5. Frequently asked questions
5.1 What are the core differences between F9 bag filters and F5-F8?
F9 is the highest grade of medium efficiency, with an efficiency of 95-98%, filtering ≥1μm ultrafine dust, suitable for high-end clean scenarios; F5-F8 efficiencies decrease sequentially, suitable for conventional commercial and industrial ventilation, while F9 is specifically designed for high-standard purification scenarios.
5.2 What is the replacement cycle and maintenance method for F9 filters?
In clean environments, filters should be replaced every 3-4 months; in high-cleanliness operating rooms/electronic workshops, checks should be done every 1-2 months; replace immediately when resistance reaches 450Pa; this product cannot be washed and is prohibited from repeated use.
5.3 Can F9 filters replace HEPA filters?
No, it cannot. F9 belongs to medium efficiency filters, with lower filtration precision than high-efficiency filters, serving only as a pre-protection for high-efficiency filters and cannot achieve ultimate purification for 0.3μm particles.
