PureZone Breeze Tabletop Air Purifier is great for a small room or office. It is light weight and easy to move and made very sturdy. It has 3 settings. On the lowest setting I can't hear any noise. The highest setting is a little noisy and vibrates the table. When it on you can feel the cool clean air coming out and it smells fresh. This air purifier is great for small spaces to help clean the air of allergens.
