A system for decontaminating/neutralizing breathable air and surfaces in an occupied enclosed space, i.e., agricultural greenhouse, includes mounting an atmospheric hydroxyl radical generator along an inside surface of the atmospheric hydroxyl radical generator having respective opposite air inlets and air outlets. The hydroxyl radical generator includes a polygonal housing supporting a plurality of spaced crystal-spliced UV optics, which are tubular, medical grade pure quartz optics to emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating and neutralizing atmospheric chemicals and pathogens in breathable air and surfaces. The hydroxyl radicals contact the walls of the reaction chamber housing. The hydroxyl radicals become created and excited to react quickly with impurities including VOC, virus, bacteria and fungi, rendering them inactivated and neutral. The breathable air passes through the polygonal housing and is decontaminated and neutralized of impurities before entering the occupied enclosed space.

An apparatus includes multiple first reservoirs and multiple second reservoirs joined with a substrate. Selected ones of the multiple first reservoirs include a reducing agent, and first reservoir surfaces of selected ones of the multiple first reservoirs are proximate to a first substrate surface. Selected ones of the multiple second reservoirs include an oxidizing agent, and second reservoir surfaces of selected ones of the multiple second reservoirs are proximate to the first substrate surface.

The invention relates to a household appliance, which comprises at least one catalytically effective substance in a surface, wherein the catalytically effective substance is a polyoxometalate that is comprised in an inner an/or outer surface of the household appliance, provided that the polyoxometalate is comprised at least in an outer surface of the household appliance if the household appliance is a water-bearing household appliance having a container for receiving objects to be cleaned. The invention further relates to a method for operating the household appliance.

The disclosure describes a method for disinfecting an aircraft cabin that includes injecting a non-peroxide disinfectant into an environmental control system of an aircraft and discharging cabin supply air through the environmental control system to discharge the non-peroxide disinfectant into the aircraft cabin. In some instances, the method includes aerosolizing the disinfectant into a plurality of liquid droplets while injecting the disinfectant into the environmental control system. In some instances, the injected disinfectant includes a non-corrosive, non-toxic disinfectant, such that the disinfectant may be discharged into the aircraft cabin in the presence of personnel in the aircraft cabin.

A face mask containing a network of conductive activated carbon meso-fibers crosslinked with a crosslinking agent bonded to a insulative polymeric micro-fiber based purification element. The purification element is captured between two ridged porous elements and contacted to the face by a biocompatible flexible polymeric seal. Optionally the front cover attaches to a main frame of the mask through a system of sliding locks that are coupled with bayonet latch mechanisms. The face mask attaches to the head of a wearer through a harness that couples with the sliding locks or alternatively with a biocompatible adhesive.

Various embodiments are directed to a coronavirus air sanitization/isolation system with anti-virus curtain. The system may include a group of anti-virus strips with attached separation magnets coupled to an air inlet housing mounted above (e.g., in an attic ceiling) in an enclosed space. The anti-virus strips may be coated with a saline and soap solution that attracts airborne droplets contaminated with the coronavirus and dissolves a fatty layer of coronavirus cell membranes to prevent cell replication of the coronavirus, thereby destroying the coronavirus. The air inlet housing may include exhaust ventilation fans, salt filters, a wick saturated with the saline and soap solution, an electro-static air filter, and a distribution air duct. The fans may be utilized to circulate an airstream containing the coronavirus through the anti-virus strips, the filters, the saturated wick, and the distribution air duct to remove the coronavirus while protecting occupants with uncontaminated air.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

An absorbent article comprising a complexed or encapsulated malodor control composition having at least one volatile aldehyde and an acid catalyst, and methods of use thereof, are provided. The malodor control composition is suitable for a variety of absorbent articles, including use in diapers, toddler training pants, adult incontinence garments, sanitary napkins, pantiliners, interlabial devices, hemorrhoid pads, and the like.
