1. A correcting system comprising:
an acquisition unit configured to acquire information indicating a first capture efficiency of a filter for first microscopic particles in an atmosphere around the filter in a usage environment where the filter is installed;
a control device including a processor;
a blowing unit electrically connected to the control device and configured to blow air to the filter in accordance with a command signal received from the control device; and
a storage unit configured to store correction data for correcting the first capture efficiency to a second capture efficiency of the filter for second microscopic particles, the second microscopic particles being microscopic particles defined in a standard that sets reference values for use of the filter,
the control device being configured to
correct the first capture efficiency acquired by the acquisition unit to the second capture efficiency based on the correction data,
perform a determination process to determine whether or not the second capture efficiency obtained by correcting the first capture efficiency is smaller than a predetermined threshold value, and
control the blowing unit based on a result of the determination process such that the blowing unit increases a volume of the air blown to the filter upon determining that the second capture efficiency is smaller than the predetermined threshold value.
