Described herein is a device, and consumer articles associated therewith, for dispensing an active composition and absorbing malodors in the surrounding space.

The vehicle interior deodorizer may comprise a deodorizing device for deodorizing the interior of a vehicle and a method of using the deodorizing device. During a treatment cycle, the deodorizing device may release a chemical tablet into a cup holding water after an evacuation interval. The chemical tablet may dissolve in the water, creating a deodorizing solution. A bubbler mechanism may de-gas the deodorizing solution and may force deodorizing gas out of the deodorizing device such that the deodorizing gas may saturate the interior of the vehicle during a treatment interval. The bubbler mechanism may quiesce during a dissipation interval such that the deodorizing gas may abate. The vehicle may be opened and aired out to complete the treatment cycle.

A built-in apparatus and method for treating air including a housing with an air inlet and an air outlet. An air mover positioned near the air outlet is configured to draw the air through the air inlet. The housing encloses an air treatment zone, such as including an oxidizing zone, and an ozone removal zone positioned downstream of the air treatment zone and oxidizing zone. The air treatment zone includes UV light and/or ozone that partially oxidizes the chemical contaminants in the air treatment zone. A catalyst in the oxidizing zone oxidizes elements within the air treatment zone. The ozone removal zone includes a second, different catalyst material. A UV bulb that may or may not generate ozone is positioned within or downstream of the first and/or second catalyst materials to assist catalyst oxidation and/or self-clean the apparatus.

A system for treating emissions from a vehicle includes an ozone generator, a first holding tank, and an exhaust vent. The first holding tank is downstream from the ozone generator and defines a volume for liquid waste beneath a void space. The exhaust vent is downstream from the first holding tank and outside of the vehicle. A supply conduit connects the ozone generator to the void space of the first holding tank. An exhaust conduit connects the void space of the first holding tank to the exhaust vent. The ozone generator, supply conduit, void space of the first holding tank, exhaust conduit, and exhaust vent establish a thermal driving head from the ozone generator through the void space of the first holding tank to the exhaust vent.

Articles can be provided with odor resistance by applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier onto the surface of the article and allowing the inert liquid carrier to penetrate into it. The N-halamine accordingly becomes deposited on the surface of the article after the inert liquid carrier penetrates into the article. This method can be used to provide odor resistance to a variety of substrates, including garbage bags. It can also be used to deposit other functional particulates onto the surface of substrates having sufficient porosity to take up the vehicle. For instance, such functional particles can be oxidants that display antimicrobial and/or enzyme inhibitory efficacy or particles having toxin interaction potentials through oxidative degradation or adsorption of toxic substances in air and/or water, such as fluoride uptake by metal oxide microparticles.

An apparatus for cleaning exhaust gas. The apparatus includes a housing having an upstream end configured to receive exhaust gas and a downstream end configured to release the exhaust gas. At least one coalescing filter layer and a catalyst filter layer are disposed within the housing. The catalyst filter layer includes molded sintered pellets formed from a porous material and a non-precious metal catalyst. The molded sintered pellets create a porous area for coalescing oil mist, and the catalyst hydrogen peroxide.

Disclosed are methods and apparatus that help reduce and prevent infection by controlling and/or reducing the level of contaminants, which include pathogens, allergens and/or odor-causing agents including VOCs. Photocatalytic oxidation is performed in a high humidity environment so that hydrogen peroxide molecules are readily produced.

The present disclosure provides an air disinfection apparatus for use with an air conditioning system configured to create an airflow. The air disinfection apparatus comprises a hollow housing for conveying said airflow therethrough between an air inlet and an opposite air outlet determining an airflow direction; a screen forming a non-ionizing electrode extending along a screen longitudinal extension axis, said non-ionizing electrode being mounted in the housing between the air inlet and the air outlet so that a screen surface is tangential to the airflow direction; a wire forming an ionizing electrode, said wire being suspended in said hollow housing between the air inlet and the air outlet and having a wire axis aligned with the screen longitudinal extension axis so as to face said screen surface; terminals electrically connected to the wire and screen for coupling thereto high and low voltage outputs of a high voltage generator of sufficient voltage to create a corona discharge zone across the airflow between the wire and the screen; wherein the screen includes an ion receiver positioned downstream of the corona discharge zone relative to the airflow direction, said ion receiver being dimensioned to cause ions produced in the corona discharge zone to be attracted so as to prevent release of ions outside of the air disinfection apparatus.
