In Helsinki metropolitan area, , the adult population spends nearly 87 % of their time in indoor environment.Thanks to mechanical ventilation systems with supply air filtering, indoor concentrations of ambient particles associated with health risks can be minimized. That study has quantified the effects of those reductions of concentrations on population exposures.
