Add ULPA for critical zones.\u003C/li>\n\u003Cli>\u003Cstrong>Electronics & Semiconductors:\u003C/strong> G3 pre-filter → F7 medium → H13 HEPA.

Use anti-static filter housings.\u003C/li>\n\u003Cli>\u003Cstrong>Food & Beverage:\u003C/strong> G3 pre-filter → F6 medium → H13 HEPA. Prioritize food-grade certified filters rated for high humidity. Comply with HACCP and local food safety regulations.\u003C/li>\n\u003Cli>\u003Cstrong>Hospitals & MOT:\u003C/strong> G4 pre-filter → F8 medium → H14 HEPA. Ministry of Health standards mandate minimum 99.97% efficiency for operating rooms and ICU.\u003C/li>\n\u003Cli>\u003Cstrong>Laboratories & Research:\u003C/strong> G4 pre-filter → F8 medium → H14 HEPA. Microbiology and biotechnology labs require maximum cross-contamination protection. Consider filters with antimicrobial coating to prevent microbial growth on filter media.

H14 captures ≥99.995% — required for ISO 5-6 and pharmaceutical aseptic areas. The price difference is about 20-30%, but H14 provides 10x better protection against remaining particles.\u003C/p>\n\u003Ch3>How Do I Monitor Filter Cascade Conditions?\u003C/h3>\n\u003Cp>Use differential pressure manometers at each stage.
