Review on 🌬️ Yawkica Portable Air Purifier: H13 True HEPA Mini Air Purifier with 3 Stage Filter & Fragrance Sponge - Personal Air Purifiers for Home, Car, Travel, Bedroom, Office, Targeting Smoke, Pet Dander, Odors by Michelle Lopez

I bought this for my tiny music rehearsal room. The room is on the ground floor with no window so very stuffy. I didn't have high expectations at first, worried that the space would still be too big for this tiny device (it's exactly the size of a water bottle), but it turned out to be amazing. Although there is a battery in it, I usually just let it run 24 hours with the cable. I can clearly feel the difference when I walk into a room, breathing is much easier for me and I notice that the air is circulating, before it wasn't.
