G3 filter fabric is a coarse-grade mechanical filter media designed to capture larger airborne particles — dust, fibres, insects and coarse solid contaminants. It is used as a pre-filter in air handling units, heat recovery ventilation systems, range hoods and industrial filtration equipment. The fabric is sold by the piece, where 1 piece equals 1 m² of filter area.
Key filter parameters
Filter class
G3 (Coarse filtration)
Fabric height
800 mm (80 cm)
Length per piece
1,200 mm (1.2 m)
Area per piece
≈ 1 m² filter area
How to order
Each piece measures 80 × 120 cm, which equals 1 m² of filter area. Simply order as many pieces as square metres of filter material you need.
1 piece (1 pc) =
1 m²
80 cm height × 120 cm length
Example order
3 pcs = 3 m²
Three strips of 80 × 120 cm
Features and benefits
- G3 filter class — captures coarse dust, fibres, pollen and larger solid particles (> 10 µm)
- Easy to install — fabric is flexible, easy to cut and fit into standard filter frames
- Versatile application — suitable for HVAC, air conditioning, industrial filtration and range hoods
- Pre-filter function — extends the service life of finer filters (F7, F9) placed downstream
