Study Finds High Air Pollution in Homes

Earlier this year, the University of Birmingham released a report revealing that air pollution levels in homes can be higher than those found outdoors. The study, titled “Using Low-Cost Sensors to Assess Common Air Pollution Sources Across Multiple Residences,” monitored particulate matter in three urban households in Birmingham. Common sources of indoor particulate matter include dust, cooking, incense, and scented candles. 

This finding aligns with research conducted by our recent intern, Pooja Jani, who identified harmful compounds from sprays used in furniture cleaning and cosmetics, as well as issues related to mould and allergens. She noted that indoor air quality can also be adversely affected by external factors such as construction activities and traffic emissions. 

Separately, local authorities are conducting studies of their own to understand the impact of poor indoor air quality. Last year, Westminster City Council (our accountable body) received funding from the Mayor’s Air Quality Fund to use advanced indoor air quality monitors to explore the connections between indoor air quality, health, and socio-economic disparities. 

Understanding the relationship between indoor air quality and health is essential, especially since most people spend most of their time indoors—whether at home, work, school, or in shops. The University of Birmingham’s study highlights how indoor air pollution can impair our ability to concentrate. 

The report provides several recommendations for reducing indoor pollutants, including: 

• Opening windows 
• Regularly dusting surfaces 
• Using extractor fans while cooking 
• Reassessing how your use of scented candles 
• Utilising air purifiers  

By taking these simple steps, we can create healthier indoor environments and enhance our well-being. Prioritizing indoor air quality is an important move towards better health and productivity for everyone.
