How Long Can Water Sit in a Water Cooler

Does Water Expire?

Have you ever bought a pack of bottled water? If yes, you must have noticed an expiry date printed on the packaging.

In fact, most bottled water manufactured in the US comes with an expiry date.

So, does this mean that water can expire? And is it safe to drink the water past the indicated expiration date?

Well, although bottled water comes with an expiration date, the water itself doesn’t expire. However, this doesn’t make drinking water from bottles that are way beyond the expiry date any better.

Over time, plastic can leach into the water, contaminating it with chemicals like bisphenol A and antimony.

Ingest these chemicals regularly, and you might have your immunity, gut health and respiratory function.

Proper Water Storage Tips

Storing your bottled water properly helps prevent bacterial growth and reduce health complications such as stomach pain, nausea, vomiting and diarrhea.

Warm temperatures fasten bacterial growth while increasing the release of toxic plastic chemicals into the water.

Store your bottled water in a cool place and away from direct sunlight if you intend to reduce the risk of negative side effects. You’ll also be promoting proper food safety.

Since plastic bottles are slightly permeable, always store your bottled water away from your cleaning supplies and chemicals.

And should you notice that your bottled water has developed a funny taste or odor, boil it before drinking. You can also discard it.

How long can water sit before it goes bad?

If you store your tap water properly, it should be healthy for consumption for up to 6 months. However, if the water is carbonated, it gets flat as the gas escapes slowly, resulting in changes in flavor.

Regular water also develops a stale taste over time. This is caused by the mixing of carbon dioxide in the air with water. The process makes the water more acidic.

The good news is that even with the off taste, the water is still considered safe to drink up to the 6th month.

Therefore, use clean and sanitized food-grade containers to prepare your tap water for storage. Store the containers in a cool, dry place away from direct sunlight for up to 6 months.

Water in an unopened plastic bottle can sit there for up to 2 years if non-carbonated. Sparkling water has a shelf life of one year.

How long can filtered water sit out?

If stored in a plastic bottle and put in the fridge, filtered water can last for a few weeks. The bottle in question needs to be clean and airtight to prevent external contaminants from entering.

At room temperature, filtered water can only stay in pristine condition for only a few hours.

Leaving your filtered water out at room temperature might not be wise. This temperature is usually warm and, as such, exposes the water to heat and other elements in the air.

These elements can pollute your filtered water, change its taste and most likely, add bacteria or microorganisms to it.

How long can you leave water in a bottle?

If using the water daily, you can leave it in a stainless steel or plastic bottle for a day. You should clean the water bottle daily to prevent mould and bacteria growth, especially if bringing it outdoors.
