What are water purifiers for camping?

Camping water purifiers describe portable water cleaning systems that you can use during your stay in the great outdoors. When it comes to cleaning water whilst camping, there can be confusion between water filters and purifiers. A water filter is intended to remove waterborne protozoa and bacteria but not viruses. On the other hand, a water purifier is designed to remove protozoa, bacteria, and viruses, providing an additional layer of defense.

In most cases, options for camping are lightweight and compact allowing them to be quickly and easily stowed in your gear or your camping backpack should you be hiking to your campsite.

What should you be looking for?

The following factors should be considered as you look for a good water purifier to meet your camping needs:

  1. Type
  2. Weight
  3. Pore size
  4. Flow rate
  5. Additions


As you search for water purifiers for camping, you will undoubtedly encounter various options of different types. Here are the different kinds of water purifiers available:

  1. Gravity/inline purifiers: These systems, which use an inline filter and are ideal for groups, base camping, or any other situation where you need to filter large amounts of water while using minimal effort. Gravity purifiers are also straightforward to use in that you fill the dirty water bag, connect the filter to the port or hose and let gravity take care of the rest. Some gravity systems collect water in a separate “clean” container, whereas others dispense it directly into your vessel (or mouth) via a hose with an on/off valve.
  2. Pump purifiers: This purifier type is ideal for small groups (1-4 people), especially when drawing water from shallow pools. A pump siphons water from a source, through a hose and filter and out another hose into a clean receptacle.
  3. Bottle purifiers: These portable purifiers, also known as squeeze purifiers, attach to the spout of a soft-sided bottle or pouch and clean the water as you drink. Their lightweight and simple design make them an excellent choice for weight-sensitive trips and solo backpackers, day hikers, trail runners, cyclists, etc.
  4. Chemical purifiers: As indicated by the name, these purifiers use iodine or chlorine dioxide to rid the water of unpleasant components. These chemicals will eventually kill anything in the water while remaining safe for you to drink. Despite being incredibly light and compact, chemical purifiers take a long time to work (at least 15 minutes for 1 liter).
  5. UV light purifiers: These relatively new water treatment devices use UV light to disrupt the replication of bacteria and viruses in the water. They are quick and straightforward to use for small amounts of water, but they have the disadvantage of relying on batteries and electronics.


Water filters and purifiers vary in size and weight with most popular options for individuals weighing between 2 and 5 ounces. As with all backpacking gear, I suggest going as light as possible while maintaining functionality. Pumps and gravity systems are the heaviest and bulkiest, with numerous components such as storage bags and hoses.

Pore size

This feature refers to the size of the filter’s tiny openings measured in microns. The more particles the filter can block, the smaller the pore. According to the CDC’s water treatment guide, a pore size of 1 micron (or less) is required to filter out protozoa, while a pore size of 0.3 microns is required to filter out bacteria.

Flow rate

Flow rate describes how quickly the purifier treats water and is usually measured in liters per minute. Gravity filters have the fastest flow rates in general. Pump purifiers come next, with squeeze and straw types coming last.

Chemical and ultraviolet purifiers do not have a flow rate as they do not filter water. They do however have a wait time before the water is safe to drink, which is usually between 15 and 30 minutes for chemical purifiers and 90 seconds per liter for UV pen purifiers.


Other potential additions include:

  1. Carry bag: This item helps in safekeeping the water purifier so that it is protected from the elements, and you can carry the product easily.
  2. Ergonomic handle: If you are aiming to buy bottle purifiers, then look for products that have soft and nonslip pads.
  3. USB cable: For battery-powered camping purifiers, the USB cable becomes handy. This item helps recharge the gadget’s battery for smooth and efficient operation.
  4. Warranty: This feature guarantees that the product you will buy is durable and damage-free. However, ensure to read each manufacturer’s policy to optimize the warranty they provide better.


How do you purify water when camping?

When it comes to clean drinking water whilst camping, the surest method to kill the viruses, bacteria, and parasites found in water is to boil it. However if you don’t have access to the heat of a fire or stove, then a portable water purifier can be just as effective.

What is the difference between a water purifier and a water filter?

In short, a filter will generally remove bacteria, waterborne protozoa and some toxins. A purifier however will remove all of them plus more importantly, any viruses found within the water as well.

My three recommendations broken down

So based on the information above and my own experience, I recommend the following options:

1. FS-TFC 4-Stage Portable Water Filter Pump
