 The profile is so small, you plug it into the outlet. You don't put it in the middle of the room. It doesn't take up a bunch of space. When you plug it into the outlet, it starts working immediately. You'll know where it is because it smells like clean, fresh air, like a thunderstorm rolled through. And what it does is it goes out and it looks for those viruses, the mold, the odors that are in the air, and it takes care of them, goes and gets them. Now, a lot of people will buy the sprays and candles and all that stuff.
