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. 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 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.
How to Use
Step 1Unscrew the filter, fill the bottle to the Max Fill line, then screw the filter back onto the bottle.
Step 2Squeeze the bottle in an alternating motion for 10 seconds.
Drink directly from the filter or dispense water into another container.
The Select systems reduce chemicals down to 0.5 parts per billion (up to 40 times lower than the EPA’s maximum recommended level) and reduce pesticides down to 0.01 parts per billion (400 times lower than the EPA’s maximum).
The Select S3 models go even further, purifying contaminated water from suspect sources:
Select S3 filters out 99.99% of viruses and reduces heavy metals such as lead, copper, arsenic, and mercury down to 0.5 parts per billion (up to 260 times lower than the EPA’s maximum).
Completely drying out the the Select Bottle is not necessary. The adsorption filtration technology within the foam is designed to both filter water as well as prevent growth. If you do dry it out and mold grows on the unprotected walls of the bottle, fill the bottle with water and continuously squeeze and release for approximately 3 minutes or until the mold is gone.
