Nature has provided us plenty of water sources. There are lakes, streams and small rivers that we can use to take a bath in or for cleaning our clothes. As for drinking it, one should not do so unless he or she has a quality water filter handy. This is especially important as your life will depend on just one sip of unclean water.

Lakes, rivers and streams were once the main source of drinking water. But this is no longer the case, as numerous factories and companies have now polluted the once potable sources. A single drop of water can contain billions of harmful bacteria, viruses and dangerous chemicals, all of which can prove to be fatal for humans.

Whether for camping, hiking, mountaineering or for surviving, a reliable source of drinking water ensures you’ll live for another day. For this reason you’ll need a good water filtration system for the job!

Remember the rule of drinking water in the wild- Filter First, Then Hydrate.

 

 

A. What Is A Survival Water Filter?

What’s the first thing that comes to mind when you mention the words “water filter”?

Many of us would think either the big stainless steel tanks connected to the kitchen faucet or the small filters that are independently attached.

A survival water filter works the same way, with the exception of being portable. It’s one of the list of essential items to get if you’re making a bug out bag. Survival water filters are great for staying alive and preventing death due to dehydration.

The best survival water filters are ones that can effectively filter out harmful contaminants that could make you very sick very quickly. Almost all of us would think twice about taking a gulp of water from lakes because we know that we can get ill from it. Some of the worst things that can happen are diarrhea, vomiting, gastroenteritis, etc. But if you have a filtration system, you’d be more confident that you can quench your thirst without getting sick.

Not to mention filters can also make water smell better and taste better as well.

Why Is It Important To Own A Survival Water Filter?

You will need an excellent survival water filter to be able to drink from any stream, lake or river anytime when needed.

Water filters can get you clean, drinkable water with little exertion, i.e., squeezing or pumping water through the filter. They are also effective and very convenient to have along. These equipment shine best in emergency and survival situations where there will be very little water to drink. These filters will save your life while you’re waiting for rescue or until you reach the next stop.

Potable water isn’t just for drinking. You can use it to cook your food and for sanitation purposes. In order to survive, each person must have at least a gallon of water per day. Unsafe water will just bring about more trouble as they can enter your system through various means.

B. The Buyer’s Guide In Finding The Best Survival Water Filter

There’s more to a survival water filter than meets the eye. Aside from being able to effectively filter water, there are features that you’ll need to consider.

1. Portability

The ultimate water filtration system should be portable enough that you can bring it everywhere you go, regardless of your clothes and your bag. Today’s portable water filters are small and affordable that there’s absolutely no reason why you shouldn’t have one in your hiking or emergency bag.

All the essential survival tools should be able to fit inside your bug out bag. This bag should always be ready in case of emergency situations. Some water filters are so small that they can easily fit in your pocket. Some just weigh as little as 2 ounces. A good portable filter will be anywhere between 6 to 13 inches.

2. Filtration and Purification

Purifying water is not an absolute necessity if you’re hiking within the US. If you intend to go on trips in other countries though, this feature becomes a must-have.

  • Water Filtration

Filtration is done by passing the raw water through a filtration sieve, via biological or by using chemical processes. One of the most common filtration methods is by passing the raw water through a carbon filter to make it safe to drink. It should be noted that this filtration method will not eliminate certain viruses or certain chemicals in the water. Water filtration does not ensure that the water is 100% safe to drink.

  • Water Purification

Purification is done to eliminate impurities from the raw water. While filtration deals with cleaning the water, purification makes the raw water free from chemicals, pathogens and possible bio contaminants. Boiling is an example of a purification method. In the same vein as filtration, purification may not eliminate other types of impurities in the water.

 

3. Filtration Effectiveness

Just how fine are the sieves that are used to filter the water? It all boils down to the micron level. The general rule is that a smaller micron level is better at filtering out contaminants than filters that have bigger micron levels. There are some survival water filters that are advertised to have .1 or .2 microns, while others say they can eliminate 99.9% viruses and microorganisms.

4. Understanding the Micron Rating

What is a micron rating? Essentially, it measures the size of openings found in a filter. The smallest micron sizes are at .1 microns, which can stop bacteria from passing through (bacteria is at .2 micron). A filter that has a smaller micron rating should also be able to prevent cysts and viruses from passing through. Pore size helps if you plan on drawing water to drink from springs, rivers and deep wells.

5. Output Speed

How much water can a filter process at one time? A high flow rate makes it easier and quicker to collect potable water from a source. In general, larger filters will have a higher speed of water output as compared to the smaller water filter variants. Pump type water filters can put out a rate at around 1 to 2 liters of potable water per minute. Straw-type water filters have smaller filters, but they are more portable and it can be used to drink water directly from the souce. The “sip and drink” mechanism is only possible because of the filter’s reduced surface area.

6. Convenience

How easy is it to draw and drink water using the filter? Each type has its own pros and cons. For example, the straw type requires you to submerge the device and suck the water straight from the source, while the pump type requires a bit of exertion to use.

7. Taste Quality

Great-tasting water is free of chemicals and microorganisms. The moment we taste something funny in the water, we immediately stop because it is our natural instinct. Potable water should be at best neutral. Water filters will sometimes have features such as activated carbon that effectively traps the “funny taste” of contaminated water.

8. Passes EPA Standards

Make sure to check out if a water filtration system passes EPA standards. The Environmental Protection Agency has set a standard that determines whether water is safe for public consumption or not. In short, if a water filter passes this, then it should be safe for you to use.

