It is effective in removing formaldehyde.
Reactive oxygen, also known as triatomic oxygen, is a strong oxidant that can kill a wide range of microorganisms, including bacteria, spores, viruses, fungi, etc. Its killing speed is 600-3000 times faster than chlorine. High concentrations of active oxygen can react with formaldehyde and other components in the air to generate carbon dioxide, water and oxygen, effectively sterilizing and removing formaldehyde. Many purifiers and air conditioners use active oxygen technology.
