The Best Prepper Water Filtration Tools for Survival

Last Updated on 1 year by Todd

A couple of months back, we friends went for camping at Green Mountain National Forest, Vermont. The trip was adventurous indeed but it gives a small yet fruitful lesson to me that always keeps a prepper filter with you when you are going for camping or hiking.

So what happened actually, on one unfortunate night, I lost my way towards my camp. It took me around one and a half day to find my group’s camp. I had no food and no water. The only option I had was to drink puddle water that was surely full of contaminants. But luckily, I had an emergency water filter in my backpack and that was the most precious thing to me at the time. Best Prepper Water Filtration Tools

Still, it’s precious to me.

Indeed it saved my life.  So that day I learned a lesson to keep a portable water filter in your bag always.

Prepper water filters are meant to be used by preppers in emergency situations that may occur anytime. Just like me. These water filters give clean and pure water instantly without wasting any time. Usually on camping or hiking, when you don’t get clean water, then it’s time to use an emergency filter. They are so simple and easy to use. You can purify even the lake or stream water.

So without wasting further time, let’s check out the best prepper water filtration tools for survival

Best Prepper Water Filtration Tools for Survival

Choosing the best survival water filtration system could be a bit tricky task, especially when you do not have complete knowledge about the product. Since I have researched a lot before buying a survival water filter for myself, so that’s why I have decided to review some best survival water purifiers. Let’s Review the best water purifiers for camping.



1. Sawyer Products – Best prepper water filtration system

The first one on my list of best survival water filters is a super amazing and quite reliable water filter.

Sawyer mini water filtration is without a doubt is the best among the entire emergency water filter.

I purchased this filter a few months ago to put in a survival/camp pack, and it’s now filtered approximately 40 liters of water. This filter transforms murky lake water to crystal clear and delicious drinking water, as well as questionable garden hose water. I was at first hesitant, of course. Who would believe that brown, dirty water may be made clean and completely safe with such a little, inexpensive filtering device? But have no fear; this filter is a powerhouse that keeps on delivering.

I really love my filter water bag (Link below). It’s less than $10, just like the container you get with the filter, but it allows you to filter 70oz rather than 16oz. I also picked up a grommet kit from a local craft shop and inserted two grommets in the bag’s seam. After that, I threaded one foot of para-cord through the grommets and hung the bottle on a tree limb or anywhere else convenient.

It’s compact but a high-performance water filter, that filters out 99.99% of all the bacteria and protozoa. All thanks to its 0.1micron filter line that holds all the harmful bacteria, viruses, and protozoa.

So this means when you are short of filtered and clean water, Sawyer mini water filtration system promises to give you healthy and hygienic water every time you need it.

Besides this, the Sawyer water filtration unit is so small and petit in size that you can easily keep it in your backpack. The best part is, you won’t even feel its weight as it weighs only 2 ounces.

You know what; Sawyer guarantees you pure and clean water. The reason is every sawyer filter is performance tested three times during the manufacturing process.  Just to ensure you safe and healthy water.

But you have to keep an eye on the filter lifespan, as you have to replace the inner filter after consuming 100,000 gallons of water from it.

Sawyer mini water filtration system is quite budget savvy as you don’t need to buy special water bottles for using it. You can even use this filter with normal water bottles or you can even stick it directly into your water source.

Upon ordering the sawyer mini water filtration system you will get Sawyer mini filter, a 16-ounce re-useable squeeze pouch along with a drinking straw and cleaning plunger.

So if you are in dire need of the best survival water filtration system, then Sawyer mini water filtration system is the perfect choice for you.

The filter straw is equipped with three filtration levels. This first one is a pre-filter which is situated at the base of the filter straw. This part will come in contact with water and therefore it protects the large contaminants from entering into the filter straw.

Then come the antibacterial activated carbon filter which is mixed with ion exchange resin. This will remove chlorine, heavy metals ions, and eliminates the unpleasant odor.

Water enters through the pre-filter then moves towards the activated carbon filter. In the last water will pass through the 0.01µm hollow fiber UF inline membrane.

I drank water from two different creeks while backpacking. I did not get sick or die and the water tasted great. The only thing that would be better is if the cap had reverse threading so a water bottle could be screwed into it to force water through for camping and pouring into a pot or canteen for later.

7. Miniwell Gravity – Best water filters for preppers

miniwell Gravity - Best water filters for preppers

The last one on my list of best water filters for emergency preparedness is a gravity water filter from the house of MiniWell.

