Green Cotton Air Filters have probably the largest range of cone filters available and produce a style and size to suit most appliances. All cone filters are produced to Green Filter's usual high standards and incorporate the pleated design which increases the surface area by up to 10 - 20% thus optimising horsepower, throttle response and torque. All cone filters have a massive filtration capacity and will catch and hold large amounts of dust, dirt and moisture without restricting the airflow.
