The question you might find yourself asking is does distilled water ever go bad?

In general, normal water rarely goes bad on its own, however, packaging and the outside environment can have a lasting impact on how long your water lasts and the quality thereof.

Distilled water goes through a purification process of distillation, leaving water that is free of impurities and unwanted minerals. Due to this physical characteristic, distilled water is susceptible to absorbing carbon dioxide from the air increasing its acidity level.

Shelf Life of Distilled Water

As the air hits the distilled water, naturally the conductivity of the water will increase over time and some contamination will occur. However, due to the purity of distilled water, the contamination that will occur will be minimal compared to normal mineral water.

In saying this, the container you store your distilled water in will inevitably prolong or deteriorate the shelf life of your water. - For example, plastic containers can seep unwanted chemicals into distilled water and reduce its quality at a rapid rate.
