In certain exemplary embodiments, an air purifier comprises a housing defining an enclosure and having an air entrance and an air exit; a particulate filter; a NCCO filter material configured to adsorb and decompose at least one gaseous pollutant; an AOG configured to generate at least one oxidant; an oxidant remover configured to remove at least one oxidant; a fan unit configured to generate airflow from the air entrance to the air exit; wherein the particulate filter, the NCCO filter material, the AOG, the oxidant remover and the fan unit are positioned within the enclosure such that during operation, a flow of air passes from the air entrance to the air exit through the particulate filter and the NCCO filter material along a direction of the flow of air. In certain embodiments, the air purifier may ensure safety to users while efficiency in removing contaminants can be greatly improved.

A filter covering for a sterile container lid, for completely covering at least one gas exchange portion, which is provided on a lid component of the sterile container lid, on an outside of the sterile container lid, the filter covering having at least two clip portions arranged opposite to each other on the filter covering, which are adapted to engage in a form-fitting manner in at least two clip receiving portions provided on the lid component, and by which the filter covering is mountable to and dismountable from the lid component without tools.

A filter unit for a mixing apparatus includes a hydrophilic filter and a hydrophobic vent filter. The hydrophilic filter is configured to receive a fluid including a liquid and gas. The hydrophilic filter is further configured to sterilize the liquid. The hydrophobic vent filter is configured to receive the gas from the hydrophilic filter. The hydrophobic vent filter further includes a vent and a membrane configured to separate an interior of the filter unit from an exterior of the filter unit, the gas being vented from the filter unit by flowing across the membrane and out of the vent. In some embodiments, the filter unit further includes a defoaming device configured to receive gas, foam comprised the liquid containing trapped gas, and some of the liquid from the hydrophilic filter and is further configured to release at least some of the gas from the foam.

A decontamination apparatus is configured to perform decontamination for at least one of microorganisms and viruses present inside an object to be decontaminated. A particle removal filter is attached to the inside of the object to be decontaminated. The decontamination apparatus is equipped with a vapor generator unit and a pump. The vapor generator unit is configured to generate vapor containing peracetic acid without heating and without releasing mist. The pump is configured to suck the vapor from the exhaust side of the particle removal filter and to supply the vapor to the air supplying side of the particle removal filter. This decontamination apparatus is used in a state where the decontamination apparatus is disposed outside the object to be decontaminated.

A sterilizing device includes a housing having an opening in at least one direction thereof. The housing also has a hollow portion configured to allow insertion of an object (target) including part of a human body from the opening into the hollow portion. The sterilizing device also includes at least one air blower unit configured to send a flow of air toward an interior of the hollow portion, and at least one ultraviolet light emitting unit configured to emit ultraviolet light toward the interior of the hollow portion. The ultraviolet light emitted from each ultraviolet light emitting unit includes at least part of ultraviolet light having a wavelength between 190 nm and 230 nm and at least part of ultraviolet light having a wavelength between 230 nm and 237 nm, but does not include ultraviolet light having a wavelength below 190 nm and beyond 237 nm.
