Indoor air quality, or IAQ, is a critical aspect of our health and well-being, especially for homeowners and business owners. Understanding what are the 5 main factors that affect indoor air quality can help you take the necessary steps to improve the air you breathe indoors.
In this article, we will delve deep into these five main factors, which are crucial in maintaining a healthy indoor environment.
1. Ventilation
Proper ventilation is essential to maintaining good indoor air quality. It helps in the removal of pollutants, reduces humidity, and introduces fresh air into the indoor environment.
Natural Ventilation
Natural ventilation involves the use of windows, doors, and other openings to allow fresh air to circulate indoors.
Mechanical Ventilation
Mechanical ventilation systems include exhaust fans, air conditioning units, and air purifiers, which help in circulating and filtering indoor air.

2. Indoor Pollutants
Indoor pollutants are contaminants that come from various sources within a building. They can significantly impact indoor air quality.
Common Pollutants
Some common indoor pollutants include dust, pet dander, mold spores, pollen, and VOCs (volatile organic compounds).
Sources of Indoor Pollutants
Sources of indoor pollutants can be furniture, cleaning products, building materials, and human activities such as cooking and smoking.

3. Humidity Levels
Humidity levels play a vital role in indoor air quality. High humidity can lead to mold growth, while low humidity can cause respiratory issues.
Managing Humidity
Using dehumidifiers, air conditioners, and proper insulation can help in managing indoor humidity levels.
Effects of Imbalanced Humidity
Imbalanced humidity levels can cause health issues like allergies, asthma, and other respiratory conditions.
4. Temperature Control
Temperature control is another key factor in maintaining good indoor air quality. Extreme temperatures can affect both comfort and health.
Thermal Comfort
Thermal comfort is achieved when the indoor temperature is within a range that feels comfortable for the occupants.
Impact of Poor Temperature Control
Poor temperature control can lead to discomfort, increased stress levels, and even health problems.
5. Building Materials and Furnishings
The materials and furnishings used in a building can also affect indoor air quality. Some materials may release harmful pollutants over time.
Impact of Building Materials
Building materials such as paints, adhesives, and carpets can emit VOCs, which are harmful to human health.
Choosing the Right Materials
Opting for eco-friendly and low-VOC materials can help in improving indoor air quality.
