5 Best Camping Water Filters 2019: All You Need to Know

Let’s get this straight. This article will show how to choose the best camping water filters. Therefore, the question is: “Are you a person who is into camping, or any other activity like hiking, fishing, and so on”? If so, I’m pretty sure you all understand that apart from camping tent and gear, water treatment is extremely important, especially to maintain our health when we are in the outdoors.

However, for anyone who hasn’t experienced any outdoor activity like that, I will explain what I’ve just said. Not every water source out there is unsafe but remember that even a pristine-looking water source can totally make you sick.

In general, as far as we’ve known, contamination levels are rising considerably over time. Now, the question is: “Why do you have to risk your life when you already have different options for treating the water?”

That’s the exact reason why we are here to help you. In this article, we will offer you guidance on how to determine the best camping water filters. Let’s get started.

How Water Filters Work

Before moving on to the main part of the article, it’s necessary for you to understand how water filters work. Therefore, you will know the exact reason why you should buy it for your camping trip.

Overall, a water filter pushes water through a filter mechanically, straining out protozoa and bacteria. However, it doesn’t kill the virus, so don’t mistake a water filter for a water purifier.

In details, every water filter has an internal cartridge or element. This is a component which has microscopic pores catching protozoa, debris, and bacteria. Over time, strained matter gyms up a cartridge’s pores, thus, the cartridge needs cleaning and replacing eventually.

Why you should use a water filter

If you still want to know why you should use a water filter, then the following are ten reasons for you:

If you want to capitalize on the health benefits of water, a water filter is very important for you to draw from a clean source of water.

There are about 2100 drinking water contaminants which can totally be in tap water, including some known poisons.

Drinking contaminated water will probably result in epidemic disease in even developed countries.

Bottled water cannot always provide a viable alternative to tap water.

A point-of-use filtration system is the only way for us to ensure contaminant-free and pure water.

Almost all municipal water treatment facilities are not able to control the outbreak of dangerous contaminants in tap water.

The presence of toxic materials in drinking water can totally be the main cause of several types of cancer.

According to the EPA, lead in drinking water led to about 500,000 cases of learning disorders in children every year only in America.

Drinking clean, healthy is essential not only for children’s physical development but also their mental health.

It’s even more essential for pregnant women to drink clean water as contaminated water can completely result in severe congenital disabilities.

Things to consider before choosing the best camping water filter


We all want to buy a portable water filter which is easy to carry during the camping trip or any other outdoor activity. This is an extremely important factor, especially when you know you will have to move all the time.

Just imagine that you are going to set up a basecamp. In this case, a 0.1-micron water filtration system from Sawyer Products with the dimensions of 13.75 x 3 x 9.25 inches is totally fine.

However, if you plan to hike long distances, then a Katadyn Pocket Water Filter is a perfect choice. This is because the item dimensions are 1.5 x 5.43 x 2.56 inches. Or you can buy a small one like LifeStraw Personal water filter.

Any camping water filter is already portable when you are going on a camping trip or any outdoor activity like that. It just comes down to your preferences and comfort. Therefore, instead of worrying about what to buy, just choose anything you feel will be easy to carry and use, that’s all.


The output is also another important factor to consider when choosing a camping water filter. In case you are on a solo short-term trip, then this will not be a real matter.

However, what if you’re going to provide water for a whole group or want to filter a lot of water? Well, in this case, it’s time to consider buying a pump water filter. This is because the filter can treat as little or as much water as you need very easily. Moreover, the gravity filter excels in this area, and it can collect and treat a huge amount of water in a short amount of time.

Removal Abilities

When it comes to removal abilities, we need to mention filter medium. A filter is a material which catches the organisms in the contaminated water. Here are some types you can choose from:

Ceramic: an earthen material which is the same kind of stuff which our coffee mug is made out of. It has a long life and can be easily cleaned a lot of times before being replaced. Besides, a ceramic filter comes with a carbon core. Thus, it can remove chemicals from water quickly. Unfortunately, it is likely to get clogged. However, it is pretty easy for you to scrape clean.

Hollow fiber: This filter is made up of hollow U-shaped micro tubes, therefore, it allows the water to go through small pores. Additionally, the water will also travel into the core, where the contaminants are eliminated.

Fiberglass: This material is more fragile than ceramic but still very effective at removing particles.

Silica Depth: With silica sand which is finely grained, this filter can work by using multiple levels of different sized grains, from finest to largest. This one can catch different sized organisms as well as particles effectively when water travels through the levels of density.


