When you’re living your man vs. nature dreams in the backcountry, access to clean water is paramount to keep your adventure going. There are plenty of water filters to choose from but we believe they don’t get any better than Sawyer’s foam filters and purifiers.
All three models combine a proprietary foam membrane and a durable silicon bottle with Sawyer’s 0.1-micron hollow fiber filter, ensuring access to clean water outdoors, in the office, or in emergency situations. The most aggressive of the bunch is the S3 Foam Filter, which removes heavy metals, viruses, bacteria, protozoa, chemicals, and pesticides. Not to mention, the foam filter also improves taste and odor while being more compact and lighter than other water filters. The foam absorption technology used in the purifiers was developed with the help of Formulations LLC to give these models the rigorous purifying capabilities to provide you with clean water anywhere. All you have to do is fill the bottle to the max line, squeeze it in an alternating motion for 10 seconds, and like magic, you have drinkable water. Choose from the S1, S2, or S3 Foam Filters, depending on how intense you want your filtration.
