Pros:

• a smart fan that can clean the room by capturing the air pollutants that pollutes the room and then releasing a clean air afterwards. I definitely need this for my room to stop my nose allergies
• a very cool design that has no fan blades.
• also has a partner app for. your smartphone to track the status of your home

Cons:

• needs maintenance ( the filters will eventually be full of pollutants that will block the airway)
