Stainless Steel vs Aluminum


Why Choose Stainless Steel Instead of Aluminum?

AffirmWater Bottles are made from 18/8 (#304) food-grade stainless steel.

Stainless steel is recognized as one of the safest choices for water bottles because there is no leaching.

Aluminum is a metal from metal refineries and mining operations.   Potential health impacts associated with Aluminum include cardiovascular or blood toxicity, neurotoxicity, reproductive toxicity, and respiratory toxicity.

Because of these problems, aluminum bottles are sometimes lined with a plastic or epoxy to make sure the liquid doesn’t come into contact with the aluminum.

Concerns have arisen about a chemical call “Bisphenol A” or BPA which is a component of the lining.  BPA is linked to disrupting hormone functioning, altering genes and interfering with normal physical and behavioral development.

Over time the lining can crack or wear off with continued cleaning, causing exposure to chemicals such as BPA and aluminum which is why aluminum bottles are generally NOT dishwasher safe.

The environmental impact from aluminum ranges from the extraction to processing.  The major environmental impact of refining and smelting is green house gas emissions.

Stainless Steel provides a safe, durable, lightweight, hygienic, environmentally friendly, cost-effective, dishwasher safe alternative to aluminum and plastic water bottles.
