I like the air halo, it's convenient to wear around my neck, it cleans the air for me and I'm able to breathe better. It has no noise, I received this little gem on Friday, January 28, 2022, and I started using it that same day and night, I placed it on my nightstand at night and during the day I wore it around my neck. I suffer from Asthma so this came in handy and really helps a lot. At first, I was hesitant but after using it, I found that it actually works great. I highly recommend it!
