Taking along the best water bottle for air travel will go a long way towards making sure you are hydrated on any flight, short or long haul. Staying hydrated is not the same as ‘drink a lot,’ which can be interpreted in many ways, and one or two of them will not do you much good at all. Traveling with the best self filtering water bottle will filter out virtually all the bacteria and chemicals found in even the cleanest tap water, making it extremely healthy for you to drink en route. Our review will look at three of the best self-filtering water bottles which are suitable for air travel and highlight both positive and negative features, ensuring you choose the best water bottle for you.

LifeStraw Go Water Filter Bottle

The LifeStraw Go Water Filter Bottle has a capacity of up to 22 fluid ounces. There are no size variations, but for those of you who like to fly with everything color coordinated, including your self-filtering water bottle, there are up to ten different color options. There is one option which has two bottles instead of one, if you don’t mind one blue and one purple bottle.

Filtration System

This is one of the top filtration systems currently available to the extent it has won awards. It can literally take a glass of cloudy water and turn it to clear, and drinkable water and will remove the following undesirables:

  • Parasites
  • Bacteria
  • Chemicals
  • Chlorine
  • E-coli
  • Salmonella
  • Giardia
  • Protozoa
  • Odors

It does all of this without the use of chemicals such as iodine. Instead, its filters consist of a fiber membrane and carbon capsule which can filter particles as small as 0.2 microns. The filter units are also replaceable.


The mouthpiece is silicone based with enough flexibility to prevent it from cracking or chipping. For cleaning purposes, it can be removed.

Other Features

  • To attach the water bottle to a backpack or hand luggage, it has a carabiner
  • Every self-filtering water bottle purchase triggers a charitable donation which provides clean drinking water for one year for a child in a developing country

Pros LifeStraw Go Water Filter Bottle

  • Dual filtration system
  • Reusable bottle
  • Carabiner to attach to hand luggage
  • Choice of colors
  • Flexible straw

Cons LifeStraw Go Water Filter Bottle

  • Mouthpiece can be noisy when sucking
  • Filter replacements are not cheap

Brita Sport Water Bottle Duo Pack

If two of you normally fly together and want a water bottle for each, then the Brita Sport Water Bottle with 2 Filters will appeal to you. Instead of just one self-filtering bottle, you get two, and your only issue will be to choose who gets the blue and who gets the orange one.

Other options for this include a single bottle or three bottles. In both instances the bottles are blue, and the capacity of all bottles is 20 fluid ounces, which is about 1.25 pints.

Filtration System

Each Brita carbon-based filter used in their bottles can filter around 40 gallons of water before needing to be replaced, so this equates to around 256 full bottles of water. Even if you drank 4 bottles every day, the timescale is at least every 2 months.

The filtration system is BPA-free and can filter out chlorine, odors and minute particles of unwanted matter from tap water. This allows you to drink much cleaner and fresher water than drinking it straight from the tap.


The straw is designed to make it easy for you to sip from the bottle including while you are walking.

Other Features

  • The bottle is soft, so you can squeeze it to promote the water flow
  • It has a plastic loop which can be used to carry it
  • It is dishwasher safe, but on the top rack only

Pros Brita Sport Water Bottle with 2 Filters

  • Two bottles equal better value for money
  • Looped handle for carrying
  • Single or triple bottle set available
  • BPA free filter system
  • Dishwasher safe

Cons Brita Sport Water Bottle with 2 Filters

  • Does need quite a squeeze for water to come out
  • Bottle is very slippery if your hands are wet

KOR Nava Reusable Self-Filtering Water Bottle

The KOR Nava Reusable Self-Filtering Water Bottle has a capacity of 22 fluid ounces, along with a variety of trim colors, such as pink, blue, black, and green. As with most self-filtered water bottles, the filter is carbon-based but what makes this one different from the others we have seen, is the filter unit is made from pure coconut shell. This ensures that as much of the bottle as possible is made from natural materials. The filter is designed to remove chlorine, odors and bad tastes from tap water, and has been certified to Standard 42 by the NSF.


The water flow system within this bottle is one of the best around. It utilizes a patented ‘EasyFlow’ technology so you do not have to use excessive suction or biting on the straw, nor do you need to squeeze the bottle tightly to get a drink of water.

The straw is housed in a cap which protects it when not in use, and when you do want to use it, you simply press a button and it opens.

Other Features

  • The base of the bottle is cushioned so it won’t damage or scratch delicate surfaces if placed upon them
  • To ensure it is comfortable when being held in your hand, the manufacturers have used an ergonomic design for the exterior of the bottle

Pros KOR Nava Reusable Self-Filtering Water Bottle

  • Cushioned base
  • Natural coconut shell filter unit
  • Push button to open straw
  • Ergonomic design for comfort
  • ‘EasyFlow’ system for easy drinking

Cons KOR Nava Reusable Self-Filtering Water Bottle

  • Straw makes loud noises when drinking
  • No carrying loop


We’ve looked at three very different self-filtering water bottles which can be used for air travel, and each of them has their merits. If the quality and the purity of the water is your utmost concern, then the award-winning filtration of the LifeStraw Go Water Filter Bottle should appeal to you. The carabiner also makes it the best one for attaching to your hand luggage.

For value, getting two bottles instead of just one can’t be bad, and that is exactly what you get with the Brita Sport Water Bottle with 2 Filters. Finally, we have what we believe is the best-looking bottle and the one with the best design, thanks to a unique coconut shell filter, a cushioned base, and a button to release the straw.

So, the choice you have in picking the best water bottle for air travel is deciding whether water quality, value for money, or design is your top priority.
