This mask is designed with double layer filtration for assured protection against all forms of pollutants and germs. The first layer is made to protect you from larger pollutants and particles; the second layer protects you against micro-organic pollutants and germs. Double layer filtration leaves no room for harmful infiltrations.
Made of breathable water resistant material, allowing you to wear them irrespective of your proximity with water and other liquid chemicals as you work or go about your business. You may sweat while wearing this but this will not affect the mask in any way.
