  • Visual differentiation of adsorbent-loaded media
    Patent number: 6533839
    Abstract: There is provided a three-dimensional adsorbent particle filter having a width, depth and at least one exposed outer face. The filter comprises darkly colored adsorbent particles having an L-value of 60 or less, preferably 20 or less providing a dark contrasting background. Reflective particles are present at the outer face of the filter at levels that allow a user to visually differentiate the filter based on the contrast between the reflective particles and the dark adsorbent particles. Different reflective particle or combinations of reflective particles are used with different filters to differentiate the filters each from the other.
