　　In the hot summer, dryness and heat have become a major feature of life, but the air pollution problem we have been chasing has always existed. Therefore, as far as air purifiers are concerned, it is still of great help to us. In addition to inhalable particulate pollution and harmful gases, the air pollution problems encountered in our daily life are also a part of biological pollution that cannot be ignored. In the indoor environment, the main causes of biological pollution include bacteria, fungi, allergic viruses and dust mites. There are many kinds of biological pollutants, which is one of the major indoor air pollution phenomena that people face, and even most of the diseases caused by air pollution are related to biological pollution.

　　At present, the causes of indoor air pollution that cause indoor environmental pollution such as office buildings and homes, and cause health damage such as allergic diseases or respiratory diseases include the following:

　　1. Mold

　　Mold is a microorganism that can multiply rapidly in warm and humid environments and is the causative agent of the most air pollution-related diseases. Mold in the air can cause nausea, vomiting, abdominal pain and other symptoms, severe asthma, dysentery and so on. According to a study by Austin in the United States, in adults, asthma caused by various molds is the sum of other factors, and the probability of death is more than twice that of other factors.

　　2. Dust mites

　　Dust mites are one of the most common airborne microscopic organisms and are small arthropods that are difficult to detect with the naked eye. Dust mites are one of the main culprits of allergic diseases and multiply rapidly in indoor environments. In particular, the extensive application of carpets, wallpapers and upholstered furniture is conducive to the reproduction and growth of dust mites. According to indoor environmental monitoring data, in general, there are at least 10,000 dust mites blown out by air conditioners, which can cause allergic dermatitis, rhinitis, chronic urticaria and other diseases after entering the human body through air flow.

　　3. Legionella

　　Legionella is a kind of bacteria, which mainly exists in water and soil. Although Legionella is not transmitted through the air under normal circumstances, if the room is too humid, Legionella will enter the body through the sol mist in the indoor air, causing the body to heat up, accompanied by chills, muscle pain, headache, chest pain, Difficulty breathing, etc.

　　4. Animal dander or other biologically active substances

　　In recent years, pet feeding has gradually become a trend, but the resulting pet dander and other related air pollutants with biologically active substances have seriously affected people's health. When there are pets indoors, the content of allergens in the air will also increase. According to the survey, about 15% of the general population have allergic reactions to allergens of cats and dogs. Therefore, the incidence of allergic diseases such as asthma and allergic rhinitis is greatly increased in families who keep pets.

　　The air purifier has the functions of filtering out dust, eliminating odors and harmful gases, double sterilization, and releasing negative ions. It circulates the indoor air through the motor, and the polluted air passes through the air filter in the machine to remove or adsorb various pollutants, and then passes through the negative ion generator installed at the air outlet to continuously ionize the air and generate a large number of negative ions. It is sent out by the breeze to form an air flow of negative ions to achieve the purpose of cleaning and purifying the air.
