Ultra-fine and fine particle formation as a result of chemical reactions between ozone and fourdifferent air fresheners and a typical lemon-scented domestic cleaner was studied in a fullyfurnished, naturally ventilated office. The study showed that under conditions representativeof those occurring in such offices, air fresheners or scented cleaners may react with ozone toform secondary organic aerosols (SOA). The tested air fresheners were relatively smallsources of SOA with detectable increases occurring only in the ultra-fine particle numberconcentration. With the cleaner, also an increase in particle mass was observed.
