    摘要: A filtration system for filtering particulates from air. A plurality of point ionization sources are positioned in the proximity of the periphery of an air flow channel and being oriented to generate ions in the proximity of the air flow channel in a direction generally upstream from each respective one of the plurality of point ionization sources. A particulate collection surface is positioned within the air flow channel in a downstream direction from the plurality of point ionization sources. The particulate collection surface is electrostatically charged in an opposite direction with respect to ground than the electrical charge of the ions. An ion trap is positioned within the air flow channel between the plurality of ionization sources and the particulate collection surface. The ion trap is relatively electrically neutral as compared with the particulate collection surface and the ions.

    摘要: 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.
