In the absence of smog, do you need an air purifier?

When it comes to air purifiers, people naturally think of haze. Most of the smog is in the winter, so many consumers are used to turning on the air purifier in the winter. In the days of late summer and early autumn, the smog may not be obvious. So, is there no need to use an air purifier during this time?

In fact, air purifiers are mainly used to improve indoor air quality. There are many sources of pollution indoors. Whether it is summer or winter, it is equally polluting. Even high-temperature weather can cause indoor air quality to deteriorate. The problem of indoor air pollution should not be underestimated!

Indoor pollution, speak with data
People spend 70% of their time indoors, while urban residents are as high as 70%-90%. We stay indoors every day, even if it is clear outside, it seems that there is no smog, but the indoor air is still polluted.

According to the World Health Organization’s data in 2016, the number of deaths due to indoor environmental pollution is 2.8 million per year worldwide, with an average of more than 7,671 people per day.

On average, every 12 seconds, one person died due to indoor environmental pollution.

With the improvement of material conditions, people’s home decoration is becoming more and more luxurious, and the possibility of excessive toxic pollutants such as formaldehyde is increasing. In 2014, the China Building Decoration Association published a sample report on the newly installed houses. The results showed that the average formaldehyde over-standard rate was 70%-80%.

Indoor air pollution is 2-3 times more serious than outdoor, and even more than 100 times in some serious cases.

Do you know the three common gaseous pollutants?

Indoor gaseous pollutants caused by decoration, mainly formaldehyde, toluene, and TVOC:

The World Health Organization has classified it as a Class 1 carcinogen. The release cycle of formaldehyde is as long as 3-15 years, especially in the summer, as the temperature rises, the amount of formaldehyde released will be greater.

Toluene is abundantly found in common decorative materials such as paints, paints, and adhesives. Long-term inhalation of toluene may cause fetal malformations, developmental delays, and damage to the nervous system.


TVOC comes from furniture materials commonly found in our homes, household fuels (gas, natural gas), and smoke from cooking. Various components of TVOC have been shown to be carcinogens or suspected carcinogens.
