5. FAQ
5.1 What are the core differences between F9 bag medium filters and F5-F8?
F9 is the highest grade of medium efficiency, with 95-98% efficiency, filtering ≥1μm ultrafine dust, used in high-end clean scenarios; F5-F8 have decreasing efficiency, suitable for conventional commercial and industrial ventilation, while F9 is designed for high-standard purification scenarios.
5.2 What is the replacement cycle and maintenance method for F9 filters?
Replace every 3-4 months in clean environments, check every 1-2 months in high-clean operating rooms/electronic workshops; replace immediately when resistance reaches 450Pa; this product is not washable and cannot be reused.
5.3 Can F9 filters replace HEPA filters?
No. F9 is a medium efficiency filter, with lower filtration precision than HEPA filters. It only serves as pre-protection for HEPA filters and cannot achieve final purification of 0.3μm particles.
