I have never been more excited to receive an item! A friend recently bought one of these and I was researching the market for an air purifier. Once I got it, I made sure to deep clean my room and dust everything down. I closed my bedroom window and left the machine to do it’s magic! I have the hottest room in the house and it gets a muggy, musty scent after a few hours I was insanely impressed with the difference! I was also excited to know it’s Bluetooth and app capabilities so I can control it even when not home.
