Indoor air quality (IAQ) is the quality of the air that we breathe inside our homes, offices, and other buildings. It is an important factor in our overall health and well-being.

Poor IAQ can lead to a variety of health problems, including respiratory infections, allergies, asthma, and even lung cancer.

There are many factors that can contribute to poor IAQ, including:

• Outdoor air pollution: When outdoor air pollution is high, it can seep into our homes and other buildings through windows, doors, and cracks.
• Indoor activities: Cooking, cleaning, and using certain appliances can release pollutants into the air.
• Building materials and furnishings: Some building materials and furnishings, such as carpets, furniture, and paint, can emit harmful chemicals.
• Pets: Pets can shed dander and other allergens into the air.
• Mold: Mold can grow in damp areas of the home, such as basements and bathrooms.

2. Common Indoor Air Pollutants

Most common indoor air pollutants:

• Particulate matter: Particulate matter is a mixture of solid particles and liquid droplets found in the air. It can come from a variety of sources, including car exhaust, smoke, and dust.
• Volatile organic compounds (VOCs): VOCs are a group of chemicals that can evaporate easily. They can come from a variety of sources, including paints, cleaning products, and air fresheners.
• Carbon monoxide: Carbon monoxide is a colorless/ odorless gas. It is mainly produced when fossil fuels are burned. It can come from sources such as stoves, fireplaces, and furnaces.
• Nitrogen dioxide: Nitrogen dioxide is a reddish-brown gas that is produced when fossil fuels are burned. It can come from sources such as cars, trucks, and power plants.
• Formaldehyde: Formaldehyde is a colorless gas that is used in many building materials and furnishings. It can also be found in cigarette smoke and car exhaust.

3. How Air Purifiers Work

Air purifiers work by removing pollutants from the air. They can use a variety of technologies to do this, including:

• HEPA filters: HEPA filters are very effective at removing particulate matter from the air.
• Activated carbon filters: Activated carbon filters are effective at removing VOCs and other gases from the air.
