National Pollution Prevention Day 2024: How to Improve Indoor Air Quality Amid Delhi's Pollution - Dr Sachet Dawar

Delhi has been dealing with a major issue of bad air quality for years. In recent months, the problem of air pollution has worsened due to crop burning in nearby states, emissions from industries, construction dust, and pollution from vehicles.

The city’s AQI level is reaching dangerously high levels, causing various health issues including eye irritation, wheezing, and breathing difficulties from extended exposure to the polluted air. There are several strategies that individuals can implement to enhance indoor air quality, thus reducing the negative effects of outdoor pollution.

Here are some beneficial and effective methods to enhance air quality in indoor spaces:

1. Install Air Purifiers

Air purifiers remove pollutants, allergens, and volatile organic compounds (VOCs). Investing in high-quality air purifiers equipped with high-efficiency particulate air (HEPA) filters can be one of the most impactful ways to enhance indoor air quality. To improve their effectiveness, purifiers should be located in frequently used spaces such as the living room and bedroom.

2. Close Windows and Doors During Peak AQI Hours

While fresh air circulation is typically advised for indoor areas, it is suitable to refrain from opening windows when AQI levels are high, generally in the early morning and evening. The best time for ventilation would be during periods when AQI levels are lower.

3. Reduce Sources of Indoor Pollution

Smoking, burning candles, and cooking with open flames are common indoor activities that release pollutants such as carbon monoxide and nitrogen dioxide in the air. These harmful substances can trigger respiratory issues, eye irritation, rhinitis, bronchitis, or sinusitis. The use of electric or induction stoves and low-odour cleaning products, along with the avoidance of indoor smoking and artificial scents, can greatly contribute to a healthier indoor atmosphere.

4. Keep Your Home Clean

Regularly maintaining a clean home is necessary for improving indoor air quality. Dust and allergens can significantly degrade air quality inside a home. Consistent cleaning and vacuuming with a high-efficiency air filter can help to prevent dust assemblage on surfaces and enhance overall air quality indoors.

5. Introduce Indoor Plants

Certain plants have the ability to reduce toxic pollutants present in the air. Specific indoor plants such as areca palm, spider plant, snake plant, and peace lily are known for their air-purifying qualities as they increase oxygen levels while lowering carbon dioxide levels.

6. Establish a “Clean Zone”

Allocating a specific room or area as a “clean zone” can help in increasing exposure to air that is free from toxins. Ensure that this area is equipped with an air purifier and has a healthier atmosphere with less or no allergens.

7. Regulate Humidity Levels

Excessively dry air can heighten the risk of respiratory issues and irritation of the eyes. Using a humidifier can help maintain ideal humidity levels, which in turn prevents associated health complications. It is also essential to clean the humidifier regularly to prevent the growth of bacteria and mould.

The AQI in Delhi fluctuates significantly, particularly in the winter months. To reduce the negative effects of such fluctuations, it is crucial to adopt some strategies that ensure a healthy indoor atmosphere.

Although we may not have full control over outdoor pollution, it is essential to establish a healthy and secure environment indoors to safeguard health amid the pollution challenges faced in Delhi.
