Elaine- It all depends on how much ozone your air freshener is putting out. OSHA standards set the maximum concentration (over an 8 hour period) at 0.1 ppm. Older people may have trouble breathing at elevated concentrations. All in all, I would discontinue the use of that machine until you can find out the dose of ozone it puts out. I can find nothing in my literature that supports its use as an air purifier.
