The Miele SFAA50 is an Active AirClean Filter with TimeStrip for your Miele vacuum cleaner. This filter helps to filter unpleasant odours, and includes active charcoal which is ideal for households with pets or smokers. This Miele filter is equipped with a TimeStrip which is an innovative filter replacement reminder to help you keep a check on your filter and ensure that it is functioning at its best. This reminder is attached directly to the filter and is activated when the filter is placed in the appliance by pressing firmly on the arrow. When the bar is completely red, the filter is saturated and must be replaced. The AirClean filter system consists of the original Miele dustbag, the motor protection filter and the original Miele exhaust filters to guarantee maximum hygiene. This filter will significantly reduce the amount of fine dust in the room air by 99.9%.
