Could you help with an issue?  I have purchased the 30 inch 400 CFM Convertible Wall Mount Range Hood with the carbon filters so it could be vent less; however when we were putting it together we discovered the Carbon Filters would not fit one side.  When I called the distributor; they told me that is a known problem and I will need to return the Range hood and get a different one.  I don't want too.  I love the range hood but I can't currently afford to convert it to vent outside (plus I have already thrown the box away for the range hood).  What can I do?  Are there different filters that I can use?  Any help would be appreciated.
