Due to the continuous increase in smog weather in recent years, the PM2.5 value of many cities has frequently exploded, and the smell of formaldehyde such as the purchase of furniture in new houses is strong. In order to breathe clean air, more and more people have begun to buy air purifiers. Air purifiers can detect and treat indoor air and decoration formaldehyde pollution, and bring fresh air to our interior.

The principle of the air purifier is very simple, that is, a filter is placed in front of the fan. The fan runs to extract air, and the air passes through the filter to retain pollutants, and then discharges high-quality air.

What harmful air is the air purifier mainly useful for?

One: formaldehyde

Because the decoration materials are "not enough", formaldehyde is the biggest culprit of indoor pollution. Formaldehyde raw materials will be enclosed in wardrobes, floors, and paint, and it is a long-term volatilization process. At the same time, harmful pollutants such as formaldehyde and benzene are also high pollutants. The incidence of "acute leukemia" is mostly caused by the family's just decoration.

Two: Second-hand smoke

Second-hand smoke is the second biggest culprit of indoor pollution. In second-hand smoke, there are more than 3000 polluting chemicals. In addition to lung cancer, which is generally considered to be lung cancer, it includes oral cancer, laryngeal cancer, stomach cancer, liver cancer and other malignant tumors; asthma, chronic obstructive pulmonary disease Such as respiratory diseases; coronary heart disease, stroke and other cardiovascular and cerebrovascular diseases; at the same time, second-hand smoke is more harmful to children’s health.

Three: air pollution

The third biggest culprit of indoor pollution is air pollution, which is what we often call PM2.5. The hazard of dust itself is not serious, but it is that PM2.5 particles have large area, strong activity, toxic and harmful substances (for example, heavy metals, microorganisms, etc.), long residence time in the atmosphere and long transportation distance. Human health and atmospheric environmental quality have a greater impact.

Four: pollen

During the period of high pollen incidence, sneezing, runny nose, watery eyes, and nasal congestion are all symptoms of allergies, but the user's allergies are not serious. Skin allergies in children can cause significant changes in mood and behavior, hyperactivity, inability to sit and eat quietly, irritability, fatigue, disobedience, depression, aggressive behavior, shaking legs, lethargy or nightmares, and intermittent speech difficulties.

Five: dust mites

In addition to dust mite allergies, patients with dust mite allergies are also allergic to other substances. Dust mite asthma is a kind of inhalation asthma. The first onset is usually in childhood, with a history of infantile eczema, or a history of chronic bronchiolitis. At the same time, the onset of allergic rhinitis is inseparable from dust mites.

It is precisely because of the existence of pollution sources such as formaldehyde, second-hand smoke, dust, pollen, and dust mites, that air purifiers have the value of use. Therefore, choosing an air purifier is very important! ! !
