Abstract: A system and method for controlling air quality within an indoor space are disclosed. An example system includes an air circulation unit that moves air through ductwork of a heating, ventilation, and air conditioning (HVAC) system and an air sanitization unit within the ductwork of the HVAC system that sanitizes air passing through the ductwork of the HVAC system. The system further includes an indoor air quality controller that controls a rate at which the air circulation unit moves the air through the ductwork of the HVAC system responsive to inputs received at the indoor air quality controller and controls an operational status of the air sanitization unit responsive to the inputs received at the indoor air quality controller.

Abstract: A combustion-powered fastener-driving tool that include a chamber member retainer assembly configured to enable the controller of the tool to prevent the chamber member of the tool from moving to an open unsealed position and to ensure the tool's combustion chamber remains sealed until the piston fully returns to its pre-firing position.

Abstract: An appliance employing a coolant system that includes a compressor having a housing, a cooling capacity, and operably connected to typically two evaporators for regulating a temperature of the first compartment and a temperature of the second compartment; a shared coolant fluid connection system; a coolant fluid spaced within the shared coolant fluid connection system; and a switching mechanism operably connected to a first fluid conduit that provides shared coolant fluid to the compressor at a first pressure level and a second fluid conduit that provides shared coolant fluid to the compressor at a second pressure level where the second pressure level is less than the first pressure level wherein the switching mechanism is capable of regulating and switching shared coolant flow to the compressor from the first fluid conduit and the second fluid conduit.

Abstract: An air treatment assembly for treating air passing through an air duct comprises a frame defining an interior space and having an inlet opening providing access to the interior space, an air treatment medium sized to be inserted into the interior space through the inlet opening, and a keyed connection between the frame and the air treatment medium to control the engagement of the air treatment medium with the frame. The air treatment assembly also comprises a frame defining an interior space, an air treatment medium sized to be received within the interior space, and an air quality module integrated with the frame.

Abstract: A portable air cleaner having a vertical orientation with a small footprint that uses an electrostatic precipitator to remove small particles from the air in combination with forced air for increased air flow and improved particle removal.

Abstract: A portable dehumidifier comprising a crossflow fan supported in a chassis for rotation about a vertical axis. The compressor and heat exchanger are oriented vertically. The vertically-oriented configuration enables the size of the heat exchanger and fan to be increased to increase the dehumidifying rate without the need for an increase in the footprint.

Abstract: A smaller configuration air treatment appliance that can perform multiple air treatment functions and which has a modular design that enables the manufacturer to reduce the cost of the appliance.

Abstract: The invention relates to an air cleaner and an expandable frame for use with a conventional household air conditioning system with a return duct having an opening sized to receive a standard panel filter. The expandable air cleaner frame comprises a peripheral frame sized to be received within the opening in the return duct and a carrier coupled to the peripheral frame. The carrier supports an air conditioning element, such as a field charger or an electrostatic precipitator. The expandable air cleaner frame is movable between a collapsed position, wherein the effective thickness thereof is less than the opening, and an expanded position, wherein the effective thickness thereof is greater than the opening.

Abstract: An air cleaner assembly for use with a conventional household air conditioning system with a duct having an opening sized to receive a standard panel filter comprises a peripheral frame sized to be received within the opening in the return duct and sized to receive a standard panel filter. The air cleaner assembly is adapted to move a filter element inserted into the recess to a position exterior of the recess so that multiple filter elements can be mounted inside the duct.

Abstract: The present invention relates to a floor standing treatment device that has a front panel and a mainframe assembly adapted to be removably attachable to the front panel. The mainframe assembly has an integrally molded latching mechanism having a latch and one or more L shaped guides configured to cooperate with one or more pairs stops for limiting lateral movement of the latch. The latch is adapted to engage a portion of the front panel for securely attaching the front panel to the mainframe assembly. The air purifier may also have a cavity positioned along a bottom edge of a back housing to house an electrical cord provided with the air purifier. Additionally, the air purifier may also have an elongated slot positioned at the apex of the mainframe assembly for allowing one or two handed carrying of the air purifier.
