Best Survival Water Filter

by | May 27, 2017 | Reviews

If water wasn’t so heavy and tough to lug around, we would all just carry an unlimited supply with us while camping. We don’t need to tell you how crucial water is for survival, and how terrifying it can be as your supply starts to dwindle while you’re out in the middle of nowhere. As the sun gets hotter, anxiety levels rise, but there is a type of product that’s been gaining more and more popularity lately.

A survival water filter can save your life, save you from dehydration, or at the very least it can give you a little more peace of mind when your water supply isn’t exactly where you’d like it to be. Now, first and foremost, before we even start talking about choosing the best survival water filter, it’s imperative that you bring enough water with you in the first place. But even if you think you are already doing that, it’s a good idea to have one of these water filter straws none the less.

There are more and more to choose from all the time, so we’ve narrowed it down to some of the absolute best choices. They’re all relatively affordable, when you consider the alternative options, so we’ve chosen these straws based on their quality, performance, and also taken reviews into consideration because if most people report a great experience with it, that counts for something.

The Best Survival Water of 2017!

1. Lifestraw

Award Winning

Our Rating:  4.7 Stars (4.7/5)
No Chemicals or Batteries  
Filter Micron Size  0.2 Micron
Maximum Usage  Up to 264 Gallons

As far as something affordable goes, the LifeStraw is very reasonably priced, and great for what it is. It’s basically a thick straw, and it allows you to drink from water sources that you wouldn’t normally consider drinking from. You don’t need to boil the water first; you can drink it right out of the source.

LifeStraw is probably the most popular brand in this category, and perhaps the most accessible, but we’re going to be taking a look at some other options as well. For example, if you don’t mind spending more money, you can get some pretty neat survival filters. We’ll get to that in a moment. First, here’s a great variation on the LifeStraw, which is particularly useful if you’ll be needing to quench your thirst but won’t be able to stay near the water supply.

2. Lifestraw Water Bottle

BPA Free

Our Rating: 4.1 Stars (4.1/5)
No Chemicals or Batteries  
Filter Micron Size  0.2 Micron
Maximum Usage  264 Gallons

It’s basically a water bottle with a LifeStraw inside. You can fill it up and take the water with you, without having to stay right at the source. This can be useful in survival situations, or just a slightly more practical option. Instead of bending down and sipping right from a lake, you can just fill up the bottle and filter it as you sip.

There’s a gap between the bottom of the filter and the bottom of the bottle, which allows any dirt or sediment to settle at the bottom of the water bottle, so it doesn’t gunk up your filter and shorten its lifespan. This bottle is great for hiking, camping, backpacking… Everybody that owns it and understands what it’s for seems to love it. Some complains have been a chemical-y taste, but that isn’t a universal experience and ringing it out and letting it soak for a bit before your first use should help a great deal.

However, a major downside is that you’re still limited by how much water you can fit in the bottle, especially with the larger filter taking up a lot of that space, and we prefer to have our water filtered before we’re ready to drink it, so it’s good to go right away. It just feels better to be carrying around a supple of already filtered water, rather than carrying around unfiltered water.

3. Katadyn Vario

Waterbottle Base Adapter

Our Rating: 4.4 Stars (4.4/5)
Micron Size  0.2 Micron
Maximum Usage  500 Gallons per filter
Weight  1.45 lbs

This is a very cool device that accomplishes a similar goal as the LifeStraw Go, but does it in a much slicker way. Instead of filling up a water bottle and filtering it as you sip, the Katadyn Vario allows you to pump water from your water source, and filters it before it even gets inside of the bottle, so you could fill up multiple bottles at once.

Also, without a big straw inside your water bottle, you can carry more clean water. There’s just something appealing about being able to drink your already-filtered water normally, as opposed to having to suck it through a straw. Drinking through a LifeStraw is tougher than drinking through a normal straw, and sometimes when you’re thirsty enough you just want to chug it.

Now, it’s a bit more than double the price, but when push comes to shove it’s worth it. If you want to bring two bottles worth of water with you using the LifeStraw Go, you’ll need to buy two of them. With the Katadyn, however, you can fill up as many bottles as you want.

Addon: Survival Water Bags

If you opt for something like the Katadyn Vario, and don’t want to haul around extra water bottles, take a look at these water bags. They weight next to nothing and take up practically no space until you need to use them. They’re sterile, and you can filter water directly from your survival filter right into these bags.

4. Aquamira Frontier

Miraguard Technology

Our Rating: 4.4 Stars (4.4/5)
Origin  USA
Dimensions 8 x 4 x 2 inches
Maximum Usage  30 Gallons

If you just want something cheap and simple, here you go. It’s similar to the original LifeStraw that we featured first, so cons include the fact that it’s basically “on-demand”. You filter the water directly from the source and drink it immediately, rather than being able to have clear water when you aren’t right next to whatever your water source may be.

As you can see, there are a few different styles. We prefer the Katadyn because it gives you a lot more options. You can fill up while you’re at a source, and then take the water with you, and you aren’t limited by the size of your single bottle. It costs more, but when it comes to clean water – that’s a price we’re more than willing to pay.
