  • the graphics 36 are formed from a material that has the same colour as a clean, unsoiled filter 32a (typically white, but may be any suitable colour), but that has different dirt absorption properties than the filter material used to make filter 32a (typically a foam material).
  • the filter 32a is formed from a generally porous foam-like material
  • the portion containing the graphics 36 may be formed from a less porous material or it may be treated to be less porous, such as by silk-screening graphic 36 onto the upstream surface of the filter.

  • the portion with the graphics may remain "whiter" than the foam filter 32a after being exposed to a dirty air flow.
  • the colour of the foam 32a darkens due to the accumulated dirt, the contrast between the filter 32a and the graphics 36 increases, thereby making the graphics 36 visible to the user.
  • the graphics 36 will be the same colour as the filter 32a, and will not be visually obvious (i.e. the contrast between the graphics 36 and the filter 32a will be very slight).
  • the filter 32a will appear like a blank foam filter.
