Back when I was still a bachelor, I would always host a bi-weekly poker game for that eight-week stretch between the Super Bowl as well as the start of baseball season.
One of the players had to insist on smoking a cigar and he easily preferred an “old stogie” over a Bolivar Royal Corona.
It would take such a long period of time for the tobacco odor to fade. The solution was pretty much a smokeless ashtray where a tiny fan would suck the smoke into a mini pouch with a filter as well as activated carbon! While not the finest solution around it was a pretty huge improvement. I actually didn’t know I was using a rudimentary source capture system to work on keeping the air clean. Central Heating as well as Air Conditioning machines in residences as well as office buildings are actually designed to provide fresh as well as clean air to whole rooms… Air that is in a single room can be moved to another room with the air duct. This is not a complication in homes, however it is in your doctor’s office where patients regularly sit for long periods. With Covid-19, it is perfectly clear to see that the pandemic has affected doctor offices on a global basis. In the U.S., the CDC recommends “the use of a portable, high-efficiency particulate air (HEPA) air filtration machine while the patient is undergoing, as well as immediately following, an aerosol-generating procedure” in a doctor office setting. Other methods to return confidence in doctor offices are Ionizers, ozone generators for cleaning everything on unoccupied spaces, as well as carbon filters. Another system acts the same as a laboratory or kitchen “hood” that essentially sucks up air directly from the source, and is known as a “source capture system”. These systems are a relatively massive improvement over that smokeless ashtray that our cigar smoking neighbor used during those poker games back then.
