Sawyer Products SP140 Personal Water Bottle Filter, 34-Ounce,Blue

Filtration on the Fly

In addition to drinking from the Water Bottle, you can also use the included filter inline with a hydration pack’s tubing or as an ultra-light filter for producing clean water for groups in the backcountry.

The cap is designed to fit standard 63mm wide mouth water bottles, so you can quickly switch the filter to any other compatible bottle.

Easy Hydration Everywhere

The Water Bottle's 0.1 absolute micron water filter produces clean water from freshwater lakes, rivers, and streams, as well as faucets in your home or hotel room while traveling (domestic and international).

It's also great for daily hydration while working out or taking to work.

Filter Again and Again

The Water Bottle's filter can be cleaned and reused almost indefinitely with no expensive cartridges to replace… ever.

When water flow begins to diminish, simply perform a backwash to restore water flow rate and enjoy fresh, clean water wherever you roam.

Sawyer's International Mission

Sawyer believes everyone deserves access to clean water — from hikers in the backcountry to indigenous people groups in the remotest corners of the world.

For over 10 years, Sawyer has been working with a variety of charities and churches who are on a mission to make a long-lasting impact in the lives of those around the world without access to clean drinking water.

Hollow Fiber Membrane

Sawyer’s water filters are comprised of tiny hollow fiber membranes that allow water to enter their core through tiny micro-pores.

Thicker fiber walls combined with a smaller inner diameter make Sawyer fibers 75% stronger* than typical hollow fiber membranes, giving you a fast flow and enabling the filter to be continually backwashed forcefully to restore up to 98% of the original flow rate.

0.1 Absolute Micron Filtering

Each Sawyer water filter features 0.1 micron absolute filtration, meaning there is no pore size larger than 0.1 micron in size.

This makes it nearly impossible for microplastics, harmful bacteria, protozoa, or cysts like E. coli, Giardia, Vibrio cholerae, and Salmonella typhi (which cause Cholera and Typhoid) to pass through.

Fiber Protection

Sawyer's hollow fiber membranes are fully encased and sealed to keep them protected. When fibers are not enclosed, physical damage of exposed fibers could allow harmful pathogens to pass through.

Tested 3 Times

Every Sawyer filter is performance tested three separate times during the manufacturing process for your protection.

Testing occurs after the fiber element construction and twice after casing assembly to ensure no harmful pathogens leak through the sealed case or internal O-rings.
