“In North America, people tend to spend more than 90% of their time indoors, and this percentage likely increases with age as people become more homebound,” observes Diana Anderson, a clinical fellow in geriatrics at UC San Francisco, a medical doctor, and an architect. “Older adults may be especially susceptible to effects of low concentrations of pollutants due to a number of underlying chronic diseases,” she says.
Anderson notes that aged lungs tend to have less capacity, elasticity, and filtering power against pollutants than their younger counterparts. “Older adults have an increased occurrence of acute respiratory symptoms and reduced lung function. This emphasizes the importance of good indoor air quality [IAQ] for health.”
Access to fresh outdoor air is also highly desirable, she points out, as is the use of HEPA filtration to address indoor particulates. HEPA stands for high efficiency particle arrestance, largely considered to be the highest level of protection.
