The Shark Air Purifier is surprisingly very large unit , it comes with a much appreciated remote control. I loved that this product is not only an air purifier, but a heater as well for the winter season. This product is attractive, and is easy to set up. The air purifier setting works quickly and very well, but the fan settings air flow is poor. The heater warms up a room nicely. I would be very impressed with this  product, but I have one issue. There was a terrible chemical smell when I first turn it on, the  poor air quality light came on. It still has a light odor after using it several times.
