We do. If I had to guess, I would say that, for this room two and a half years ago, between meetings—assuming you were having meetings—someone would come in after a meeting at eight o'clock at night, don his garb and put on all his PPE, if he was smart. He would spray the entire room with sanitizers. The product would go into the air and then land on a surface. Theoretically, it would disinfect or sanitize the surface. The amount that was done during that period was incredible, the amount of rooms and stuff. There were still people doing it a couple of months ago.
What I read in the Gazette said that for now the air sanitizing was going to be put aside. There is only so much anyone can do at one time. I just wanted to urge people that it's a definite issue, and that if it comes up again, should we get something like that, people are going to want to do the same thing.
On the filtration, the units that we and other people sell for filtering the air do a great job, not just for COVID or something like that but to improve the quality of the air that we all breathe. I think the air filtration is a positive thing that has come out. The other is a real thing: People are going to want to spray rooms again if they think there are people inside who have had COVID or whatever it is.
