Enjoy safe, clean water anywhere in the world with the Sawyer® Select Water Purifier. The S3 removes virtually all contaminants found in fresh water, while also improving taste and odor. The system combines 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 that further reduces contaminant levels well below EPA standards for safe, clean drinking water. The 0.1-micron filter ensures that all particulate and pathogens above 0.1 microns are filtered out of your water, including viruses, bacteria, protozoa, cysts, dirt and sediment.

Each bottle features a dense foam core that blends activated carbon and other proprietary ingredients to remove small contaminants that the 0.1-micron filter can't capture alone—including chemicals and pesticides. The Select S3 Purifier also reduces heavy metals such as copper, arsenic, and mercury down to 0.5 parts per billion (260 times lower than the EPA’s maximum). That makes it ideal for use at home, abroad, and even near mining operations.

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.
