How Do Filtered Water Bottles Work?
When you first hear about filtered water bottles, you might think they’re going to be heavy and large. However, filtered water bottles were made to be taken wherever you go and come in various sizes, depending on capacity.
Inside each bottle is a filtration system. Which method the individual bottles utilizes depends on the filter. Some water bottles filter the water as you fill it, while others filter it as you drink. Each method is effective, so it depends on your preferences.
Filtered water bottles will remove contaminants as well as impurities from the water. Some filters will even remove odors, leaving you with clean, fresh water. What contaminants the bottle removes depends on the filter.
The most common filter is activated carbon, which typically uses three stages of filtration. Let’s take a more detailed look.
Stage #1: Activated Carbon
Activated carbon filters are some of the most commonly used filters. They’re very effective, removing particles ranging in size from 0.5 to 50 microns.
Activated carbon filters can remove a range of contaminants, including sediment, chlorine, volatile organic compounds (VOCs) and odors. In activated carbon filtered water bottles, you may notice tiny black specks at the bottom of the bottle. The specks are perfectly safe and are only escaped carbon.
On the other hand, activated carbon is less effective at removing minerals, salts and other dissolved organic compounds. They also don’t last for long before needing to be replaced. It’s crucial to replace the water filter when required, or else it could begin to leak contaminants back into the water.
The carbon in the filter has been treated with oxygen. This happens via physical modification and degradation in a furnace and makes the carbon highly porous (1). The activated carbon has to be permeable to allow the next step in the process: adsorption.
Stage #2: Adsorption
Adsorption is a simple process where pollutant molecules are trapped inside the pores of the carbon substrate. In a filtered water bottle, the filter removes contaminants by binding to them. Activated carbon is so effective because it generally has four binding sites (2).
Contaminants in the water adsorb to the activated carbon filter because they’re attracted to the carbon atoms. This is why it’s so important to replace the filter when needed. When the carbon becomes fully saturated with pollutants, it can’t catch any more inside its pores.
Stage #3: Filtration
Activated carbon removes pollutants based on its chemical attraction to carbon. Neutral or nonpolar (hydrophobic) contaminants are organic and have a high molecular weight. Consequently, these are easily removed by the filter.
On the other hand, minerals and salts won’t be removed by carbon filters (3).
Pros & Cons of Filtered Water Bottles
Having a filtered water bottle comes with many benefits. Consequently, these types of water bottles have become very popular with active people as well as mommies on the go.
Plastic water bottles are used once or maybe twice, but will eventually end up in landfills. There, they’ll pollute the earth and not degrade. That’s not to mention the time, energy and delivery costs it takes to produce plastic bottled water.
Because of this, many people opt for reusable water bottles, which are enhanced when they have a filter. You get to use the same bottle every day, only changing the filter when needed.
Having your filtered water bottle on hand is very convenient. Maybe you like to go hiking but hate having to bring gallons of water along. Easily fill the bottle in a creek or river along the track.
People who travel often might be wary about the water they’re drinking. The filter will ensure you have pure water to drink outdoors.
Because there’s so much worry about the water coming from our taps, we often opt for bottled water. However, with a filtered water bottle, you won’t have to spend money on expensive bottled water. It’s perfectly safe to fill the bottle with tap water since the filter will remove harmful contaminants.
Better Alternative to Other Methods
Disinfection tablets, hand pump filters, ultraviolet lights and boiling water. These methods are all effective, but not as convenient or not always possible. Filtered water bottles are easy to carry, effective and filter water right then and there.
Slow Water Output
Unlike regular water bottles, where the water seems to just flow out as you drink, filtered bottles are different. Most use a straw, so as you take a sip, the water runs through the filter before exiting the spout or straw.
Consequently, this can slow the process down as the water runs through the filter. But keep at it — as soon as the filter is “broken in,” the water will begin to pick up the pace.
Due to the added filter, the capacity of filtered water bottles can be restricted. Most bottles hold around 20 ounces, which may not be enough for long hikes. However, you do have the option of filling it on the way if you stumble upon a river, lake or creek.
How to Choose (Buying Guide)
Filtered water bottles are convenient and easy on the environment. However, it’s important to find the best filtered bottle that suits your needs and lifestyle. Below, we’ve made a list of a few important points to consider before settling on a bottle.
On average, filtered water bottles will hold around 20 ounces; however, some will only hold around 16. Consider your lifestyle and which capacity will suit you the most.
For instance, if you’re often out on long hikes, a larger capacity of 25 ounces and more will be handy. On the other hand, if you only need a bottle to keep with you as you run errands during the day, a smaller capacity will suffice.
Mind The Weight
Material plays an important role in any high-quality bottle. There are many materials available, most commonly plastic and stainless steel. It’s crucial to choose BPA-free plastic bottles that are FDA-approved to ensure safety (4). The mouthpiece is another crucial point — this should be made out of food-grade silicone.
What Do You Need It to Filter?
Water, you might be thinking. Although this is obvious, it’s important to consider where you might be filling your bottle.
Different water sources hold different contaminants. For instance, parasites and bacteria are found in rivers and creeks, while chemicals are found in tap water (5).
If you’re often out hiking and like to take a sip from any water source, a filter that removes parasites is essential. On the other hand, if you’re only going to drink tap water, a simple filter will suffice.
We searched through the top-rated models and consulted industry experts. We also took into account bottles that can suit any lifestyle while also removing harmful pollutants and being easy to take on-the-go. It’s time to see our recommended best filtered water bottles.

How Long Does the Filter Last?
Most filters will last for up to 40 gallons of water, which is about 5,120 ounces. Depending on usage, it might last you one or two months. It’s crucial to replace the filter before you hit the 40-gallon mark to ensure it’s still safe.
Keep In Mind
Are Filtered Water Bottles Dishwasher Safe?
Whether or not your filtered water bottle is dishwasher safe depends on the material. Common materials include stainless steel, titanium and plastic. Before putting your bottle in the dishwasher, make sure you read the manual to see if it’s safe.
Most dishwasher-safe bottles will be washed on the top shelf — make sure you remove the filter beforehand. We highly recommend choosing a dishwasher-safe bottle. This will be much more convenient for you, especially if you use it daily.
How Do I Clean It?
If your bottle isn’t dishwasher-safe, don’t fret. They’re easy to clean by hand. All you have to do is take the bottle apart and wash it in warm, soapy water. Use a long-handled brush to scrub the inside of the bottle and a sponge for the lid and mouthpiece.
Will the Filter Remove Important Minerals from My Water?
Because most bottles are equipped with an activated carbon filter, they won’t remove minerals.
Activated carbon is designed to remove harmful contaminants such as chlorine and VOCs, but they won’t affect salt or minerals. As a result, you can continue to enjoy purified water rich in minerals that keep your body happy and healthy.
Filtered water bottles are super handy for anyone who enjoys clean water wherever they go.
Most bottles are equipped with an activated carbon filter that can remove chemicals and VOCs. They work by filtering the water as you’re drinking, which can cause the water to run slowly through the straw.
When finding the best filtered water bottle for you, we recommend that you consider where it will be used. You should also consider which capacity will suit you and your needs the best.
Where possible, think how long you’ll be out on a trip and go for a bottle with enough capacity to last that length of time. Doing so will prevent you from running out of high-quality, filtered water.
