Water itself does not go bad in the fridge as long as it is properly stored in a clean, sealed container. Unlike food, water does not spoil or decompose. However, water can absorb odors and flavors from its surroundings, which may affect its taste after a while.
If you store water in a refrigerator in a clean and closed container, it can remain safe to drink for an extended period. The timeline for how long water lasts in the fridge depends on various factors such as the cleanliness of the container, the quality of the water, and the conditions inside the fridge. Here are some general guidelines:
Tap Water: If you store tap water in a clean, tightly sealed container, it can remain safe to drink for a few days to a week in the refrigerator. However, after several days, it might start to develop a stale taste due to the absorption of odors and gases from the fridge.
Filtered Water: If you use a water filter to purify your tap water, the filtered water can generally stay fresh for a bit longer, typically up to two weeks in the fridge.
Distilled Water: Distilled water, which has been purified through the process of distillation, can last for several months in the fridge if stored in a clean, airtight container.
It's essential to use proper hygiene when handling water and its container. Make sure to use clean hands and clean containers to avoid contamination. If the water develops an unusual smell, taste, or appearance, it's best to discard it.
If you want to ensure that the water stays fresh and doesn't absorb any fridge odors, consider storing it in a pitcher or bottle specifically designed to keep odors out, or use a water filter pitcher with a built-in filter to enhance the water's quality and taste.
