Query: works well

Own a couple of these for office room and home, very happy with it.Use it a lot in the winter months, partly due to dry heat from the AC(irritates and swells nasal passages) and also due to the reason that I live in the allergy capital of the world (dry eyes, sinus issues, hay fever).I fill it up every day and keep it running and humidifies the room very well. You may want a couple if you have a large large rooms or in living areas, it works well in my office which about 14ftX12ft and bedrooms ~ 20ftx20ftIts funny to read the negative reviews. Not sure what people expect out of this for 10-15$, but it blows steam as required, 1.5 gallons over 10 hours. cleaning is easy and best bang for the buck .
