Project Description

Cardboard Filters are usually for prefiltration in ventilation and air-conditioning units, and in intake air systems and lines, so as to extend the operational lifetimes of the downstream fine filters. The entire filter element contains no metal, and it therefore non-corroding and fully incinerable.
