What is Filtered Water?
Before directly heading towards our main topic, let’s first get a short overview of purified or filtered water. It is a type of water that goes through a filtration process to remove contaminants like chemicals, sediments, and tiny organisms that can make water unsafe.
When a filter removes all the harmful substances, the water will become completely clean and pure. Many people prefer the taste of filtered water over regular water from the tap since it is cleaner.
Can Filtered Water Expire?
Filtered water quality can go down over time depending on storage. Things like heat, light, and germs from unclean containers can cause filtered water to not taste as good. You can also relate all these things with “Expiration” as well.
It's best to drink filtered water within a couple of weeks if kept cold in the fridge. Storing it in a dark, clean bottle at cool temperatures helps keep it fresh the longest.
Tips for Properly Storing Filtered Water
In order to prevent filtered water from losing its quality, it is highly crucial for you to store it properly. Below, we have discussed some of the effective tips that you can consider following in order to store purified water.
1. Choose the Right Container
The type of container you use will impact how long your filtered water lasts. Opt for BPA-free plastic or glass bottles that are durable, leak-proof, and seamless.
These materials do not interact with water chemically and allow for airtight sealing to protect against outside contaminants. Look for containers with narrow mouths that are easy to clean and fill.
2. Store in a Cool, Dark Place
Heat and light can degrade your filtered water over time, so it's important to store it away from such elements. A cool, dark place like the back of your refrigerator or basement pantry helps keep water fresh for weeks.
The stable temperature keeps bacteria growth low while darkness protects the water from UV exposure that can cause chlorine levels to rise. Out of direct sunlight and heat, your filtered water will maintain its crisp, clean taste.
3. Use Airtight Containers
Using airtight containers for your filtered water storage is key to keeping it at its best. Exposing the water to air allows contaminants like bacteria, mold, and dust to potentially enter. Airtight bottles and dispensers seal out these pollutants.
They also prevent evaporation, so your filtered water supply lasts as long as possible. An airtight environment maintains your filtered water's purity and quality for however long it's kept before drinking.
4. Consume Within a Reasonable Timeframe
While filtered water lasts longer than tap, it still has a shelf life when stored properly. As a general rule, aim to finish bottled filtered water within one to two months in the refrigerator or within one week at room temperature.
The longer it sits, the more its taste and odor can slowly degrade. Going through your supply at a reasonable pace helps ensure you and your family always enjoy fresh, quality filtered water. Proper consumption will maximize the freshness.
These are the proven tips that you can follow in order to perfectly store purified water and prevent it from expiration.
How to Know Filtered Water is Expired Due to Poor Storage
There are multiple signs that will help you determine that the filtered water is expired and you should avoid consuming it.
1. Bad or Strange Odor:
If your filtered water is giving a strange odor, then this will be a clear indication or sign that it has expired. There can be a number of reasons behind bad odor, one is obviously poor storage.
Another reason for poor odor can be due to the breakdown of organic matter, and the presence of dissolved gasses.
2. Presence of Particles & Discoloration:
When the filtered water is expired, it will most likely exhibit visible signs of deterioration such as the presence of different particles or a change in color.
The particles can be sediment, minerals, or other impurities that became successful in tackling the filtration system. When it comes to color, filtered water may appear cloudy.
3. Microbiological Growth:
This is the final sign that will help you determine that the water is expired. The expiration makes the purified water more sustainable for algae or mold growth.
So, these are some of the common signs through which you can identify if filtered water is expired or not.
Frequently Asked Questions
Do different types of filters affect the expiration of filtered water?
Yes, the type of filtration system used definitely has an impact on the longevity of the water. For example, RO filters lose their effectiveness with the passage of time, so you will need to maintain them on a regular basis according to the manufacturer’s instructions.
Is it safe to consume purified water that is expired?
If it is confirmed that the filtered water is expired, then it is not recommended to drink it. This is because it can cause nausea, poor digestion, or other health issues.
Does the temperature at which filtered water is stored affect its overall shelf life?
Yes, storing purified water at a cool temperature can greatly assist in maintaining its overall quality over time. On the other hand, exposure to heat can decrease the shelf life.
Final Thoughts:
If filtered water is not used for a prolonged period of time, and is stored poorly, then there is a chance that it may lose its overall quality. For example, it may leave a bad odor or taste. Additionally, it can also be sustainable for algae or mold growth.
Due to this, it is recommended to either consume purified water within a short time frame or otherwise store it properly in a cool and clean place.
