This works so great and really gets the air clean. So simple and easy to use. The design is so nice and it is super quiet. I like that you can see the quality of the current condition in a simple display. It is amazing how you can tell such a difference from the first day of use. Has so many nice features. Seems of high quality and great value. I am sure to get years         of use from this. As always Shark never disappoints with their great products. Highly recommend.
