Best filtered water bottles for 2021 to remove bacteria, sediment, and more to reduce waste in 2022

A clean drinking water bottle for clean water is an essential piece of adventuring gear, whether you're going for a short hike or completing an extensive wilderness backpacking trip. Gallons of purified bottled water can be heavy, expensive, and an environmental nightmare.

Frankly, it isn't even an option.

Even if a water source appears clean, it may be nonpotable contaminated water with viruses, harmful bacteria, protozoa, or other microorganisms invisible to the human eye. And despite the Safe Drinking Water Act, tap water can still contain contaminants such as lead, chlorine, arsenic, pesticides, and even particles from improper wastewater treatment. Why not try filtered water instead?

Six filtered water bottles were put to the test at a fresh groundwater source in Southern California.

Choosing a filtered water bottle may be the best option if you're retiring from plastic water bottles or disposable water containers and opting for bottled water.

  • You're unsure about your tap water
  • You travel to other states and countries where you don't know about water practices and it might contain harmful contaminants
  • You go hiking, backpacking or on other outdoor adventures
  • You prefer bottled water but want to reduce your plastic waste

To that end, I tested six filtered water bottles to find the best filtration water bottle you can trust to provide you with clean, safe water, indoors or outdoors.

My only complaint is that eventually, backflushing won’t be enough. These can clog up after some time and no amount of back flushing will fix its low flow. I went through 2 on the AT. However, it will attach to Smart Water Bottles and most bladders!

Built for backcountry reliability and portability, the Sawyer Squeeze filter is our pick for the best portable water purifier.

The Sawyer Squeeze was (by far) the most common Pacific Crest Trail water filter this year – for the fifth year in a row. It’s a $39, 3 oz / 85 g hollow fiber filter that rids your drinking water of protozoa and bacteria (and floaties). It can be used with Sawyer bags (included with the filter) or with compatible water bottles (Smartwater is the bottle of choice for many hikers).
