When out in the wilderness, water is one of your most important resources.

The problem is, carrying enough to meet your daily hydration needs will take up a considerable chunk of your very limited backpack space.

What’s more, you also need to make sure you can actually carry it across varying terrains and for long distances.

Planning your route ahead of time will allow you to reduce your load a significant amount by limiting your water supply.

What you can do instead is to supplement that limited supply with the best survival water filter.

LoGest Water Filter Straw, 2-Pack




Check Price

This first option comes from LoGest and is sold in packs of two water filters.

Like the first one, it is also compact and easy to bring on outdoors trips, measuring in at only 7.5 inches by 1.35 inches.

Product Highlights

When looking for the best water filter for survival, you can’t go wrong with LoGest.

In particular, you will love the small and compact size of this two-pack water-filtration device.

It can fit in a small pocket in your backpack or even carried using its built-in carry strap.

Despite its size, you can expect it to filter out 99 percent of bacterial and harmful contaminants from natural water sources.

Clean drinking water is your best hope during survival situations, but it’s not practical to carry around bottles after bottles of it.

Going this route also means you will run out of supply eventually.

This is where this LoGest Water Filter Straw comes in.

Not only does it guarantee access to safe drinking water, but it also frees up space in your backpack and makes your overall load lighter.

Impressively enough, this filter has a 1,500-liter capacity.

Essentially, this means that even if you use it daily, you can expect it to last you more than a year.

The Good

For its compact size, the 1,500-liter capacity is sure to impress anyone.

It helps make surviving in the wilderness a bit easier, as you don’t have to carry gallons of water on your back.

Since it can last you a year, you won’t need to replace it as often, making it a cost-effective hydration solution.

The Bad

This water-filtering device is generally great, but it can be pretty challenging to suck water through it, especially for kids.

Due to the low flow rate, it can be a challenge to back rinse it as well.

LoGest Mini Water Filter Straw, 4-Pack




Check Price

The LoGest Mini Water Filter Straw is a portable water-purifying device that comes in packs of four pieces.

It is small and easy to carry, so you can be sure you have a convenient way to get access to clean drinking water wherever you are.

Product Highlights

Measuring only eight inches by one inch, this survival water filter straw is compact and lightweight.

It even has a carrying strap so that you can hang it from your backpack for quick access during camping trips and hikes.

Designed to filter out salmonella, legionella, and E. coli, this device makes it possible for you to drink from unclean sources without fear of infection.

It also effectively gets rid of harmful chemicals, particles, and foul odor from the water.

This is all made possible by the hollow fiber membrane with a 0.01-micron filtration system that filters out up to 99 percent of contaminants.

Though small in size, it can filter more than 600 liters of unclean water, providing you safe drinking water for up to a year.

The Good

The weight of your backpack is an important consideration when hiking or camping.

Fortunately, the compact size of the LoGest Mini Water Filter Straw makes it very convenient to carry around.

With it, you will be able to drink from natural water sources, and you won’t have to pack your bag with bottles of water.

Filtering out up to 99 percent of harmful contaminants also means it can save you from dehydration when exploring the outdoors.

The Bad

The major downside to this survival water filter straw is its flow rate.

The advertised 500-ml-per-minute flow rate does not match the actual speed when you use the straw.

Sipping water from the straw can also be quite challenging, as the filter is vulnerable to clogging.

You can solve this by simply giving the water filters routine cleaning so that they can function properly.

SimPure Gravity Water Filter Straw




Check Price

The SimPure Gravity Water Filter Straw is great for groups or families exploring the great outdoors.

It is a bit different from the first three in that, more than just the straw, you also get a carrying pouch and a gravity-fed bladder.

With this, you can refill the bag as you pass through natural water sources and have the water filtered as you go.

Product Highlights

Because it comes in a complete kit rolled into one package, you will get the most bang for your buck in the SimPure Gravity Water Filter.

It comes with a superb water filter straw that can last up to 5,000 liters, as well as a reusable water bladder, a storage bag, and some more miscellaneous items.

This package is perfect for individuals looking to not only be able to filter water but also bring the purified water with them.

Most water straw filters are just that. You can only use them to directly drink from a water source. This product solves that issue for you.

You can hang the bladder, and the clamp for gravity feeding lets you turn it on and off like a faucet.

The 29.5-inch extension tube makes it convenient to get water from a natural source, fill up the bladder, and continue on your way.

The Good

The SimPure Gravity Water Filter has everything you need in a water filtration system on the go.

Using it is as easy as filling up the bladder with water, hanging it from a tree, and attaching the water filter straw.

You can set it up like a faucet, or you can drink directly from the straw using the various attachments included.

Thanks to the gravity-fed bladder system, several people can safely use this product at the same time.

The Bad

Even though this is a fantastic on-the-go water filtration kit, it does have some downsides.

For one, it can be a challenge to clean and flush out, leaving it vulnerable to mold after multiple uses.

The filter can also get clogged and is difficult to back rinse or backflush.
