10 Best Filtered Water Bottles Reviewed

After investing our time researching and reviewing several filtered water bottles, we identified the 10 best options for different purposes.

Buying Guide for Filtered Water Bottle

With so many options available, it is not an easy task to choose the right filtered water bottle for you.

With that in mind, we present a curated selection of filtered water bottles for different situations, and we also created a comprehensive buying guide for filtered water bottles so that you can understand the most important factors and be able to make the best buying decision.

What to Consider When Choosing the Best Filtered Water Bottle

When researching for a water filter bottle to buy, these are the key features that you should consider:

Capacity & Size

A filtered water bottle range typically is between 17 to 34 ounces (0.5 to 1 liter), so depending on the intended use, the capacity and size of the bottle is a factor to take into consideration.

A smaller filtered water bottle will be lighter but will have less water, which might need frequent refills. A larger bottle will be heavier but will have more water, so plan first when and how you want to use it, and choose accordingly.

Also, the size if you want to store it in a backpack, make sure first it will fit.

Material

There are mainly two types of materials when it comes to filtered water bottles: plastic and stainless steel (you might find some glass bottles, but we don’t recommend them).

If you prefer plastic filtered water bottles, look for BPA-free plastic bottles to avoid harmful chemicals to your health, and that look strong so that they won’t break easily.

One of the key advantages of plastic bottles is that they are lightweight, and one of the disadvantages of plastic filtered water bottles is that they are not good at keeping the water cool.

If the weight is not an issue for you, a stainless steel water filter bottle might be a better choice. They will last longer and will be able to maintain the water cooler.

Cost

While filtered water bottles are not terribly expensive, some models cost multiples times the price of others.

With this we are not saying to go for the less expensive, we just want to alert you to check with features you need and select one that makes sense for you but that also fits your budget.

You also need to take into account the cost of changing the filters, because this recurring cost will add up to the initial cost of buying the filtered water bottle.

Filter longevity

As mentioned when we discussed cost, you will need to change the filter of your water bottle from time to time, so it is important to understand the expected filter longevity of the filtered water bottle that you are purchasing.

It might be better to pay more for a high-quality bottle with filters that last longer because, in the long run, you will be saving money.

Contaminants Removed

Another relevant factor to consider when buying a filtered water bottle is which contaminants it can remove.

If you plan to use it to filter your tap water, you probably only need a bottle that can filter chlorine, sediments, heavy metals, etc., unless your water source is particularly contaminated.

If you plan to go outside and refill it with water from outdoors, it is probably better to buy a filtered water bottle capable of dealing with bacteria, viruses, microorganisms, and pesticides.

Cleanup

You will need to clean up your filtered water bottle frequently, so it is important to understand how easy it is to clean the bottle you choose.

Some bottles are dishwasher safe, which makes it more convenient to clean, but not all are.

What is a Filtered Water Bottle?

A filtered water bottle is a water bottle with an in-built filter to ensure that you drink filtered and clean water.

A filtered water bottle or water purifier bottle is portable, which means that you can have access to purified water outside of your house.

Filtered water bottles are better than regular water bottles because they will last longer and will remove impurities and contaminants that might be in your water.

How Does a Filtered Water Bottle Work?

A filtered water bottle has an in-built filter that will remove contaminants from the water before you drink.

There are two main methods of filtering the water, when it enters the bottle (filter when filling the bottle) or when it leaves the bottle (filter when you drink from the bottle).

But both methods work the same way, the water passes through the filter media which will remove the impurities from it.

The most common filter type in filtered water bottles is activated carbon, which uses its surface area to bind contaminants to it. When it becomes clogged with contaminants won’t be able to trap more, so you will need to change the filter.

There are also water bottles with UV filters that are particularly effective to deal with viruses and bacteria.

Which Contaminants Are Removed by Filtered Water Bottles?

Water filter bottles usually are able to remove the following contaminants:

• Chemicals: Common chemicals found in water are chlorine, chloramines, fluoride, etc.
• Heavy metals: some of the most common metals found in water sources are arsenic, lead, cadmium, nickel, mercury, etc.
• Viruses
• Bacteria

Filtered Water Bottle Benefits

There are several advantages when using a filtered water bottle, such as:

Removes Contaminants & Impurities from Your Water

If you use a filtered water bottle you can be sure that you will be drinking clean water, wherever is used to filter tap water, or if it is used outdoors to filter water from rivers or other water sources that might be contaminated.

Cost

If you currently drink bottled water, buying a filtered water bottle will save you lots of money.

For a small initial investment, you can filter your tap water and drink clean and fresh water at a fraction of the cost of drinking bottled water. Even when you consider the recurring cost of changing the filter, it is much less expensive than drinking bottled water every day.

