Why stainless steel is the best choice for a healthy drinking bottle
If you consciously choose a healthy and sustainable lifestyle, you also want to know what you're drinking from on a daily basis. Disposable plastic has long since been ignored. But even with reusable bottles, there are differences in safety, durability and ease of use. Many people hesitate between aluminum and stainless steel (SS). Time to clarify: Stainless steel is by far the best choice. And aluminum? Those are best avoided.
Aluminum bottles: light, but not without risk
At first glance, aluminum seems like a good alternative: it is light, stylish and easy to carry. Yet it has significant drawbacks. Aluminum reacts with acids and therefore always needs an inner plastic layer. This layer may contain microplastics or chemicals such as BPA - substances you would rather not have in your body.
Even with a BPA-free coating, aluminum is less safe. That inner layer can be damaged, especially with hot drinks or through daily use. As a result, the aluminum still comes into contact with your water. In addition, aluminum is not heat-resistant, making it difficult to clean the bottle. So no dishwasher, and therefore more risk of bacterial growth.
Stainless steel drinking bottles: safe, strong and tasteless
Stainless steel drinking bottles are the safest choice for daily use. Stainless steel is a non-toxic, sturdy material that requires no coating. Even when damaged, it does not give off harmful substances. Even with hot drinks such as tea or coffee, stainless steel remains completely safe and neutral in taste. A stainless steel bottle - especially of 18/8 quality (18% chromium and 8% nickel) - can withstand high temperatures and is therefore thoroughly cleanable. Dishwasher? No problem. This keeps your bottle fresh, clean and free of bacteria.
