Can this mask be worned under a welder's helmet comfortably? Will it require filters?Marie
This is a filter mask, not a respirator with canisters to replace. The mask should be replaced often to insure proper filtration of particulates.It should fit under a welding helmet, and if so, it can be used with a helmet. "Comfortably" will be determined by the amount of clearance your helmet allows. I use these filter masks regularly, and they work very well. I buy them by the box.I hope this helps you with your decision.
should you wash these when they get dirty?
I use these for sawdust, and sometimes blow them out, from the inside, with a small-orifice "air-gun" at about 100 psi, which works pretty well. Be mindful of what you are removing, however, and where it's going, and do ANY air blasting with care! I doubt they would respond to washing in any satisfactory manner. lester
Great to use while sanding wood and non-metal items; not for painting or hazmat use. The seal tends to fail in high moisture conditions over time but the product is inexpensive enough to replace as needed.
Mask works well.
To expensive here.
Great job easy to breath
compaired to other filters this one fit my needs and works well with two head bands. I use it with blowing dustout of the shop, sanding, and sawing. Outside of boat work also great sanding drywall. Would hightly recommend this product.
