Less than $1 each for a 3M N95 mask is a good deal in my opinion!
For the $9.64 price Shipped and Sold by Amazon you may need to check out the "other sellers on Amazon" for purchase, the default seller is $17.99 for me.
These have valves, so they are ideal for Construction, Woodworking, and the like.
