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.
We’ve invested the time so you don’t have to:
In our opinion, the GRAYL Geopress Water Purifier Bottle is the best overall filtered water bottle. This durable water bottle effectively filters the harmful contaminants from the water in a few seconds in a process that only involves filling and pressing the bottle to get clean and filtered water.
The GRAYL Geopress Water Purifier Bottle is really powerful at removing pathogens, using an ion exchange process it can remove 99.9% of viruses, 99.9999% bacteria, and 99.9% of protozoa. But with its activated carbon layer, it also removes other harmful contaminants such as particulates (like sediments, silt, microplastics, etc.), chemicals (like chlorine, benzene, etc.), heavy metals (like lead, arsenic, etc.), and bad taste and odors.
Another feature that we like about this filtered water bottle is that it is independently tested to meet the NSF 42 and 53 standards.
The NSF 42 ensures that it is designed to reduce non-health-related contaminants, such as chlorine, chloramine, taste and odor, iron, manganese, particulate, and total dissolved solids (TDS), and the NSF 53 ensures that it is designed to reduce specific health-related contaminants, such as lead, Cryptosporidium, VOCs, and chromium.
The GRAYL Geopress Water Purifier Bottle has a good capacity of 24 oz (710 mL) and a really quick filtration speed, and it’s able to filter one bottle in 8 seconds, which means it can filter 5L in a minute.
This is done through a special design in which to complete the purification process you just need to fill the bottle and press it, to then be able to drink the clean water. There is no electricity involved, and you don’t need to suck the water through a filtering straw as in other bottles.
The filter of this water bottle lasts for 65 gallons of water (~250 L), which is better than most competitors that only filter between 20 to 40 gallons of water.
- Highly effective against viruses, bacteria, and protozoa
- NSF certified
- Great soft press design that delivers filtered water in a few seconds
- Great filter longevity, up to 65 gallons
- Good capacity of 24 ounces
- Some customers find it difficult to press to filter the water
The LifeStraw Go Water Bottle is our runner-up on the choice for the best filtered water bottle. It is an affordable and lightweight water bottle with 2 stages of filtration capable of removing harmful contaminants, that come with a filter that will last long.
The LifeStraw Go Water Bottle has 2 stages of filtration, the first one in which a membrane microfilter with 0.2 microns removes bacteria, parasites, and microplastics, and the second stage in which an activated carbon filter reduces chlorine, chemicals, bad tastes, and odors.
It is a lightweight filtered water bottle that makes it easy to take anywhere but is also made with resistant materials that will make it last longer, and dishwasher safe.
Regarding the filter longevity, the LifeStraw Go Water Bottle needs to be analyzed from 2 different perspectives. The membrane microfilter filters up to 1.000 gallons, which is an amazing performance compared to other competitors. The activated carbon filter can filter up to 26 gallons, which isn’t that impressive, but this is an optional filter.
One factor that we like about the LifeStraw Go Water Bottle is that for each purchased bottle, LifeStraw offers one year of safe water to a child, so you can make a positive impact in the world with your purchase.
- Filtration capability
- Filter longevity
- Different colors available
- Need to drink using the straw
- Filters only up to 0.2 microns
- Some customers complained about leaks
The Brita Plastic Water Filter Bottle is the best budget choice for a filtered water bottle. It is an affordable and lightweight water filter bottle to use with city water, with a nice design, available in BPA-free plastic and stainless steel, and different colors.
The Brita Plastic Water Filter Bottle uses an activated carbon filter that reduces chlorine, bad tastes and odors. While this is enough to deal with most of the city water sources, we wouldn’t recommend using water sources outdoors, because it won’t remove viruses, bacteria, and parasites, like other filtered water bottles we reviewed.
This water bottle has a nice leak-proof lid design and a push-button lid which is good to keep it clean and avoid contamination. It is also easy to clean and can go to the dishwasher.
The filter longevity of Brita Plastic Water Filter Bottle is around 40 gallons of water, which is not as good as other competitors offer. This should not be a showstopper, as the filters are more affordable than other brands.
And if you are not a fan of plastic bottles, Brita has a stainless steel filtered water bottle option that comes in multiple colors. A nice feature of the stainless steel bottle is the double-wall insulation that will keep the water cold for a long period.
- Dishwasher safe
- Leak-proof lid
- Need to drink using the straw
- Filter longevity
The Larq Water Bottle is one of our favorite filtered water bottles, as this well-designed stainless steel bottle purifies your water in seconds using UV technology and keeps self-cleaning every 2 hours, without the need of changing filters regularly.
The Larq Water Bottle can neutralize 99.9999% of bacteria and viruses from your water with a push of a button, using UV-C light technology. But you should notice that it won’t remove chemicals like chlorine or heavy metals from your water like other filtered water bottles can do.
What differentiates this water bottle from the others is its mechanism to purify water, as you only need to press a button and wait 60 seconds, to get clean and pure water. And it also comes with an intelligent self-cleaning feature that cleans the water for 10 seconds every 2 hours, to ensure that you will always have clean water available.
The Larq Water Bottle is made in stainless steel and has a beautiful design with a double wall to insulate its content, being able to keep the water cool for 24 hours or cold for 12 hours.
With this filtered water bottle you will no longer need to change filters every few months, as the UV filter will last longer, and only needs to be charged once a month.

- No filter replacement required
- Self-cleaning mode

Notice that the manufacturer claims its product was independently tested against these standards but does not mention a certification for these standards.
Another thing that we like about the Epic Nalgene OG Water Filtration Bottle is its flexibility because you can choose from different colors and sizes, and you can also change its filter from the “Everyday Filter”, which is included in the bottle, to a more powerful “Outdoor Adventure Filter”, if you need to use it outdoors with more contaminated water sources.
And the Epic Nalgene OG Water Filtration Bottle comes with a 100% money-back guarantee which shows the trust that the manufacturer has in the high quality of its product.

Another great choice for a filtered water bottle is the SurviMate Filtered Water Bottle. This affordable filtered water bottle has great longevity of 1.500 L and it can remove several harmful contaminants through a 4-stage filtration process.
The SurviMate Filtered Water Bottle removes the most harmful contaminants from the water combining different filtration media, like a hollow fiber UF Membrane, a coconut shell activated carbon, beads, and a medical-grade PP Cotton. Any contaminant or particle with more than 0.01 micron will be removed from the water using these filters.
One of the features that distinguish this filtered water bottle from the competition is its great filter longevity of 1.500L, or around 400 gallons, which is almost 10x of the average of 40 gallons capacity.

The Katadyn BeFree Collapsible Filtered Water Bottle has a 0.1-micron hollow-fiber filter which can remove up to 99.9999% of bacteria, and 99.9% of protozoa (like Giardia and Cryptosporidium) from the water, making it a safe choice to use with outdoor water sources.
Because of its clean and collapsible design, you can store this water bottle in small spaces like your jacket, pocket, or purse, and then fill it with water and drink whenever you need.
The Katadyn BeFree Collapsible Filtered Water Bottle can filter up to 264 gallons of water (1.000 L) which lasts much longer than the average competitors, that will typically filter around 40 gallons of water before needing to replace the filter.
This filtered water bottle is really easy to use and clean. You don’t need to suck the water out of a straw, like most of the competition, as you can just drink normally and get a nice water flow (2L/min). To clean it you only need to shake it to remove sediments or debris, no need for backflushing like other options.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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:
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.
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.
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.
For us, the best overall choice is the GRAYL Geopress Water Purifier Bottle, but all the filtered water bottles we have reviewed in our top are great choices, so you can’t go wrong with any of them!
