Quantitative Cellulose Filter Papers for Accurate Laboratory Filtration and Analysis

The filter element of the air cleaner is divided into two types: dry filter element and wet filter element. The dry filter element material is filter paper or non-woven fabric. In order to increase the air passage area, most of the filter elements are processed with many small folds. When the filter element is slightly fouled, it can be blown with compressed air. When the filter element is seriously fouled, it should be replaced with a new one in time.
