How Much Prefilter Media Should I Use

The amount and frequency of prefilter media depend on factors such as the needs of the project, the level of air pollution, and the specification and density of the filter media. Let's take a closer look at the following：

Gram Weight and Specification of Prefilter Media

Prefilter media typically has a grammage weight of 180-400g/m³ and a dust holding capacity of 400-600g/m³, and is suitable for handling airborne contaminants with coarse particles larger than 5 microns, such as dust and foreign matter.

Common specifications include widths of 1250mm or 1400mm, thicknesses ranging from 5mm to 30mm, and lengths of 20m or longer. Depending on the specific needs, you can choose different densities and sizes of primary filter wool.
