Features to look for when buying a portable water filter

Having access to clean drinking water is the number one priority for every human and living being. If you like to go on adventures to exotic destinations or on camping or other outdoor trips, then having a reliable portable water filter can help you stay hydrated, safe from parasite and bacterial infections, and can literally even help save your life.

A portable filter should be easy to carry without taking up too much space but should still be capable of providing you with water that is safe to drink from any fresh water source.

Since there are so many different types of portable water filters, it can be hard to choose the most suitable one for your specific needs.

Here are the main features to look for, and the factors to keep in mind when shopping for the best portable water filter for traveling, hiking, or for emergencies and disasters.

Its size and weight

Obviously, if you want a portable water filtering system, you should look for one which is compact and lightweight enough so you can carry it with you when you are outdoors or traveling.

As you can see from the products on our list of the best portable water filters for 2020, all of them are small enough to be carried and stored easily.

Some are larger than others, and some have larger capacities than others.

This is why you should make sure that you decide whether you are looking for a personal water filter or for one which can be used by an entire family or larger group of people when choosing the right size and capacity.

The water filtration speed

Each portable water filter purifies the water from bacteria, parasites, and other harmful microorganisms and pollutants at a different speed.

While some of the filtering systems can produce just a few ounces of water per minute, others are capable of purifying up to 20 or more ounces of water for a minute. The filtration speed is especially crucial if you will be sharing the water filtering system with other people.

The filter cartridge capacity

Every filtering media has a specific filtering capacity or lifespan. While some will last for a few days only, others can be used for several weeks and even for months. Some of the filters on our list have a very long shelf-life, so they are perfect additions for your emergency or disaster kits.

Depending on how much you are planning on using the filtering system, you should opt for one which can filter from 264 gallons up to 1,000,000 gallons of water per cartridge.

The ease of use

Aside from being portable and easy to carry, good water filters should be easy to use too, especially in harsh outdoor conditions. One of the easiest types to use is the straw filters, which are actually straws with integrated filters in them, which you can use by sucking in the water directly from the source. Others require that you do some pushing or pumping, and some filters use gravity to filter out the impurities from the water.

But overall, all of the products we have picked for you are quite easy to use, so whichever one you choose, you shouldn’t have difficulties using it.

The price of the filter and cartridges

It is a good idea to set a budget for a portable water filter, and then proceed to look for the best one within your price range. There are filtering systems that cost less than $20, while others can cost significantly more. Keep in mind that it is a good idea to check out the price of the replacement cartridges as well, in order to calculate how much the maintenance of your portable filtering system will cost you in the long run.

The type of portable water filter

As you may have noticed from our list, the portable filters vary in type, so picking the best one may be a tad confusing, especially if you are a first-time buyer and user of such a filter. Here are the main types of portable water filters and their pros and cons:

Straw Filters

These are the most compact and lightest of all types. They are designed to look like and be used like straws but have integrated filters in them, which will filter the water as you suck it directly from the source.

These filters usually will be able to trap any virus, protozoa, and bacteria as small as 0.2 microns, and will prevent them from passing into the water which you suck in. They do require that you get very close to the water source. They also require quite a bit of suction from your side, which could be an inconvenience for some people and in some situations.

Pros:

  • Very light and compact
  • No waiting is required for the water to be filtered
  • Removes bacteria, parasite protozoa, and other microorganisms
  • Removes bad taste and odors
  • Great for ultralight backpackers

Cons:

  • You will need to get close to the source which can be a hassle if it is a lake
  • They require suction which can be difficult in hard outdoor conditions, such as at a high altitude
  • The filter can easily get clogged by larger particles so that it may require frequent unclogging and cleaning
  • Not as efficient in removing chlorine, heavy metals or pharmaceuticals

Pump Filters

These are not the most compact of all portable water filters, but the models we have picked for you are still small enough to fit in your backpack. These filters work by manually pumping the water from the source into the clean water recipient.

Some pump filters have ceramic or fiber filters, and others combine these with activated carbon filters to filter out contaminants as small as 0.5 to 1 microns.

Unfortunately, some types of bacteria are smaller than that at can pass through the ceramic filter to the water you will be drinking. Also, such filters are not capable of trapping organic compounds.

