Pollen filters, are responsible for filtering all air entering the vehicle’s interior, as well as the air being circulated by the air-conditioning system. G.U.D. manufactures a range of pollen filters designed to remove particles such as pollen, dust and soot. In addition G.U.D. offers carbon-activated filters, which remove particles, as well as absorbing outside noxious gases and odours. Pollen filters are available in irregular, rectangular and trapezoidal shapes.
