  • Filter mat for the passage of contaminated air
    Patent number: 8016905
    Abstract: The invention relates to a filter mat, which is used in applications where it filters the flows of contaminated air that pass through it. In such mats, there are points where aerosols collect. This is disadvantageous as it lowers the efficiency of the mat.
