Tips: how to choose right gas filter masks


It would be a wrong concept that the more expensive or the thicker the masks are better. There is a simple method to check whether your masks are good for you. Try to press your mask tightly on your mouth and nose and then take a deep breath to test its ventilation. If you feel hard to breathe, this mask must be not your MR.right. Wearing a poor ventilating mask has nonsense because you have to inhale air from the gap between your face and the edge of mask which can not protect people from the dust and small particles. Besides that the most simplest way is to clean your nose at night, clean nose means good mask while dirty nose means mask with poor dust resistance.
