Abstract: A ventilation assembly having a moveable trim moveable between an open position in which the moveable trim defines a gap with a ceiling trim to allow movement of fluid and a closed position in which the moveable trim is against or adjacent to the ceiling trim to eliminate or reduce the gap and prevent or limit fluid flow.

Abstract: An energy-recovery ventilator system is configured to be mounted to a window of a building. The energy-recovery ventilator system includes an energy recovery ventilator configured to exchange air and including an indoor ventilator section arranged to lie on an indoor side of the window, an outdoor ventilator section arranged to lie on an outdoor side of the window, and a ventilator manifold extending between and interconnecting the indoor ventilator section and the outdoor ventilator section.

Abstract: A range hood for a microwave includes a range-hood mount and a pair of hood slides coupled to the range-hood mount. Each hood slide includes portions that are configured to move relative to the range-hood mount between a retracted position and an extended position. The range hood further includes an expandable hood extension coupled to the pair of slides and configured to move from a collapsed configuration, when the pair of slides are arranged in the retracted position, to an expanded configuration, when the pair of slides are in the extended position.

Abstract: A method of controlling ventilation of air within a local environment of a structure includes determining an indoor air quality level based on signals from one or more monitoring devices located in the local environment. In indoor air quality system includes one or more monitoring devices that determine the indoor air quality level and activate one or more appliances based on the readings from the one or more monitoring devices.

Abstract: A air inlet for an air handling unit includes an intake grate that extends around a central axis and is configured to admit an airflow therethrough. The air inlet further includes an outlet duct arranged to lie along the central axis and positioned radially inward of the intake grate. The air inlet further includes a debris collection housing.

Abstract: An air inlet for an air handling unit includes a duct defining a passageway leading to the air handling unit. The fresh air inlet further includes an intake screen that is formed to include a plurality of openings sized to allow airflow to pass through the openings to the air handling unit. Particles are blocked from adhering and accumulating to surfaces of the intake screen.

Abstract: A ventilation system includes a main housing defining an internal region and a blower contained within the internal region. The ventilation system is positioned adjacent to a room of a building structure and is configured to draw air out of the room to provide ventilation. The ventilation system further includes a grille secured relative to the main housing using an attachment feature.

Abstract: A range hood includes a hood canopy configured to collect and exhaust effluents from a cook top and a hood skirt coupled to an outer edge of the hood canopy. The hood skirt has a front surface that faces outwardly away from an interior effluent-collection region defined by the hood canopy and the hood skirt. A removable trim is coupled to the hood skirt.

Abstract: According to an aspect of the present disclosure, an air quality management system may include a mobile application distributed to at least one user device, at least one air quality management device, and at least one computing resource, wherein the at least one computing resource operates a first networking layer configured to receive input from the at least one mobile application. Also, the at least one computing resource operates a second networking layer that receives input from the at least one air quality management device. The air quality management system may further comprise a data connection between the first and second networking layers to transfer commands of the at least one mobile application from the first networking layer to the second networking layer, and to transfer device information of the at least one air quality management device from the second networking layer to the first networking layer.
