Best Filtered Water Bottles

It is very important to make sure that everything you eat and drink must be healthy and good for your body. Instead of drinking carbonated or soft drinks, you should consume plenty of water.

According to health experts, an average person should drink at least 2 liters of water a day.

But nothing can guarantee that the water you drink daily does not contain unwanted chemicals and toxins such as lead, chlorine, giardia, and cryptosporidium.

They are very harmful substances that can increase the risk of gastrointestinal diseases as well as rectal, bladder and colon cancers.

To stay healthy, you can drink bottled water. However, if you drink enough the recommended amount of water a day, you may have to spend a lot of money.

The second solution, which is more feasible, is to buy a water bottle with filters. It looks no different from the regular water bottle; the only difference is that it can remove all chemicals and toxins from the water.

And, if you are not sure which filtered water bottle to buy, here are the best options.

The Magic Behind Your Filtered Water Bottle

Clean water is an essential part of our lives. If you do not drink enough water every day, you are more likely to suffer from headaches, fatigue, digestive problems, and many other dangerous diseases.

According to health experts, you should drink at least 2 liters of water per day. This advice sounds simple, but many people miss out due to forgetting, being busy, or simply not having enough clean water to drink.

If the clean water source in your area is severely lacking, filtered water will be a great solution. It not only helps you keep your body hydrated, but also ensures your drinking water is clean and safe.

While bottled water is quite expensive and not environmentally friendly, why not buy a filtered water bottle?

For those who do not know what it is, the filtered water bottle looks quite similar to regular water bottles. It is also very compact and easy to carry anywhere.

So what is the difference between regular tap water and filtered water, and if you still survive after drinking tap water for so long, why should you buy a filtered water bottle? For most people, the two main benefits are their health and taste.

The difference, as well as the most significant advantages of filtered water bottles, is that they come with a filter which can remove harmful bacteria and toxins.

It can even improve the smell and taste, meaning you can always get fresh and delicious water every time.

If you love backpacking, hiking, or often going to wild places, this product is convenient. It may, in some cases, be your lifesaver.

How The Filtration System Works

You can say that the filtration system is an essential part of a filtered water bottle, which can filter out impurities and toxic substances in tap water.

The filtering mechanism will depend on the structure of each water bottle. Some filter the water when you fill up the bottle while others filter the water when you consume it.

But in general, most water filter bottles use a carbon filter and follow the fundamental mechanism as follows:

a) Activated carbon

Carbon filters use activated carbon to remove impurities from water. If you see the black specks at the bottom of the water bottle, that is activated carbon.

However, regardless of the presence of these black specks, you need to replace the filter regularly to make sure it works best.

That activated carbon has got oxidized, usually through physical degradation and modification in a controlled furnace to become highly porous.

Then, it will increase the ratio of the total surface area per unit of volume and allow the next step of the filtration process to take place easier.

b) Adsorption

Adsorption is the process of attaching ions, atoms, and molecules to the surface due to chemicals.

Activated carbon will open pores to bind those molecules. One gram of activated carbon has about 300 to 2,000 square meters of surface area available for bonding.

The filters will absorb toxins and bacteria in the water. This reaction is precisely how the filtration system works.

By increasing the number of binding positions per volume unit of carbon, activated carbon removes harmful contaminants by binding to them.

Ionized carbon often has four binding sites, a relatively high number among all chemical elements, and that is the reason why it can create an effective filtration system.

c) Filtration

The filtering process takes place when the activated carbon in the filter absorbs all contaminants in the water.

As a result, it will have no room to store bacteria and viruses after a certain amount of water. That is why you need to change the filter regularly.

Depending on each type of filtered water bottle, the replacement time maybe every 2 or 3 months. You need to follow the recommendations from the manufacturers to make your bottle have the best performance.

Filtered Water Bottle: Advantages And Disadvantages


Due to the many outstanding benefits, filtered water bottles are increasingly popular and becoming one of the must-have items in each person’s backpack. Here are some advantages that a filtered water bottle gives us:

a) Save Money

Many people often buy bottled water to ensure drinking water is clean and safe since we are no longer confident to drink water directly from the tap.

