An ozone generator is contained in a housing having a fan for inducing air flow through the housing and over an ozone generating plate where atmospheric oxygen is electrochemically converted to ozone, which flows out of the housing through a grid opening. The ozone generating plate is defined by a glass plate having electrically conductive grids on both sides thereof and each grid is electrically powered to create corona discharge from the conductor; as air and oxygen in the air flows over the plate it is converted to ozone.
