Things to consider before buying

The quality of a survival straw is a very important thing to consider. If you purchase the wrong survival straw and drink water that has not been properly filtered, you may end up contracting a dangerous disease. The things you need to consider before you decide which survival straw is perfect for the job are the following.

Power Source

The best water filters don’t require any special equipment to function. That is why survival straw filters are such a good choice when traveling or camping. They don’t require charging at a power point or special batteries. They can be used straight after opening and you don’t have to be worried about having access to electricity or having any batteries in your pack. As long as you have a straw filter with you, you will be able to filter the water through your straw straight away.

Filtration System

A good water filter will not rely on chemicals to filter the water. The water is filtered directly through the fibers in the straw and so avoids possible ingestion of chemicals that are harmful to you. When drinking from dirty water, all the dirt, germs and bacteria become trapped in the filter, ensuring only good, fresh water is ingested. No chemicals means the water tastes clean and there is no unpleasant residue.

Best straw filter

Filter straws are made of a simple filtration design with no moving parts. This makes it efficient and less likely to break at a critical moment. It also makes them simple to use. By just placing them in the water and using them as you would any other straw makes, it’s easy for both inexperienced and experienced travelers, hikers and trekkers to use.

A scrubbing and filtration system in each survival straw ensures you can get fresh water straight away from any source. Dangerous illnesses and diseases can be found in stagnant or dirty water supplies. These can make the drinker violently ill and in some cases, can cause death. The germs and bacteria are trapped within the filter giving you the freshest drinking water possible.

A carbon filter within your survival straw is an added bonus which ensures that the water is not only good to drink but tastes fresh as well. Different contaminants in water may have a strong chlorine or musty taste, which can be unpleasant and difficult to drink. A carbon capsule blocks any vegetation or chemicals that can cause these bad tastes and allows you to enjoy your cool drink and rehydrate, so you can be ready for the next part of your hike.


Trying to carry heavy pieces of equipment slows momentum and drains your energy faster. On a long hike or when you are in the wilderness, you need items that can easily be carried. Survival straw filters are light weight and are easily handled.

Most filter straws are small enough to be kept in your pocket, meaning they can easily be accessed when you need them. It means there will always be space to bring along this possibly lifesaving tool, stored away in your backpack or carried on your person.

Filter Capacity

Filter capacity is the amount of times you can use the straw before the filter is no longer effective. Having a large filter capacity means you don’t have to worry about a straw not functioning properly when you need it, especially if you are in a situation where you have an extended need for fresh water and you don’t have access to modern plumbing.

Straw filters can be very economical. They require very little upkeep or intervention to keep it working properly, and one straw will easily cleanse up to 20 gallons of water. This would be roughly up to 320 cups of water before a replacement straw would be needed.


The most important job of your straw filter is to prevent germs and bacteria getting through. Most straws promise a 99.9999 percent rate of filtering out these contaminants and preventing you from becoming sick. There are many sickness and diseases which can be found in water. One common example, E.coli is caused by contamination of water by human fecal matter. It can cause cramping, diarrhea, vomiting and fever.

Anti-bacterial straw filter

Diarrhea is a gut infection which attacks the bowels and cause liquid and frequent fecal movements. Symptoms can include cramps, nausea, weight loss and a constant need to go to the toilet. Another dangerous example is dysentery. Dysentery is an inflammation of the gut which causes extreme diarrhea which results in bloody stools. Dysentery also includes vomiting, nausea and a high fever and is very contagious.

Bacteria in the water can even attack your organs. Hepatitis attacks the functioning of the liver and causes swelling and pain. A liver is the important part of the body’s process of removing toxins that are harmful to your health. The impact on the liver can cause pain, fever, tiredness, bruising, joint pain and swelling.

Parasitic infection also attacks the gut, causing vomiting and diarrhea. They are spread through fecal matter in the water, and contracted through swallowing or drinking the contaminated water.

The impact of these symptoms on your body is definitely not ideal when it comes to survival. It may cause dehydration, tiredness and inability to continue on your trip. That is why a straw filter is an extremely valuable part of any travelers or survivalists kit.   

Extra Features

Some water filters come with a water canteen which provides a place to store water. This gives you the ability to carry water with you, which is an advantage when you don’t know when you will next have access to water. This gives you the ability to use the straw with the canteen and ensures you always have a supply of safe drinking water with you.

Wrap Up

Water straws are a vital piece of equipment that you should not forget to purchase for your camping and outdoors activities. If there is a natural disaster, fresh water can quickly be tainted and a water straw in your preparedness kit means you can have fresh water no matter what your circumstances are.

Survival straws are also important for outdoor enthusiasts. No one wants to be caught unprepared in the wilderness. That’s why you need to always carry a survival straw with you on your trips. Lack of clean water is a traveler’s worst enemy.

By carrying a survival straw with you, you’ve at least got that front covered so you can focus on other things during an emergency.

The above candidates could easily be the best survival straw on the market. What are your experiences? Please share in the comments below.

4 thoughts on “Best Survival Straw Filter on the Market: Converting Contaminated Water”

  1. The Aquamira Water Filter is great as you can drink from a mud puddle and it still taste clean. One time, I was camping and it started raining so I threw up the poncho and put my metal cup out to collect water (I like to use as much water from the environment as possible). The pigment from the poncho came off and the water tasted like smoke (the poncho collected the smell). I tasted the water pre filter and it was foul, undrinkable; but with the filter it was clean and cold.

  2. Wow, that’s great to hear! Nothing like clean and potable water to drink especially when you’re thirsty and tired. I have my trusty LifeStraw since I remember. I thinks it’s one of the firsts handy water filter to come out in the market. I’m really dumbfounded on how science and technology have made our lives easier and safer. These are great products – don’t leave home without these inside your bag.

  3. It was about a year ago when I first saw this Sawyer mini from a hiking buddy. At that time, I was using an MSR Guardian purifier which was actually quite heavy, so I bought the same brand as hers. It was definitely worth trying. It was so lightweight and inexpensive, plus it is easy to drink from. The only thing I don’t like is that it cannot treat large quantities of water well. I drink water a lot so it was kind of a disappointment. Nevertheless, I’m still using it in some places where I can’t bring my vehicle.

  4. Hi Alex! If you want something that can purify a lot of water – say a thousand liters, then your best bet is the Lifestraw. I’ve been using this award winning straw and man, this straw is excellent! Don’t take my word for it – buy it and see!
