Product review (4 stars): It fits and works well
I really can't compare this to other filters as this is my first replacement. My range hood came with a thin cheap metal filter that I frequently wash but it was starting to come apart. I ordered this filter basically because it fit and I felt the price was ok. The product description was pretty vague and I didn't even realize it was a charcoal filter and was slightly thicker until it arrived. While it may not be as efficient as higher priced units I feel that it is definitely a step above the thin original one so I am keeping it. It fit the opening with no problems and does not seem to impede air flow or create any unwanted noises so I guess only time will tell how well it filters the elements.
