During my bachelor times I would host a weekly poker game for the two month space between the Super Bowl plus the start of baseball season.
One of the players had to insist on smoking a cigar plus his option of cigars was honestly closer to an “old stogie” than a Bolivar Royal Corona. It easily would take days for the tobacco stench to fade away. The solution was a smokeless ashtray where a tiny fan would suck the smoke into a small pouch with a filter plus a good amount of activated carbon. While not perfect it was a pretty major improvement. I honestly didn’t know I was using a rudimentary source capture system to wash the air. Central Heating plus Air Conditioning appliances in dwellings plus office buildings are actually designed to deliver fresh plus scrubbed air to whole rooms. Air that is in a single room can be easily pushed to another room through the ductwork system. This is not a problem in homes, but it is in your healthcare professional office where patients kneel with their mouths open for lengthy periods. With Covid-19, it is actually clear to see that the pandemic has affected healthcare on a global basis. In the U.S., the CDC suggests “the use of a portable, high-efficiency particulate air (HEPA) air filtration appliance while the patient is undergoing, plus immediately following, an aerosol-generating procedure” in a healthcare professional setting. Other methods to restore confidence in healthcare professional offices are Ionizers, ozone generators for disinfection on unoccupied spaces, plus carbon filters. Another option acts the same as a laboratory or kitchen area “hood” that easily pulls up air from the source, which is easily known as a “source capture system”. They are a fairly huge improvement over that smokeless ashtray that my cigar smoking pal used during those enjoyable poker games.
