Is Boiled Water the Same as Filtered Water?

by Dr. Jonathan Doyle - Updated December 15, 2024
When it comes to ensuring safe and clean drinking water, many Australians rely on either boiling or filtering their water. But have you ever wondered if boiled water is the same as filtered water? In this blog post, we will explore the key differences between boiled and filtered water, helping you understand which option is better for your health and household needs.
Whether you are concerned about the taste, health implications, or the best method for purifying your water, we’ve got you covered. Let’s dive into the details to find out which method is the most effective and why it matters for you and your family.

What Happens When You Boil Water?

Boiling water is a simple yet effective method of killing bacteria, viruses, and other harmful microorganisms. When you boil water, it reaches a temperature of 100°C, which is sufficient to destroy most pathogens that could be present. This is why many people choose to boil water, especially when they’re unsure about its safety or if they’re in an area where the water supply might be compromised.

However, while boiling is an effective way to eliminate germs, it doesn’t address other potential contaminants like chlorine, heavy metals, or dissolved chemicals that may be present in the water.

Does Boiling Water Remove Impurities?

While boiling does kill bacteria, viruses, and parasites, it does not remove chemical contaminants, heavy metals, or sediment. For example, chemicals such as lead, arsenic, and chlorine will remain in the water after boiling. So, although boiling makes water safer to drink by killing most pathogens, it does little to improve its overall quality.

How Does Water Filtration Work?

Water filtration involves the use of a device or system to physically remove contaminants from the water. There are several types of water filters, including activated carbon filters, reverse osmosis water filter, and UV (ultraviolet) filters. These filters target a variety of contaminants, such as chlorine, sediments, pesticides, heavy metals, and even some microorganisms.

Types of Water Filters Commonly Used in Australia

In Australia, there are several popular methods of water filtration. Some of the most commonly used filters include:
  • Activated Carbon Filters: These filters use carbon to absorb chlorine, sediments, and other chemicals, improving both the taste and safety of water.
  • Reverse Osmosis Filters: Reverse osmosis is a highly effective filtration method that removes a wide range of impurities, including salts, heavy metals, and microorganisms. This method is often used in areas with poor water quality or high levels of contaminants.
  • UV Filters: UV filtration uses ultraviolet light to kill bacteria and viruses. While UV filters don’t remove chemicals or physical particles, they are effective in ensuring microbial safety.
  • Distillation: This method involves boiling water and then condensing the steam back into liquid form, which helps to remove most impurities, including heavy metals, minerals, and microorganisms.
  • Does Filtration Remove Contaminants?

    Yes, filtering water can remove a wide range of contaminants, depending on the type of filter you are using. For instance, reverse osmosis filters can remove up to 99% of contaminants, including heavy metals and dissolved salts. Activated carbon filters can reduce chlorine levels and improve the taste and odour of the water, but they don’t remove heavy metals or minerals. UV filters, as mentioned, only kill microorganisms.

    Comparing Boiled Water and Filtered Water: Which Is Better?

    Now that we have a clear understanding of both boiled and filtered water, let’s break down the comparison to help you decide which one is right for you.

    Effectiveness in Removing Contaminants

  • Boiled Water: While boiling is excellent for killing harmful bacteria and viruses, it doesn’t eliminate other harmful substances like chlorine, heavy metals, or chemicals. Boiled water may still taste unpleasant or contain pollutants that could have long-term health effects.
  • Filtered Water: Filtration, on the other hand, is more versatile. Depending on the filter, it can remove a wide range of contaminants, including chemicals, heavy metals, and sediments. Reverse osmosis filters, in particular, are highly effective at removing dissolved solids, including salts and minerals, which boiling cannot do.
  • Taste and Odour

  • Boiled Water: Boiling can affect the taste of the water, as it can leave behind dissolved solids like salts and minerals. Additionally, if your water has a high level of chlorine, boiling it can make the taste even more noticeable.
  • Filtered Water: Water that has been filtered through activated carbon or other filtration methods tends to taste fresher and cleaner. Filters help remove chlorine, sediments, and other contaminants that can cause bad odors and flavors, making filtered water the preferred option for better-tasting water.

    Cost and Convenience

  • Boiled Water: Boiling water requires a stove or kettle, which means it can be more time-consuming and less convenient, especially when you need large quantities of water. Additionally, if you’re boiling water frequently, the cost of energy or gas can add up over time.
  • Filtered Water: While high-quality filters can be an investment, they are typically more convenient in the long run. Once installed, filters provide an ongoing supply of purified water with minimal effort. Plus, there are no ongoing energy costs involved with using a water filter, unlike boiling.
  • Which Option Should You Choose?

    Ultimately, the choice between boiled and filtered water depends on your priorities and the water quality in your area.
  • If your primary concern is microbial safety (bacteria, viruses, parasites), boiling is a quick and effective option.
  • If you want to ensure your water is free of chemicals, heavy metals, and improves taste, then a filtration system is the better choice.
  • If you’re looking for a convenient and long-term solution to water purification, filtering is a more sustainable and hassle-free option.

    For those living in areas with poor water quality, such as parts of rural Australia, or if you are concerned about harmful chemicals, investing in a good filtration system might be the best solution. On the other hand, if you’re on the go and need a quick fix to ensure safe drinking water, boiling may be your best bet.
    For optimal results, some Australians choose to combine both methods. For instance, they might filter the water first to remove chemicals and heavy metals and then boil it to ensure it is free from bacteria and viruses. This provides the best of both worlds: cleaner, safer, and better-tasting water.

    Conclusion

    In the end, while both boiled and filtered water have their benefits, they are not the same. Boiling water is effective for killing microorganisms but does not address chemical contaminants, whereas filtration can remove a wide range of impurities, including chemicals and heavy metals. Depending on your needs, you may want to choose one method over the other, or even combine both for the highest level of water purity.
    Whatever you decide, it’s essential to be informed about your options so you can make the best decision for your health and home. After all, clean water is crucial to maintaining a healthy lifestyle, and knowing how to purify it effectively ensures that your family stays hydrated and safe.
