Top Rated Backpacking Water Filters

Top Rated Backpacking Water Filters for 2020 [Amazon Best Sellers]


If you are preparing for the trail, you will need one of these top rated backpacking water filters prepared for you here in the list, all reliable Amazon best-selling outdoor tools.

What is in the list

So here you have water filters for hikers, backpackers, campers, travelers, etc. You will need them in any of these and similar activities. I myself am an active mountaineer and hiker and I have one of these filters always in my backpack. Without a water filter, I normally need up to 3 liters of water for a whole day activity in the mountains. This depends on the weather conditions and on how hard the activity is, so sometimes this cannot be enough. My backpack feels very different with and without such an addition.

But if I go in the area with lots of water springs and flows, I normally only have one 3/4 liter bottle of water, and then refill occasionally whenever it is necessary. My strict rule is never to drink the water without filtering it first, regardless of how clean it can look.

The items in the list are in any of the following two groups:

  • Water filters.
  • Water purifiers.

Now, when this is about mechanical process of cleaning the water, a purifier is a filter as well, but a filter is not necessarily a purifier. This is about the size of the pores through which the water is filtered. A purifier is able to remove all living organisms, viruses included. Water filters cannot remove viruses, some of them are too small. But if you are on the trail, having viruses in water is very unlikely, they need living creatures to survive, and they do not remain in the water for long. So in most cases, you need just a good filter and you will be safe.

If you would rather have some purifier that does not remove microorganisms physically, but kills them instead, please check our separate list.

So how to know which is which and how to choose?

  • First, you have to be sure that the item is reliable, and I am sure this is not always so. But you will see the top brands here in the list, those are the most reliable in this industry, like MSR, Sawyer, Katadyn, LifeStraw, and a few more.
  • Second, as mentioned above, this is about the size of the pores in the filter/purifier. Viruses are usually 0.02 – 0.4 microns size, the smallest seems to be the Porcine circovirus type 1 with a diameter of 0.017 microns. So if you have a system with filtration pores that are 0.01 micron, you are pretty much safe from any virus and bacteria. 

Note that such filters and purifiers do not remove chemicals and pollutants, though some of them can reduce the amount of some of the chemicals. So it is best to avoid taking the water from places where such stuff may be present. These tools also cannot make fresh water out of seawater.

These are outdoor tools, but it is good to have such items at home as well, for emergency situations in general and family preparedness, in particular in areas with hurricanes, and where floods are expected.

Regarding the size and principle of work, you can have the following types:

  • Small filters/purifiers to use on the go. This is what I use most of the time. Note that here you have two sub-types:
    • Filters/Purifiers which you use to drink directly.
    • Filters/Purifiers which allow you to collect clean water and carry on the trail, as you can see in the top picture above. I would suggest using this type, and this in particular if you do not know the trail which is waiting for you and have no idea where the next water supply might be. So here you have either i) a bladder which you fill with water and then squeeze through the filter into a clean water bottle, or ii) a system with a pump which takes the water from the stream and filter it into the clean bottle. The second option is a bit heavier and bulkier.
  • Gravity systems suitable to use when you are in the camp. So you put water in the reservoir and let gravity do the job, the water will flow through the attached filter and you will have the clean water collected in the container; meanwhile, you can do other things in the camp, cook, read, or just rest. These are camping water filters and purifiers but they can be used as water filters for hikers and backpackers as well.

These are all Amazon best-selling water filters and purifiers, many of them are Amazon Prime items so you can have them shipped for free. The differences in prices can be huge, but this does not mean those cheap items are unreliable. This is all about the technology used; some of those expensive items are heavier, with ceramic filters, and suitable for groups.

In any case, you have a number of the filters here that are on sale, a chance to save some money. So here is our list with best water filters for backpacking, hiking, and camping, please have a look:
