Do these “disinfection artifacts” really work?

  Air disinfection cards, blue light disinfection guns, air disinfection machines… On major e-commerce platforms, many merchants have launched a variety of “disinfection artifacts”, which has led to a sharp increase in sales of disinfection products.
  In the promotion of some “disinfection artifacts”, “360° coverage within 1 meter”, “nano-level atomization, ultra-long range, no dead angle disinfecting”, “ultraviolet sterilization, ozone disinfection, virus killing rate of 99.99%”… Similar descriptions can be seen everywhere. Do these disinfection products really have miraculous effects, or are they just a gimmick for publicity?
Can the air disinfection card achieve full coverage within 1 meter?

  ”Black technology provides efficient protection, reducing the probability of cross-infection for children in public places such as kindergartens and schools.” On an e-commerce platform, an air disinfection card with monthly sales of over 10,000 declared on the product details page “Wear it on the body, within 1 meter 360° coverage inside, and the endurance of sterilization and disinfection can reach two months.”
  Some consumers buy air disinfection cards out of the mentality of adding a layer of security to themselves or their families. As for the protective effect of the disinfection card, it is difficult to have an intuitive judgment. In the product reviews, many consumers said that “I don’t know if it is useful, just for psychological comfort”, and some consumers said bluntly, “Just pay the ‘IQ tax'”.
  A test on the sterilization effect of air disinfection cards conducted by the Healthy Appliances Testing Center of China Household Electrical Appliances Research Institute showed that each disinfection card contained 3 to 15 grams of chlorine dioxide gas generating agent. In most daily life environments, The effective concentration for sterilization and disinfection cannot be reached. In the test chamber of 3 cubic meters, the sterilization rate of the place far from the air disinfection card is only 9.75%, and the sterilization rate of the place close to it is only 12.13%. Experts clearly pointed out that “the chlorine dioxide patch can form a ‘protective barrier’ around the body to help block virus infection” as a rumor.
Can the blue light disinfection gun assist in sterilization?

  How can common disinfection products such as alcohol and 84 disinfectant exert greater efficacy? According to some merchants who sell disinfection spray guns, after putting these liquids into the water tank of the spray gun, and then spraying them through the high-pressure air pump and atomizing nozzle, the output of nano-scale atomization can be achieved and the aerosol transmission path can be blocked. Not only that, but merchants also claim that most spray guns have added a blue light function, which can assist in sterilization and disinfection.
  ”The front end of this blue light disinfection gun is equipped with an ultraviolet disinfection lamp.” It is understood that blue light and ultraviolet light are different concepts, but some disinfection guns deliberately confuse the two in the promotion, and use the disinfection principle of ultraviolet light to promote blue light disinfection gun.

  ”‘Blue light disinfection spray’ is an unreliable concept. It is difficult to expect to use the blue light on this product to kill the new crown virus. Direct spraying may also cause damage to human eyes and skin, which is relatively safe. Hidden dangers.” The household appliance industry practitioners said.
  In addition, if alcohol is sprayed with a disinfection gun, there may be an additional safety risk. Firefighters reminded that clothing such as down jackets and chemical fiber materials are prone to friction and generate static electricity. Spraying atomized alcohol on a large area is fully exposed to oxygen, and it is easy to be ignited and caught fire. Be cautious when purchasing and using such products.
Will air disinfection become a new blue ocean for home appliances?

  In the market of household disinfection appliances, disinfection appliances represented by air disinfection machines are becoming more and more popular. In the product introduction of the air sterilizer, the “space shield” and “protection without dead ends” are the highlights of the air sterilizer. Faced with the continuous growth of the market size of air sterilizers, some analysts believe that this will be a new blue ocean for the home appliance industry.
  However, as an emerging product, the quality of products on the market varies, and the effect of household air disinfectors remains to be tested by the market. Many air sterilizers that should be managed as disinfection products have not even been reviewed and filed by the Health Commission before they go on the market.
  In the face of many home appliance brands entering the disinfection appliance industry one after another, experts said that although these products can indeed attract consumers’ attention in the short term, if the product promotion is exaggerated under the premise that the national or industry standards are not yet clear, once the product fails to meet the advertised As a result, it will have a negative impact on the brand image, and the home appliance industry should operate in a standardized and orderly manner.
Consumers need to be more rational

  In many questions and answers on “disinfection artifacts” on the e-commerce platform, some consumers asked whether the product is an IQ tax. Consumers who have used it also have different experiences. Some people think it is useful, at least spending money to buy a sense of security, and some people think it is completely useless. In the face of all kinds of “disinfection artifacts”, how can we not be charged “IQ tax”?
  Experts believe that if household disinfection appliances claim to be able to kill the new coronavirus, consumers may have to put a question mark on the authenticity of the propaganda, because the virus itself is constantly mutating, and it is difficult to determine whether a certain disinfection method is always effective. As for the promotional phrases such as “99.99% sterilization rate”, further explanations are needed to explain which types of bacteria are removed. Deliberately expanding the concept may involve false propaganda.
  Experts pointed out that from the perspective of merchants, if a certain category of disinfection products wants to gain the trust of consumers, it must first ensure product quality, and second, it must abide by relevant national standards. In addition, the marketing level should also be carefully publicized. If the disinfection effect must be used as a selling point, then the content of the promotion must be based on the test certificate issued by a qualified authority, and cannot be exaggerated to deceive or mislead consumers. For consumers, they also need to be more rational when preventing epidemics at home.
