The best way to remove aerosols created by dental procedures is to create a stream of air focused close to the source. Source capture as it’s known is more efficient since we’re pulling a concentrated source of contaminants. Each unit of air that you are paying for “works harder” in this manner.<\/p>\n\n\n\n

From this point, there are 2 choices: exhaust the air, or recirculate it. Here’s a list of pros\/cons for each system.<\/strong><\/p>\n\n\n\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t
