Abstract: A laundry dryer is provided with an air recirculation channel which recirculates air from an air exhaust channel to an air supply channel. The air recirculation channel comprises a recirculation air filter which removes debris from the recirculated air before it is redirected to the air supply channel. The recirculation air filter is removably accessible behind an access door at a peripheral region of an access passage to the drying chamber such that it may be easily serviced by a user of the laundry dryer. In some embodiments, the air recirculation channel may comprise a nozzle with an outlet which is concentrically arranged at an inlet of the air supply channel. In these embodiments, the nozzle may direct the recirculated air to the air supply channel such that it is enveloped by fresh air entering from within a cabinet of the laundry dryer.
