- What is indoor air quality (IAQ)?
– Indoor air quality refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.
- Why is indoor air quality important?
– Poor indoor air quality can lead to various health problems, including respiratory issues, allergies, and even chronic conditions such as asthma. It can also affect overall comfort and productivity.
- What are common sources of indoor air pollutants?
– Common sources include tobacco smoke, building materials, household cleaning products, heating and cooling systems, outdoor pollution, mould, and pet dander.
- How can I tell if my indoor air quality is poor?
– Symptoms of poor IAQ include frequent headaches, fatigue, dizziness, coughing, sneezing, and worsening of asthma or allergy symptoms. Musty odours and visible mould growth are also indicators.
- What steps can I take to improve indoor air quality?
– To improve IAQ, increase ventilation, regularly clean and maintain HVAC systems, use air purifiers, minimize the use of products with volatile organic compounds (VOCs), and keep your home clean and dry.
6. Can houseplants help improve indoor air quality?
– Some houseplants can help improve air quality by absorbing pollutants and releasing oxygen. However, their impact is generally limited, and they should not be relied upon as the sole method for improving IAQ.
7. What are volatile organic compounds (VOCs) and how do they affect indoor air quality?
– VOCs are chemicals that can easily become vapours or gases. They are released by products like paints, cleaning supplies, and pesticides. High levels of VOCs can cause health issues such as eye, nose, and throat irritation, headaches, and more severe health effects over long-term exposure.
8. What role does humidity play in indoor air quality?
– Maintaining proper humidity levels (30-50%) is crucial for good IAQ. High humidity can promote mould growth and dust mites, while low humidity can cause dry skin, respiratory irritation, and increased transmission of airborne viruses.
