3rd in the Sawyer Select series. Sawyer Select S-3 Red Water Purifier Bottle. Good for 400 uses (62.5 gallons).

Enjoy safe, clean water anywhere in the world with Sawyer Select Water Filters and Purifiers which remove virtually all contaminants found in fresh water while also improving taste and odor.

Available in three models, these systems combine a proprietary foam membrane in an durable silicone bottle with the 0.1 micron hollow fiber filter at the top — ensuring access to clean water in the backcountry, while you travel, at the office, or for emergencies.

The Foam Adsorption Technology used in these systems was developed with a partnership with Foamulations LLC to now be able to safely remove contaminants like heavy metals, chemicals, pesticides, and viruses while also improving taste and odor. Adsorption filtration is the process in which molecules adhere to the surface of the adsorbent foam membrane. This highly advanced filtration and purification process, combined with our 0.1 micron absolute filter will ensure that any and all particulate or pathogens above 0.1 microns are filtered out of your water, including bacteria, protozoa, cysts, dirt and sediment.