Pump filter

With this filter, you need to drop the intake hose into the water source and the outlet hose into your bottle. After that, you work the pump. Some of these products directly thread to a reservoir or bottle.

  • Process precisely the amount of water you want.
  • You can replace the internal cartridge easily.
  • Can completely pull water from shallow water sources and seeps.


  • You need to have field cleaning for the cartridge quite often.
  • Sometimes, it’s quite annoying to work the pump, particularly at the end of the cartridge’s lifespan.
  • Bulk and weight are much greater than other products.

Gravity filter

To use this one correctly, you need to fill the reservoir, find a right place to hang everything up and just wait for the clean water. A lot of models come with an inline filter and a pair of reservoirs., However, the exactly provided water containers and setup can still vary.

  • You will find it easy to process a large amount of water for your whole group.
  • Unlike the previous one, you don’t have to do any hard work. Instead, gravity will do the work for you.
  • You can replace the cartridge.


  • It is difficult to find a place to hang the reservoirs.
  • Treatment process normally takes you much longer than a pump filter.
  • You frequently, need to have field cleaning for the cartridge.

Bottle filter

With fill-and-sip simplicity, this bottle has built-in filtration elements. Some products utilize the suction provided as the user sips from a bite valve. However, some other products work the same way as a coffee press.

  • You can easily replace the cartridge.
  • This product is lighter, and it costs less than other water filters.


  • The smaller the bottle, the less water.
  • You frequently need to have field cleaning for the cartridge.

Squeeze filter

This filter is just like a bottle filter except that users have to fill a small reservoir, then squeeze water through the filtration cartridges.

  • The treatment is quite easy.
  • You can easily replace the cartridge.
  • Some products double as a straw-style filter or gravity filter.
  • This filter is lighter, smaller and costs less than gravity and pump filters.


  • The amount of water is limited by flask, reservoir and bottle size.
  • You need to have field cleaning for the cartridge quite often.


Protozoa: this group includes the most common waterborne illnesses which are Cryptosporidium and Giardia. They are single-celled parasitic organisms that can result in intense intestinal problems. The symptoms appear anywhere from 2 days to even four weeks from ingestion. They can also live in cold water for a very long time like months.

Viruses: Rotovirus and Hepatitis A are two common examples of viruses. They are extremely small. Thus, they aren’t strained out with almost all filters out there if the pore size is .02 microns.

Bacteria: There are so many different bacteria, for examples, Campylobacteriosis and Dysentary. These pathogens can live well in water, but fortunately, we can easily filter out and treat them. This is because they are much larger than viruses and bacteria.

After you know about the risks of water-borne pathogens, you have to learn how to prevent these illnesses with water filters.

In details, a water filter can eliminate Cryptosporidium and bacteria, but not all viruses. The product can strain out particulate, and it can also improve the taste of the water. Most water filters out there have pore sizes which are not small enough to filter out tiny viruses. That’s the reason why you have to buy a water filter coming with an extremely small pore size.


Another thing you should take into consideration is how heavy the treatment system is. In fact, common systems have drastic variance in weight, from a few ounces to even more than 22 ounces.

This can totally be more or less concern of depending on your outdoor activities. For instance, if you are hiking a long distance, then you should buy a small and light water filter. However, when it comes to traveling internationally as well as setting up a basecamp, a heavier but highly effective filter is the best choice.

Time before drinking

As I mentioned above, the time it takes for different filters to treat water varies wildly. However, in general, you have to wait about 90 seconds for a liter, or just 40 seconds for 6 liters.

If you are on a backpacking trip, then you will not want a filter that takes a long time to drink clean water. Instead, you need to have water as you go and don’t want to waste any time sitting around waiting for the water to be filtered. To me, an intermediate filter is enough for a personal filtration system.

Durability/ Uses before maintenance

If you’ve just bought a pump filter and preparing for a multi-day camping trip, you should look for a pump which is field maintainable. Therefore, you can service the filter yourself in the backcountry in case it gets clogged.

For instance, you need to scrap a ceramic filter quite often, but this is pretty easy for you to do. Many other pump filters are specifically designed so that you will find it easy to back-flush to remove clogs. However, it is still important to investigate how complicated this process can be, so you won’t get left helpless without water.

Additionally, it is also worth noticing how long the filter lasts before it needs replacing. For example, a ceramic filter can filter up to about 2,000 liters while many other products can only filter up to about 500 liters. Nonetheless, you can easily buy replacement elements if your filter has run its course.

Microns size

The smaller the pore size, the more pathogens the product can strain out.. Furthermore, the smallest bacteria is just 0.2 microns, thus, the best filter should be about that size of even smaller to be more effective.
