Pure Enrichment PureZone Mini Portable Air Purifier - Cordless True HEPA Filter Cleans Air & Eliminates 99.97% of Dust, Odors, & Allergens Close to You - Cars, School, & Office (Blush)

I absolutely loveThis purifier. is great for if you are in a car with a smoker and a pet dog it also takes out musty odors, and I also use it when I travel. i’m not sure if you can use it on an airplane like have in your carry-on, but I used it on a bus or in a hotel.

Perfect for my work cubicle. It ventilates the air and is not too loud. It really helps my eyes not to burn from allergies, in the air.

After being sick consistently every month this year I decided to get a tiny air filter for my desk in my small shared office. Including using it I have noticed it eliminates gross smells from the microwave, cigarette smoke and overall I've noticed absolutely zero flu symptoms since using it. I can't tell if it placebo or not but I've been enjoying it. It is pretty affordable and able to be moved around extremely easily as it's the size of a water bottle. Also taking it to a hotel I felt as though I could breathe easy knowing that there was (hopefully) fresher air near our bed. There are 3 settings low, medium and high and I love that you can still use it while it's plugged in if it dies as I use it for my 8 hour shift and sometimes forget to plug it in at night to charge.

I purchased this air purifier because I used one that I borrowed on a recent trip. In fact, I liked it so much that I ordered one as a Christmas 🎁 gift for my daughter.

If you have very small area, I guess this might work. Plus it takes constant charging.
