6 Best Filtered Water Bottles

If you’re reading this I’d think that you have a soft spot for traveling to places where clean sources of water might be scarce. Whatever your reasons might be, it isn’t too bad to think about healthy and clean ways to consume water.

Without healthy water, you’re more prone to headaches and dehydration so in this article, we shall quench your thirst!

In this industrial age, a lot of water sources that we use every day are not as safe as we would like to think. Although everything has its ups and downs, even when it comes to filtration systems, it’s recommended to carry a filtered water bottle just in case.

Is A Water Bottle with a Filter Worth It?

Water bottles could provide healthy and safe drinking water for all you traveling folks out there, or for those who just aren’t into drinking tap water. Not only that but it’s a better alternative for the environment.

It doesn’t cost as much as a full filtration system while maintaining a degree of safety. As long as it’s healthy and tastes good I’m all for it.

How do Filtered Water Bottles Work?

There are many methods to water purification; these are two methods for purifying water that are popular, reliable, and healthy: UV filtration and Carbon filtration.

UV Filtration

UV filtration relies on individual compounds and mixtures to block or absorb bacteria, which makes it effective against most water-borne pathogens.

Moreover, Ultraviolet Germicidal Irradiation (UVGI) is a method that uses ultraviolet light to kill microorganisms such as viruses and bacteria. This method is similar to sunburn protection.

It was first discovered by a couple of fellows by the name of Arthur Downes and Thomas P. Blunt. The use of UV light to disinfect water dates back to 1910 in Marseille, France.

Carbon Filtration

Through a bed of activated carbon, carbon filtering is used to remove contaminants and impurities using chemical adsorption. This is the more common method but it isn’t as reliable when it comes to the bigger threats, like viruses and nuclear radiation.

But how does activated carbon work anyway? It’s called adsorption, it forms a barrier to attract those pesky little harmful molecules and trap them. The filters that use these methods need to be changed more frequently.

What is BPA?

Now when you’re researching for your purchase you might see the term BPA often. BPA this, BPA that. It refers to a certain chemical used in various industries by the name of bisphenol A, not the easiest name to remember but you should. It was used in the ’60s to manufacture plastic products, which is great, but it was later found that when consumed in large quantities, it may cause health problems. That is the reason you see the term “BPA-free” thrown around when it comes to filtered water bottles.

How do you increase the life-span of filtered water bottles?

It depends on the individual product, each with a weakness different from the other. That’s why before making a decision you should know why you are buying in the first place. The most common recommendation that goes for most products, however, is to only fill up the bottle when you intend to use it. Don’t fill it up and just let the water sit there forever.

What is the difference between a 2-Stage and a 4-Stage Filter?

The differences are not as clear as you may think. Every added filtration level adds a layer of safety. For example, a stage 1 filter removes big things like dust, rust, and silt. A stage 2 filter is a carbon activated filter – which we talked about – responsible for removing chlorine. A stage 3 filter uses reverse osmosis to remove organic and inorganic chemicals like Fluoride. The remaining stage is 4, which removes all remaining resolved solids from the water. So it goes to show that the more you go up in terms of number of levels, generally the better and safer.

Best Filtered Water Bottle Brands

You might see a lot of big name brands while doing research, but the ones we mentioned here are the most reliable options you can find, providing a wide range of features for varying user needs, from 4-Stage filters to specifically designed mouthpieces. To recap:

  • LifeStraw Go
  • SurviMate
  • Seychelle
  • Brita


In the end, it’s up to you, knowing what you want, you should have already made your decision, but just to go the extra mile it might be helpful to know what you’re shooting for.

Are you a hardcore traveler that spends all year long in remote locations where reliable water sources aren’t as available? Or you just hike from time to time when you feel like it?

The range of products supports many kinds of people. Your investment in a filtered water bottle not only provides you with clean water easily, but it’s also good for the environment, and I think that we should be more critical of our actions that have an effect on this world. Our future depends on it.
