Review on Vremi Premium HEPA Air Purifier for Large Spaces - Eliminates 99.97% of Airborne Contaminants with H13, Activated Carbon, and 3-Stage Filtration - Enjoy Fresh Air Every Day by Kathy Babson

So I only had this item for one day. Until I wake up with a headache like I usually do. The machine is a bit noisy for me (only because I like to sleep in peace), but really it's just white noise. It doesn't bother me too much. I can fall asleep without getting irritated. I love that the features are so simple, they're just a click away. It was a bit difficult for me to open the bottom to take out the air filter so I called my strong son and he couldn't keep up with his strong grip. Anyway, I only gave this air purifier 4 stars because I literally only tested it one night. I will come back in a few weeks to update my review.
