A humidifier too small for 900 square feet will produce very humidity to go round, while one too big will leave your home too moist and condensate. 

The humidifier output is measured in the amount of water (unit in gallons) that the humidifier can produce into the air for 24 hours. To get the appropriate humidifier for your room, first, know the size of that room. In this case, 900 square feet is the size.

Furthermore, check if the room is tightly, averagely, or loosely insulated. A 900 square feet that are well-insulated against moisture loss should require an average output of 4gallons per day.
