Product Description

Next-Gen Survival Filtration: The iSpring IFS-B features a revolutionary Dual-Layer Electro-positive Membrane that captures viruses and lead—contaminants that standard hollow-fiber straws miss. Paired with a large CTO Carbon Core, it effectively reduces chlorine and odors for fresh-tasting water. Independently tested by SGS to reduce up to 99.9999% of bacteria, delivering reliable protection for hiking, camping, and emergency use. Sustainable & Cost-Effective Design: Stop replacing the whole unit. Unlike disposable filters, the IFS-B uses a replaceable core—just swap it out after 132 gallons to keep going. The filter is also washable and can be stored in the refrigerator to prevent mold and odors, ensuring it stays fresh for years of use.

Ultimate 3-in-1 versatility adapt to any water source instantly without lying on the ground:

• Direct Sip: Drink directly from streams or lakes using the straw.
• Bottle Adapter: Screws perfectly onto standard 28mm soda bottles to create a gravity or squeeze filtration system.
• Extended Reach: Use the included silicone hose to access hard-to-reach water.
