Quick Picks for the Best Filtered Water Bottle 2020


Our Research


Our Picks for the Best Filter Water Bottle

To help our readers select the best filter bottle for their needs, we narrowed it down to 3 top picks:


Top Overall: LifeStraw Go

LifeStraw Go

Key Features: 2-stage filtration; best-seller; removes bacteria, protozoa, microplastics and more; affordable

Price Range: $$

See Deal

The LifeStraw Go is one of the most popular options, and our pick for the best filtered water bottle overall. It strikes a great middle ground between price and features. It’s cheaper than the GRAYL (our “premium” recommendation), but nearly as effective and about the same size/weight.

The LifeStraw Go is a filtering water bottle from the company behind the now-famous LifeStraw. Basically, this filter works via your own mouth suction pulling the water up through the filter. You just fill up the water bottle, and suck through the straw to pull the water through the activated carbon and advanced hollow fiber membrane filters to purify the water.

This product is safe to use on most freshwater sources. It removes 99.9999% of waterborne bacteria, 99.9% of protozoan parasites, and 99.999% of microplastics. It’s a best-seller on Amazon and elsewhere. In filtered water bottle reviews, the LifeStraw earns good ratings, although some complain of leaking issues.

One thing to note: because of the straw filter design, this bottle is not suitable for filtering cooking water. For this purpose, we recommend the GRAYL Ultralight, or a good portable water filter.


Budget-Friendly: Brita Sport

Brita SportKey Features: Basic filter; NOT safe for contaminated water; improves taste of potable drinking water; budget-friendly

Price Range: $

See Deal

The Brita Sport water bottle with filter is a good basic option. Important to note: this bottle is not intended to filter stream water, or tap water in areas with unsafe drinking water. Instead, it’s just meant to improve the flavor of already-safe drinking water. Do NOT use this to filter tap water in foreign countries with bad water quality, or to use in backcountry hiking.

With that said, if you’re just looking for a way to improve the taste of tap water, this is a good solution. It’s made by Brita, the leader in home water filters (best-known for their filtered pitchers). This comes as a two-pack of these affordable filter water bottles, and can make a great choice for some situations. The basic filters last for around 40 gallons, so a single bottle could theoretically replace up to 300 standard bottled waters.

Luxury: Grayl Ultralight

Grayl Ultralight

Key Features: Advanced water purification and filtration; effectively removes viruses, bacteria, protozoa and more; easy to use; excellent reviews

Price Range: $$$

See Deal

The GRAYL Ultralight Water Purifier is one of the best filtered water bottles on the market. In fact, it offers more than just filtration, as it is a true water purifier. It effectively removes 99.9999% of viruses, 99.9999% of bacteria, and 99.999% of protozoa. It also reduces particulates, heavy metals, chemicals like chlorine, and more! This bottle is safe to use on virtually any source of fresh water, be it a tap, a stream, or even a freshwater lake.

The GRAYL is very popular amongst international travelers, because it makes tap water in foreign countries safe to drink. It’s also very popular among hikers, who enjoy being able to drink from backcountry streams and rivers. It’s also fairly small and lightweight, so even backpackers can easily use this as their primary water source in the backcountry.

The GRAYL is very easy to use, and uses a patented design. Basically you just fill it up, and press down firmly for 10-15 seconds. That’s it – now you can drink directly from the bottle, or pour it out to use for cooking and washing. It’s that easy!

Benefits of Filtered Water Bottles

The best filter water bottle can help keep you safe, save you a lot of time and money, and help protect the environment! Here are some benefits:

Safety – If you get a high-end filtered water bottle like the GRAYL or LifeStraw Go, you can rest assured that you’re drinking clean, safe water – even if the water source you have access to is questionable. These advanced filters are capable of turning potentially dangerous water – from backcountry streams, or areas with dangerous tap water – into perfectly safe water!

Taste – Filtered water also just tends to taste better. Even if you have access to potable drinking water, it may have an unpleasant taste. The best filtered water bottle can help!

Environmental Impact – Drinking bottled water may be convenient, but it can have some seriously harmful effects on the environment we all share. Not to mention, bottled water is expensive when you drink it frequently!

International Travel – Do you like to travel the world? If so, you’re probably aware that many countries do not have safe drinking water from the tap. You may take it for granted at home, but access to potable drinking water is far from guaranteed in many areas of the world. A lightweight water bottle with filter could be the perfect travel companion!


How We Chose 

There are a lot of competing products out there – how did we pick the best filtered bottle?

Filtration Technology – The actual technology and filtration ratings for each product were closely considered. Not all filters are capable of handling the same types of water sources. For instance, our top pick and our luxury pick are both rated for use in backcountry water sources and foreign countries with bad tap water – but many filtered bottles are NOT safe to use on these questionable sources. Pay close attention to the filter you are considering!

Brand Reputation – When it comes to the safety of your drinking water, you don’t want to cut corners. That’s why we chose products from very trusted brands in the industry, that stand behind their products and have the reputation to back up their claims.

Value – We steered clear of the cheapest options (because they’re not very effective), but we also tried to find affordable options for readers. We settled on great middle-ground products that offered an excellent balance between efficacy and price.

Ongoing Cost – All filtered water bottles will need new filters eventually. We factored in both the initial cost as well as the ongoing cost of replacement filters when making our decisions.
