The Shark clean sense air purifier max is terrific. First of all I really like Shark products they are quality made. This air purifier works very well and is very quiet when it is on low or auto in a room that is pretty clean. It is the biggest air purifier I have had so I was a little concerned that it would stand out. With this unit being black it pretty much blends in and the light on the front can be adjusted to bright, less bright and off which is nice. The odor neutralizer is a nice bonus feature. All in all I would highly recommend the Shark clean sense air purifier max to anyone.
