I'm so glad I got to sample this product, it is incredibly effective at maintaining a good air quality in my home. I often struggle with dust allergies and even using a duster sometimes just can't catch the particles as well as I need but this Levoit Air Purifier steps in and does the hard work for me. It's not heavy so I can move it around the house as needed and it's also incredibly quiet, sometimes I forget it's even in the room!
