The best self-filtering water bottle will keep your water clean, regardless of the situation you find yourself in.

Whether you’re tired of trying to find safe drinking water while exploring the great outdoors or can’t stand the taste of the water that comes out of the communal fountain at your workplace, a self-filtering water bottle will save the day.

But not all self-filtering water bottles are made equal. Some are better at eliminating bacteria than others.

Choosing the best self-filtering water bottle might seem overwhelming. Where do you start?

Why Use a Self-Filtering Water Bottle?

Drinking enough water is crucial for good health. However, if you’re drinking water straight out of the tap, it could be causing you more harm than good.

Tap water sometimes contains chlorine, assorted hormones, fluorine compounds, pesticides, trace amounts of prescription drugs, and hundreds of other contaminants with unknown long-term effects.

For most people, the obvious alternative to tap water is bottled water.

But here’s the thing: Bottled water isn’t necessarily any better. Besides, it’s also incredibly wasteful. Humans purchase about a million plastic bottles a minute. In the U.S, consumers recycle only 23 percent of all plastic bottles.

If you want to boost your health, and save money, and help the environment at the same time, consider investing in the best self-filtering water bottle.

Best of all? You can use self-filtering water bottles for more than just cleaning your tap water!

For example, if you’re into hiking, you can use a self-filtering water bottle to turn lake or river water into drinking water.

Similarly, if you’re off traveling the world, you might find yourself in an exotic country with questionable drinking water. Instead of risking contracting a disease, or spending a small fortune on bottled water, you can use your self-filtering water bottle to remove viruses and other contaminants from the water.

How Does a Self-Filtering Water Bottle Work?

A self-filtering water bottle looks like a regular water bottle. However, unlike ordinary water bottles, self-filtering water bottles use a filtration system.

The micron score measures the effectiveness of most filters. A micron is the millionth part of a meter, or 0.001 mm. So, a water filter that protects you down to one micron gets rid of all particles larger than one micron. Most large bacteria is in the range of 1 to 100 microns.

Some water bottle models come equipped with filters that clean water as soon as you pour it inside the bottle. On the other hand, it’s not unusual to see bottles that filter water when you drink from the bottle instead.

Regardless of the particular system utilized, water typically goes through multiple filters, thus eliminating all, or most, contaminants.

Make it Last

Not even the best self-filtering water bottle will last you forever if you don’t take proper care of it. Always read the instructions manual to see whether you need to take any specific steps to keep your water bottle in good condition.

Keep in mind that while most bottles are dishwasher safe, the filters aren’t.

Changing the Filter

Self-filtering water bottles are a little harder to upkeep than regular water bottles.

Once in a while, you’ll need to replace the filter inside your self-filtering water bottle to ensure water purity.

Generally, a water bottle filter lasts between two to six months, although some models can last you for up to a year. Most models also specify the number of gallons of water that the filter can handle before it needs to be swapped out.

Choosing the Best Self-Filtering Water Bottle

If you want to ensure that you buy the best self-filtering water bottle for you, you need to consider several factors.

Know its purpose

The first step in picking the best self-filtering water bottle is figuring out what you’ll be using it for.

Are you looking to purchase the best self-filtering water bottle because you’re addicted to hiking, but you never bring enough water? Do you worry about the quality of the water that comes out of your tap? Or perhaps you’re about to embark on a backpacking adventure?

If you don’t need intense filtration, you can opt for simpler models that eliminate weird odors and tastes, but little else.

Conversely, if you’re traveling to a third world country, you’ll want to invest in a water bottle that can eliminate waterborne bacteria and viruses.

Material matters

Most self-filtering water bottles are plastic. Nonetheless, you can purchase self-filtering water bottles that are made from other materials, such as glass, too.

Because glass water bottles have no plastic components, they make water taste neutral. However, glass products are usually more expensive than plastic products.

If you’re choosing a plastic water bottle, make sure that it’s free of BPA material. BPA stands for Bisphenol A, a chemical commonly found in plastic that harms your health.

Consider the weight

If you’re purchasing the best self-filtering water bottle to take with you when you run a marathon, you’ll want a model that is as lightweight as possible.

Conversely, if you’re going to use the best self-filtering water bottle at home or work, weight isn’t likely to be as big an issue.

Generally speaking, the more powerful the filtration system, the heavier the water bottle.

The two-stage activated carbon filter, which removes 99.9 percent of waterborne bacteria and parasites, consists of a hollow fiber membrane and a carbon capsule.

The hollow fiber membrane acts as a physical barrier against parasites and bacteria, including E. coli. On the other hand, the carbon capsule improves the taste and reduces bad odor, chlorine, and organic chemical matter such as pesticides.

This bottle is made of BPA-free Tritan and can hold around 19 ounces of water. It’s equipped with a food-grade silicone mouthpiece although you have to suck on it relatively hard to push the water through the filter.

