Techniques for purifier light are provided. A purifier light can determine characteristics of the environment in which the purifier light is installed, determine capabilities of purifier light, determine one or more objectives of the installation of purifier light related to purification of the environment, perform a self-configuration of purifier light according to the determined one or more objectives, and determine and execute suitable actions for purifier light to perform to achieve the determined one or more objectives.

A waste collection unit for collecting waste material. A reservoir is supported on a portable cart for storing a liquid on the portable cart when positioned away from a docking station. A sprinkler may be coupled to the waste container and in fluid communication with the reservoir. The sprinkler is configured to direct the liquid from the reservoir towards the waste container. The reservoir is configured to receive additional liquid from the docking station to urge the liquid from the reservoir towards the sprinkler. A prefill pump may be supported on the portable cart and in fluid communication with the waste container and operable to convey the liquid from the reservoir to the waste container. A controller may be in electronic communication with a valve assembly to control flow of the liquid from the docking station into at least one of the reservoir and a second waste container.

An air purifier including a fan having a plurality of fan speeds; a filter, wherein the fan draws air through the filter; a user interface in communication with a control system; wherein upon activation of the control system, the control system identifies an initial air quality index (AQI) based upon a geographic location of the air purifier, a room size based upon the type of room in which the air purifier is placed, and identifies a fan speed set by a user through the user interface, and determines a target air quality index achievable in thirty minutes of fan operation is provided. Further provided is an air purifier capable of predicting and updating time to achieve a target air quality and a target air quality based on a number of environmental factors.

This invention is a smart face mask for air filtration with a transparent mouth-covering portion, an active air filtration system which filters both air inflow and air outflow, an environmental or biometric sensor, and a smart control mechanism wherein the operation of the active air filtration system is automatically adjusted based on analysis of data from the sensor.

A humidifier/dehumidifier device is disclosed herein. The humidifier and dehumidifier both, respectively, evaporate water from and condense water into a shared (same) water storage container. The device is fitted with an air intake and at least one air outtake. In embodiments of the technology, one or more of the air intakes receives air from outdoors. One or both of an indoor and/or the outdoor intake is used to receive air based on a determination that an indoor and outdoor humidity and temperature is most efficient to achieve a desired indoor humidity or temperature.

The present disclosure relates to air filters. More particularly, it relates to air filters including pleated filter media that can be uniformly expanded and contracted. In some embodiments, the air filters are adjustably sized air filter systems. In some embodiments, the air filters can be used in a window opening.

A work facility that is capable of adjusting an air volume without a work defect and saving energy. The opening degree of an air volume adjusting damper corresponding to a filter booth for which the individual air volume measured by a corresponding individual flowmeter is the smallest among the respective individual air volumes for the filter booths is adjusted to a completely open state, whereas the opening degree of any other air volume adjusting damper is adjusted to such an opening degree that the individual air volume for the corresponding filter booth as measured by a corresponding individual flowmeter is equal to the smallest individual air volume, and a gas discharge fan is adjusted by a total air volume adjusting mechanism so that a total air volume measured by a total flowmeter is equal to a predetermined target total air volume.

A system and method for maintaining, monitoring and improving air quality and purity in a room or environment, such as a hospital room or operating room.

A humidification and air cleaning apparatus is provided that may include a lower base, a lower housing, a plurality of legs, a leg wall, and an input assembly. The lower base may be supported by an installation surface. The lower housing may be spaced apart upwardly from the lower base and form a suction gap by being spaced apart from the lower base. The plurality of legs may be disposed on at least one of the lower base or a lower housing. The plurality of legs may support the lower housing. The leg wall may connect two adjacent legs to each other. The input assembly may be disposed at the lower housing. The input assembly may protrude toward the suction gap. The input assembly may receive a wireless signal. The plurality of legs may include a first leg and a second leg adjacent to each other. The input assembly may be disposed outside of the leg wall. As an input assembly receiving a voice signal is exposed to the outside, a user's voice may be effectively recognized. Further, as the leg wall is disposed between the input assembly and the lower housing inlet, it is possible to suppress propagation of operating noise generated by a blowing unit to the input assembly.
