What a great product.  One note before I get on with the good stuff.  It's called a Mini but it's 21 inches tall.  It's a very nice looking unit that will look good in any room.  

It cleans the air.  I don't know exactly how it works but the air that comes out of it is "fresh."  The air is so very clean.  I never thought I'd notice how beautiful the air is that comes out of it but it really is quite an improvement.  They've done a great job with this product - a nice looking part of any room and the cleanest, freshest air you will ever experience.  

It has three speeds but I must say that the highest speed is noisy.  It's moving a lot of air so that makes a sound.  Easy solution is to keep it on low when you're gonna be in that foom for a while.
