Ozone generators and ionizers are two different types of air purifiers that are often confused. Ozone generators use a process called oxidation to attack odor-causing gases and permanently remove odors. On the other hand, ionizers, or negative ion generators, reduce particles such as dust and pollen in the air. Ozone is a lung irritant that is produced indirectly by ionizers and other electronic air filters, and directly by ozone generators.
The Food and Drug Administration (FDA) has set a limit of 0.05 parts per million ozone for medical devices. Ozone can be used to reduce odors and pollutants in unoccupied spaces, but the levels needed to achieve this are above those generally believed to be safe for humans. Air ionizers are designed to help provide cleaner air, but they should not be used when people are present in the room. To get rid of the dangers of second and third hand smoking from my roommate, I now plan to keep my ionizer turned on only for 30-40 minutes when no one is in the room, and then turn off the ionizer before anyone comes in. If you're considering buying an air purifier with an ionizing function, it's important to understand the differences between ozone generators and ionizers. Ozone generators attack odor-causing gases through oxidation, while ionizers reduce particles such as dust and pollen in the air.
