Top 8 Best Filtered Water Bottle Reviews 2020


Clean drinking water is a necessity that isn’t always available during your travels, or even sometimes at home.

Granted, it’s much more important to filter water coming from streams or other natural water sources, but even tap water should be filtered at least slightly before consuming.

So, whether you’re planning for a camping trip, or you’re through with public fountains, we’re going to breakdown the best-filtered water bottle for you.

GRAYL Geopress 24 oz Water Purifier

Larger than most filtered bottles, The GRAYL Geopress is designed to filter all pathogens from any freshwater source you may come across. Through strawless filtration, the bottle can filter up to 5 liters per minute.

In a test done by the company, this GRAYL bottle filtered 99.99% of viruses, 99.9999% of bacteria, and 99.9% of protozoa. The Geopress also filters particulates, chemicals, and heavy metals. On top of filtering contaminants, the Geopress also removes any residual taste or odor from your drinking water.

You can find the Geopress in 4 different unique colors, all made from polypropylene #5, food-grade silicone, TPE, and ABS food-grade plastic.

Here’s how it works:

Each Geopress bottle has an outer refill sleeve that separates from the rest of the bottle and can be filled like a cup. The inner bottle component features a replaceable filter at the bottom to be pressed into the sleeve.

GRAYL utilizes an electro absorptive filter that attracts and captures inorganic pathogens like a magnet.

No more than eight seconds later, you have 24 oz of clean drinking water.

A few features of the Geopress include rubber gripping on the sides of the bottle and along the cap for more comfortable pressing.

A ½ turn of the cap will expose a small vent that is designed to let out air while filtering your water.

You can expect the replaceable Geopress filter to last for 350 presses, which equals 65 gallons. For prepping, an unused geopress filter should last for 10 years on the shelf.

GRAYL also offers a 10-year warranty to their products, covering workmanship and materials.

GRAYL Ultralight Water Purifier

GRAYL has created a bottle that can filter any freshwater source from fountains to streams. The Ultralight is a 16 OZ bottle made from polypropylene #5, food-grade silicone, TPE, and ABS food-grade plastic.

This bottle is capable of removing 99.99% of waterborne pathogens, 99% of lead, and even removes the smell and taste of your water. GRAYL also comes with a 10-year warranty covering workmanship and materials.

How it works:

To begin filtering, simply press the button on top of the bottle. After 15 seconds, the Ultralight will be completely filtered, regardless of the water source. Per-minute, this bottle can filter 2 liters of water.

One filter from the Ultralight can clean enough water to fill 300 standard plastic water bottles before needing to be replaced — which could save you hundreds of dollars when compared to the price of disposable water bottles.

LifeStraw Go Filter Water Bottle

The LifeStraw filters water as you drink, using a filtered straw to clean 99.99% of waterborne contaminants such as bacteria, parasites, and microplastics.

This bottle also removes any remaining taste or smell from your drinking water as it filters. A single replaceable straw can filter up to 4,000 liters, or 1,000 gallons of water from any freshwater source.

The bottle itself is a 23-ounce container made from Triton plastic. LifeStraw is dishwasher safe, aside from the straw filter itself, and is entirely leak-free.

Made from food-grade silicone, the mouthpiece has a hinge to fold in and out when you want to drink.

You can find LifeStraw in over 10 different colors and designs, each with a loop for any clip or carabiner.

On top of the environmental benefits of using a reusable bottle, LifeStraw also provides one child with one schoolyear of drinking water in places that clean water isn’t available.

Lastly, LifeStraw Go can filter any freshwater source, but cannot filter ocean water, or other saltwater sources.

Brita Premium Water Filter Bottle

The Brita bottle is another water bottle that filters as you drink. We really like this one because we found it does a great job of removing the chlorine water taste found in tap water.

This versatile water bottle is small enough to fit in a car cup holder, but large enough to take to the gym or outdoors and stay hydrated. We love this premium water bottle for it’s sleek design.

What’s more, one water bottle filter can replace up to 300 standard 16 ounce bottles! It’s an incredibly effective way to stay environmentally-friendly.

Of course, this bottle is also made with BPA-free plastic and contains a built-in carrying loop that makes it easy to attach to backpacks and belts.

You also have the ability to wash this bottle in the top rack of your dishwasher, which is awesome!

Bobble Classic Water Bottle

The Bobble Water Bottle is designed for much more causal filtration than some others featured here.

This bottle is mostly designed to filter the taste and smell of chlorine in standard tap or fountain water. This is a great choice if you’re looking for a fresher taste for easier hydration, but the Bobble isn’t designed for survival-type scenarios like having to filter pond or river water.

The Bobble bottle is made of BPA-free plastic and is available in 7 colors and two sizes: 18.5 and 32 ounces. A larger bottle can be great for leaving staying hydrated after leaving for a few hours.

One replaceable filter in this bottle filters just over 5,000 ounces of water. Bobble recommends that you handwash this bottle, as opposed to using a dishwasher.

