Anti-pollen and insect filter 250 mm. for air inlets in Indoor cultivation. Galvanized steel housing and replaceable G4 mesh that blocks pollen, insects, and dust; mounting with airtight clamps in 250 mm ducts and quick access via lever locks.

The Anti-pollen and insect filter 250 mm. is designed as a physical barrier in air intake ducts of grow tents and rooms, ensuring that the airflow enters free of particles that compromise the microclimate.
The galvanized steel metal box houses a flat non-woven fabric filter with G4 filtration class, stretched over a steel wire frame to maintain stability even with high airflow. Connection to ducts is made using connection clamps with rubber gasket, achieving a hermetic connection that reduces leaks and turbulence.
This solution acts as a G4 pre-filter, protecting intake fans, ducts, and lights from dust buildup and preventing the entry of male plant pollen, fungus gnats, or thrips that may come from nearby gardens.
Maintenance is quick thanks to the lever locks, which allow replacements in minutes to maintain performance and airflow. Direct integration into standard 250 mm lines in cheap indoor grow tents, technical rooms, and drying rooms.
