Too Small.
The airflow for this unit is too low to achieve a decent room air change per hour.  I doubt it could even do a 10' x 10' room air change in an hour and is only cycling air close to the unit at best.  It has a bright blue light while in operation that you can not turn off which I find distracting and unpleasant to sleep near.  It might be effective on a desk say 2' away from your face.  The fan is audible.
