    Hi all,

    We recently got someone to put in a bathroom unit it it was a miserable day so he did all the work in the shed.

    The whole shed (30'x20') is now covered in MDF dust. I'm wary of hoovering it and I'm wondering should I hire an industrial hoover and what mask I'll need to tackle it safely.

    Many thanks

    I'd just vacuum it up. If its a dyson, (or other bagless) give the filter a good shake at the end to stop the dust particles affecting performance. (this should be done every couple of weeks anyway)

    Same with bagged vacuum - brush off the dust particles when finished to stop performance issues.

    If your vacuum doesn't have a HEPA filter it will just suck up the larger visible particles and blow out the finer invisible particles. This won't make the situation worse if you're wearing a decent particulate mask or respirator (FFP2 or FFP3), but it won't solve the problem, and when you vacuum subsequently the particulates will get blown back into the air and resettle.

    I wouldn't be disproportionally concerned about MDF dust. If you don't own a vacuum with very good particulate filters then you're exposing yourself to fine particulates every time you use it. Either use proper masks and open windows when vacuuming or buy a better vacuum.

    Even expensive professional vacuums can be poor with fine particulates. I have a Festool Midi and there was fair bit of controversy on t'internet about it's particulate performance, so I would still mask or use a respirator if I was cutting MDF, ply or hardwood, and preferably do it outdoors. I've been a bit sloppy in the past and regret that.

    Anyway, Which claims to do decent particulate testing and reckon the Numatic Henry Allergy HVA 160-11 (with the HepaFlo bags) has excellent particulate retention, and is fairly cheap, so you could just buy that and then you'd have the advantage of better safety from your regular vacuuming.

    Or just mask up and open windows when vacuuming, and leave the fine dust to settle afterwards.

    This is exactly the type of information I was looking for so thanks a million.

    It's a one-off job so I'll have to hire a hoover with the right filter or see if I can get one for my own hoover.

    I've a mask anyways so that'll hopefully cover me to get it done. Want to clear the dust and get sealant/paint on the floor.

    Thanks again