Refresh2go Curve Filtered Water Bottle

Available in six different colors, the Refresh2go is made from durable BPA-free Eastman triton plastic and can hold up to 26 ounces. The curved grip provides an ergonomic grip, and the bottle itself fits into most cupholders.

As for the filter, this bottle features a straw that treats water. Mostly, the filter here is for clearing the taste and odor of chlorine from tap and fountain water which can be very helpful with staying hydrated for people with sensitivity to that chemical taste and smell.

The provided straw is removable, leaving you with the option of filtering your water or drinking it straight.
Using the straw, you can filter up to 40 gallons before replacing, and an extra is provided with the purchase.

Lastly, the Refresh2go is a top-rack dishwasher-safe bottle and has a foldable mouthpiece to stay clean.

Overall, this bottle is a great alternative to disposable bottles or drinking straight from the tap or a fountain, but shouldn’t be used in a survival situation when you need to drink questionable water.

OKO H2O Advanced Filtration Water Bottle

oko water bottleAvailable in three colors (Actric, Charcoal, Moss) and two sizes  (650 ml, 1000 ml).

The OKO H2O Filtration Bottle is a strawless bottle designed to eliminate bacteria, microplastics, and other tiny contaminants.

In a test, the OKO 2-stage filter removed over 99% of bacteria. Although the filter itself has a pore size of 2 microns, it utilizes a positively charged electro-adsorption (attraction and retention) process that can trap bacteria the size of a single pore.

In other words, this bottle has an extremely meticulous filter — but it doesn’t end there. The OKO filter utilizes silver-ions to kill bacteria after it has been trapped; this can be a relief when you’re nearing the recommended time to replace the filter.

An ergonomically contoured grip makes it a bit easier to hold and squeeze while drinking. The OKO is a bit top-heavy when empty, but is well balanced when full of water.

The cap of this bottle is made from triton clear hard plastic. The translucent cap allows you to watch as the bottle filters your water. The OKO also comes with an o-ring carabiner to latch onto things throughout the day.

As a fun fact, the OKO was originally designed for NASA space stations!

SurviMate Water Filter Bottle

survimateThe Survimate Water Bottle is the ultimate filtration system for any freshwater source.

Specially designed to filter bacteria and waterborne contaminants, you can use the Survimate in ponds, puddles, lakes, rivers, and any other freshwater source.

This bottle can hold 22 ounces of water and is made of food-safe copolyester triton plastic, which is highly durable for plastic but still lightweight.

You can expect this filter to last up to 1500 liters, but this number really depends on the quality of water that passes through.

Using a 4-stage filtration system, the Survimate is more thorough than many other filtration bottles. However, this same 4-stage system has one set-back: it can be very difficult to sip. The vendor recommends that you take a few dry sips to get the water through the system, after which you’ll have continuous water for later.

You can find the Survimate in blue or black.

Thermos Water Filtration Bottle

This Thermos bottle can filter class V contaminants, as well as chlorine, microplastics, and bacteria from all freshwater sources.

Although this bottle relies on a straw-system, it is known for being very easy to drink through and won’t require the same force needed to sip other bottles.

The 22-ounce Thermos Filtered Bottle can filter 128 bottle refills, which equals 20 gallons, before needing to be replaced. Both the bottle itself and the filter/lid are completely dishwasher-safe as well.

This filtered bottle is available in 5 different colors, one of which is actually a stainless steel model which is significantly more durable and is great for insulating hot or cold liquid.

The main problem that I’ve found with this bottle is that the plastic models have been known to break and crack easily— I’d personally opt for the steel model!


At the end of the day, the type of filtered bottle that you need comes down to a few variables.

The level of filtration that you need. Going for a jog and filling up at the local drinking fountain is very different from going on a survival camp-out and needing to filter from a stream or other natural sources.

The level of filtration you need will no doubt affect the price, too — but never skimp out on a filter if you might drink unsanitary water. Spending a bit extra to eliminate at least 99% of bacteria is much better than chancing getting sick from something like E-Coli.

  • Do you prefer to have a straw, or are you better off without? There are plenty of options for either, but you don’t want to be stuck sucking through a straw when you’re not a fan.
  • The bottle’s durability. It’s always nice to have something that holds up, but some people need even better durability for what they do. If you’re prone to dropping things, or if you find yourself in environments that might destroy plastic, you should opt for a metal design.
  • Carabiner option. If you’re like me, I always search for the bottle with a ring for hooking up a carabiner. Having the option to carry the bottle hands-free this way has always proved worth-it in my opinion, even more so than fitting into a cupholder.
  • The length of time/amount of water that you’ll need for filtering. If you’re planning to go off of the grid for a few months at a time, you could buy a ton of filters, but it’d be easier and cheaper to invest in a filter that will hold up for at least a hundred gallons.

Just remember, whatever you do, get your favorite color!
