Hydro Breeze Fan

[Biccylova]

i have one of these fans in my bedroom but have been a bit uneasy about it since i heard they can cause legionnaires disease, is this true not just that but can't they encourage mould and mildew to spread.

Don't have experience of them but unless you are not using fresh water and cleaning it I'd doubt there's much chance or they'd have been sued to high heaven by now, surely ? Not that I'm 100% in favour of keeping a room damp though. Doesn't sound wise to use it too often to me.

B0LL0X!

There was a scare story in the US about an outbreak of Legionnaires' Disease that appeared to have been due to the use of an 'evaporative cooler' (similar to the fan you refer to). However it was later traced to a nearby cooling tower.

A study by Puckorius, Thomas and Augspurger, entitled 'Why Evaporative Coolers Have Not Caused Legionnaires’ Disease', which appeared in the journal of the American Society of Heating, Refrigerating and Air-Conditioning Engineers in January 1995 should have put paid to the unfounded rumours that there's a health risk to using evaporative cooling devices but, clearly, it's failed to do so!

Mark Reddick, of the Sleepdvisor website, has suggested some reason why sleeping with a fan on might not be a good idea. (His advice was picked up by the national press and appeared in The Sun, The Mirror, The Metro and elsewhere). However even he doesn't mention Legionnaires' Disease (probably for the very good reason that there's no link whatsoever):

Thank you, that all sounds very reasonable, and since i do keep it clean i shall worry no more. I tend to get very congested in hot weather and this fan does help me breath better.

The problem that I have with this sort of "air cooling" is that it increases the humidity in the room....and in this country hotter weather means higher humidity levels anyway. Ideally, to feel comfortable, you need to reduce both temperature and humidity....which is what a proper "air conditioner" does.
One of the best purchases I made (over ten years ago) was a mobile air conditioner unit...it's still performing brilliantly (although, of course, it's only used relatively infrequently).
