Abstract: A reservoir system for an operating unit, such as a humidifier, includes a removable water tank configured to provide the operating unit with water. The removable water tank includes a primary reservoir for holding water, with an opening in the removable water tank fluidically connecting the primary reservoir with a secondary reservoir in the operating unit. A plunger is slidably disposed in the opening and movable between an open position in which the opening fluidically connects the primary reservoir to the secondary reservoir, and a closed position that seals the opening to fluidically disconnect the primary reservoir from the secondary reservoir. A float member in the secondary reservoir includes a buoyant main body and is configured to generate a force upon the plunger to urge the plunger into the open position according to the height of water in the secondary reservoir.

Abstract: A pest trap, such as for flies, includes a disposable bag with a lure therein, and a sealing mechanism set at or near the top of the bag. The sealing mechanism engages with a removable top, which covers a canister. The bag with sealing mechanism is connected to the top, and then the top is placed on the canister, with the disposable bag in the canister. Once the bag has become filled with pest insects, the sealing mechanism is activated, which seals the top of the bag and separates the bag from the top. The top can then be removed from the canister, and the canister upended to dump the disposable bag into the garbage.

Abstract: An air purifying device is provided for removing airborne particles. The device includes a housing including an air inlet and an air outlet. A fan is positioned within the housing for drawing air into the housing through the air inlet and expelling air through the air outlet. A filter assembly is positioned within the housing between the air inlet and the fan. The filter assembly includes a frame and a filter element mounted to the frame. The device has a removable coupler having first and second hangers. A first elongate hanger support is coupled to the housing and removably extends within the first hanger and a second elongate hanger support is coupled to the frame and removably extends within the second hanger.
