Lewis wants to know:

Ions in the air move to particles by Brownian motion, and then the particles are removed from the air by electrostatic attraction to surfaces. The particles include dust, smoke, viruses, bacteria, allergens and radioactive particles, from visible size down to sub micron nanometer size. There is evidence that viruses and bacteria are killed by this process as well as removed. To me this means that ionisation is to air as chlorination is to water. Charge dispersal by ion wind means that room sized volumes of air can be ionised by unfanned charged needle devices dissipating micro-amps of electric ion current into the air, and consuming microwatts of power, at least for that direct purpose. So these extraordinary claims require extraordinary evidence. Yet the research has been done, the devices are available, but somehow my local hospital does not seem to have ionisers. Please help, or prove this argument wrong.

Can you help?

Makes sense to me
