The air conditioner did not kill H5N1

Many types of air conditioners, refrigerators, washing machines . are advertised to help kill viruses, including H5N1. However, experts say that these products cannot kill all viruses, especially influenza A viruses.

Recently, a number of electronics companies have launched air-conditioner models introduced as capable of killing the H5N1 virus. Many salespeople strongly recommend: 'Any kind with an ion symbol is to destroy all' .

As explained by a manufacturer, air conditioners have the ability to 'kill up to 99% of the H5N1 virus in the air' because of a special membrane covered by compounds, including Leuconostoc Citreum, an acid. Lactic is extracted from traditional kimchi. In addition, its air conditioners are also equipped with more effective filters with natural germicidal agents extracted from fish lettuce, silver ion filters .

Another electronics maker that produces air-cooled Plasmacluster technology "capable of controlling up to 99% of the H5N1 avian flu virus activity in the air" explains: "This technology produces more than the Negative and positive ions in ideal equilibrium conditions to kill bacteria, mold, deodorize and stop the allergens. The technology is not only applied by air conditioners but also used to produce refrigerators, air purifiers .

Recently, an electronics company introduced a silver nano technology washing machine, 'capable of 99.9% bactericidal' . This technology produces extremely small silver ions for bactericidal and antibacterial activity up to a month later, making clothes 'pure'.

And Plasma refrigerator of another company advertised as ' killing 400 times more than normal; deodorant ozone gas 10 times; Ultraviolet reduction of 100 times ethylene gas by ozone, negative ion.

According to Vu Lam, in charge of the refrigeration industry of Thien Hoa Electronics Center, most customers now ask if the machine will kill the virus before buying it. Prices of items with bactericidal functions are higher than normal ones with a category of about 500,000-1,000,000 VND.

According to Dr. Pham Thanh Quan, deputy head of Ho Chi Minh City University of Technology's Chemical Technology Department, these technologies are also more or less capable of killing bacteria, but not all, especially H5N1 bird flu virus.

For example, low-temperature plasma technology is used to turn molecules of substances into negative and positive ions, forming electromagnetic radiation to kill bacteria. The theory is that, but to apply, it must be tested, because each type of virus has different decomposition modes. So a product can only control certain types of bacteria and viruses but cannot kill them all.

The ozone generator has bactericidal effect, but is also limited. However, ozone also harms human and animal health such as skin cancer, respiratory disease. As for silver ions, silver does not always exist in ions. Silver is hard to react.

According to Dr. Nguyen Thi Bay, Head of the Department of Pathology of Traditional Medicine Department of Ho Chi Minh City University of Medicine and Pharmacy, fish lettuce trees have only been used to treat hemorrhoids due to antibiotic and hemostatic ability. No studies have shown that this plant is capable of preventing or killing the H5N1 virus. The kimchi of Korean people has a spicy taste, stimulating eating without bactericidal function. Doctor Le Hung, Deputy Director of the Institute of Traditional Medicine in Ho Chi Minh City, also said that no books say kim chi is likely above.

Dr. Tran Tinh Hien, deputy director of Ho Chi Minh City Tropical Hospital, said: "Now scientists do not know exactly whether the virus is transmitted through the respiratory pathway or any other way. If electronic products are "It is too great to kill the bird flu virus. However, it should only be considered an advertisement because there is no evidence or scientific basis . "
