The development of the water purification industry has made more and more water purifier brands sprung up, the so-called "dragon born nine sons", some of these brands rely on excellent product strength and after-sales service, won the trust of the majority of users, and some of them played "edge ball" to earn black money, once so that many users had a psychological shadow after being pitted, and then began to boycott all water purifiers.
Fundamentally speaking, the quality of the water produced by the water purifier is the key to judging whether the product is qualified. For a long time before, the TDS value was the hard core basis for testing water quality in the minds of many people, and even used it to determine the quality of the water purifier. With the continuous improvement of the understanding of water quality judgment, this basis still has a certain degree of scientificity on the one hand, and on the other hand, it also highlights its one-sidedness. Today we will talk about whether the TDS value can really test the quality of the water purifier.
TDS, which is the abbreviation of "Total Dissolved Solids", is called "Total Dissolved Solids" in Chinese. In addition to water molecules, there are various water-soluble solids in water, and the TDS value of water indicates the total amount of dissolved solids in the water. In general, the higher the TDS value, the more dissolved substances in the water, and vice versa. The TDS value is an intuitive measurement criterion and the process is fairly simple, with only a TDS pen required to produce results. In the case of non-intentional artificiality, we can basically assume that water with a low TDS value will be safer to drink than water with a high TDS value. So can this point of view be applied to water purifiers?
In general, TDS pens are only used to test the value of direct drinking water. Based on the premise of producing direct drinking water, the water purifier filter element group must be equipped with a RO reverse osmosis membrane with extremely high filtration accuracy, and all kinds of impurities in the water are eliminated through layer-by-layer filtration until it is close to the level of pure water (that is, there are only water molecules in the water).
If the TDS value is still high after filtration by the water purifier, after excluding the following two situations, you should consider whether the body failure or the quality of the water purifier you choose is qualified.
1. The water purifier is newly installed, or the filter element has just been replaced. The newly installed water purifier has a new filter element group, just change the filter element in the same way, before use, there is a layer of protective liquid on the surface of the filter element, the first time it is filtered, it will be mixed in the water and flow out, at this time, use the TDS pen to detect directly, there will be a phenomenon that the TDS value is too high, but it does not affect the health of the water quality. Of course, if you can't get over the hurdle in your heart, the solution is not difficult, just rinse the water purifier filter element thoroughly, and the specific method is to open the faucet and release water for a period of time (usually five to ten minutes), and then start normal filtration.
2. The water in the bucket of the water purifier is stored for too long. We often recommend that users need to rinse (i.e., drain the water operation) after not using the water purifier for a long time, especially if there is a bucket water purifier, the water in the water storage bucket is stored for a long time and has a high probability of deterioration, and the water produced will be higher under the detection of the TDS pen. Therefore, it is important to empty the remaining water in the bucket when reusing.
Of course, there are also blind spots in the detection of TDS value, such as the inability to detect bacteria and viruses in the water, which are important pathogens, and the reason why the TDS value cannot become a criterion for judging the quality of water quality. Even if there is some water with a high TDS value, it can be drunk directly, for example, put a certain amount of salt or sugar into a cup of water filtered by a water purifier, and stir it well, the TDS value can even be higher than most tap water, but do you feel that this water is not safe?
In summary, to judge the quality of water quality, the TDS value is a reference data, but it is only for reference, the lower the value, the higher the degree of filtration of soluble solids. If there is a quality problem with the water purifier filter itself, or it is shoddy, it may not be able to achieve the expected filtration accuracy, and it may not be able to block bacteria, viruses and other small substances, resulting in hidden dangers in the water still existing, and these TDS pens can no longer do anything.
For the water purifier industry, many consumers attach great importance to water quality issues, so the product quality requirements for water purifiers are getting higher and higher. In recent years, there have been some shoddy and low-quality products in the water purifier market, which has reduced consumers' trust in water purifiers. These incidents have sparked extensive online discussions and attention, and many have also reported and commented on these incidents.
In the repercussions on the Internet, many consumers began to doubt the judgment standard of the TDS value of the water purifier, believing that the TDS value could not fully reflect the water quality of the water purifier. They believe that the TDS value only measures the total dissolved solids content, but cannot tell whether there are microbial contaminants such as bacteria and viruses in the water. Therefore, more and more consumers have begun to pay attention to the filtration accuracy and filter quality of water purifiers. They believe that only by using high-quality and reliable water purifier products can all kinds of pollutants in the water be filtered out and the safety and health of drinking water can be ensured.
To some extent, this incident is similar to the previous false publicity incident of a water purifier brand. At the time, the brand claimed that its water purifiers could filter out all harmful substances in the water, making consumers mistakenly believe that they could enjoy safe and healthy drinking water as long as they bought the brand's water purifiers. However, in reality, the brand's water purifiers do not achieve the advertised effect and cannot completely remove microbial contaminants from the water. This incident has attracted widespread attention and caused some damage to the brand image and trust of the brand.
The impact of the development of water purifiers on society is very important. Water is the source of life, and the quality of drinking water is directly related to people's health and quality of life. With people's pursuit of health and the intensification of environmental pollution, water purifiers have become a must-have household appliance for more and more families. However, the development of the water purifier industry also faces challenges in terms of brand trust, product quality, and regulation. Damage to brand trust can have a negative impact on the entire industry, while poor product quality may lead to consumer confidence in the water purifier industry. The occurrence of this incident will further strengthen the call for the supervision of the water purifier industry and prompt enterprises in the industry to increase investment in product quality and after-sales service.
In terms of the latest developments, the relevant regulatory authorities investigated the incident and punished the water purifier brand involved. The brand was asked to improve its products and make a public apology, while regulators have tightened their grip on the water purifier market, increasing the rigor of product audits and taking tougher measures to combat false claims and shoddy practices.
Although the TDS value can refer to the water quality of the water purifier to a certain extent, it cannot be used as the only basis for judgment. The quality of the water purifier's products, filtration accuracy and filter element quality are equally important. When buying a water purifier, in addition to paying attention to the TDS value, consumers also need to understand the filtration principle, technical parameters and certification of the product, and choose the right water purifier product. At the same time, water purifier companies should also strengthen product quality control, improve the quality of after-sales service, and provide consumers with safer and more reliable drinking water solutions.
