The cost of a SEIPACX Mask can be washed 1000 times.
Less than $00.03 per use. You can not buy a disposable mask for 3 cents and this mask is far superior to a paper mask.

I suffer from allergies. Grass pollen is the worst for me. I hate to take drugs for my running nose and watering eyes, so I wear the SEIPACX Mask. At first I wore it only in the back yard when I was cutting the grass, were no one could see me. But it is so comfortable to wear and works so well my eyes and nose are now fine when I cut the grass. I wear it now in the front and back yard.
