Yes, you can. All of the dehumidifier models we’ve reviewed above have internal tanks to catch the moisture. Of course, if you are planning to empty the tank manually rather than using the pump, it may be best to choose a dehumidifier without a pump. The pump models are more expensive, so if you aren’t using this feature, save some money and buy a cheaper manual model. You should also check the tank size, to be sure it will have the capacity to meet your needs. Keep in mind that the larger tanks will be heavier when full, so you may need to empty it more often if you can’t handle the extra weight.
