Question: Does this mask work to capture sheetrock sanding dust?
Document: Mask fits nicely, keeps the dust out and helps me breath when I am done sanding. Shake out the mask and go back to work. Filters last a while
Use this mask for prep work as a painter. Lot of grinding and sanding this summer. Keeps the lead dust out, with fresh pads it works great. As people have said it can get stuffy but hey it is a rubber mask, Ive done 8 hour work days taking it off only for breaks and such. It is even roomy enough to allow for large dips of copenhagen. Make sure you get some good eyes and ears and this mask will do the rest.
These work great. They really keep bad dust from entering your lungs. My only complaint is the dust canisters clog quickly. I started using this mask for some light demolition (removing lat and plaster). The canisters clogged too fast for this application. On the other hand, I removed vermiculite wearing this respirator.
I'm no professional woodworker or anything like that, but I do work with MDF upon occasion, and I know that the dust from cutting that material can be toxic. I've got a big head, so finding dust masks that fit is always a problem. This is the first mask that I've found that I can wear for significant periods of time without real discomfort, nor leakage that I've detected.
I work in a shingle factory and encounter high levels of dust and fumes everyday. The paper disposable mask provided at work do not fit tight and and uncomfortable .. this half mask is just what I needed, it has a snug fit and I wear it for hours at a time without discomfort. The filter also makes life much easier to breath and I can feel the difference at the end of the day if I'm not wearing it. Overall I would recommend this this product ...zak p.  MN
I needed this for my woodshop use after finding out that many sawdusts are toxic to the respiatory system. Works great for my recent dust raising and varnishing projects. More comfortable than the cheapie paper dust masks, and long lasting. No more lung clearing hacking after sanding. Love it.
I ordered this dust respirator to use while woodworking. Finish sanding generates a lot of fine airborne dust, and everyone that is exposed to this should ware dust protection gear. So far I like this device, it's not too heavy, seems to fit reasonably well, and air flow while breathing is less restricted than with the simple paper masks. The replaceable filter elements are reasonably priced. It also seals around the nose and face better than the paper masks, and should be less expensive to use.
i got this to do body work so i do not have to breath bondo dust and paint out of the air and it is very comfortable
I bought this because i work in the export grain market.we have alot of places that this comes in handy.Grain dust is a killer but not with this! !
A must have in the shop. I'm impressed with the build quality and ease of use and fit. The filters swap out easily. The mask is comfortable, the rubber is soft and I love that I can easily hand wash the item. Most importantly, I don't feel like I'm breathing underwater.I'm a woodworking, boat building weekend hobbiest and use this when sanding epoxy and varnishes.
