[QUOTE="Geoff1946, post: 489804, member: 28452"] Don't become frustrated. Despite the asides, members here are actually trying to help you! Most bathroom installations have an extractor fan. They are normally 100 millimetre diameter, (4 inch), fans, and usually have a variable run-on time after the lights are turned off. This seems to suit most people and buildings. The cheap/expensive aspect generally affects lifetime rather than performance. Now, as I stated earlier, if everything else is OK but an "ordinary" fan doesn't meet your needs, you really need to look at the performance specifications in terms of "cubic feet per minute", (cfm). BUT, to achieve a significant change you are likely to want the next size up, which is a 150mm (6 inch) and the corresponding larger duct through the wall will be needed. The emphasis on under-door clearance is to ensure that air can get into the room. Only a vacuum pump, (not a fan) can remove air from a room where replacement air can't get in [/QUOTE]
