Water and air are essential for human survival, but the growing issue of drinking water pollution has always posed a threat to our health. In recent years, media coverage of water pollution has raised public awareness, leading to a surge in demand for water purification equipment. However, the quality of water purifiers on the market varies greatly, leaving many consumers confused and unsure how to choose the right one. When purchasing a water purifier, there are four key points you should never believe—let’s take a closer look.
**First, the lower the TDS value, the better the water quality.**
Many salespeople use TDS meters to measure the purity of water after it has been filtered. Tap water usually has a TDS value in the hundreds, and once it’s filtered, the number drops dramatically, which is often used as proof that the water is cleaner. But is a lower TDS value really an indicator of safer and healthier water?
In reality, TDS measures the amount of dissolved solids in water, including minerals like calcium, magnesium, sodium, and potassium, as well as some organic substances. While high TDS values may indicate more impurities, a very low TDS doesn’t necessarily mean the water is safe or healthy. Water quality is determined by a variety of factors, such as microbial content, heavy metal levels, and sensory properties like taste and color. A single TDS reading isn’t enough to determine if water is safe to drink.
Moreover, TDS can be affected by temperature and does not reflect the presence of harmful substances like bacteria, pesticides, or heavy metals. Even if the TDS is low, dangerous contaminants could still be present. Therefore, while a high TDS might signal poor water quality, a low TDS doesn’t guarantee clean, safe water.
**Second, using an electrolysis test proves water quality.**
Some companies use electrolysis experiments to demonstrate the quality of water. They claim that if the water turns dark during the process, it contains impurities. However, this method is misleading.
The so-called “electrolysis test†uses iron and aluminum rods to create a reaction. The resulting sediment is not an indicator of water quality but rather a chemical reaction caused by the electrodes. Tap water naturally contains minerals that conduct electricity, so the test results have little to do with the actual safety of the water. In fact, even purified water can produce similar results when salt is added. This means the electrolysis test is not a reliable way to assess water quality.
**Third, no wastewater means the purifier isn’t effective.**
Some manufacturers claim that if a water purifier doesn’t produce wastewater, it’s not filtering properly. However, this is not entirely true.
Different types of water purifiers work in different ways. Reverse osmosis systems typically produce wastewater, while ultrafiltration systems may not. The effectiveness of a water purifier should be verified through third-party testing, not just by whether it produces waste water. Professional labs use standardized methods to evaluate filtration performance, ensuring accurate and reliable results.
**Fourth, big brands are always trustworthy.**
Many people assume that well-known brands are always reliable. However, not all big names actually manufacture their own water purifiers. Some brands outsource production to Chinese factories and sell them under their name without significant R&D investment. Others may even misrepresent their technology, claiming to remove heavy metals or pesticides when they cannot.
A reputable brand should have a long history, strong research capabilities, and proper certifications. Consumers should check official approvals and licenses to ensure the product meets safety standards.
**In conclusion**, the rise in water purifier usage reflects increased health awareness. However, the market is full of misinformation and misleading claims. It’s important to be informed and cautious. Always choose a trusted brand, avoid exaggerated marketing, and rely on scientific evidence when making your decision.
