Abstract
In a method and apparatus for cleaning filters, the cleaning is efficiently performed by selecting cleaning steps according to the degree of contamination of the filter media. The degree of contamination of the filter media is analyzed before the filter is carried into the cleaning apparatus. Filters with heavily contaminated filter media are subjected to pretreatment before the cleaning process is performed, and the filters with less contaminated filter media are directly subjected to the cleaning process. The cleaned filter is subjected to a restoration process before reuse.
