In praise of the powered respirator
Last night I sanded the joint compound in some gyproc that I had put up in my workshop. I used an orbital sander and it was almost a white out in the room there was so much dust in the air.
Thanks to the respirator, I didn't breathe any of it. If I'd just used a paper mask, I'd probably still be coughing
So IMO the respirator payed for itself in just this one job.
One question though, apart from eyeballing them, how do you tell when the filter cartridges need replacing?
Cheers
Craig

Craig,
There’s a technical answer and a normal answer - I'll spare you the technical bs.
Firstly it comes down to eye balling it to see if it is caked. The second consideration is decline in volume being supplied through the filter on a good set of batteries. If you perceive an increase in breathing resistance then replace the filters.
I haven't had a good look at the triton respirator but if it takes one of the common particulate P1 or P2 filters then you should be able to get a pre-filter attachment. These filters are cheaper and extend the life of your main cartridges.
On another note never ever back flush a filter (i.e. with a vacuum cleaner or compressed air). It will ruin the structure of the filter and render it useless.
Hope this helps,
Mark

When you go blue, or your eye ball drops out, its time to change the filter...
