Abstract: An air purifying system includes an air purifier mechanism, a controller, and a sensing device. The sensing device is configured to measure an air quality parameter of the air entering the housing via the air inlet to generate inlet air quality data, and to measure an air quality parameter of the purified air exiting the housing via the air outlet to generate outlet air quality data. The controller is configured to: receive the inlet air quality data and the outlet air quality data, compare the inlet air quality data and the outlet air quality data with their corresponding predetermined threshold ranges, and determine an action to be taken.

Abstract: The invention disclosed herein is an improved panel arrangement for closing a box. The invention includes two sliding panels and two slotted panels, each slotted panel having a first slot and a second slot for receiving a terminal edge of a sliding panel. In some embodiments of the invention, a flap or flaps are present about a perimeter edge of the slots to allow better access to the slots by the terminal edges of the sliding panels.

Abstract: An air purifier system includes at least one air purifier and a portable user interface device. The user interface device for positioning at a remote location from the at least one air purifier and wirelessly communicated to a controller of at least one of the air purifiers. The user interface device includes a sensor configured to measure an air quality parameter in an area proximate the user interface device for transmission of the air quality parameter to the controller of the at least one of the air purifiers via wireless communication; and a user interface comprising (a) a display for displaying data including at least air quality data from the sensor and (b) a user input control for the user to change one or more functional parameters of the at least one of the air purifiers via the wireless communication.
