I got this a few weeks ago and it has been amazing. I recently moved into a new apartment and the tenant below me smokes. I used to sometimes get wafts of smoke up from the downstairs and they would smell so bad. Since getting this air purifier I no longer have this problem. The smell eliminator on this thing is amazing. 

I think the design is also really ingenious. They designed it so that the filter never really needs to be changed and so that there are two washable filters that catch most of the debris. 

Another fun thing to watch is since my stove has no range hood, I can watch the unit as the particles in the air increase. It goes from blue to yellow to red as the air gets more and more particles and then after I finish cooking it slowly scrubs the air clean.

This is a great product and I suggest it to anyone.
