Great!
Okay so didn’t want to go with the fad, but now I own multiple of these. So here’s the truth, it plugs into any outlet and it’s rather large - like bigger (length-wise) then a newer cell phone. It also gives off a white noise (which I honestly like) however if you don’t like white noise then this isn’t for you. There is a blue light on it that doesn’t give off too much light. So I bought this because I have HORRIBLE allergies and since I bought this I feel like I can breathe again (you’ll know what I mean if you suffer from allergies). If you do I recommend buying one and placing by where you sleep. You’ll see what I mean!  It’s a bit pricey, but for the convenience and the size (way less bulkier than standard devices) I highly recommend. Also every 6 months you have to change out the filter. So keep that in mind. I don’t have pets so I don’t know how it works with pets.
