinking straw also comes in handy at times.


  • While the design is more convenient than the previous pick, the Sawyer MINI Water Filtration System offers a better place to store water. However, you cannot use this filter for your long-haul water filter needs or living in a group.

Extra Features

There are not many additional features in the Sawyer MINI Water Filtration System.

Buying Advice

On the one hand, the Sawyer MINI Water Filtration System is a definite convenience upgrade. Still, you cannot use the system to pour water into a big container and store it.

However, as a hiker or survivor, you may have to carry at least some water at a shorter distance. In those instances, you can consider this compact package from Sawyer.

Seychelle Advanced Water Filter Bottle

Sawyer MINI Water Filtration System Review

  • Type: Sip-to-filter
  • Volume: 28 ounces
  • Flow Rate: Not Specified
  • Capacity: 100 gallons

If you are looking for the most convenient way to filter water during emergencies, you should consider the Seychelle Advanced Water Filter Bottle. This is a fully-fledged water bottle that can purify water as you need it.

The sip-to-filter mechanism is more effective than you think, but you have to get used to applying more force during the process. In the end, carrying this water filter bottle does not consume a lot of space from your backpack, either.


  • You can get used to the sip-to-filter system without any prior experience. Once you have filled water from the source, you can sip up to purify water. Depending on the pressure you apply, you can get a good amount of water. You will love this kind of freedom if you spend most of your day moving across the forest.
  • For a bottle that you would carry around during the trip, the capacity of 100 gallons is excellent for the Seychelle Advanced Water Filter Bottle. You will have enough water to drink and days to spend before you have to replace the cartridge. On that note, we should mention that the cartridges are straightforward to find.
  • Even though the design is simple, the Seychelle Advanced Water Filter Bottle can remove radiological contaminants, heavy metals, and industrial contaminants from the raw water. So, even if you get into uncharted territories, this water filter will provide you endless water supply. We think you will value this assurance as a survivalist.


  • Squeezing the bottle to get water may work, but it is not ideal. Therefore, you need something other than Seychelle Advanced Water Filter Bottle to enable water storage. In short, the bottle is made for personal use only.

Extra Features

The Seychelle Advanced Water Filter Bottle does not offer any extra features.

Buying Advice

If you need a super-convenient way to hold water and purify it during emergencies, we think you can choose the Seychelle Advanced Water Filter Bottle. As a survival water filter system, it is pretty effective and does a great job of removing even radiological contaminants. It is also impressive that the bottle does not cost as much as the other options.
