Bathroom Fan ?

Well, insdie the soil pipe is deprecated :-)

For maximum efficiency it should be mounted as high as possible (warm air rises) and opposite the source of air (door, window, whatever) that replaces the air extracted . If placed too close to the source of replacement air then local air circulation can be set up which leaves the rest of the room untouched.

If the above leaves you spoilt for a choice of sites then consider any prevailing wind direction on your house. Pointed 'into wind' will mean the fan spends most of it's time with the anti-draught vanes pushed shut on windy days.

Well somebody pointed out on here once that it makes sense not to position it so that the loo, sink and extractor are all in line, meaning that the s***ty-molecule-laden airflow is sucked from the toilet over the toothbrush rack and out of the vent.

A good reason for putting the toilet seat down before flushing.

Yes

Mythbusters played with this one, keeping serried ranks of toothbrushes in their bathroom for a week. On subsequent microbiological analysis, they could find no contamination of the brushes above background.

Most important is the removal of moisture laden air, so position it close above shower (if you have one). Otherwise the damp will condense on walls rather than being removed. Second most important - get a decent fan not a cheap shed piece of tat. I have installed Vent Axia 125 inline fan for bathroom and Xpelair 100mm fan for downstairs toilet - both work well. I inherited a Manrose 100mm fan in en suite - diabolical!!

If you want to do the job once and be satisfied with the result get quality item.

Dunno who 'mythbusters' are, but I'm delighted to hear it! ;-) David
