This Go stainless steel tumbler features a membrane microfilter that effectively filters out contaminants, including bacteria (such as E. coli and Salmonella), parasites, microplastics, sand, dirt, and cloudiness commonly found in tap water and ice, while its slim 500 ml (18 oz.) stainless steel design allows it to fit most car cup holders for convenient use during commuting or errands. It also improves taste thanks to an activated carbon filter that reduces chlorine, odours, and certain organic chemical matter, while maintaining long-lasting performance.
