F7 Bag Filter
The F7 Bag Filter captures 80-90% of particles in the 0.4–1.0 micron range, protecting cooling coils, fans, and HEPA systems from dust, pollen, smoke, and bacteria. Its multi-pocket design delivers low initial pressure drop and high dust holding capacity, reducing fan energy costs and extending replacement intervals. Available in standard 592×592 mm sizes and custom configurations, this F7 Pocket Filter fits most commercial AHUs without modification. The pink media color confirms F7 grade at a glance, simplifying maintenance. Manufactured by SNYLI under ISO 9001, it is a practical choice for data centers, pharmaceutical packaging areas, airport terminal ventilation and cleanroom pre-filtration.

Product Description
The F7 Bag Filter is a medium-efficiency air filter used in commercial HVAC systems and industrial ventilation. It captures particles (dust, pollen, smoke, bacteria) in the 0.4–1.0 micron range before they reach cooling coils, fans, or downstream HEPA stages. The pink media color is a European convention: F7 grade is always pink, which reduces the chance of installing the wrong class during maintenance.
This filter is not designed for heavy industrial dust loading (cement kilns, steel furnaces). Those applications use pulsejet or reverse-air baghouses with woven fabric bags. An F7 Pocket Filter belongs in clean or lightly contaminated air streams - offices, hospitals, electronics assembly, pharmaceutical packaging areas.

Why Buyers Choose This
Our F7 bag filter has the following advantages:
- Lower energy cost than you expect.
A filter with 80 Pa initial resistance saves measurable fan power every hour of operation. Over a year, that difference often exceeds the filter's purchase price. This is why this EN 779 F7 Filter is often specified instead of others in continuously operating systems.
- Longer replacement intervals.
The multi-pocket design holds more dust before pressure drop becomes excessive. Most users replace this F7 Pocket Filter every 4–6 months in normal environments, not every month.
- Protects expensive equipment downstream.
Cooling coils, fans, and HEPA filters last longer when coarse and medium particles are removed upstream. This Medium Efficiency Filter is the practical barrier between outdoor air and critical indoor equipment.
Where They Are Installed
The F7 bag filter can be applied in various environments.
- Office buildings -- main AHU filtration before cooling coils
- Hospitals -- general ward ventilation, not operating theatres (those need HEPA)
- Electronics assembly -- pre-filtration for cleanroom HEPA systems
- Pharmaceutical packaging -- controlled areas where product exposure is limited
- Airports and shopping malls -- large central AHU banks
For North American projects, the MERV 13 Filter equivalent is often specified instead of F7, these two ratings come from different test standards. A Bag Air Filter is also commonly used as a pre-filter in data center cooling systems.
