Introduction

Indoor air pollution is a hazard that can have negative effects on our health. Thus, the use of air purifiers is becoming increasingly popular in households and public spaces. In this experiment, we tested the effectiveness of an air purifier in reducing levels of air pollutants.

Method

We conducted the experiment in a closed room with an area of 20 square meters. To create a polluted environment, we burned incense for 30 minutes and monitored the air quality with a multi-gas detector. After the air quality reached polluted levels, we turned on the air purifier and measured the pollutant levels every 15 minutes for an hour.

Results

The initial air pollutants levels were as follows: PM2.5 – 120 μg/m3, formaldehyde – 0.1 mg/m3, and carbon monoxide – 25 ppm. After activating the air purifier, we observed a gradual decrease in the levels of these pollutants. Within 15 minutes, the PM2.5 level dropped to 50 μg/m3, formaldehyde decreased to 0.03 mg/m3, and carbon monoxide was reduced to 10 ppm. After 60 minutes, PM2.5 levels continued to decrease to 30 μg/m3, formaldehyde was reduced to 0.02 mg/m3, and carbon monoxide was reduced to 5 ppm.

Discussion

The results of our experiment indicate that the air purifier is effective in reducing levels of indoor air pollutants. The significant reduction in levels of PM2.5, formaldehyde, and carbon monoxide within an hour of activation of air purifier, demonstrates its efficiency. The purifier's HEPA filter technology and activated carbon are effective at filtering out pollutants from the air.

Conclusion

Our experiment supports the use of air purifiers as a practical solution for reducing indoor air pollution. It can improve air quality and reduce the risk of health issues related to air pollution. It is also important to note that air purifiers should not be relied upon solely, and appropriate measures to prevent the source of indoor air pollution should also be taken.
