1 Basic Difference Between Distilled and Purified Water

Distilled water and purified water are both types of water that have undergone different processes to remove impurities, contaminants, and minerals. However, there are some key differences between the two:

Distilled water is produced through the process of distillation, which involves boiling water to create steam and then condensing that steam back into liquid water. During this process, the impurities, including minerals, bacteria, and other contaminants, are left behind in the original container. The resulting water is essentially free from most dissolved solids and minerals, making it extremely pure.

Purified water is a broader category that encompasses various methods of water purification. There are different techniques used to purify water, such as reverse osmosis, deionization, carbon filtration, and UV sterilization, among others. These methods are designed to remove or reduce different types of contaminants, but they may not eliminate all impurities to the same extent as distillation.

Differences in Purity:

Distilled water is considered one of the purest forms of water because the distillation process removes nearly all impurities, including minerals, chemicals, and microorganisms. On the other hand, purified water may still contain trace amounts of some impurities, depending on the specific purification method used.

Taste and Quality Difference Between Distilled and Purified Water:

Due to the absence of minerals and other dissolved substances, some people find that distilled water has a flat or “empty” taste. Purified water, depending on the specific purification method, may retain some minerals and can have a more natural taste compared to distilled water.

Intended Use:

The choice between distilled and purified water often depends on the intended use. Distilled water is commonly used in scientific laboratories, medical equipment, and some industrial processes that require extremely pure water. It is also used in certain household appliances like steam irons and humidifiers to prevent mineral buildup. On the other hand, purified water is commonly used for drinking purposes and can be found in bottled water, as well as in some home filtration systems.

Coway water purifier:

Coway is a well-known company that manufactures and sells various home appliances, including water purifiers. Coway water purifiers are designed to provide clean and safe drinking water by removing impurities, contaminants, and odors from the water. They use advanced filtration technologies to ensure the water meets high-quality standards.

Some key features commonly found in Coway water purifiers include:

  1. Multiple Filtration Stages: Coway water purifiers typically employ multiple filtration stages, including pre-filters, activated carbon filters, and sometimes additional filters like UF (Ultrafiltration) or RO (Reverse Osmosis) membranes. Each stage targets specific contaminants, ensuring comprehensive water purification.
  2. Advanced Filtration Technology: Coway water purifiers often use advanced filtration technologies like RO, which can effectively remove even tiny particles, heavy metals, and dissolved solids from the water.
  3. Smart Features: Many Coway water purifiers come with smart features such as filter replacement indicators, water level indicators, and even Wi-Fi connectivity to provide real-time data and notifications.
  4. Compact and Stylish Design: Coway water purifiers are known for their modern, sleek design, making them aesthetically pleasing and suitable for various home settings.
  5. Energy Efficiency: Coway focuses on energy-efficient products, and their water purifiers are designed to consume minimal electricity while delivering optimal performance.
  6. User-Friendly Interface: Coway water purifiers typically have user-friendly interfaces with intuitive controls, making them easy to operate and maintain.

It’s important to note that specific models and features may vary, so it’s a good idea to check the product specifications and features of the particular Coway water purifier you are interested in.

As with any water purifier, it’s essential to regularly maintain and replace filters as per the manufacturer’s recommendations to ensure optimal performance and the continued delivery of clean and safe drinking water. Additionally, consider the water quality in your area and choose a model that addresses the specific contaminants that might be present in your water source.


Does boiling tap water purify it?

Boiling tap water is an effective method to purify it and make it safe for drinking and other purposes. Boiling tap water kills or inactivates most microorganisms, including bacteria, viruses, and parasites, which can cause waterborne illnesses. Boiling water is one of the oldest and simplest methods of water purification and is still commonly used in situations where access to clean water is limited or during emergencies.

The process of boiling water is straightforward:

  1. Bring the tap water to a rolling boil: This means that the water is vigorously bubbling and steaming. It’s important to maintain a rolling boil for at least one minute (or three minutes at higher altitudes) to ensure effective disinfection.
  2. Allow the water to cool: After boiling, allow the water to cool down before using or storing it. Boiled water is safe to drink, cook with, and use for other purposes like brushing teeth once it has cooled.

While boiling is an effective method to kill most microorganisms, it does not remove other types of impurities, such as dissolved minerals, heavy metals, chemicals, or any particles that may be present in the water. If tap water contains impurities other than microorganisms, additional purification methods might be necessary.

For comprehensive water purification that addresses a broader range of contaminants, consider using other methods such as water filters (like activated carbon or reverse osmosis filters), water purifiers, or a combination of filtration and disinfection methods.

Remember that the quality of tap water can vary based on the source and location. If you have concerns about your tap water’s safety or taste, consider contacting your local water utility or using a water testing kit to get a better understanding of its composition.

In summary, distilled water is a specific type of purified water produced through the process of distillation, and it is considered one of the purest forms of water. Purified water, on the other hand, is a broader category that includes various methods of water purification, and while it is also purified, it may not reach the same level of purity as distilled water.
