This creation is about an air conditioner filter, especially a multi-effect protective air conditioner filter that can greatly improve the cleaning effect and is beneficial to the human body.

As the deterioration of air quality is becoming more and more serious, the level of air pollution in the indoor environment is far beyond the imagination of ordinary people. There are many pollution particles invisible to the naked eye in the air, such as germs, dust, oil fume, dust, smoke, pesticides, pollen and harmful gases. generation, and cause great harm to human health.

A free radical is an atomic group containing an unpaired electron. When an atom forms a molecule, the electrons in the chemical bond must be paired, so that the free radical will capture an electron from other substances and form a stable compound. This phenomenon is also known in chemistry. called oxidation. Oxygen free radicals are often encountered in biological systems, such as superoxide anion free radicals, hydroxyl free radicals, lipid oxygen free radicals, nitrogen dioxide and nitric oxide free radicals. Active oxygen free radicals in the body have specific functions, such as immunity and signal transduction, but if too many active oxygen free radicals will lead to damage to normal human cells and tissues, and cause a variety of diseases. In addition, sunlight radiation, air pollution, smoking, pesticides, etc. in the external environment will cause the human body to generate more reactive oxygen species and mutate nucleic acid in the organism, which is the root cause of human aging and disease. For example, the cooking fumes from cooking contain free radicals, making the risk of lung diseases and tumors much higher than others for housewives and restaurant chefs who often work in the kitchen.

Taking a car as an example, the equipment materials in the car will emit toxic gases such as toluene, formaldehyde, ethanol, acetone, butanol, etc., and the car with air-conditioning can be used together with the functions of dust removal, sterilization, deodorization, and mildew prevention.
