What Does Ionizer Mean?

An air ioniser is a device that uses high voltage to ionise air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle. Cations are positive ions missing one or more electrons, resulting in a net positive charge.

What does an ionizer do?

An air ionizer purifies the air in a room by electrically charging air molecules. Many air purifiers use fans and filters to remove contaminants from the air. Air ionizers use ions to remove particulates, microbes, and odors from the air.

Is ionizer good for health?

The Short Answer. Most ionic air purifiers (ionizers) are completely safe and not bad for your health. They emit negative ions into the air as a way to clean it which is harmless to you. They're often confused with ozone generators which emit high levels of ozone that can be bad for health.
