Why do we say that winter and summer are the seasons with the most serious indoor pollution?

Because summer is hot and air conditioners are on all the day. In winter, it is cold and the doors and windows are closed tightly. Warm environment + dust in the air + formaldehyde released from floor and furniture + possibly pet hair and bacteria, as well as carbon dioxide and other odors exhaled by people staying indoors for a long time ......

Because of the hot summer, the air conditioners are all turned on. In the cold winter, the doors and windows are tightly closed. Warm environment + dust in the air + formaldehyde released by floor furniture + possibly pet hair and bacteria, as well as carbon dioxide and other odors exhaled by people who stay indoors for a long time...

The doors and windows have been closed for a long time, and the smell of the room is the product of a mixture of various pollutants.

Doors and windows closed for a long time, there will be smell in the room, the result of a variety of pollutants mixed.

We have about 80% of the day is spent indoors, especially at night sleep, the air conditioning or floor heating of the home, a long time without ventilation. The indoor pollutants can not be removed. To fix these problems, we only need an air purifier. If outdoor pollution is not particularly polluted, we can open a small slit for ventilation at night, which can solve the lack of ventilation.

How do you know if the air at home is goodor not?

①　Frequent and very easy to catch colds;

②　Itchy nose, sneezing, runny nose, and frequent coughing;

③　Non-smokers feel uncomfortable in their throats, foreign bodies, and poor breathing;

④　Chest tightness, coughing, dyspnea, etc.;

⑤　Having skin allergies and other symptoms, and it is group-like;

⑥　Feeling bored, nauseated, or even dizzy when getting up early in the morning;

⑦　Indoor plants are not easy to survive, the leaves are especially prone to yellowing and withering, especially some plants with strong vitality are also difficult to grow normally;

⑧　There is a disease in the family, but after leaving this specific environment, the symptoms have changed and improved significantly;

If any of these situations please pay more attention to whether the air quality at home has gone wrong.

1. Human breathing, smoke.

The human body produces more than 500 chemical substances in the process of metabolism, and the smell and pathogenic bacteria emitted by the human body's breath cannot be ignored. The cells shed from human skin account for about 90% of the air dust. If there are pets in the home, the pollution concentration will be even higher. Tobacco contains more than 40 carcinogens, which is the "number one killer" of human health. Second-hand smoke has an even greater impact on pregnant women and children.

2. Decoration materials, daily necessities

The use of various paints, paints, wall coverings, adhesives, artificial boards, marble floors and newly purchased furniture for interior decoration will emit phenol, formaldehyde, toluene, asbestos dust, radioactive substances, etc., which can cause people to have headaches, insomnia, Reactions such as dermatitis and allergies make the body's immune function decline.

3. Microbes, viruses, bacteria

Microorganisms and fine dust mostly exist in warm, humid and unclean environments, and they are dispersed in the air along with dust particles, becoming allergens and ways of spreading diseases. In particular, dust mites are an allergen of human bronchial asthma. Dust mites like to live in the dust in the room. Spring and autumn are the most vigorous growth and reproduction periods for dust mites.

4. Kitchen fume

In the past, people paid little attention to the pollution of kitchen oil fume to indoor air. According to research, there is an increase in lung cancer among urban women. Most of the patients diagnosed as adenocarcinoma by hospitals are a type of lung cancer that is rarely linked to smoking. Further investigation found that the carcinogenic pathway is related to the mutagenicity caused by kitchen oil fume and the mutagen of high-temperature edible oil oxidation and decomposition. Another major source of pollution in the kitchen is the burning of fuel. In the case of poor ventilation, the concentrations of carbon monoxide and nitrogen oxides produced by burning appliances far exceed the limit values stipulated by the air quality standards. Such concentrations will inevitably cause harm to the human body.

5. Air Conditioning Syndrome

People who work in an air-conditioned environment for a long time often feel bored, fatigue, lethargy, muscles
