I have been using a small air purifier for a year prior to getting this purifier and wanted something that I could move off of the floor due to pets that shed.  I really love that this air purifier is versatile and can either be used on the provided stand, or easily removed as I have done with a flat head screwdriver.  It was extremely easy to install and that settings are extremely user friendly the only criticism I have is with the guide.  It is regarding the ion setting.  I feel that the guide needed to identify the difference between the positive and negative ion setting and the benefit.  It just glazed over this like it was common knowledge.  This was not a big deal though.  I have been really impressed with how easily it has blended into my decor and how quiet the operation is based on the size.  I will definitely be recommending this to others.  I have been very pleased so far.
