Investing Air Filter Set for Ductless Fume Extractor Hood

This investment filter set is a safety-critical component designed to trap fine silica dust during the investment mixing process. It includes a Stage 2 HEPA filter that captures 99.97% of dangerous particles as small as 0.3 microns. The bottom woven-fiber layer acts as a pre-filter to catch larger investment debris and extend the life of the HEPA cartridge. Using this filter set prevents the inhalation of hazardous particulates that are common in the casting preparation area. It provides a laboratory-grade solution for maintaining air quality in a busy jewelry manufacturing environment.
