I am considering whether to buy this product, and should address an earlier review (by someone else) about this product.40 pints equals 5 gallons. Please measure how much space this will occupy!The unit dimensions place the unit's physical voume between 2 and 3 cubic feet. 1 cu. ft. of water is 7.5 gallons approximately, so the volume of the unit would indicate between 15 and 22 gallons of water. However, the unit has to house the mechanism/motor etc., so the actual cubic footage of the water holding unit MUST be less (no more than 1 cu.ft). This implies a maximum holding capacity of 7.5 gallons = 60 pints.We want DEhumidification, so why store that much water in a pail? Since the water is being drained (via gravity or pump), the pail can be much smaller/lighter.How much water is extracted will depend on the relative humidity indoors and ongoing external conditions (rain).A 40-pint holding capacity unit will weigh a lot more than 30 pounds without the water!
