The Wpro Range Hood Filter 2-in-1 47x57cm is a multifunctional filter. The filter is made of mousse covered by a layer of carbon. This way, the filter not only absorbs fat, but it will also take care of nasty odors. You can cut the range hood filter 2-in-1 to size yourself to make sure it will always fit into your range hood. If your range hood is wider than 60 centimeters, you'll need 2 range hood filters.
