I dusted my entire bedroom before I set this up. My bedroom gets very dusty and quick. My dog sleeps in my room often so there is also dog hair and dander. I've been running on medium setting for about three weeks. I've noticed that there is less dust on the furniture during this time. It's definitely made a difference. The design is modern and sleek. Small enough to fit almost anywhere. UV light is a great feature. Buttons are easy to use. I keep the instructions close by so I can easily access to change the settings.
