In love with this purifier! It's bigger but I don't think it takes up a lot of space because of its shape. We have 4 cats and there are a few of us that have reactions sometimes to dander.  This air purifier has really been a big help with that. We can tell the difference of the clean air. This purifier oscillates and it puts out a nice fan like breeze. It's easy to use and it tells you on the screen what percentage of clean air the room has. It's surprising what it shows once I turn on the oven or make food! We like this purifier and think it does a greatly job at cleaning the air. I would definitely recommend!!
