I think this is a really great unit for a smaller space. I have 1 running in an upstairs appartment and it is doing a really nice job. Outside it's almost summer in Illinois and its 70 degrees. 
The one thing I will say about this unit is that the filter rattles when placed in the correct location, if you pull it out slightly the rattle stops. Just poor filter placement design I think. Other than that, decently affordable unit.
