If you had read that thread properly you would have noticed that it was about the long term effects of formaldehyde emmission, not the carcinogenic properties of wood dust which is well documented.
No one knows if the formaldehyde emmissions from MDF will be a problem in the future as it can off gas for years.

Keith,
Keith, the formaldehyde gas emission information was new to me (so that was very interesting - thanks) I have to admit to having given up using MDF a while ago, for a number of reasons. A) Firstly, like you said, it's long term effects are not known. This worries me - but as with all products, until you have a good statistical batch of people to analyse (e.g. lots of people exposed over a long time) we won't have a good idea of it's medical effect. Either way, I'm not taking the chance, nor will I be one of the statistical "batch"!
B) I never really like working with it. It's no fun to cut, to plane, etc. C) I'd like my projects to me around in 200 years - and I don't think it is known if it will suffer effects of heat, moisture, glue degradation which might spoil your nice "antique" chair that great-great-great grandad Adam made. (No folks, you can't read anything into the last statement :shock: )
Adam (who has his extractor vented out of his workshop so any fine dust, which slips through the filters, doesn't get circulated back into the workshop. (esp MDF dust).
