Sawyer S1 Foam Filter Bottle
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.
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.
