Product Description
The iSpring FIFS Replacement Filter Element is designed exclusively for the iSpring IFS-B Personal Water Filter Straw. Replacing your used filter core restores flow performance and filtration efficiency. Next-Gen Filtration Unlike standard hollow-fiber filters that rely purely on physical pore size, the FIFS features an advanced Electro-positive Membrane. It acts like a powerful magnet, instantly adsorbing ultrafine threats like viruses and lead. Paired with an inner Solid CTO Carbon Block, it effectively reduces chlorine, bad odors, and harsh tastes, delivering crisp, chemical-free hydration. Easy Installation: Simply twist the IFS-B nozzle counterclockwise, pull out the old core, and insert the new FIFS. The precision-fit design guarantees a 100% leak-free seal with zero water bypass. Note: This package contains the replacement filter element only. The iSpring IFS-B outer housing and accessories are sold separately.
