If your home is newly renovated, the home will be filled with harmful gases such as formaldehyde, benzene, toluene, and a pungent smell.

Or if your home is next to the road, then you will definitely not open the windows often, because the outdoor air is dirtier than the indoor air, but how can you keep the indoor air fresh? Air!

Or you have babies, pregnant women or patients with respiratory diseases in your family, have you found that they are particularly sensitive to air pollution and have a great demand for fresh and sterile air!

If you ignore the above problems, then the air purifier is 100% necessary for you. Because the air purifier can remove harmful gases such as formaldehyde, benzene, toluene and other decoration residues; it can remove odors and at the same time achieve the effect of sterilization, disinfection and mites.

According to statistics, people spend about 70% of their life indoors, and the average daily inhalation of air is 12 cubic meters, while urban residents spend about 70%-90% of their time in various indoor environments every day. Therefore, air quality is critical to human health. We can see the clean floor, shiny furniture, transparent glass... but we cannot know whether the indoor air is clean or not. In fact, every living space may hide invisible air pollution. According to the World Health Organization (WHO) report, nearly half of the world's people are exposed to indoor air pollution.

Three types of indoor air pollution:

I. Biological pollutants


Small size but wide spread, fast speed, easy to cause allergic reactions such as sneezing, eye discomfort, coughing, wheezing. The number of bacteria and viruses is huge, and they spread widely at an extremely fast rate, which is easy to cause a variety of diseases. Fungal spores can easily spread and multiply in the air in humid and warm areas, and long-term exposure can easily cause allergies and asthma.

Dust, dust mites, dust is uncomfortable to breathe and is a breeding ground for dust mites and fungi. Dust mites are small insects that often grow on mattresses, sheets and furniture or are suspended in the air, increasing the chance of asthma. Flowers outdoors and even in vases produce pollen, which can cause obvious discomfort to the respiratory tract, eyes and skin if inhaled by allergic people. The hair and dander of pets and humans are very small, which can easily enter the human respiratory system and provide favorable conditions for the reproduction of dust mites and fungi.

Second, odors

From pets, cooking, garbage and human body. Odors are unpleasant, affecting home life and the environment of the neighborhood.

Three, chemical pollutants

From cigarettes, decoration projects, cleaning supplies and furniture, prolonged contact can stimulate the skin, nerves and respiratory tract, bringing health risks.

Secondhand smoke

It has been identified as a human class A carcinogen by the US Environmental Protection Agency and the International Agency for Research on Cancer. It contains hundreds of toxic substances and carcinogens such as carbon monoxide and formaldehyde. , especially for children whose lungs are still developing.


From everyday furniture plywood, pressed board, urea-formaldehyde resin products and floors, it is classified as a harmful carcinogen. High concentrations of formaldehyde can irritate the eyes, nose and respiratory system, and even cause asthma in severe cases.

Benzene series compounds

include benzene, toluene, xylene, etc., some of which are identified as carcinogens by the World Health Organization. Mainly from various building materials organic solvents, such as paint, coating additives and wallpaper, carpets, synthetic fibers and so on. Long-term exposure can cause chronic poisoning, neurasthenia and hematological symptoms. In severe cases, aplastic anemia, even leukemia, and death may occur.

Radon gas

comes from soil, rocks, and granite. Radon gas is colorless, odorless, and difficult to detect. The decay products of radon gas will accumulate in the lungs. It is the second source of lung cancer, ranking second only to smoking.

Air purifiers, also known as 'air cleanersAir pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), products that effectively improve air cleanliness, are mainly divided into household, commercial, industrial, and buildings.

The air purifier is mainly composed of a motor, a fan, an air filter, an ion tube and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air inside the machine. After the air filter, various pollutants are removed or adsorbed. Some types of air purifiers will also install a negative ion generator at the air outlet (the high voltage in the negative ion generator generates a DC negative high voltage during operation) to continuously ionize the air. , produces a large number of negative ions, which are sent out by the micro fan to form an air flow of negative ions to achieve the purpose of cleaning and purifying the air.
