With the Eddy+ Filtered by LifeStraw, water passes through two separate stages of filtration – the hollow fiber filter removes bacteria, parasites, and microplastics and the ion exchange filter reduces lead, bad taste, chlorine, and other unwanted chemicals. Leak-proof when closed and spill-proof when open, the universal Eddy+ straw cap and bite-valve interface delivers a high flow for steady hydration when you need it most. The main vessel is made with Tritan Renew, a highly durable and lightweight plastic made with 50% recycled material. A more sustainable solution, Tritan Renew is made using a recycling process that is more efficient than standard mechanical recycling, producing a superior material with less demand on finite resources. It is odor and stain resistant and free of BPA, BPS, and BPF.
