Bottled water is not always an option, and especially so if you care about the environment and your own health. Packed in single-use plastic bottles, they contain BPA, a chemical linked to type 2 diabetes and even cancer. And we all know what plastic does to the environment. So what one actually needs to do in places where you might not have access to clean drinking water is to carry a compact, small, inexpensive, and easily portable water filter.
Filtered water bottles give you the option of accessing drinking water that is clean, good to taste, BPA-free, and doesn’t create plastic waste. You need to find the best one that not only purifies water but is leak-proof and doesn’t leave an after-taste in your mouth. We hope our review of the 11 best filtered water bottles will help you find the perfect environment-friendly one for your hiking and camping trips.

Now that you have been through our review of the 11 best filtered water bottles, let us tell you what to keep in mind while choosing one for yourself so that you always have clean and pure water wherever you go.
How To Choose The Right Filtered Water Bottle
- Bottle size
Though bottles are available in smaller and bigger sizes, the average capacity is 20 ounces. They are available in sizes ranging between 17 to 34 ounces, so you will have to decide what size is suitable for your requirements and whether that will be enough water for you at one time. It should also fit nicely in your backpack and be convenient to carry. It shouldn’t be so bulky that carrying it becomes a problem.
- Bottle material
The material of the bottle needs to be sturdy and durable, and made of BPA-free plastic so that it’s safe and doesn’t break or bend after a while. Stainless steel bottles are very sturdy and long-lasting but tend to be heavy. Ideally a filtered water bottle should last you for 5 years.
- Type of filter
Most water filter bottles come equipped with a carbon activated filter to trap impurities and contaminants in the filter media. Others feature a UV filter which needs batteries and also tends to be more expensive. They are chemical-free and effectively remove viruses, but do not remove chemical compounds like fluoride and chlorine at all. Some filtered water bottles feature a combination of carbon-activated and UV filters which are extremely effective, but again tend to be more expensive.
- What you want filtered out
Not all water bottles can filter out the same contaminants— they usually filter out chemicals like fluoride, chlorine, and copper, reduce odor, and improve its taste. If you are drinking from a river or stream, it’s best to get one that filters bacteria, parasites, and viruses from water. For outdoor activities like hiking and camping, you need a bottle that filters protozoan, bacteria, and viruses to avoid intestinal infections. A simple carbon filter is adequate for filtering tap water at home.
- Easily to clean
Some filtered water bottles are easier to clean than others and some are safe to put in the dishwasher as well. Check out reviews of the product to see if anyone has faced hygiene or cleaning issues with the bottle.
- Leak-free design
This is essential if you don’t want water all over yourself and the equipment you are carrying. Though most bottles are advertised as leak-proof, this may not be the case once they are turned upside down.
- Filter lifespan
All filters need to be replaced after it has filtered a certain volume of water. In some cases, it can be 40 gallons while others may last through hundreds of gallons before they have to be replaced. Having to change the filter too frequently can be a hassle, irksome, and also expensive. So you should go for a filter that will last as long as possible for your convenience and to be budget-friendly.
Now that you know how to choose the best filtered water bottle, you should also be aware of the different types that are available. This is information that you should have before you decide on the bottle that you will buy. So here are the different types of filtered water bottles that you can choose from.
Types Of Filtered Water Bottles
- Straw filter
These bottles are extremely lightweight, compact, easy to carry and use, and come equipped with a straw encased in a protective covering. The water gets filtered as you suck it up through the straw. Since the filter is in the straw, you can draw up water from a river or pool very easily. The only drawback is that you have to kneel down to the level of the water and it requires some effort to suck up the water.
- Gravity filter
These filters work on the principle of gravity where the unclean water is stored in a reservoir and placed above a water tank. The dirty water flows down because of gravity, passes through the filter, and collects in the water tank. It’s good for both solo use and for a group, the only drawback being that it’s time consuming and slow and can’t be used on the go.
- The squeeze filter
These are very similar to the gravity filters except that muscle power is used instead of gravity. The water reservoir has to be squeezed so that the water is pushed through the filter. Some squeeze filters come with their own small reservoir, but they can be used with a disposable water bottle as well.
- The pump filter
These remove impurities from water that is drawn from the source with the help of a manual pump. They are like small hand pumps that are fitted with filters and remove the impurities of the water as it passes through it. Though very good at filtering water, the pumping can get tiring.
Frequently Asked Questions
- How long can I store my filtered water for?
It can be stored in the fridge for up to 24 hours, but be careful to avoid hot areas and direct sunlight. It can be kept out of the fridge all day if you are drinking from it constantly, and for a few hours at a stretch if you are not using it.
- Can I put my water bottle in a freezer?
No, you shouldn’t do that as the membrane of the filter gets damaged when the filter freezes. This affects the efficiency of the filter and makes it useless.
- How do I know if my water bottle is dishwasher safe?
This will usually be mentioned in the product description so you should just follow the guidelines of the manufacturer, but most of them are dishwasher-safe. But do remember to remove the filter before placing the bottle in the dishwasher and follow specific instructions like it may be recommended to place the bottle in the top shelf. The filter can be cleaned separately under running water.
- Can a filtered water bottle make river water safe for drinking?
It depends on the filter of the bottle that you buy. Some filters only remove chemicals like chlorine while others can remove the bacteria and viruses found in river water. If you are planning to carry it while hiking or camping, you need to buy one that is designed for filtering river water.
- If I don’t use my filter every day, will it dry out?
No, that is not going to happen. It doesn’t make a difference whether you use it every day or not.
- How do I know when it’s time to change my filter?
It’s not always possible to tell, but it’s best to change it after 2 months of use. If the flow of the water through the filter slows down, it means the filter is getting clogged. Sometimes, the taste of the water also changes or it may not be as clear as before.
- Why is no water coming out of my straw?
The first thing is to check whether you are using it the way it’s mentioned in the user manual of the bottle. Some are designed to hold below your mouth before sucking through the straw while others require you to tilt your head back while holding the bottle almost upside down. Sometimes, when the filter is clogged or damaged, it may slow down or stop the flow of water.
Finding clean drinking water can be a real issue when you are out backpacking, hiking, or camping. And we are all aware that plastic bottled water shouldn’t really be an option, what with BPA, and choking the environment. Filtered water bottles provide you with clean and odorless drinking water wherever you go, and the best part is that they are easily portable, inexpensive, compact, and a great alternative to bottled water. Just fill up water from any source and the filtered water bottle will take care of the rest, so it’s time to choose. We hope our review of the 11 best filtered water bottles will make your job of choosing the best one extremely simple and convenient.
