Sawyer Select S1 Foam Water Filter
The Sawyer Select S1 Foam water filter allows you to have access to safe and clean drinking water anywhere. This system includes a robust silicone bottle equipped with a patented foam membrane and a 0.1 micron hollow fiber filter at the top.
This filter reduces the presence of chemical compounds to just 0.5 parts per billion—which is 40 times below the EPA's suggested upper limit—and lowers the number of pesticides to 0.01 parts per billion, which is 400 times below the EPA maximum. The filter not only eliminates bacteria, protozoa, chemicals, and pesticides but also noticeably improves the taste and odor of the water.
You can use the Sawyer Select S1 Foam water filter approximately 1,600 times before a filter replacement is needed.
How to use the Sawyer Select S1 Foam water filter?
- Unscrew the filter, fill the bottle to the 'Max Fill' line, and screw the filter back onto the bottle.
- Squeeze the bottle for 10 seconds with a rotating motion.
- Drink directly from the filter or pour the water into another reservoir.

“Perfect for emergencies and camping trips.”The solar powered radio keeps charging even when we’re off-grid. The flashlight is surprisingly bright, and the radio reception is crystal clear.
The Emergency Box Pro exceeded my expectations. It feels durable, thoughtfully packed, and perfect for home preparedness. I bought one for our family after a storm knocked out power last winter, and now I feel way more prepared for emergencies.
I travel a lot for work, so the Emergency Pack Pro has become part of my everyday carry. Lightweight, easy to store, and surprisingly complete for its size. It gives me peace of mind without feeling bulky or overkill.
