I received this product free to review and i could not be more happier with its performance. I currently live in a 900sq. ft apartment. I started by testing this out while making dinner the other night and you could barely know i had fried porkchops. Then last night I used it in my room as i have a dog that sheds. Both times i felt this product did what was needed. I thought it would be smaller than what arrived, but happy that it does the job!
