Keeping the Bathroom sweet and fresh - even with drying clothes
Extractor doing a great job driving the bathroom air flow - we're using it both as a bathroom and as 'Swedish Cupboard' where clothes dry. Having moved to the 'always on' low powered fan, and the heat recovery, the bathroom is noticably fresher - it could get a bit fuggy in the winter when stuff takes longer to dry.
Not sure the 'boost' mode (linked to the lightswitch) is even necessary - it certainly is noisier in that mode than our previous fan, tho the 'steady state' hum is quite acceptable and isn't heard beyond the bathroom door.
