A photocatalytic filter includes a filter substrate, the filter substrate being a porous metal, and a photocatalyst fixed to the filter substrate. When a thickness of the porous metal is t (mm) and an average cell number per inch of the porous metal is C (ppi), a product (t×C) of the thickness t and the average cell number C is from 100 or more to 400 or less.

Systems and methods in accordance with embodiments of the invention can operate to decontaminate an environment or surface. In a number of embodiments, an environment or surface is decontaminated by simultaneously exposing it to a combination of peracetic acid vapour and UV-C light. In some embodiments, peracetic acid is aerosolized, then vaporized, and then delivered to a target environment or surface in combination with UV-C to thereby disinfect the target. In various embodiments, the paracetic acid is aerosolized using either a mesh nebulizer or a pneumatic nebulizer.

A continuous flow sterilization system includes an inclined treatment chamber having a first end and a second end. An ozone generator generates a flow gas containing ozone; an input opening to receive a bulk material into the treatment chamber. An input port is provided for introducing the flow gas containing of ozone into the treatment chamber. A first sensor measures a level of ozone in the gas output of the treatment chamber. The other sensors measure ozone concentration and temperature within the treatment chamber. An output opening provides an exit for the bulk material. An output port provides an exit for the flow gas. An auger is disposed within the treatment chamber to move the bulk material through the treatment chamber.

A respirator (100) includes a face mask (130), a porous filter (230) comprising a filtration material, an air flow system (120) in fluid communication with the porous filter (230) and the face mask (130), and an oxidant generator (850) configured to produce at least one oxidant. The air flow system (120) includes an enclosed container (121) and a blower (310) housed within the enclosed container (121). The air flow system (120) is configured to generate a flow of air such that ambient air passes through the porous filter (230) to the face mask (130). At least one contaminant in the flow of air is adsorbed by the porous filter (230), and the filtration material catalyzes an oxidation reaction between the oxidant and the contaminant to promote decomposition of the contaminant on the porous filter (230). According to another aspect, provided is an air purification system including at least one respirator (100) and a decontamination device (800).

Sanitizing an agricultural facility by placing a chamber having an open interior within the agricultural facility. An item is placed within an open interior of the chamber and a door is interlocked. Then light having a spectral content within a narrow range of wavelengths is provided from at least one lighting device toward the item for a predetermined amount of time to inactivate a microorganism. Simultaneously, ozone may be discharged into the open interior to sanitize the item. Before the door unlocks the ozone within the interior of the chamber is directed to a filter for forming oxygen. Sanitizing the agricultural facility by detect humans, and in response, providing a first light with one spectral content when the human is detected, and providing a second light with a different spectral content within a narrow range of wavelengths to inhibit bacteria growth when humans are not detected.

An apparatus for removing excess of a sterilization agent from a web of carton-based packaging material is presented. The web comprises a number of consecutively arranged sections arranged to be formed into packages, wherein each section of the web comprises an opening device attached thereto, wherein at least a subset of the sections comprises a positioning element. The apparatus comprises a positioning element reader arranged to determine a position of the positioning element comprised in or on the web, a control unit configured to estimate a position of the opening device based on the position of the positioning element, and an air pulse device arranged to provide an air pulse, wherein the control unit is further configured to adjust the air pulse device based on the position of the opening device, and the air pulse is provided onto an opening device area of the web such that sterilization agent is removed from the opening device.

There is provided an isolator that is capable of improving work efficiency by shortening a sterilization time, and that is capable of securing a sterility assurance level. An isolator, in which a circulation fan above a work room supplies clean air to the work room via a HEPA filter, includes: the work room; a front door provided in a front surface of the work room; a glove provided in the front door; and an air supply unit that causes an air supply HEPA filter to clean air taken in from an air supply airtight damper, and that causes an air supply fan to supply the clean air into the isolator, when work is performed. When a sterilization gas is removed, the air supply unit is configured such that the air supply fan circulates the air inside the isolator through a sterilization gas-removing catalyst.
