Shepherd Filters are disposable kitchen grease filters made from Australian wool.
Yes, filters are designed to retrofit to existing kitchen hoods.
In terms of food safety, as the Shepherd Filter has no real direct contact at all with the food produced, there would be no risk.
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.
Our product has been tested, listed and certified to all or more of the same standards that your current metal filters have been subjected to. With that said, the liability should not change at any level.
If the Shepherd filters are maintained properly, you will experience much cleaner kitchen exhaust duct and canopy, and Kitchen duct cleaning will be greatly reduced.
