Top 10 Survival Water Filters

The first thing you will need in any survival situation is drinkable water.

You can go without food for several days but only hours without water.

Having good clean water will be key to keeping your body running.

Dirty water will make you sick quickly and put you in a very stressful situation.

If your putting together a survival bug out bag or just going out camping in a remote area – you will need a portable water filter to carry with you.

#10 MSR MiniWorks EX Backcountry Water Filter

I have had an original “white” model of this filter for many many years ago. I got this new MiniWorks filter and it works great. I get clean filtered water everytime. I consider the it to be my gold standard for water filters. It works flawlessly and effortlessly. I have had other filters but they are always more difficult to pump.

This one has never let me down. You would also find that the company honors the lifetime warranty without question. Great company. I will go out of my way to find products by Cascade design (they have the MRS brand) now because of their great customer support. I called them and told them the center stem had cracked on my 25 year old model and they had me send in the cracked stem and sent me a new one within a week. Another customer I met in a store here told me the same story about his old filter. He also had the same experience with them honoring their warranty.

#6 Aquamira Frontier Filter System

I bought the Aquamira Frontier Emergency Water Filter System as a lightweight way to keep safe and not get sick from water-born illnesses (Cryptosporidiosis and Giardiasis being the two major ones) while abroad.

I still carry water filtration tablets while abroad as a “just in case” item, but let’s face it – that’s a pain to deal with and you need to be planning ahead. Sometimes you just need to drink now.

I really can’t get over how light this thing is. It weighs less than an ounce, and fits easily inside of any pocket you can think of. The collapsible straw is a bonus.

The straw is rated at being able to filter around 20 gallons of water before it’s discarded.

#5 Katadyn Vario Filter

I recently went to the Ecuadorian Amazon and spent a week living in the rain forest with indigenous people. I went on long treks and relied on the Katadyn Vario Multi Flow Water Microfilter to deliver drinking water from streams I passed on the way. The fact that I never got sick is a testament to the effectiveness of the Vario. It was easy to hook up directly to my CamelBak, so there was no chance of contamination.

Whenever I used it, I had it in the “longer life” setting where you pump a little less water per minute, but it passes through both filters inside. I’ve used several other filters and the speed and ease which I was able to fill up my 100oz Camelbak is far superior to any of them. The pumping motion is easy to use and it pumps a lot more water even on the “Longer life” (slow) setting than other filters. Overall I think it is a fantastic product that I would recommend to anyone traveling to locations where you don’t know if you can trust the water.

#3 Sawyer Mini Water Filtration System

So first off, let me say I ordered this with my Prime account, and it comes with free 2-day shipping…it got here in 1 day. I immediately took it out in the backcountry for a day hike with the dog to give it a try/test in the field. We made it to a nice frozen shoulder of the Rattlesnake Creek in Missoula, MT. The temp was below freezing, i’de say 30F, or somewhere around there. I chipped through an ice shelf on the creek and dunked the bag into the ice cold water.

Filling it was easy with the current but I can see some wishing it came with a bigger bag because it doesn’t look like much when the bag is filled. I will probably use a 32oz Platypus bag I have in the future, and carry the included 16oz bag as a backup! Anyway, I screwed the Sawyer Products SP128 Mini Water Filtration System onto the bag, tipped it upside down and water came out with a very effortless squeeze. After I got done laughing about how simple this was, I gave Yoshi a drink as well (my English Bulldog). He also took to it well, as he’s a big fan of drinking from water bottles anyway. So yeah, this is a dog friendly design!

#2 Berkey Sports Bottle

I’ve used this product on several trips to Europe. I’ve been pretty healthy and I thank my Berkey Sports Bottle for that. In the past, I blamed air travel for the “bugs” that got me down while or just after traveling.

Now I’m pretty sure that it is the drinking water. They just do not have the same drinking water as back home. I also use it at work because it’s better than wasting money on plastic bottles and loading the landfill.

This bottle is versatile and the ideal size at 22 oz. The Sport Berkey Water Filter Bottle with replaceable filter is ideal for everyday use at home, school or the office. It’s also great for taking along while biking, working out at the gym, traveling and more.

It uses the same filtration formulation as Black Berkey Elements, which are used in our popular outdoor gravity-fed systems. It has been tested by multiple independent third-party labs for its ability to remove or reduce typical contaminants found in drinking water sources. The filter is good up to 640 refills of municipal water. I would replace the filter sooner if you are drawing water from a local stream or lake. I like that it is made from a non-leaching, LDPE #4 medical grade polymer, which is BPA-free.

#1 LifeStraw Personal Water Filter

For the weight, I believe there is no better backcountry water treatment available. The LifeStraw Personal Water Filter imparts no strange flavors like its chemical brethren, its flow rate is perfectly acceptable for active pursuits, it has no moving parts to break or filters that need replacing every couple of days, and it does all this at a fraction of the cost and weight of other Filter and UV water treatment options.

Besides, what other water treatment system has been tested successfully by people on a daily basis in the most contaminated parts of our planet?

When would you need a survival water filter?

You’d need a survival water filter when you’re in situations where clean drinking water is hard to find or might be contaminated. For example, if you’re hiking or camping in the wilderness and need to drink from rivers or lakes, a survival water filter helps remove harmful bacteria and particles, keeping you safe. In emergencies like natural disasters where water supplies can get contaminated or cut off, having a survival water filter ensures you can purify water from various sources for drinking. Even during adventurous travels to remote areas or if you’re stranded without access to clean water, a survival water filter becomes essential for staying hydrated and healthy. It’s a smart tool to have whenever clean drinking water isn’t readily available.

Note: Several of the systems have been tested by SGS International
