Great Mask for Respiratory Protection

How well can you breathe aerobically in them? Visibility impairment? Cost?

Chipping dead wood, dealing with london planetree in leaf, stump grinding, I wear a cartridge respirator from Home Depot. I can breathe well. Its a bit bulky, but not heavy.
 
Thanks for the link, Steve. Need something for running the alpine magnum, rich exhaust make I sick. :sick:
 
Now I got mine free as a promo. I got a large and have now ordered a xl as it was a little small. No impairment for vision or eye-to. Breathing was pretty easy. They have a non carbon filter that has better breathability. The difference is it doesn't filter out the odors or hydrocarbons. It is still exceptional for the dust. It's a less expensive filter as well. Supposed to breathe easier in the non carbon filter. I think it's comfortable and not cumbersome at all.
 
Not sure about this brand but I'd suggest that you want to make sure that any respirator you use has enough filter capacity for whatever you're trying to filter out too. In respiratory protection there's the concept of break-through for organic vapours or for things like vehicle exhaust gasses (they're not really fumes which is reserved for welding type particulates). Also as you work harder you breath more; more air, more guck, less time until breakthrough or until the filter (if for particulate like dust) is plugged off and the mask or cartridge should be tossed.

There's also the concept of face fit testing and the respirator fit to think about (pinch that wire nose piece!).
Wood dusts are often allergenic but it can also depend upon particle size - fine carbide blade for example - more dust/ dry wood - like pine bettle wood - more dust. Going way out on a limb here, you could say too that the harder the wood the more allergenic potential there is (oak, ash and some of the African woods like bubinga). And then you get into woods we cut as arborists - infected with fungus or mould and spores or just plain old sick trees which can increase the amounts of terpenes, aldehydes, etc. in the wood as the tree tries to defend itself against infection.
This would perhaps make an interesting literature review for one of the arborist journals sometime?
For example: https://www.ncbi.nlm.nih.gov/pubmed/8231799
https://www.ncbi.nlm.nih.gov/pubmed/11426929
 
The micron readings seem to be well within the size and nature of most common molds and allergens I could find on the inter webs. Seems like this is a good product. As so far as the fit testing, there is a lot to that as we have to do annual fit testing in the fire department. This is an affordable much better than nothing solution for the working man like me who isn't going to take the time to seek out mask fit testing and all the screenings that go with it. There is information on their site about usage time and disposal time frames.

Ive started using this on nasty dead oaks as they always give me a sinus infection. Something about that specific dust rocks my world.

Which style are you using? Light, medium, or heavy? I have been looking for this sort of thing for some time, but I haven't found anything this promising...now, even better, I have you to give a review before I try it out. Does it fog your safety glasses? How shweaty does it get wearing one? Do you feel awesome wearing one? :spiderman: Combined with your protos? :alien: These are all really vital for me to have answered before I don one?
 
I'm using the M2 mask with the F1 carbon filters that came with it. I will change to the F2 filters when they are done. I took down a nasty oak yesterday and wore the mask the entire time. It was about 75 out and my body was sweating but it wasn't bad in the mask. Didn't fog the integrated glasses one time and they could hear me fine through the sena. I ordered an XL like I said safety green with black valves. The only way I could look cooler is if it had a scary clown smile on it.IMG_1189.webp
 
Nice! Looking through the details, the M2 is the one I was leaning toward. Looks like it is better for warmer weather, but at the same time still great for the type of dust that we normally hang around. Great. Thanks for sharing Steve!
 
Yeah, great info. I will try these as my normal dust masks just switched away from a downward exhausting only valve and now fog my glasses.

Anyone who has a negative response to a particular tree dust and just wants to not feel sick from that can almost certainly get 'cleared' for it.
