    摘要： A decontamination method is a decontamination method for decontaminating the inside of a decontamination target by removing at least one of microorganisms and viruses present in the decontamination target. This decontamination method includes a step of releasing vapor containing peracetic acid into the decontamination target, without releasing mist containing peracetic acid. An average humidity inside the decontamination target during decontamination is RH82% or more. A peracetic acid vapor load that is a value obtained by adding a concentration of peracetic acid in the vapor every minute from a start of decontamination to a completion of decontamination is 2000 ppm or more.

    摘要： 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.

    摘要： A decontamination device according to an aspect of the present invention is configured to decontaminate an air filter for particle removal. This decontamination device is configured to release gas containing peracetic acid such that the gas reaches the air filter and not release mist containing peracetic acid. A system according to another aspect of the present invention includes a container and a decontamination device. The container is configured to hold an air filter for particle removal. The decontamination device is configured to release gas containing peracetic acid into the container such that the gas reaches the air filter and not release mist containing peracetic acid.
