I received this as a sample product to try and found it to be high quality. It was fast and to set up. The easy to read panel has a bright on light so its easy to tell if it is on and at what level the fan is set. The device comes with a back handle that makes it easy to lift and move the HEPA filter device around. I like the sleek curved edge form because it looks elegant. I really like that the filter can be washed and the uv light changed out if needed. The device can be set to run at 2, 4, or 8 hours or continuously. The best part is that it captures and destroys allergens, formaldehyde, benzene, germs, viruses, bacteria, and mold. I got the best sleep of my life after using the device the first time.
