Safe Use of Electronic Air Cleaners This type of air cleaner has come u nder fire recently, due to the ozon e that is produced as a by product of the electrostatic process. Ozone is considered a pollutant and high levels of ozone in the air in your home can be an irritant. It is par ticularly a problem for people who suffer from asthma or other respira tory or lung disorders. To reduce the risk associated with ozone, consider running the air cle aner when the room is not in use. F or example, run the system in your bedroom in the early evening. Turn it off about an hour or so before y ou plan to go to sleep. Run the mac hine in the kitchen or other living areas at night and turn it off fir st thing in the morning. This will allow the ozone in the air to dissi pate before you enter the room. If your system has a high and low s etting, run it on the low setting. If odor is a problem, run it on hig h when the room is empty and air ou t the room before you enter it. Whe n the room is occupied, use only th e low setting. A separate hepa filt ration system can help remove some of the excess ozone in the air.
