Residential indoor air quality is a critical aspect of maintaining a healthy and comfortable living environment. It refers to the purity and cleanliness of the air within homes, which can be influenced by factors such as pollutants, allergens, humidity levels, and ventilation. Poor indoor air quality can lead to various health issues, including respiratory problems, allergies, and exacerbation of existing conditions like asthma. To improve indoor air quality, homeowners can implement several measures, including regular cleaning and dusting, proper ventilation, and the use of air purifiers and filters. Additionally, controlling humidity levels and minimizing the use of household chemicals can further enhance air quality. Investing in quality HVAC systems with air quality features and scheduling professional indoor air quality assessments can also help ensure a healthier and more comfortable living environment for residents.
