“40 pints” stands for the amount of moisture the dehumidifier pumps out of the air in a 24 hour time period. 40 pints is roughly 5 gallons or 19 liters. That is typically enough for an area of 300 – 500 square feet of space, but can be enough for more too, depending on the level of humidity present.

So, if 40 pints is the right size for your home or storage space, now is the time to look at some of the other features of a dehumidifier. How big and easily portable do you need it to be? Does the noise level matter or will you use it just for your basement or garage? What drainage options would you prefer, how would you rather drain the dehumidifier – with a pump or a gravity drain? What is the temperature range that the dehumidifier will have to work at?

These may sound confusing, but they are not that hard to figure out. So, let’s look at some of the examples of the best 40 pint dehumidifiers and figure out their features together:
