Title: Quiet and Very Efficient
Review: I've now had this humidifier for a year.It is extremely efficient. With a new filter installed I have had as much as 8 gallons of through-put (water put into the air by the unit) in 24 hours. The efficiency is such that I seldom have to run the unit at the highest fan setting. (This is the only one of the three settings at which you can hear the unit from more than about six feet away.)Water hardness where I live is such that, even with relatively non-drying heating system (hot water radiators), the amount of through-put means the filter needs replacing about once a month. This is an expense you will have with any evaporative humidifier, so should not be counted as a negative for this product. The unit will not indicate a new filter is needed. Just pay attention to length of fan being on--when the fan is on for long periods but little water is being used, it's time to replace the filter.I would purchase this product again in a heartbeat.
