The lightweight PRO-ECO VF activated carbon filter is ideal for neutralizing unwanted odors in greenhouses and other rooms. It contains high-quality activated carbon in granular form with a wall thickness of up to 4 cm, which improves the filtering effect. The aerodynamic base ensures efficient penetration of the carbon layer and extends the life of the filter. A high-quality external pre-filter prevents the penetration of particles and increases the life of the carbon layer.
