Moreover, according to a study, around 22% of the water sold by various bottled water brands contains free radicals that are above the health limits regulated by the state – this means an increased chance of contact with contaminants, such as E.coli.

If the previous statements didn’t make you consider buying the best filtered water bottle out there, then we inform you that at least 400 thousand barrels of oil are used to manufacture plastic bottles in a single year, of which only 30% are recycled.

The Magic Behind Your Filtered Water

best filtered water bottle

Of course, after reading so much about filtered water bottles, you wonder how they actually work. Well, we are here to provide you with that kind of information and so much more. Stick with us and, in the following paragraphs, you’ll find everything about the magic that happens behind every bottle that can filter your water.

The Heart of the Filtered Water Bottle – The Filtration System

When it comes to the filtration system of a filtered bottle, you have systems that clean your water as you drink it or as you fill-up the bottle. However, there are three characteristics that also count as steps in the filtration process which apply to both mentioned types.

Activated Carbon

Most filtered water bottles use a carbon filter; this uses activated carbon, known as activated charcoal, in order to remove any impurities from your water. You can check if your bottle has a carbon filter by looking at its bottom for black specks.

When it comes to water filters in general, they must be changed frequently, even if the black specks can still be seen.  We also have a blog post on how often you should change the refrigerator water filter, in case you are interested. Proper filtration is ensured through a process called oxygenation of the activated carbon. Basically, it is modified and degraded inside a controlled furnace in order to become highly porous.
After the mentioned process, the activated carbon has an increased ratio of total surface area per unit of volume. Therefore, it makes it easier for the next part of the filtration process to take place.


This is the most important process that takes place inside a filtered water bottle and basically encompasses everything related to it. Adsorption is in charge of atoms’, ions’, and molecules’ attachment to a certain surface.

Because the activated carbon now has an increased number of binding sites, it is much easier for it to remove any harmful elements that can be found inside water by simply binding to them. The carbon activated filtration system is very effective as ionized carbon has one of the highest numbers of binding sites across all chemical elements. Namely, four. Therefore, water filtration is an easy task for such a system.


Water filtration takes place when the activated carbon that the filter is made of absorbs everything that shouldn’t be in your water. Therefore, it’s only natural that it won’t have any more space to store bacteria and viruses after a certain number of uses. That’s why it is extremely important to replace the filter inside your filtered water bottle when it is recommended by its manufacturer. By doing this, you ensure the proper filtration of your water, no matter the location you take it from.

Complete Buying Guide on Filtered Water Bottles

You might not be entirely satisfied with our recommendations. On the other hand, you may not find the one you like available in stock. So, we have decided to come up with a filtered water bottle buying guide.
Naturally, there are some things you must pay attention to when buying such a product, especially if you plan on traveling a lot and want to make sure that you can rely on any water source that you may find outdoors.

Things You Should Consider When Buying a Filtered Water Bottle


When it comes to the filters that a filtered water bottle is equipped with, they can remove/filter up to three harmful things: chemical compounds, parasites and bacteria, and viruses. Chemical compounds are both organic and inorganic; arsenic, chlorine, copper, fluoride. These can reach water via natural or artificial means. For example, copper may find its way into your tap water through plumbing or such.

Parasites, bacteria, and viruses are usually found in any type of water we drink from tap water to bottled water, and so on. The most dangerous ones can be found in various water sources such as streams and rivers. That’s why, before buying a filtered water bottle, you must know what you are going to use it for. If it’s only for tap water, then a filter that deals with chemical compounds might be just enough.

However, if you plan on taking your bottle around the world, when hiking and traveling, then you should choose a bottle equipped with a filter that can deal with each of the harmful things mentioned above.

Type of Water Filter

As previously mentioned, most filtered water bottles come equipped with a carbon activated filter. However, there are plenty of them that have a UV filter instead. Not only that the latter is more expensive, but it also needs to be powered by batteries.

When compared to a carbon activated filter, a UV filter is not able to remove any chemical compounds that can be found in the water. On the other hand, they are much better when it comes to eliminating viruses and sterilizing water.

These two types of filters are also combined in some filtered water bottles. This offers you full protection in terms of chemical compounds, parasites, bacteria, and viruses. Check out the easy-to-use water testing kits for home use.

