What impact does this have on the existing hood certification and insurance coverage?
Based on the relative position of the filter in the hood and the Shepherd Filters construction, as well as the fact that the filters are made of wool, a non-combustible material, the use of the UL listed grease filters in an existing hood will not alter the hoods function or operation, or infringe on the certification of the existing hood.
