Title: Not as advertised
Review: This mask does not appear to be "N anything". Amazon's product description states:"99% filter efficiency against ragweed pollen""filters out 99% of wearer's exhaled airborne bacteria"One might think this mask meets the NIOSH "N99" requirements. It apparently doesn't even come close. The box shown in the Amazon description does not match what was actually shipped in November 2011. The front of my box states, "Filters out > 95% of wearer's exhaled airborne bacteria" and "Helps reduce exposure to household dust, ragweed pollen and yard dusts". There is no NIOSH "N" designation anywhere on the packaging, and the masks' performance criteria certainly appear to be below that advertised.
