Portable disinfection card has limited effect and is difficult to use. Regarding epidemic prevention products, in addition to masks, there are often many new disinfection products on the market, which are claimed to have a 99.9% disinfection rate. For example, the \"disinfection card\" recently became popular on the Internet.
It is understood that there is a \"Japanese\" disinfection card, advertising that \"wear on the body, can achieve 99.9% of the bactericidal effect within 1 meter, the effect of a card can last 30 days, but also deodorizing, eliminating viruses, eliminating formaldehyde, eliminating mites.\" Compared with traditional disinfection products, disinfection cards are more convenient to carry, more extensive coverage, and more durable protection. In addition to the carry-on disinfection card, there is also a \"German\" disinfection card, which claims to be \"placed at home can be used in a space of 10-15 square meters.\"
Can they really get rid of viruses? What is the effect of use? \"The principle of disinfection card is actually the same as household disinfection box, the ingredients inside are a chlorination agent, through the effect of oxidation, to remove bacteria in the air around us,\" explained Liu Haonan, a testing engineer at the health appliances testing center of the China Household Electrical Appliances Research Institute. In order to verify the authenticity of the advertising effect, according to the requirements of the product manual, Liu Haonan did a test of the bactericidal effect in the air on the net red disinfection card.
The results showed that the bactericidal rate was 12.13% in the near place and 9.75% in the far place. Therefore, in actual use, hanging on the chest may be able to remove part of the surrounding bacteria, but the sterilization is certainly not clean enough, and the effect is very limited. By the same method, the bactericidal effect of household disinfection box was tested, and the bactericidal rate was 35.23%, which was also unqualified. In addition, the chlorine dioxide in the disinfection card is easy to cause eye and respiratory irritation after contact with the human body, and it is worn on the person, once it enters the water, the substance inside is directly in contact with the human skin, and there is a risk of burning.
It is worth mentioning that the reporter consulted a disinfection card store, whether the product holds a certificate, the store directly answered: no. There are many kinds of epidemic prevention devices on the network, and the publicity is very good, but the real sterilization effect is good and bad, and if you do not carefully choose, you will pay the \"IQ tax\".
It doesn't work. It's almost all about bragging rights. I wouldn't sell any sanitizer if it worked. So it's just to attract attention and interest and increase sales,
