LOVE THIS DEVICE!!!
I purchased one of these to try it out.  It works great!  Unless your home is sterile enough to perform surgery on the dining room table, (no home is that sterile...not even Adrian Monk's!) you should have at least one of these in your home.<br />A friend of mine has a 2 year old daughter with chronic sinus problems.  I told my friend about this air sanitizer.  She bought one and plugged it in in her daughter's bedroom.  No sinus problems ever since.  Her family even bought four more of them and installed them throughout the house!<br />They also make great night lights...not too bright or too dim.<br />Yes it has a small fan to circulate air through the bottom to the top of the device.  If the air sanitizer and you are in the same dead silent room, then yes, you can hear it.  It is about as loud as a mouse burping.  (i.e. very quiet).  If for some reason, the device is keeping you awake while you are trying to sleep, just move it to another room while you sleep.  Easy.<br />Bottom line...which is better...$35 for this excellent device or THOUSANDS of dollars in hospital bills because of respiratory illnesses?  It was an easy choice or me.<br />I also purchased a spare bulb.  The device consumes just 9 watts of power (that is only 2 watts more than most traditional night lights) and it sterilizes 465 cubic feet of air per hour.
