Cuckoo Air Q Personal Mini Air Purifier, Mobile Plasma Negative Ionizer, USB Portable, Filterless Air Cleaner for Car and Small Room, Eliminates Smoke, Dust, Mold, Allergens, Germs, Pollen, Pet Odors

This tiny thing is better than I expected. Yes, it's small and you probably won't get the same effect using a bigger air purifier, but it does work. It's not too loud, pretty quiet and I've left it one for two days without it getting hot. I left it by my bedside and surprisingly my big room had cleaner air. I'll probably use it a lot during the summer when it starts getting hot and smelly. I do want to buy one for my car and my office cubicle. I think you will get better result when you are in a smaller space!

I love this little machine, it fit perfectly on my desktop at work. I have severe allergies and just recently had my second sinus surgery. I believe this help me to breathe cleaner air around my desk environment. I would recommend this product to those who are looking for something small and unobtrusive for those smaller spaces.

Hard to tell but I think it improves my office air.
