Why Indoor Air Quality Matters<\/div>

The Built Environment as a Health and Accessibility Issue<\/h2>

Indoor environments are where Canadians spend the vast majority of their time. Yet indoor air can contain significantly higher concentrations of pollutants than outdoor air \u2014 from VOCs emitted by cleaning products, personal care products, building materials, and furnishings, to biological contaminants like mould spores.<\/p>

For people living with MCS, asthma, COPD, or rhinitis, these exposures can determine whether a person can enter, remain in, or meaningfully participate in a space. Climate change is increasing reliance on indoor environments, while energy-efficient building design reduces natural air exchange \u2014 concentrating pollutants in tighter spaces.<\/p><\/div> \t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
