Customer feedback reports that the filter works well, with dust and cooking smells mentioned as examples, and some customers consider it worth the money. These are reported impressions rather than verified performance results. They may matter to buyers seeking routine replacement media, but the listing does not provide measured filtration performance. The overall ratings are mostly five-star, with a smaller spread across lower categories, so experiences are not uniformly positive.
