I like this item. It does a great job of filtering the air in my 600 sq ft studio. I often light incense. As a test, turned on the air purifier and placed near the source as instructed. Air was fresh in a matter of minutes, and the entire room in no more than 10. Easy to clean. Wipe down some parts, vacuum others. No filters to replace. Manufacturer recommends replacing UV bulb once a year, but aside from the minimal electricity it uses, that is the only expense you should incur. Minimal price, maximal benefit. I highly recommend.