This is why, if you want a portable pump water filter, you should opt for one which has both a ceramic and an activated carbon filter.

Pros:

  • They have larger water filtering capacity than personal water filters
  • Great for wilderness backpackers or day hikers
  • Improve the odor and taste of the water
  • When combined with an activated carbon filter, they can be very efficient for the removal of bacteria, protozoans, microplastics and other pollutants from the water
  • The healthy minerals remain in the filtered water

Cons:

  • They do require pumping by hand
  • They may not be able to filter out some of the smaller microorganisms
  • The filter cartridge needs to be changed regularly in order to prevent bacterial growth inside it

Bottle Filters

This type of portable water filter is more versatile than others, as you can use the water bottle as a regular bottle when there is no need to filter the water. When you want to drink water from an unchecked source, all you need to do is add the filter cartridge, and you will have filtered drinking water.

Some bottle filters use fiber filters, while others use solid block activated carbon filters for purifying the water. The former usually have filter cartridges, which are actually straw filters, and which can be used as separate straw filters if you prefer. When used with the water bottle, the straw filter is easier to use, as you don’t need to bend or lay down to get close to the water source if it is a lake, pond, or other.

Pros:

  • They are more versatile than others, and the bottle and straw filter can be used separately
  • They efficiently trap bacteria and parasite protozoa
  • They keep the beneficial minerals like calcium and magnesium in the drinking water
  • An excellent option for day hikers and for hikers who prefer to go ultra-light

Cons:

  • Many of them are not useful for filtering out nitrates, fluorides or cadmium from the water

Gravity Filters

Gravity filters, as the name suggests, rely on gravity to filter the water. This means that they require no effort from your side, like pumping, pushing, or sucking. All you need to do is add water to the dirty water reservoir, connect it with the clean water tank and hang them on a tree branch, on the tent or anywhere else, so that the contaminated water from the top tank flows through the filter and into the drinking water tank which should be placed at a lower level.

Gravity filters are very suitable for camping and hiking trips, and for larger groups of people. They usually have a high water filtering capacity and can be used for washing your hands, and even as a shower when in the wilderness

Pros:

  • They require little physical effort to work
  • They are capable of filtering larger quantities of water for a shorter time
  • They can remove protozoa, bacteria, pesticides, herbicides, chlorine and other contaminants from the water
  • Their filter cartridges have a long shelf life and a high capacity

Cons:

  • They are larger than other filter types
  • They include several components which need to be stored in a way to prevent cross-contamination of the two reservoirs
  • A superb option for car campers and all types of camping of larger groups of people

UV Filters

UV Filters are not as popular because they rely on batteries to run, and as such, are more expensive and more difficult to use when in the wilderness.

But a UV water filter is highly efficient against parasites and bacteria and works very quickly.

Pros:

  • Efficient against viruses, bacteria, protozoa, and other microorganisms
  • Works quickly and is easy to use
  • It helps remove the bad taste and odor from the drinking water
  • It does keep the healthy mineral content in the water intact

Cons:

  • It requires batteries to work, which is not a good option if you are planning on long trips without access to batteries, or to a power source

Water purifying tablets

These are easy to carry and easy to use, and will not only help improve the taste and odor of the potable water, but will also help protect you from dangerous parasites, and bacterial or viral infections when drinking from contaminated water. They are also usually the most affordable of all types of portable water filters.

Pros:

  • They are small and easy to carry
  • They have a long shelf-life
  • They are easy to use
  • Many of them can successfully kill harmful microorganisms including viruses

Cons:

  • Some of the tablets require that you wait for several hours before you can safely drink the water
  • Depending on the chemicals used, they may have a chemical taste or smell or may have a negative effect on people with sensitivities to these chemicals

Final words

Hopefully, we have helped you resolve the dilemma about the best portable water filter to buy for your specific needs. As you can see, these products are relatively inexpensive, but can actually save your life, or protect you from some very nasty infections when you are traveling abroad, or exploring the wilderness.

A reliable portable water filter is a must for any household as part of an emergency or disaster kit, as well as for anybody who loves spending time outdoors.
