Review on 🌬️ Alen BreatheSmart: 45i vs Flex Air Purifier - Tackle Dust, Mold, Odors & Pet Dander at Home by Heather Wilkinson

It's hard to give that one star because I love my Alen air purifier, but I decided to get their most expensive odor filter after one of them when I started emitting mold/bad odor from the unit and the room very disappointed. Please note that the device is used in a small bedroom with normal odors. EDIT: I wanted to come back to this review, change my assessment and say I was wrong. The smell I experienced must only have been because it was a brand new filter. Now my room smells great, fresh, nothing. When I leave my room the rest of the house smells worse which is a surprise!
