This air purifier really helps my house to smell fresh and clean. We have three cats and a medium size dog. While I wouldn't say our home's odor was offensive before, there was always a little lingering animal smell, no matter how clean I kept the dog and cat boxes. This has fixed the issue. I placed it near the cat boxes, and it does an amazing job, and there is no more odor at all. It is also attractive, which I love. It isn't some big, ugly, clunky machine. While the wi-fi option would be nice, I don't feel like it was really a necessity for our family. I highly recommend this unit.
