Description

Composite air conditioning filter

This creation is about an air-conditioning filter, especially a composite air-conditioning filter that can greatly improve the cleansing effect and is beneficial to the human body.

Due to the deterioration of air quality, the degree of air pollution in the indoor environment is far beyond ordinary people's imagination. There are many invisible pollutants in the air, such as germs, dust, oil fume, dust, smog, pesticides, pollen, and harmful gases. In addition to pollution and odor, these harmful air pollutants can also promote free radicals. Generated, and cause great harm to human health.

Free radicals are groups of atoms that contain an unpaired electron. When atoms form molecules, the electrons in the chemical bond must be paired, so that the free radical will snatch an electron from other substances to form a stable compound. This phenomenon is also chemically It is called oxidation. Biological systems often encounter oxygen free radicals, such as superoxide anion free radicals, hydroxyl free radicals, lipoxy free radicals, nitrogen dioxide and nitric oxide free radicals. Active oxygen free radicals in organisms have specific functions, such as immunity and signal transduction, but too much active oxygen free radicals will cause damage to normal cells and tissues of the body and cause various diseases. In addition, sunlight radiation, air pollution, smoking, pesticides, etc. in the external environment will cause the human body to produce more active oxygen free radicals and cause nucleic acid mutations in the organism. This is the root cause of human aging and disease. For example, the cooking fume produced during cooking contains free radicals, which makes housewives and restaurant chefs who often work in the kitchen much more likely to have lung diseases and tumors than others.

In the case of cars, the equipment materials inside the car will emit toxic gases such as toluene, formaldehyde, ethanol, acetone, butanol, and cars with air-conditioning can be used together to remove dust, sterilize, deodorize, and prevent mold. The air-conditioning filter in the car makes the air in the car clean and makes the user feel more healthy and comfortable. In order to prevent the free radicals formed in the car environment from threatening the health of the user, it is derived to use fragrance or Essential oils are the way to eliminate free radicals.
