The outdoor smog is so serious, is the indoor air quality safe?

The outdoor smog is serious, so it will be safer to close the door. This is a wrong understanding.

In fact, according to the statistics of the Environmental Protection Agency, indoor air pollution is five times more serious than the outdoor average. Nearly 4 million people die prematurely every year because of indoor air pollution.

1, indoor number one killer "formaldehyde". According to authoritative experiments, formaldehyde exists not only in newly renovated houses, but also in old houses for many years, and the volatilization period of formaldehyde is even as long as 10 years. The volatilization of formaldehyde is affected by temperature, and summer is the high season of formaldehyde release.

2. The toxic and harmful gases produced by gas stove combustion and indoor smoking are also important factors that seriously threaten health.

3. Radioactive substances The cement, marble and other materials used in building construction contain radon, which is a substance that can release radioactive pollution and is particularly harmful to human body. Don't blindly pursue luxury decoration when decorating. The more complicated the decoration design, the more main materials and auxiliary materials are used, and the greater the possibility of pollution.

4. Bacteria breeding in refrigerators and refrigeration systems, fungi breeding in air-conditioning filters, and dust mites growing in dust are all hidden dangers that affect health. We must pay attention to develop hygienic habits, clean the refrigerator regularly, and remove the filter before using the air conditioner to avoid bacterial pollution.

In order to reduce indoor air pollution, it is necessary to master the correct ventilation method of opening windows, avoid traffic peaks and dust, and open windows for about half an hour every day. Try not to stir-fry when cooking, and it is best to control the oil humidity below 200 degrees. In addition, more green plants with strong adsorption such as green radish and chlorophytum are planted indoors.

In short, do a good job in indoor cleaning and personal hygiene, maintain indoor air quality, and if possible, it is best to choose a professional air purifier to reduce the negative impact of bad air environment on the body.
