Will Casino Queen air be hurt by smoking ban?

What a questionable difference in air qualtiy this smoking ban makes! The Casino Queen air filtration system had previously almost entirely removed tobacco smoke from the air. Now that no one can legally smoke in the Queen, I am sure that the excellent air filtration system will be turned off to save money. From now on, patrons and casino workers will breathe toxins and pathogens previously removed from casino air. What kind of public health benefit is that?
