Anti-pollen and insect filter 315 mm. designed for air inlets in Indoor cultivation. Metal housing made of galvanized steel with replaceable G4 mesh; blocks pollen, insects, and fine dust. Airtight connection to 315 mm ducts using clamps with gasket and lever locks.

The 315 mm Anti-pollen and Insect Filter acts as a physical barrier in air intake vents of grow tents and rooms, keeping the airflow free from particles that alter the microclimate. The galvanized steel box houses a G4 flat filter made of non-woven fabric, attached to a steel wire frame that keeps the mesh taut even with high airflow. The airtight connection with clamps and rubber gasket minimizes leaks and turbulence.
This pre-filter reduces the entry of pollen from male plants capable of traveling long distances, limits access of fungus gnats and thrips, and decreases dust buildup on fans, ducts, and lights.
Maintenance is easy thanks to the lever locks, which allow the mesh to be removed and replaced in minutes. It fits perfectly in 315 mm lines used in technical rooms and in cheap indoor grow tents, forming part of the set of cannabis cultivation accessories aimed at maintaining stable environments during rooting, growth, flowering, and drying. For odor control, it is recommended to combine with a carbon filter on extraction.
All this makes this component a key ally within the catalog of a Grow Shop in Spain.