B. Types of Water Filters

There are now different water filters, each with their own unique mechanisms. Here’s how each type works in terms of filtering and drawing water from the source, along with the best of its kind:

1. Pump Type Filters

Raw water is “pushed” via a pump mechanism through the filter. This type of water filter usually have the fastest flow rate as compared to the other water filter types. A good pump type filtration system can usually put out a liter or two of potable water per minute. You get more potable water in less time which can come in handy in some emergency situations.  A .2 micron glass fiber filter pushes out drinkable water quickly with little to no effort. You also get a durable 11-oz microfilter which attaches to your hydration pack of water bottles and 1/4″ drink tubes.

 

 

2. Straw Type Filters

Just as the name says, straw types are basically straws that can filter water while you take a sip. The advantages are many- you carry around a lightweight and extremely portable straw in your pocket or your backpack and whip it out as needed. You will have the ability to drink straight from the source or collect raw water in a container and use the straw on it. On the other hand, you’ll have to be right beside the water source if you don’t have a container you can use to collect the raw water. Older people will probably find it more difficult to use a straw type water filter as they will have to be on all fours to get a good drink.

 

 

LifeStraw Water Filters will let you drink up to a thousand liters of water without common water contaminants such as chlorine and iodine. The compact size and the negligible weight (only 2 oz) make it the perfect companion for camping and hiking purposes. Simply submerge the LifeStraw in a nearby pool of water and take a sip. You won’t have to wait for the chemicals to react or pump water when you have the LifeStraw packed.

Life Defender’s excellent .01 micron filters can be used reliably to a maximum 1,500 liters of water before needing a replacement. The accompanying 22 oz water bottle holds the taste-free, contaminant-free water as it passes through the coconut activated carbon filter. The BPA aspect makes the bottle forever reusable.

 

4. Ceramic Type Water Filters

Ceramic water filters are among the most popular portable water filtration systems for a good reason. Ceramic has been mainly used to filter out contaminants since ancient times. This material is very good at producing very clean, drinkable water from lakes, rivers and ponds. Though they may appear to be solid, a ceramic is actually porous and has many microscopic openings that can weed out microbes and harmful contaminants.

With all that good, why aren’t all water filters made of ceramic? One of the main disadvantages of ceramic is that it’s heavier and more fragile. You can’t just leave them along with your other things or they may break prematurely. If you don’t mind the extra weight, ceramic filters are among the best when filtering out bacteria and other contaminants from outdoor water sources. Ceramics last for a lifetime and they bring danger down to almost zero when you use them.

 

 

The special Vario Dual technology brings a unique aspect to the water filtration system. The whole Vario tech has 3 stages of filtration- an adjustable pre-filter made of ceramic which can be changed according to how cloudy the raw water looks, active charcoal to eliminate the taste in water, and a high performance glass fiber filter to make the water safe to drink. The ceramic disc is cleanable, which considerably extends the lifespan of the Vario-based water filter. The .2 micron glass fiber microfilter is great for eliminating harmful water-borne bacteria. The carbon core is replaceable, which overall makes the Vario Water Filter a good buy.

 

5. Gravity Water Filters

There’s no effort needed when you opt in for a gravity water filter. Basically, raw water passes through the filter and comes out clean and drinkable. The process goes like this- water is put on the container, which passes the filter as it naturally gravitates downward. The hose has hollow membranes that filter the water, making it safe to drink. Gravity water filters have the edge over pressure-based filters as they are more effective in producing potable water. The only disadvantage is that it takes a long time for the filtering process to be completed. It’s not recommended if you’re on the go and need a quick drink ASAP!

 

The huge 25 liter reservoir will satisfy your group’s need to drink water during camping trips, hiking and in emergency situations. The Xpor Outdoor Hydration Pack is perfect for small groups of campers and outdoor adventurers. The food grade TPU material holds the potable water in place. There’s even a versatile shower head included.

 

Skip the effort of having to pump potable water with the Platypus 4L Water Filter System. The gravity-fed filter takes the raw water from the dirty reservoir and proceeds to produce safe drinking water while it hangs from a support. Platypus’ offering filters water an a rate of 1.75 L per minute. The filter can be used to produce 1,500 L of water before needing a replacement. This is one of the best water filters to get if you’re planning to have a filtration system for the whole group or family.

 

Sawyer products are known for their efficiency and technologically advanced solutions that produces drinkable water better than most US standard bottled water. The SP194 is no exception- the filter eliminates viruses clean off while churning out up to 4 L of safe water within a record 10 minutes. It’s great for solo use, but it shines when used in a group setting. The gravity filtration system simply requires you to hang the bag up to filter the raw water inside the reservoir. Just fill it up, attach the filter and tubing to the “clean” tank reservoir, and you’ll have safe water to drink within minutes.

 

The LifeStraw mission comes with all the bells and whistles from a premium water filter system. The high capacity reservoir can be filled up to a maximum of 12 or 5 L. The filter sports a hollow membrane and can be easily hooked up to a tree or any similar support. Expect an 18,000 L filter lifespan that churns out potable water at a rate of around 9 to 12 L drinking water per hour.

The best water filtration system is the one that specifically caters to all your needs, whether you need a simple filter system on short camping trips or a high-end water filter system for the whole family. It all boils down to preference. A straw water filter works best on solo hikes because of its unbeatable portability, while a gravity water filter system is best for group camping or for large-scale emergency situations.
