The most important reason to say ‘yes’ to stainless steel water bottles is their hygienic material and long-lasting durability. Since they do not break if dropped, they can be used for a much longer period than regular bottles. Stainless steel is the most hygienic and safe material, as it does not contain bisphenol and carcinogenic substances, unlike some low-quality plastic or aluminum containers. Additionally, stainless steel does not harbor bacteria, even if scratched. Let’s not forget that it is the first choice of material for making hospital equipment and kitchenware.
