Didn't work for me.
I was excited to receive this product.  I had ordered two of them. I put one in two different areas of my home (baths) and didn't notice any difference in either area. I tried two in one smaller area and still didn't notice any fresh air smell or any difference in this area. Don't know what the problem was. The service from this company was quick and on time and the product had a good look and  I really thought it wold be great. It wasn't.
