the mask is fairly small, appears to be cheaply made especially the rubber strap - this strap will not stand the test of time. had i actually seen it in the hardware store i never would have bought, particularly at the near to $15 price. To me, the price/value would be more apt in the $8 range. It certainly does not look like the pic on amazon - the pic makes it appear larger than it is, the surface area of the filter hence will be limited in it's ability to handle larger volumnes of air over time- but then they want you to buy replacement filters faster.
