To start the design of this air purifier is simple and sleek. It doesn’t stick out like a sore thumb. It cleans the air for up to 1200 ft. and keeps the room smelling fresh. The odor neutralizer technology really works and has a nice fresh scent. The display shows exactly what your air quality is. It’s so quiet I have to check to make sure it’s working. I love the display and how easy that controls are to use. I have this unit on the same level of the house where we keep the cat litter box you would not even know there is a litter box down there. I feel better knowing my family is breathing clean fresh air. I have noticed my son who has allergies is having Les issues because we use these. Great job Shark!
