  • Patent number: 10918993
    Abstract: The Phipps indoor air filter (PIAF) is configured for use with an indoor atmosphere that contains one or more pathogenic viruses. The PIAF is a pharmacologically and phytochemically (P&P) active structure that removes the one or more viruses from the confined indoor atmosphere. The PIAF removes the one or more viruses by: a) sequestering the one or more viruses within the PIAF; and, b) terminating the biological processes of the one or more viruses using P&P structures. The PIAF incorporates a flow chamber and a filter structure. The flow chamber contains the filter structure. The flow chamber forces or draws an air flow through the filter structure contained within the flow chamber. The filter structure physically and biochemically: a) sequesters the one or more viruses; and, b) terminates the biological processes of the one or more viruses by exposing the one or more viruses to the P&P structures.

  • Patent number: 10874762
    Abstract: An anti-bacterial lighting apparatus includes one translucent housing, at least one light source, and an air circulation mechanism. The translucent housing is air permeable, has as least one air inflow port, and has an anti-bacterial photocatalytic film on its inside surface. The at least one light source is inside the housing, and its light activates the anti-bacterial photocatalytic film on the housing. The air circulation mechanism, such as a fan, is at the air inflow port of the housing. It sucks the ambient air from outside the housing and forces the air through the air-permeable housing. The air-permeable housing traps airborne bacteria and viruses, and the activated anti-bacterial photocatalytic film kills the trapped bacteria and viruses. Moreover, the light shines through the translucent housing while the apparatus is filtering the air and killing the airborne bacteria and viruses.

  • Patent number: 10850001
    Abstract: An air sterilizing apparatus is created which can be set within an environment without adversely affecting people, pets, or plants within the environment such as a room. The apparatus uses a passage through which ambient air passes. The passage has a treatment chamber in which ultraviolet light (ideally UV-C) is used to sterile the ambient air. Each end section of the passage is configured to block light from exiting the passage. In the preferred embodiment, each end section includes a coating of UV adsorbing material to provide further protection to the environment from the UV light.

  • Patent number: 10806818
    Abstract: A method of treating air passing through an air handling unit having a housing extending around an air handling space and a primary air treatment system that treats air as the air passes through the air handling unit between air inlet and outlet locations on the air handling unit. First and second fixtures are obtained, each having a housing and a UV light source. The first and second fixtures are strategically mounted to the air handling unit so that UV light from each of the UV light sources on the first and second fixtures treats air moving through the air handling unit with the UV light sources on the first and second fixtures energized. The first and second fixtures are serially electrically connected to a power source to thereby cause the UV light sources on the first and second fixtures to be energized through the power source.
