A gas purifying device is disclosed and comprises a gas purifier and a gas detector. The gas purifier comprises a purifier main body, a filter, an air guiding device and a drive control module. The purifier main body has an embedding slot. The gas detector is assembled in the embedding slot for or detached from the embedding slot for independently use. The gas detector comprises a gas detecting module, a particulate measuring module and a detector drive control module. The gas detecting module comprises a gas sensor and a gas actuator. The particulate measuring module comprises a particulate detector and a particulate actuator. The detector drive control module controls the actuation of the gas detecting module and the particulate measuring module and converts the monitored information from the gas detecting module and the particulate measuring module into a monitored data information, and outputs the monitored data information.

An anion air purifier includes an air quality sensor control module, a high-voltage generator module arranged on a back side of the air quality sensor control module, and an anion generator module arranged on the back side of the high-voltage generator module. The air quality sensor control module includes a plurality of sensing elements arranged therein for sensing air qualities. The high-voltage generator module includes an anode dust arrester upwardly and protrudingly arranged at a center thereof. The anode dust arrester is a round flat hollow structure. The anion generator module includes a plurality of pins arranged thereon for releasing anion. Particles in the air binding with anion will be charged, so as to be attached on the anode dust arrester when flowing thereby and therefore leave clean air flow. Accordingly, it can effectively eliminate particles of the air, release massive clean air, and lower unnecessary ozonized ions.

A covering includes an outer material, a plurality of conductive-fibers, and a fastening material. The outer material includes a front surface and a back surface and the conductive-fibers are disposed between the front surface and the back surface. The conductive-fibers are configured to receive a voltage that causes the conductive-fibers to repel and remove dust from the front surface of the outer material. The fastening material is coupled to the back surface of the outer material and facilitates releasably attaching the outer material to an article.

Systems and Apparatus for a personal ventilation system that provides a personalized column of clean air surrounding a user's space is presented. The personal ventilation system includes an air purifier with a fan and an annular gap downstream of the fan. The annular gap has an inner radius that is within 95% of the outer radius. The annular gap structure allows the air purifier to produce a column of air with an entrainment ratio lower than other commercially available fan. At a distance of 1.5 meters, the air purifier is configured to have an entrainment ratio of lower than 40%. The air purifier also has a removable filter located upstream of the fan. The ventilation system is capable of delivering highly-localized filtered air to a user or location.

A face shield and a face shield monitoring and tracking system, which enables the monitoring of the use of the face shield in real time and the transmission and storage of data and information regarding its use for further management and analysis. The face shield is also equipped with an electrostatic field provided on the surface of a front panel, to attract and retain contaminated droplet particles or aerosols present in the environment.
