Sawyer SP160 Gravity Water Filtration System Hands-Free Urban Survival Water Filtration System The Sawyer SP160 is your go-to solution when you need to filter large amounts of water quickly and with zero effort. Designed as a lightweight, packable system, this urban survival water filtration system is ideal for families, apartment dwellers, or anyone preparing for water supply interruptions in the city. With its 1-gallon reservoir and gravity-fed operation, the SP160 gives you safe drinking water without the need for squeezing, pumping, or electricity. This kit includes: 1-gallon BPA-free water reservoir bag Sawyer MINI 0.1 micron absolute hollow fiber filter Hose and connectors for gravity setup Cleaning plunger for backflushing maintenance How It Works: Gravity Hollow Fiber Membrane Filtration At the heart of the SP160 is Sawyer’s trusted 0.1 micron hollow fiber membrane filter—the same advanced technology used in kidney dialysis. Here’s what happens: ✅ Fill the bag: Pour untreated water into the 1-gallon reservoir. ✅ Let gravity work: Hang the bag or place it above the filter. Gravity pulls water down through the filter’s dense network of U-shaped microtubes. ✅ Clean water flows out: The filter physically removes contaminants as water passes through: 99.99999% of bacteria (E. coli, Salmonella, Cholera) 99.9999% of protozoa (Giardia, Cryptosporidium) 100% of microplastics ✅ Backflush to clean: Use the included plunger to push clean water backward through the filter, clearing out debris and restoring flow. With proper care, the system can purify hundreds of thousands of gallons over its lifetime. Why It’s Essential for Urban Survival Perfect for families or groups – Filters up to 1 gallon of water in 7–10 minutes ️ Urban emergency ready – Be prepared for water main breaks, boil advisories, or hurricane aftermath Hands-free operation – Set it up and focus on other tasks while it works Reusable & long-lasting – No need for replacement cartridges; just backflush and keep going Compact enough to store in a kitchen cabinet or bug-out bag, the Sawyer SP160 brings peace of mind in a world where clean water isn’t always guaranteed.
