I must say that I was skeptical about this mask. when it comes to pollen/allergies. I did not have any related issues before/after mowing. I'm impressed. This mask hugs my nose/face like a glove, like a face glove. And it comes with an extra set of filters. I didn't have issues breathing. This makes my mow life a walk in the park or in my yard. the only thing he has a problem with is the band needs to be a little longer
