Great extractor some reviews said it was noisy but I don't think so the only noise is the sound of air being drawn into the vent ? Fitted inlet above shower even after a long hot shower there is not a trace of steam or condensation in the room, before my WC cistern would be dripping water onto the floor & the mirror would be steamed up but now there is none of that & everything is dry ! So much power that there is a draft under the door as air rushes into the room from the hallway to replace the damp air extracted. Wonderful best thing I ever did to remedy the problem.
