This is our third Frigidaire humidifier in three years--each one lasts just over a year then dies right after the warranty ends. We keep buying them because they are quieter than the competition (we use it in our finished basement so we need it to be quiet) and they work well while they are working. This one does make a weird electrical buzzing noise when the compressor starts running, which we are hoping is normal. It has a good capacity and is fairly easy to empty.
