This Tabletop Air Purifier is literally a breath of fresh air. You can feel the air quality improve minutes after turning it on. It's quiet, not an eye sore and very useful in a good open size or even closed off room. This is used in our living area where we spend a lot of time. It has a HEPA filter and 3 different speed settings to help control the flow. Well worth the use especially if you suffer from allergies!
