Indesit Tumble Dryer Fluff Filter If your Indesit Tumble Dryer isn’t removing lint and fluff from your clothes correctly, there may be a problem with the fluff filter. Tumble dryers work by forcing hot air through a rotating drum to extract moisture from your clothing. As the clothes tumble inside the drum they rub against each other, breaking off bits of fibre that collect as lint. A damaged or worn Fluff Filter will trap the gathered loose fabric and choke the exhaust of the tumble dryer and a big lint build-up on the filter impedes air flow, slows drying time and increases the dryer’s energy consumption. The Fluff & Lint Filter in your tumble dryer can become damaged or faulty, from excessive clogging or physical damage from foreign objects. Use this genuine replacement filter to increase the energy efficiency of your machine, and avoid fire hazards associated with the build up of fluff. Please check the model fit list to ensure that this part is correct for your model.
