How to control indoor air quality?

Growing urbanization has forced people to spend up to 90% of their time indoors, in their homes, or in other spaces like work. Therefore, thinking about the quality and control of indoor air becomes crucial for human well-being.


This concern increased by the fact that indoor pollution is 1,000 times more likely to enter the lungs than outdoor air pollution. Over the past decade, some studies have shown that domestic air pollution is the most important environmental cause of death worldwide, with between 3.8 to 4.3 million premature deaths each year, and almost half of it occurred in India alone.

Usually, this type of pollution is linked to indoor emissions from the combustion of fossil fuels for cooking, heating or lighting, but probably to other factors that are less well known.

In the following we provide some advice on controlling the quality of domestic air.

How to control indoor air quality?

1- Source control

Source control is the first step because it is the most effective by eliminating or reducing individual sources of pollution. This control is a profitable approach in terms of protection and energy cost.

So try to adjust the amount of emissions from gas stoves, for example, and turn them off when you don’t need them.

2- Improve ventilation

To reduce the concentrations of pollutants in the ambient air inside there is only one solution: increase the quantity of outside air entering the interior through the window opening or operate window fans. or attic. But be careful, check the air quality outside beforehand, especially if you live by a road with heavy traffic or near an industrial area.

Do not rely on the mechanism of home heating and air conditioning systems, including forced air heating systems, most of them do not mechanically bring fresh air indoors.

3- Use exhaust fans

Install and use fans often in kitchens to remove cooking fumes and in bathrooms to remove steam.

4- Place a doormat

Wiping shoes can reduce the pollutants carried into the home that usually spread in the air. 


5- Install air cleaners

The effectiveness of an air cleaner depends on how well it collects pollutants from indoor air and how much air it draws through the cleaning or filtering element. 

There are many types of air cleaners/purifiers on the market. Some are very effective at removing particulates, while others, including most table-top models, are much less so, so they are generally not designed to remove gaseous pollutants.

6- Avoid anything that “smells good”

Avoid scented items, including deodorants and scented candles, which cause more asthma.

7- Minimize the carpet

Carpets and rugs are known for their ability to capture pollutants such as dust mites, animal dander and mold spores. So, opt for hard-surface flooring instead.

It is especially important to take as many of these steps as possible especially if you are involved in activities like painting, heating with kerosene heaters or maintenance by welding, brazing or sanding.
