We like the small 22 pint size of the dehumidifier, as its easy to tuck away when guests come over, but still powerful enough to do its job. Pretty darn quiet for a dehumidifier, keep it mind it does still make a decent amount of noise, but compared to some other units on the market it is quiet. We can run it 2-3 nights for 8 hours before emptying (space roughly 17w.x25L.x10h.) w/floor to ceiling glass on one wall
