This sanitizing wand has a larger ultraviolet light than the model used for sanitizing toothbrushes. It is intended to be waved over surfaces suspected of harboring bacteria, viruses, or mold. It is operated by pushing a button and has an automatic safety shut-off switch. It is not a toy and should never be aimed at a person but used seriously in areas requiring proper hygiene. It can be used on counters, bedding, and surfaces suspected of harboring microorganisms.
