A method for isolating the breathing of vehicle occupants involves activating an ultraviolet radiation source to sterilize the air. A first sensor detects the carbon dioxide content of the air. A second sensor detects the air quality. A third sensor detects particles in the air. The reading from the first sensor is compared to a reference carbon dioxide reading recorded by a controller connected to the sensors. The fan speed increases the duration of the air's exposure to ultraviolet radiation. The reading from the second sensor is compared to the reference air quality recorded by the controller. A signal is sent to a display that includes the filtration system to identify airborne contaminants. The reading from the third sensor is compared to the reference particles recorded by the controller. An alert is sent to a relevant party indicating the presence of airborne particles.

The invention discloses an MOCVD (Metal Organic Chemical Vapor Deposition) reaction chamber reset pretreatment method based on a magnesium coating and aeration air, and aims to solve the technical problems of long false plating time required by reset and low brightness of an epitaxial wafer of a first furnace due to the fact that parts in a reaction chamber adsorb impurities after furnace disassembly and maintenance of MOCVD equipment. The method comprises the following core steps: firstly, introducing magnesium source gas into a maintained reaction cavity at a high temperature, so that magnesium atoms are adsorbed and permeated into micropores in the surfaces of components such as a graphite disc and the like; then, the temperature is reduced, air or other oxygen-containing gas is actively introduced into the reaction cavity, the adsorbed magnesium is promoted to react with oxygen, a compact and stable magnesium oxide passivation layer is generated in situ, and therefore residual impurities are effectively blocked. By adopting the method for pretreatment, the machine reset time can be remarkably shortened, the waste of an expensive MO source is greatly reduced, and the brightness of the first furnace epitaxial product after maintenance can reach the mass production standard.