Quality of the Material

The material the bottle is made of should be of high-quality, such as the BPA-free plastic most entries on our list were made of. You must be sure that the bottle won’t break or bend after a couple of uses.
Moreover, make sure that the product comes with a warranty so that you can replace missing or broken parts easily.

Traveling Essentials – The Filtered Water Bottle

Why should you carry a water filter when you travel? Well, the answer is simple; you can never know if the places you may find yourself in have clean water or a store from where you can buy bottled water.
Moreover, if you plan on traveling into the wilderness, you clearly need water with you. If you are traveling lightweight, then you won’t need a bunch of water bottles inside your backpack. You need to find other ways to purify water in the wilderness.

If you have a filtered water bottle with you that’s equipped with the right filter, then you can rely on each water source you come across in order to get clean, fresh, and safe to drink water. There are many bacteria and viruses in rivers, streams, lakes, etc., and these can easily send you to the hospital right away. Therefore, it is recommended that you have a filtered water bottle with you. You can carry some highest-quality water purification tablets with you for emergencies, too.

The Ups and Downs of a Filtered Water Bottle

Now that we’ve got the magic behind a filtered water bottle out of the way, we should talk about the pros and cons of water bottles with filters. Naturally, everything comes with its ups and downs. However, the downs apply mostly depending on your preferences and on the desired convenience of the product. Of course, it is still recommended to have a filtered water bottle lying around and use it daily. Remember, not only does it make your water cleaner and healthier, but it also reduces the use of plastic bottles.

The Advantages of a Filtered Water Bottle

This advantage is pretty much straightforward; you won’t have to rely on bottled water anymore when going to the gym or outdoors, for example. A small investment in a filtered water bottle will let you drink tap water and save some money as you won’t need water bottles again.


As mentioned a lot of times so far, the environment is the thing that benefits the most if you use a filtered water bottle. Instead of stocking up weekly on bottled water and then throwing away the plastic bottles, you have to use only one single bottle and enjoy clean water.


If you are traveling and you’re thirsty, but you can’t find any store to buy water from, then you’re pretty much left parched until you come across drinkable water. However, if you have a filtered water bottle, then you can trust almost any source of water you can find; streams, lakes, rivers, and such. Basically, you’ll always have a water bottle with you, no matter where you go.

An Alternative to Classic Filtering Methods

A filtered water bottle renders useless things like disinfection tablets, ultraviolet light, hard pump filters, and boiling. All these methods take up a lot of time and are not as reliable as a filter. For example, if you run out of tablets, you might have a hard time finding some again. Also, ultraviolet lights need batteries, pump filters are bulky, and boiling just can’t be done anywhere.

The Disadvantages of a Filtered Water Bottle


You have to drink through a straw, mainly because it is attached to the filter and not to the whole container of the bottle. Using a straw can make drinking a bit slower. If you are really thirsty and need big gulps, you won’t probably enjoy some products out there.


Most of the entries on our list were made of BPA-free plastic. However, there are filtered water bottles that are made of stainless steel, meaning that they are a bit heavy. If you choose one made of heavier material, make sure that it won’t be a burden to you.

Small Container

Naturally, a filtered water bottle won’t come with a large container. They can usually hold around 20 ounces of water. When it comes to longer hikes, you may not be satisfied with this amount of water and might resort to a couple of water bottles instead. Check out our list of best-selling water storage containers for larger container options.


In terms of purity, the water provided by these items is as pure or even purer as the one found in bottled water. However, it is not as pure when compared to reverse osmosis water.

As you have noticed, the disadvantages depend on your preferences. It’s true that, when it comes to purity, it may not be the purest water out there. A filtered water bottle helps you get tap water to the same level as bottled water and maybe even higher, though.

Frequently Asked Questions

  1. Can the filtered water be stored?
    Yes, you can store the filtered water if you want. Just make sure that the container is not in direct sunlight and you consume the water within one day.
  2. Are filtered water bottles dishwasher safe?

  3. Can a filtered water bottle be put in a fridge or a freezer?
    You can safely put/store your filtered water bottle in the fridge, but you should not put it in the freezer unless you want to replace its filter for no reason. If the filter freezes, its membrane will get damaged and will affect its overall performance.
