An apparatus and method for inactivation of airborne pathogens to include a reactor space with an intake opening, an exhaust opening, and an airflow path disposed between the intake and exhaust openings for air to continuously transit throughout the reactor space. The apparatus also includes at least one of (i) a corona discharge unit with a pressure swing adsorption unit, or (ii) a UV-C germicidal lamp to generate a sufficient concentration of ozone and UV light to inactive pathogens. The apparatus also includes a catalyst disposed within the path of the airflow to convert ozone to oxygen following the inactivation step and an adsorbent to remove nitrogen oxides from the air. The apparatus also includes sensors for measuring ozone and nitrogen oxides concentrations at the exhaust opening.

A food waste disposer including a housing, a container disposed inside the housing and provided to accommodate food waste, an exhaust duct communicating with the container and provided to allow exhaust gas generated in the container to flow therein, a filter device including a catalytic filter part configured to filter the exhaust gas passed through the exhaust duct, and a deodorizing filter part configured to filter the exhaust gas passed through the catalytic filter part and communicating with an outside of the housing, and a condensation chamber configured to remove moisture in the exhaust gas flowing from the exhaust duct into the catalytic filter part of the filter device.

An assembly for filtering toilet bowl odors including a first housing respectively disposed in spaced relation to and in fluid communication with the toilet bowl. A conduit connects interiors of the first and second housings in fluid communication with one another. A fan assembly is mounted within said first housing in fluid communicating relation with second housing, via the conduit, and is disposed and structured to define a path of fluid flow extending from an inlet of said second housing, through said conduit and a filter assembly, disposed in the first housing and/or second housing, to the exterior of said first housing, concurrent to activation of the fan assembly.

Vertical growing uses a plurality of shelves to support plants. The system has an air filtration and ultraviolet (UV) air purification system. The purified and filtered air is mixed with nitrogen, which is directed towards plants. The system can include lights to help grow the plants placed on the shelves. The filters can remove odors from the circulating air.

A system for environmental maintenance includes a vacuum unit, an air purifier unit, a controller communicatively connected to the vacuum unit and the air purifier unit, a sweep sensor communicatively connected to the controller, and a movement sensor communicatively connected to the controller. The sweep sensor detects debris swept into a detectable vicinity of the sweep sensor and the controller turns on the vacuum unit upon detection by the sweep sensor. The controller turns on the air purifier unit upon the vacuum unit being turned on, and the air purifier unit cycles on for a period as programmed in the controller. The movement sensor detects movement in detectable vicinity of the movement sensor and the controller turns on the air purifier unit upon detection by the sweep sensor, if the air purifier is not already turned on.
