This mask provides relief from irritating effects of such nuisance dusts as pollen, house dust, salt and cut grass. Low profile design lets you see where you are going and what you're doing. Easily wear glasses or safety goggles with mask. At only 1/7th of an ounce, it's less than 1/2 the weight of a handkerchief--and far more effective! It's maintenance free--at the end of the day just throw it away. Soft metal nosepiece adjusts to fit closely over the bridge of the nose. Non-woven filter material conforms comfortably to facial features. Breathe and speak normally. You'll be easy to understand using a normal tone of voice. (Not a respirator, does not provide lung protection.)
