What is the LifeStraw Go Series membrane microfilter made from?

The LifeStraw membrane microfilter is made from high-performance, BPA-free polymers known for their toughness and stability at high temperatures. These properties make them essential for filtration by maintaining pore size under challenging conditions. The membrane microfilter is made from hollow fiber membranes. These membranes consist of small, straw-like tubes with microscopic pores (0.2 microns), which physically filter out contaminants such as bacteria, parasites, and microplastics as water passes through. The hollow fiber technology is highly effective in providing clean, safe drinking water.
