I love this Shark air Purifier and everything it does! This one is small and compact so it doesn't take up much room at all. The fans are quiet and powerful. I have found it takes less than an hour of running in each room to reach optimal air quality. The setup was super easy and quick. I can move it room to room no problem. The screen gives you a ton of info on your air quality from which types of particle it picks up to how much time remaining to clean air. My favorite room for this is my teens room as I have noticed a huge difference in odor after using this for just a few hrs! This is a something I never new I needed in my home but now can't live without!