Let me make it clear to you, it’s not a personal water filter. In fact, it satisfies the demands of a group of people.

It is so efficient and simple to use. I still can’t figure out why this gear hasn’t got any attention as it should be.

Well, let’s see what this is and how it works.

MiniWell gravity water filter is quite different from the pump filter and straw filter.

It works by the action of gravity.

You will receive a small pocket size filter with some essential accessories, which include,

Unfiltered water reservoir, which will hold the contaminated water

Clean water collapsible bottle, which will store the clean and purified water

Tree strap, which will be used in fastening the water reservoir bottle to any suitable place.

Hose and hose clip, for transferring the unfiltered water towards the filter.

Its working is quite simple, all you have to do is just fill the unfiltered water reservoir with some contaminated water and hang it on the tree. Connect the filter and hose to clean water bottle. And that’s it, ultra-light gravity filter is ready to be operated under the action of gravity.

On a two-day backpacking trek in the Colorado high country, I used this to filter water. I filled the raw water from a glacier runoff supply since the sediment level was near zero, with the goal of removing pollutants such as moose and other animals. It filtered quickly and the clean water reservoir was a lifesaver for convenience of use. My only criticism is that holding down the bag’s lock was difficult. I’m a carpenter who believes he has decent hand strength, and despite my best efforts, I couldn’t get it on.

The filter is efficient enough to produce 2000L of fresh and clean water. The pore size is 0.1 micron which means you will get water that is free from bacteria, dust, and protozoa.

The best part about this gravity water filter is, you don’t need any syringe or any other tool for backwashing the filter. Backflushing it is so easy. Just invert the entire setup and you will have a clean water filter in minutes with you.

The clean water reservoir is capacious enough to serve the whole group of people. It has got 3 liters of capacity. The reservoirs are made up of high quality of food-grade material with convenient and comfortable handling.

MiniWell gravity water filter is the best choice for hiking, camping, canoeing, fishing, hunting, traveling, and survival supplies.

  • Gravity driven water filter
  • Can be backflushed easily with no effort
  • Provides clean water whole group
  • High lifespan of the filter
  • Can’t withstand heavy sediments in the water.


How to Get the Most Out of Prepper Water Filtration Tools:

Sometimes in the worst scenario, puddle water may be the only drinking option. Your emergency water filter will efficiently filter out the harmful elements from this dirty water. But there are several ways that may increase the filtering efficiency of your survival water filter. This way you will have extra clean and pure drinking water. In order to deal with such a situation there are several ways to follow:

  • Let the contaminated water settle out naturally

So before treating the dirty water in a portable water purifier, it is recommended to let the water settle out naturally. For this purpose a wide mouth water bottle is suitable. Pour water into the bottle and wait for the sedimentation process to occur. It will take time like 30 minutes. After that, you will have clean water at the top with all the dirt particles settled at the bottom.

Now you can further treat this water in an emergency water filter.

  • Filter the water using cheesecloth:

If you do not have any water bottle with you then you can filter the contaminated water using a cheesecloth or even a white thin cloth may work.

With this process, you can quickly eliminate a lot of dust and debris. Again, this process will require some time. The dirtier the water, the longer it will take to filter.

After filtering through cheesecloth, now you can filter this water in your survival filter. By doing so, you are increasing the life of your portable water filter.

  • Don’t let your filter freeze

If you are in a survival situation where you are forced to bear the cold temperature then make sure to empty your filter properly after each use. As if you let your filter freeze, then it will be entirely ruined regardless of the fact how new the filter is. You can keep the filter close to your body in order to protect it from freezing.

What is better than LifeStraw?

The LifeStraw is a great device, but it’s not nearly as useful as the Sawyer Mini. It has a 0.1 micron filter (versus 0.2 micron) and can clean up to 100,000 gallons of water (versus 4,000). While the LifeStraw is also an outstanding product, it pales in comparison to all that the Sawyer Mini can accomplish.

The removal of salt from sea water, making it drinkable, is known as desalination. This is either done by heating the water and capturing the steam (therm) or passing it through special filters (membrane).

Can you drink ocean water with LifeStraw?

If you want to use the LifeStraw to make water safe and drinkable, it won’t remove salt. So it’s probably not a good idea for your yacht’s emergency lifeboat kit. It must never be used with seawater or water that has been chemically contaminated.

What does the LifeStraw not filter?

The LifeStraw can’t remove mineral salts, heavy metals, chemicals (except chlorine), or viruses. It is not intended to alter the water’s pH and is only meant to filter biological pollutants.
