Enjoy safe, clean water anywhere in the world with Sawyer® Select Water Filter. The S1 removes virtually all contaminants found in fresh water, while also improving taste and odor. The system includes a durable, portable silicone bottle, Sawyer's signature 0.1-micron ABSOLUTE Micro Squeeze Filter at the top, plus an additional proprietary foam core inside the bottle with foam adsorption technology. The proprietary foam safely removes contaminants like chemicals and pesticides using adsorption filtration. When combined with the ABSOLUTE Filter, this highly advanced filtration process ensures that all particulate or pathogens above 0.1 microns are filtered out of your water, including bacteria, protozoa, cysts, dirt and sediment. The Select system reduces chemicals down to 0.5 parts per billion (up to 40 times lower than the EPA’s maximum recommended level) and reduces pesticides down to 0.01 parts per billion (400 times lower than the EPA’s maximum).
And it's simple to use. Just unscrew the filter from the top of the Select System, fill the bottle to the "Max Fill" line, then screw the filter back onto the bottle. Squeeze the bottle in an alternating motion for 10 seconds, then drink directly from the filter, or dispense the water into another container.
