I use this air purifier everyday in my home office and it helps tremendously with the air quality. I have really really bad seasonal allergies and my office is in the back of the house and gets dusty really fast. It was very easy to assemble and has a decent filter on it. The machine is durable and made with real quality. The stainless steel is easy to clean and the filter is easy to clean when it’s dirty and goes right back in when it’s dry. It is perfect for small spaces as it’s compact and sits on the table surface and is never in the way. The machine is quiet when it runs and has clean sense IQ that automatically adjusts to the best setting to optimize clean air. I love shark brand and this definitely kept the bar high for other purifiers.
