I have never used a trend, but have seen them around in wood shops. Oddly enough Trend's only certifications are as a face shield impact tested. Their manual states they are not certified in any way as respirators. I do like using disposable respirators, 3M 8233 N100 Particulate Respirator, which are not the same as the party hat dust masks. But a box of 40 of those cost as much as a Trend which has no NIOSH certification.

That's some interesting info that myself and I'm sure a few others were not aware of.

Well, that wont do!
For a company that isn't in the business of making certifiable "respirators", they sure talk up their $400 pressurized face masks in a rather suggestive manner. :grumpy:
Thanks again for the info.
ETA: Sorry if this is seen as thread jacking, but I didn't think I needed to start a new one for this.
This seems kind of interesting.

I wonder what I would need to add to this to make it work?

Five days now, tired but not coughing any more. Hope this is it with this, it really sucked. Did a little work in the shop this morning. Two hours and I was worn out, that's a little disturbing. Doctor said it would take a month to get back. Did I mention that I cleaned my respirator before I used it. This may become obsessive. No you did not hi-jack the thread at this point its just me rambling along. Now go out and clean that thing.
There are certified powered respirators out there. Start by googling "PAPR respirator". Some are just half masks with an added fan, some are full-on hoods or helmets with the fan and respirator cartridges mounted on a belt. All will use some permutation of a standard respirator cartridge to filter the air. None of them will be cheap in price but all will be less expensive than an overnight stay in a hospital. There's also the option of "supplied air" which relies on an air compressor stationed somewhere where the air is clean, and a long hose running to the worker.

an oilless diaphragm type compressor
The oil mist can kill you if you use a normal piston type
Yes supplied air is quite a bit more complicated than just hooking up a mask to the shop air. To do it right there's a special air compressor to be bought, intake filters, another filter between the compressor and the mask/hood, special mask or hood, special dedicated air hoses (leftover oil on the inside of a used hose...not good) and the system needs to be designed to deliver cool air at the proper pressure. Besides the oil mist issue from a piston air compressor, compressing air makes it really hot, and the output pressure from "just any old" air compressor is more than enough to do nasty things like blow out eardrums and cause air embolism. I have seen a rig that was designed to run off shop air with special filtration, regulation, and cooling, but most supplied air systems come with everything from the compressor to the mask/hood. There are a lot of things that can go very badly wrong if you don't get a system that is properly designed and certified as a supplied air respirator...not something to "jerry-rig" on your own.
