Yes, salmonella can be airborne, but the main sources are in poultry houses, where is becomes airborne from dust contaminated with feces.
The site you quote for "negative Ion Generators" is a pseudo-scientific sales pitch, AKA snake oil salesmen of the 21st century.
BTW, "negative Ion Generators" would be more appropriately called Ozone generators. Ozone at ground level is a BAD thing, unless being used for a specific purpose, such as using it as PART of an antimicrobial filter system.
