A sanitizer with an ion generator and ion electrode assembly are provided. The ion generator is configured to generate ions using an AC voltage and an ion electrode assembly. The ion electrode assembly includes at least one emitter unit adapted for attachment to the ion generator. At least one ion source is attached to the at least one emitter unit for emitting ions. An emitter cover that is flexible has a thickness and extends from a proximal end to a distal end and defines an inner surface and encloses the at least one emitter unit for protecting the at least one ion source and the at least one emitter unit. The inner surface of the emitter cover is in a spaced relationship with the at least one ion source to define an air gap.
