Abstract
A composite stove hood filter consists of a primary metal mesh filter and a nonwoven, secondary disposable filter. The secondary filter is a low basis weight (0.2 oz./yd..sup.2 to 1.0 oz./yd..sup.2) spun-bonded polymer sheet which is attached to the primary filter by means of elastic bands or Velcro strips. A patch of melt-blown polymer material, impregnated with air freshener, may be attached to the spun-bonded sheet of the secondary filter to freshen the air as it is filtered.
