The CamelBak 2652001000 is a LifeStraw Bottle Filter Set specifically designed as a replacement for the Eddy+ 20oz Bottle. This compact, size small set perfectly fits the said bottle, which is constructed using Tritan Renew plastic.It provides broad-spectrum water purification, integrating a two-phase filtration process. Initially, a hollow fiber filter eliminates bacteria, parasites, and microplastics present in the water. Subsequently, an ion exchange filter plays its part, reducing lead content, eliminating chlorine, and improving the flavor by removing other undesirable chemicals.
