Product review (4 stars): An Adequate Filter
The item description did not mention a carbon-based odor trap.  The filter does have that odor-capturing component. The "carbon-element" in this filter is a lightly-woven fabric of strands of carbon, not carbon granules as found in old-style filters.  The filter seems light weight (thin).  I purchased this filter because, even with shipping charges, it was less than the same filter at a storefront.  All in all (function and price) this filter is the best of what is now on the market for un-vented range hoods.
