I got my Alen BreatheSmart FIT50 a few days ago, in the oak finish. It is a fine match to my furniture and floor and complements my living room decor. I have it situated at the narrow end of my futon, and it has a small footprint, presenting no cumbersome object to have to walk around. I have my unit set on Automatic. Even when it speeds up to speed 3 or 4 to take care of some air particulates it detected, it is whisper quiet. I can carry on a phone conversation quite near it with no problem, nor does the low level of noise disturb me in any way otherwise. I was told that it would take about 2 weeks for this unit to really make a difference in my asthma, so I reserved an extra star if I find that to be true. So far, I could not be more pleased with this purchase and it really does seem to be helping me.