And even comparing with other water filter types (which are more economical to use than drinking bottled water) like undersink water filters or countertop water filters, a filtered water bottle is less expensive.

Portability & Size

A filtered water bottle has small size, so you can carry it almost anywhere. You can put it in a purse, bag, or backpack and use it at the gym, for work, for a walk, or to go on holiday.

Even if you have a whole house water filter that gives you clean water at home, sometimes you need pure water on the go, and a filtered water bottle is a great option for that, and you can have access to a portable filtering device anywhere you decide to go.

Environment-friendly

Drinking bottled water is not an environmentally friendly option, as the plastic from the bottles isn’t recyclable.

So, using a filtered water bottle is a great alternative because you will still have access to tasty, fresh, and clean water in a bottle, but without producing huge amounts of plastic that will damage our environment.

Hydration

Being properly hydrated is really important for us, and filtered water bottles are great because if you use one of them you will have access to clean water on the go, ensuring that you are never thirsty.

Filtered Water Bottle Disadvantages

But there are a few disadvantages of water filter bottles to filter your water, such as:

Low Capacity

Unlike other water filter types, like water filter pitchers or faucet water filters, the quantity of water that a filtered water bottle can purify at a time is low, because it is limited by the small size of the bottle.

Filtration Power

While filtered water bottles are good at removing contaminants from the water, they are not as powerful as other types of water filters like whole house water filters or Reverse Osmosis systems.

These powerful filtration systems can combine multiple filtration stages to remove several types of contaminants from the water, and some can remove up to 99.9% of the contaminants.

You Will Drink From a Straw

In most of the filtered water bottles, you will have to drink from a straw, as it is typically attached to the filter.

For some people, this can be an inconvenience as not everyone likes to drink this way, so if this is a problem for you make sure you choose a model without this design.

Filtered Water Bottle Maintenance

Filtered water bottles are easy to maintain, but there are a few things that you need to consider.

First, you will need to change the filter every few months, depending on the filter longevity and its usage. This will avoid the filter to clog and ensure that it will continue to function properly, to give you clean water on the go.

Secondly, you should clean your bottle regularly. To do this, start by separating the different components: bottle, lid, straw, filter.

Then, if your filter water bottle is dishwasher safe you can use your dishwasher to clean the allowed components, if not, simply use warm and soapy water to clean the bottle.

Regularly cleaning your filtered water bottle is important to prevent the bacteria from developing in it.

FAQ About Filtered Water Bottles

Here are some answers to frequently asked questions about filtered water bottles.

How do I know when it’s time to change my filter?

Ideally, you should track when you started using the filter, and depending on its advertised duration (typically around 2 months), change it for a new one.

But if you are like me and forget to keep track of these things, there are a few signs that will tell you that the filter of your bottle needs to be changed.

If the water starts to taste different from before, it’s probably a sign that your filter is not working properly.

Another sign is if the water stops flowing as well as before when you are drinking it. In this case, the filter should be already clogged with contaminants and impurities, and it’s time to change it.

Are water filtered bottles safe?

Yes! The best filtered water bottles are made of good materials that won’t be harmful to you.

And they will filter harmful contaminants from the water that could have negative effects on your health.

But you need to consider which contaminants your filtered water bottle removes, and which contaminants your water source has. Make sure that when you buy a filtered water bottle you choose one that can deal with the contaminants in your water source.

Are filtered water bottles dishwasher safe?

Typical yes, but it depends, some are, some aren’t. If this is important to you, check the instructions from the manufacturer before you buy to confirm if the filtered water bottle you want is dishwasher safe or not.

Are filtered water bottles refrigerator-safe?

Yes, you can store your filtered water bottle in the refrigerator.

Just don’t use the freezer, as it can damage the in-built filter.

Do filtered water bottles filter out beneficial minerals?

No, filtered water bottles will remove harmful contaminants from your water, but not the beneficial minerals in it.

Each bottle will target different contaminants, so check first to understand which components are removed with your filtered water bottle.

Why is no water coming out of my straw?

If water is not flowing from the straw of your filtered water bottle, that is a sign that it is time to change the filter, because it is probably clogged with contaminants and impurities.

Another possible reason is that some bottles are designed for sucking out the water from the straw instead of the water flowing freely from it.

Our Verdict

Having access to clean and pure water is a must, and you should be able to drink clean water anywhere. That is why having a good filtered water bottle is so important, because you will be able to drink quality water on the go, and in any place you want.

And with so many different options available it is not easy to make a choice, but after reading our buying guide you should know by now the most important factors to consider when choosing.
