Environmental characteristics of habitable environments (e.g., hotel or motel rooms, spas, resorts, cruise boat cabins, offices, hospitals and/or homes, apartments or residences) are controlled to eliminate, reduce or ameliorate adverse or harmful aspects and introduce, increase or enhance beneficial aspects in order to improve a wellness or sense of wellbeing provided via the environments. Control of intensity and wavelength distribution of passive and active Illumination addresses various issues, symptoms or syndromes, for instance to maintain a circadian rhythm or cycle, adjust for jet lag or season affective disorder, etc. Air quality and attributes are controlled. Scent(s) may be dispersed. Hypoallergenic items (e.g., bedding, linens) may be used. Water quality is controlled. Noise is reduced and sounds (e.g., masking, music, natural) may be provided. Passive and active pathogen controls are employed. Controls are provided for the occupant and/or facility personnel, as is instruction, and surveys, including assessing wellness.

Systems for coupling the operations of an environmental modifying unit and a smart appliance are described. In one form the system includes a central communication unit, a baby monitor, and a dispenser for modifying the environment in which the baby monitor exists. The central communication unit, the baby monitor, and the dispenser are wirelessly connected to one another.

A system for delivering a volatile composition into the air is provided. The system includes a central communication unit capable of receiving incoming signals and sending outgoing instructions. The central communication unit is communicably connected with a memory configured to store an algorithm. The system includes a smart appliance communicably connectable with the central communication unit and configured to send incoming signals to the central communication unit alerting the central communication unit of a status of the smart appliance. The system also includes a volatile composition dispenser that is communicably connectable with the central communication through a wireless communication link. The algorithm controls the volatile composition dispenser based on incoming signals sent from the smart appliance to the central communication unit.

Environmental characteristics or scenes of habitable environments (e.g., hotel or motel rooms, spas, resorts, cruise boat cabins, offices, hospitals and/or homes, apartments or residences, or other spaces or sub-spaces) are controlled to facilitate certain activities of a user in the environment by increasing focus, preparing for sleep, directing movement, masking ambient noise, and improving air quality, among others. Controllable characteristics include, for example, lighting, CO.sub.2/O.sub.2 levels, humidity levels, sound, aroma, and air temperature. Controls are provided for the occupant and/or facility personnel to select activities or scenes, or sensors detect the activity and implement an appropriate scene.

An airflow treatment device configured to be installed inline in the ductwork of an air handling system (e.g., HVAC system) in a manner that is substantially free of obstructing the airflow through the ductwork or requiring any supplemental power to treat the airflow passing by the treatment device. The disclosed airflow treatment device can also be maintained substantially free of any interruptions, disassembly or downtime to the air handling system after initial inline installation of the disclosed device. In one arrangement, the airflow treatment device is capable of accepting a threaded odor neutralizer container at its base. Ductwork need only be disassembled once to attach the disclosed device inline in the airflow path of the ductwork. When the odor neutralizing agent needs replenished, the container can be detached from the device, replenished, and reattached to the device free of disruption to the air flow of the air handling system.

The present application provides an air purifier comprising a main body, wherein the main body comprises: a housing, wherein an interior of the housing is hollow, an air inlet is formed at one end of the housing, an air outlet is formed at the other end of the housing, and positions of the air inlet and the air outlet are interchangeable; a fan mounted in the housing and used for sucking outside air from one end of the housing or for sucking outside air from the other end of the housing; a photocatalyst member mounted in the housing; and ultraviolet light-emitting members mounted in the housing, so that ultraviolet light emitted by the ultraviolet light-emitting members can effectively irradiate the photocatalyst member.

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.