According to GRAYL, the bottle’s filter cleans around 16 ounces of water in just 15 seconds.

The bottle also filters lake, river, and pond water. However, filtrating water isn’t easy as you need to press down on the bottle with a fair bit of strength.

OKO H20 Level-2 Filtration Water Bottle

  • O-ring carabineer used to carry or hook the bottle onto a bag
  • Water bottle with Level-2 filter
  • Filter produces superiorly-efficient filtration with a powerful flow

The OKO H20 Level-2 Filtration Water Bottle uses a two-stage filtration process, which involves a method known as “attraction and retention” to trap contaminants before killing them.

This filtration system eliminates more than 90 percent of bacteria such as E-coli, Cryptosporidium, and Giardia. Furthermore, it can filter water in more than 140 countries.

The FDA-approved plastic bottle features a BPA-free Tritan cap. Because the lid is transparent, you can observe the water filtration process as it happens.

The bottle’s contoured shape makes it easier to grip it whereas the carabineer is useful for hooking the bottle onto your bag.

You can choose between the 22-ounce version and the 34-ounce version. The former weighs around 5 ounces whereas the latter weighs just over 5 ounces. Both have a 100-gallon filter capacity.

The OKO H20 Level-2 Filtration Water Bottle gets a 4.0 out of 5.0-star rating on Amazon. Users said that the bottle is easy to use and noted that the resulting water tastes great.

Nonetheless, some people said that there’s a design flaw: Air gets through into the mouthpiece, which makes the bottle difficult to use.

Seychelle Extreme Water Filter Bottle

  • Chemical pollutants such as detergents, herbicides, and pesticides
  • Inorganic substances such as aluminum, lead, and mercury

  • Aesthetic contaminants such as chlorine, bad taste, and odor

This food-grade water bottle is squeezable, which makes drinking purified water much easier.

Katadyn BeFree Water Filter

  • 0.1 micron water filter removes harmful organisms like bacteria…
  • Collapsible 1.0L hydrapak soft bottle flask packs down small to fit in…
  • Ez-clean Membrane is simple and easy to clean by simply shaking or…

The collapsible Katadyn BeFree Water Filter is, without a doubt, the best self-filtering water bottle for those who are always on the go, whether hiking, camping, or enjoying other outdoor activities.

The 0.1-micron filter eliminates 99.9 percent of bacteria and protozoa found in water, but only if you reside or are traveling in the U.S. or Canada. Since the filter doesn’t get rid of viruses found in other areas, you’d be wise to leave it at home when going abroad.

Even though the bottle is collapsible, it isn’t too tricky to use. It features a wide mouthpiece and is therefore easy to fill, especially with water from large running sources. You might have a difficult time filling the bottle when the water source is small, however.

The 3-liter version weighs just over 3 ounces and can filter up to 264 gallons of water. Katadyn also offers both smaller and larger versions of this product, so you can choose the model that suits your needs and lifestyle best.

The only drawback is that the bottle is very delicate. If you’re not careful, you could end up with a pinhole or a rip.

On Amazon, this water bottle gets a 4.1 out of 5.0-star rating. Customers said that the Katadyn BeFree Water Filter bottle is easy to pack and use. Nonetheless, some users noted that the bottle’s design is flawed. Apparently, the filter is poorly secured.

Escape Glass Filtered Water Bottle

  • PROTECTED GLASS: Protective silicone sleeve provides durability and a…
  • NO HEAVY METALS OR BPS LEACHING: Our glass bottles offer a pure taste…
  • MULTI-STAGE FILTRATION PROCESS: The Escape Glass Filtered Water uses…

The Escape Glass Filtered Water Bottle is another self-filtered water bottle by Epic Water Filters. Because the water bottle is glass, you don’t have to worry about heavy metal or BPS leaching. That’s one of the reasons this water bottle stands out from other products on our best self-filtered water bottle list.

The bottle achieves one-micron contaminant removal via a multi-stage filtration process that includes adsorption and depth filtration.

The coconut carbon-fiber mesh adsorbs chemicals, heavy metals, and pharmaceuticals. Depth filtration removes suspended waste products that try to pass through thousands of layers of the coconut carbon fiber mesh.

Nonetheless, the Escape Glass Filtered Water Bottle doesn’t remove bacteria or viruses. However, if bacteria filtering is important to you, you can always upgrade to a special outdoor microbiological filter designed with freshwater in mind.

The bottle can handle temperature changes and chemical corrosion. Because it comes with a protective silicone wrap, it’s also scratch-, stain-, and impact-resistant.

Also, the Safeguard lid provides a cover that keeps your mouthpiece dust- and debris-free. The straw is removable and thus easy to clean.

The Escape has a 24-ounce capacity. Its filter can handle 75 gallons of water.

The company offers a 100 percent lifetime satisfaction guarantee on all its products. As such, you can send the self-filtering water bottle back if you’re unhappy with it and receive a full refund.
