I had no idea what an air purifier was capable of. The symptoms was so easy to set up following simple instructions. Once it turned on its wasn’t long before we could smell clean air from our large living room. We use in in the bedroom at night. It’s quiet white noise, we woke up with sinus’s clear and really felt good. This little machine can really clean a large area. The clean air has what I would say an ocean air. I would never think of going without the Aaria mini. In fact I’m planning on Gifting my adult children with one. Check out the science behind how this works. It’s a great investment to your health.
