I love this air purifier. Well I guess I should’ve known because I love everything from this brand. It is easy to set up right out of the box, the instructions are clear. It works amazing! I had no idea it covered such a large area. I keep it close to mine and my boys bedrooms. It gives off the lightest scent, as it’s working. But it’s just a clean light scent. The display will tell you how clear the air is up to 100%. This has made a world of difference in my home.