When you are on the road and feeling thirsty, you can visit a roadside grocery store and buy some small bottles to drink.

But if you add up the money you spent to buy bottled water, that number may surprise you. Buying bottled water is an expensive solution. Instead, you can get a filtered water bottle to save money.

Each bottle comes with a separate filter – fill it with water, and it will do the rest for you. With this product, you will always have clean water to drink without spending a cent.

b) Protect The Environment

Regular water bottles often take a long time to decompose, affecting the environment severely. Also, it needs a large amount of energy to produce bottles as well as supply and store them before selling.

Meanwhile, a water bottle with a filter, which you can use many times, is a perfect solution to protect the environment.

c) A Great Alternative to Disinfectants

Some people also often use disinfection tablets to disinfect water. They are small and very easy to use. You need to drop some in the water, but the problem here is that you may have to wait a few hours before it dissolves.

Also, if you are going to some wild places, it is hard to find a place to buy it. So having a filtered water bottle is still much better.

d) Convenient

It is convenient if you have a water bottle that can be easily carried and used anywhere. You can use it when you are on the road or traveling to places where drinking water is scarce and away from convenience stores.

The filtered water bottle is easy to use and ensures you will always have enough clean water to drink.


Although there are many advantages, nothing is perfect. The first disadvantage is that you have to drink through a straw. Compared to a typical water bottle, its flow rate is slower. However, this is not too big a problem for most users.

Secondly, most filters are made of stainless steel. It looks beautiful, but it is quite heavy. The titanium bottles would be much lighter ? most of us just like everything handy and lightweight.

A further drawback is that the capacity of most filtered water bottles is quite small. If you are on a long trip, you will need more. They can often contain only about 20 ounces of water, not enough for long trips.

Although there are a few disadvantages, in general, it is still a great product that you should buy.

Filtered Water Bottles For Traveling

Rather than a purchase, having a filtered water bottle is an investment – an investment in health, and the environment. Without it on your trip, you can only get clean and safe drinking water by buying bottled water.

Many people think about boiling water, but that can only kill bacteria but does nothing to remove the toxins in the water. Boiling water can even increase the concentration of chemicals in the water.

Plus, surely no one wants to drink water with a weird taste, but if your body gets dehydrated during the trip, it is an acute problem. You can quickly end up in the hospital because of dehydration or drinking contaminated water.

By all the above reasons, it is essential to have a filtered water bottle while traveling.

Things To Consider Before Buying A Filtered Water Bottle

a) What Do You Want to Filter?

Not all filtered water bottles have the same purpose. If you are on a long trip and plan to get water right from the stream, you will need a water bottle with a strong filtration system like the GRAYL Ultralight Water Purifier or LifeStraw.

However, if you want to improve the quality of drinking water at home, you can choose cheaper water bottles.

Considering your purpose before buying it will help you select the best product for your specific needs.

b) Quality of Material

One of the most important things to consider first is whether your water bottle contains BPA.

After a period of use, a worn-out amount of plastic inside the water bottle will get into your water and then into your body. BPA is a plastic that hurts your health, so you should stay away from it.

If you only use water bottles for a short time, it will not be a serious problem. However, you cannot use them for just one time.

Most users hope it will be their companion for a long time. Therefore, to ensure safety for health, you should buy water bottles that are made of BPA-free materials.

c) Type of Water Filter

There are two types of filters available on the market: activated carbon filter and UV filter.
Most water bottles come with an activated carbon filter because the UV filter is not only more expensive but also needs to be powered by batteries.

UV filters cannot eliminate harmful chemicals in the water, but its ability to remove viruses and disinfect water is better than that of the activated carbon counterpart.

Some water bottles combine both of these filters to give you complete protection against toxins, bacteria, viruses, and parasites. Depending on your needs, you can choose a water bottle with a suitable type.

d) Price

A regular filtered water bottle usually costs from $10 to $30, and even $50, depending on its quality as well as where you buy it.

The best way to determine an affordable water bottle is to find your favorite brand then search the web.

Some online shopping sites like Amazon or Walmart often offer products at a reasonable price and lots of promotions.
