In today's world, water pollution has become a growing concern in our daily lives. As a result, water purifiers have emerged as a popular solution, capturing widespread attention. However, there are still many people who question their effectiveness. Some argue that while water purifiers remove harmful substances, they also strip away essential trace elements that are beneficial to the human body. This raises a critical question: is long-term use of purified water actually harmful to health? Let’s explore this issue further.
Tap water, which we commonly use in cities, comes from various sources such as groundwater, rivers, lakes, and even seawater desalination. These natural water sources are not safe for direct consumption. Especially in areas where rivers are polluted, the water must go through several purification processes at the water treatment plant—such as sedimentation, disinfection, and filtration—before it meets national drinking water standards.
But if the water from the treatment plant already meets safety requirements, why do we still need a water purifier? The answer lies in the distribution system. After being treated, the water travels through long pipelines, sometimes for miles, and these pipes can accumulate dirt, rust, and other contaminants over time. Additionally, chlorine is often used to kill bacteria, but it may leave behind residual amounts that can affect taste and quality. Moreover, certain impurities like scale, heavy metals, and volatile organic compounds might not be fully removed during the initial treatment process.
This means that by the time the water reaches your home, it may contain more contaminants than you expect. That’s one of the main reasons why so many people advocate for installing a water purifier. However, the debate around water purifiers continues, with the most common concern being whether they remove beneficial minerals from the water.
It’s important to understand that the filtration technology in modern water purifiers is quite advanced. Most models use multiple stages of filters—like PP cotton, activated carbon, and reverse osmosis membranes—to remove sediments, rust, bacteria, viruses, and even residual chlorine. While some of these systems do reduce mineral content, not all types of purifiers are the same.
For example, there are different types of water purifiers available. Some are designed for drinking water and retain some minerals, while others, like soft water machines, are meant for household use rather than direct consumption. Pure water machines, which often include a reverse osmosis membrane, remove nearly all minerals, making them unsuitable for regular drinking.
In reality, the amount of minerals obtained from drinking water is minimal compared to what we get from food. Our primary source of essential nutrients comes from the diet, not from water. Therefore, the main purpose of a water purifier is not to supply minerals, but to eliminate potential harmful substances that may have entered the water after treatment.
In conclusion, while concerns about mineral loss are valid, they should not overshadow the importance of removing contaminants that could harm our health. Choosing the right type of water purifier can help ensure clean, safe drinking water without sacrificing essential nutrients. It’s all about finding the right balance between purification and maintaining the benefits of natural minerals.
