News Desk: In the ongoing lockdown, everyone has to spend a lot of time at home. Contaminated air inside the house has a detrimental effect on the body. Dhaka also tops the Air Quality Index (AQI) survey.

A study by Artemis Hospital, part of the Clean Air India Movement, found that an unhealthy home environment was responsible for 31 percent of airborne illnesses. Indoor air pollution can cause allergies, asthma, rhinitis, dysonia, and complex lung diseases.

Meanwhile, experts say the air quality in Dhaka city is ‘very unhealthy’ and everyone is at serious health risk.

On the other hand, a recent study has found that indoor and outdoor air in Dhaka is almost equally polluted. Many people keep their doors and windows closed, thinking that dust will enter the house. However, since the outdoor environment is completely open, the air quality is often better than indoors. The carbon dioxide, various gases, and dust emitted by the breathing of multiple people living in a closed indoor environment reduce the quality of indoor air.

In this case, you can install an air purifier in the house to breathe in the sterile air. The main function of an air purifier is to clean the tiny particles, harmful gases and germs inside the house. It contains activated charcoal (coal) which removes foul smelling gas like ammonia.

Purifiers ensure comfortable fresh air in a very short time due to the presence of three-way air flow technology. Due to their high-powered sensors, they are easily able to detect microbes, such as PM 2.5 micrometers, including dust and gas. The indoor air quality is also known through the display of digital purifier.
