F7 Pocket Air Filter: Factory-Direct Prices
Why Choose Factory-Direct F7 Bag Filters?
- Lower Costs for You: By cutting out distributors, we pass 15%-30% savings directly to our customers. Whether you need 10 units for a small HVAC upgrade or 500+ for a factory-wide project, our bulk factory pricing ensures you get the best value.
- Faster Lead Times: No waiting for third-party stock-our workshop keeps standard F7 sizes (592x592x600mm, 495x495x500mm) in production year-round. Standard orders ship within 3-5 days; custom frames (galvanized steel, aluminum, stainless steel) or media (high-temp, anti-microbial) take just 7-10 days.
- Full Quality Control: We oversee every step from raw material to finished product-no outsourcing, no compromises. Every F7 filter is tested for pressure drop, filtration efficiency (80%-95% for 1.0-3.0μm particles), and seam strength before leaving our factory.


As a factory-direct supplier, we don't just sell filters-we support your project from start to finish:
- Free Technical Consultation: Our product specialists can help you calculate the right number of F7 filters for your HVAC system or paint booth, recommend custom options , and even provide installation guides.
- Sample Orders Available: Not sure if our F7 pocket air filter fits your system? You can request a sample to test efficiency, size, and compatibility before placing a bulk order.
- Long-Term Partnerships: We work with HVAC contractors, industrial facilities, and commercial builders-offering exclusive factory pricing for repeat customers and priority production for urgent projects.
FAQ
Q1: What is the difference between F7 and F8 bag filters?
A1: F7 filters (80%-95% efficiency for 1.0-3.0μm particles) are medium-efficiency, ideal for pre-filtration of HEPA filters or general HVAC needs. F8 filters (90%-95% efficiency for 0.5-1.0μm particles) have higher efficiency, suitable for stricter environments (e.g., pharmaceutical cleanrooms).
Q2: Can the F7 bag filter be washed and reused?
A2: No. The synthetic media is designed for single use-washing will damage the media structure and reduce filtration efficiency. We recommend replacing filters when pressure drop reaches the specified threshold.
Q3: Is the F7 filter compatible with high-humidity environments?
A3: Standard F7 filters work well in ≤80% RH (non-condensing) environments. For high-humidity scenarios (e.g., textile factories), we offer water-resistant media options to prevent media degradation.
