Does anyone have experience with ionisation of indoor air

Searching the web for air ionizers will return little substance. What you'll find is marketing hype from manufacturers of in-room ionizers.
Ionization can charge particles, but unless these charged particles are captured on a media filter within a forced air system, the particles will attract to and settle out on walls and other surfaces. Settling out of airborne pathogens will reduce their airborne counts (and has been used extensively in animal husbandry for infection control see but has little to do with sterilization or inactivation of these pathogens(see
What's important about "ionization", as it pertains to microbial control, is the production of non-thermal plasmas. Below are some suggested readings. You may need to go to a University research library to find these. If you have trouble, let me know and I can send you hard copies. (drender@strionair.com)
