Quickly cleans my house with any pet hair in the air or allergic dust. This air purifier gets to work telling you on the monitor the quality of your air and than fixing it. It’s easy to assemble & has different level modes of how low or high you wish the purifier to work. It’s display is easy to read in the night, as it lights up. The machine itself is rather large but it’s circular shape makes it ideal for storing in a lot of places. I feel my air quality in my home has been a lot better since using this product. It also makes a nice fan in my home for the summer circulating air which is an added bonus!
