Ionizing air purifiers are highly effective at disinfecting air, but they should be used with caution. Ozone, which is found in the Earth's protective layer, is beneficial in filtering out harmful ultraviolet radiation from the sun. However, when it is emitted into the air we breathe, it can be hazardous to our health and the environment. Studies have shown that air is not purified with safe levels of ozone, since it cannot oxidize air pollutants to this level.
Most room ionizers produce hazardous levels of ozone and create a higher concentration in the room. Fortunately, some room ionizers have built-in controllers to prevent ozone levels from exceeding safe limits.Continuous exposure to ozone can also attenuate the sense of smell. With conflicting data surrounding ionizers, I usually keep my ionizer option turned off. I have a Therapure TPP300D with UV+ ionizer that turns on for 8 hours in my living 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.Air ionizers are designed to help provide cleaner air and they do so through the use of ionized particles. Generally speaking, ionizers are not energized enough to be harmful to you. As more information is disseminated about the potential dangers of air ionizers, consumers will be better informed before purchasing an air purifier and will be able to avoid these potentially hazardous systems.
