Microbiology: Do negative ions kill fungi, bacteria, viruses and dust mites? How effective are these  devices?
That's interesting. How effective are the devices that produce negative ions?
The effectiveness of negative ion devices can vary depending on several factors such as the size of the device, the concentration of negative ions it produces, and the environment in which it is used. However, studies have shown that properly designed and used negative ion generators can significantly reduce the concentration of airborne microorganisms in indoor spaces.
