• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

just getting ready to buy a new mask/ or cartridges for the one I have.

which is this one http://www.ebay.co.uk/itm/Gerson-9000E- ... SwH09ZJZsj

has twist on cartages, and disposable prefilters ..

I used to do more painting .. hence having a paint respirator
and have just stuck with it since out of habit

Assuming if it filters out paint/solvent fumes, then MDF dust should be no problem .
You know what ASSUME does ! lol ...

What do people think ?
What would you choose ? what do you use ?

My workshop is constantly full of fine MDF dust .. which is my main concern.
Secondly, I will be using a bit more paint and solvent finishes for the short term .. maybe more if that product line takes off. I've never been impressed with water based dyes and finishes.

Yes .. I know I should be getting rid of dust at source .. , but for now, I wear a mask :oops:
 
I'm no expert on dust masks but I also use them regularly.

The one you linked to is probably fine but I can't see any reference to the sort of grading numbers that are usually on dust masks. P1 P2 and P3 are the rating I'd expect to see.

P3 respirator style is what I wear for spraying as it removes solvent smells. I'd guess as yours is a respirator type it may be P3 rated so will be OK for fine dust too but no mention of P3 that I can see.

A P2 would probably be ok for the dust too. Disposable masks with P2 rating are what I wear when making dust. Think the straps/ elastic colour means something and mine are blue which means P2....I think.
 
Zero experience of mask grades here but I would think that a filter capable of removing smells and vapours would be based on activated charcoal adsorbing organic solvents etc and be absolutely no measure of dust particle filtration performance which needs to be mechanical or in extremis, electrostatic.

A P2 rated mask is generally OK for mdf. Interestingly, as they get progressively clogged, the degree of filtration becomes better until you get to a point where the thing needs to be binned anyway - Rob

yes, I always went on the theory that as they clog, less will get through ... but only up to the point where the filter is saturated and the dust has worked it's way all the way through the filter to the clean side :shock:

I'm currently having a big sort out / move around / clean up , in the workshop. Then I can hopefully get a better handle on the dust problem.

I've been literally paddling in MDF dust for years :oops:
 
I've just purchased a eclipse dust mask it's got p3 replaceable filters, I've only had it about a week, its very comfortable to wear for extended periods and it's very compact

I'd be interested to know how long between filter replacements .

and also the "blow nose" test .. if it's clean when you've been working in thick dust :-)
 
Slightly OT but still relevant. I've recently fitted at Onedia cyclone to the dx system, part of which is a floor 'gulper'. Rather than sweep up and the end of the day (thus creating a cloud of nasty, superfine dust particles) I now use the gulper to vacuum up all the detritus, sawdust and general assorted crap on the 'shop floor at the end of the day. It's difficult to quantify, but I reckon there's quite a distinct reduction in the amount of airborne dust in the 'shop. I still use a P2 mask when routing or doing any hand sanding - Rob
 
yes .. but ! lol .. the dust is about 1" deep .. who knows what useful bits and bobs I have dropped and would like to see again one day ! lol .. Once it's clean , yes, I will do something similar.
For now, if been sieving and using a magnet before I throw anything out !

I did make a cyclone out of an old dyson .. it worked ok, but was much too small to be useful.

My workshop was clean before the CNC ! .. had a full airline blow out the door session every week.
2 desk fans blowing out the door, whilst I (in a mask) chased the dust to the door with an airline.
Since the CNC .. it's been a loosing battle.

The CNC has had extraction added since then, so I think it "should " be manageable again now.

get a detectorist in with a metal detector .
 
What is this 'sweep up at the end of the day' all about ?? :eusa-think: :D
