An ozonizer is also known as an ozone generator, and is sometimes mistakenly thought of as synonymous to an ionizer or ionic air purifier. An ozonizer does produce ionized particles, and an ionizer does produce trace amounts of ozone, but the two are not the same. An ozonizer creates ozone by charging the air with a burst of high negative voltage. An ionizer works under the same principle, but primarily produces ionized forms of molecules other than ozone
