Advanced water filtration made easy – The Select S1 filters water of chemicals, pesticides, bacteria, and protozoa in just 10 seconds as well as improving bad taste and odors. 

Sawyer International says

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 our 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 chemicals, pesticides, and bacteria 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 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.

Our Verdict

The Sawyer Select S1 Foam Water Filter combines Sawyer’s signature 0.1 micron absolute Hollow Fibre Membrane filter with a propriety Foam Membrane to remove virtually all contaminants found in fresh water.

Below is a table to help you decide on which of the three Select Systems is right for you.
