A humidifier includes a first housing, a second housing, a water atomization module, an essential oil delivery module, and an essential oil container. The first housing includes an outer wall including a recess. The second housing is fixedly embedded in an upper part of the recess. The water atomization module is disposed in the first housing. The water atomization module includes a first container, a water passage, and an ultrasonic atomizer. The water flows out of the first container, enters the water passage into the ultrasonic atomizer, and is atomized to produce mist. The essential oil delivery module is disposed in the second housing. The essential oil container is connected to the essential oil delivery module. The essential oil delivery module is configured to transfer essential oil from the essential oil container to the water passage so that the essential oil and the water are atomized together.

An environmental control system includes: a wind blower which blows wind toward a subject; and a control apparatus which obtains at least one time included in a scheduled wake-up time of the subject, a scheduled go-to-bed time of the subject, a sunrise time, and a sunset time, and switches control on the wind blower at the at least one time obtained.

Systems and methods to treat an environment. The system includes a plurality of scent control material sources configured to output a scent control material (e.g., an oxidant) into the environment to reduce pathogens, dispose of scent molecules and their sources, and otherwise treat the environment. The system can include a controller communicatively coupled to the plurality of scent control material sources and cause one or more subsets of the plurality of scent control material sources to individually or collectively output scent control material into the environment.

This present invention relates to a unique HVAC air filter holder designed to prevent or reduce air from escaping or otherwise bypassing the HVAC air filter. The HVAC air filter holder comprises a filter securing device, and is a material that is compressible, moldable, expansible or the like such that it can be secured around the perimeter of the air filter.

A method of maintaining a desired level of a dispersed liquid within an occupiable semi-enclosed space is provided. The method includes: providing a liquid diffusion appliance including a liquid to be dispersed; operating the liquid diffusion appliance to disperse the liquid into the occupiable semi-enclosed space throughout a treatment period in which the occupiable space is subjected to entry and exit of occupants to and from the occupiable semi-enclosed space; sensing the concentration of one or more chemical components of the dispersed liquid within the occupiable semi-enclosed space; and modifying the operation of the liquid diffusion appliance based on the concentration of the one or more chemical components of the dispersed liquid within the occupiable semi-enclosed space to achieve a desired concentration.
