    This was being discussed in another post, but I thought it was a worthy topic to have it's own title and start a discussion.

    All woodworkers should know that the dust from all hardwoods and many softwoods, can be carcinogenic. The biggest factor is the sub-micron particles, which the human lung absorbs, but cannot expel. That's why MDF is the worst of all - tiny dust particles. Kidafornia is working on spalted beech which has the added hazard of fungal spores. The characteristic black bit in spalted beech is fungus.
    Hope this helps.

    I have just bought a few FFP3 dust masks, but I have no vacuum system or air filtration system and I work in a confined space (12x12' garage). I would be interested in your thoughts on whether this mask (and goggles) is good enough providing it is replaced often and I keep the garage clean.

    If this is a gas & vapour respirator Like this one
    http://www.conpargroup.co.uk/mask4277.htm
    These are disposable and are widely available and last about 40 hours of use
    There is also one available thats not disposable you can change the filters on them
    The best place to buy them is in a vehicle body shop supplier

    Have to admit I can be neglectful in the shed where masks and such are concerned, don't do so much turning now and use extractors for saws and planers, but I have felt the effects at times after turning and not covering up.

    In an ideal workshop, dust would be extracted at source and we would have air filtration systems as well as powered respirators. Personally, I have a fairly good dust extraction system and fans to pull air outside, but I find wearing masks all day uncomfortable and I dislike the noise of fans running continuously. In the summer, it's fine - I just work with the doors open: but in the winter, I want to retain heat and tend to have the fans on as little as possible. The idea of air cleaning machines like the "Microclene" which filter out dust particles without venting the air (and heat) outside, doesn't appeal to me - more noise and expense and it takes time to clean the air - where is the dust going in the meantime?
    I think that no matter what we do, no dust extraction system is, or will ever be, perfect.
