I received this item a few weeks ago and this is my first air purifier. I'm obsessed and now need on in every room! I love that it has an app you can use to control it and set schedules to have it automatically run. I keep this air purifier in my living room and within a day I noticed the air quality was much better and it just felt and smelled cleaner. Its also really easy to clean and change the filter. Very impressed with the product and looking forward to purchasing more for other rooms in my house.
