“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? How do dehumidifiers work?

These questions 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:

Waykar 40 Pint Dehumidifier

The Waykar 40 pint dehumidifier is the best 40 pint dehumidifier you can buy. It's whisper quiet operation makes it a great choice for living rooms, bedrooms and studies alike. 

  • Quiet operation
  • Very lightweight and convenient design
  • The tank is quite small, as well as a bit tricky to empty or put in a level position

Runner-Up: LUKO 40 Pint Dehumidifier

Second of our trio of 40 pint dehumidifiers is this LUKO model. This model is a small wonder that will be happy to dehumidify your home either continuously or at 35% - 85% humidity settings (at increments of 5%). The continuous option is provided via a hose outlet, but a hose is not included. Don’t take this as big negative, this is standard practice with dehumidifiers. You can either buy a hose separately or use a suitable garden hose.

As for the LUKO’s other features, it has an indicator for when the water bucket is approaching full capacity as well as an auto shutoff function for when it does. This model also has a Memory IC – this is an auto restart option that allows the dehumidifier to restart on its own with its last settings in the event of a power outage. This dehumidifier also has 2 fan speeds – Normal and Turbo. It is small and light, as you would expect from a well-designed 40 pint dehumidifier and is easily portable.

Here are some additional pros and cons of the LUKO 40 Pint Dehumidifier:

  • Quiet operation
  • Effective and efficient
  • The tank is quite small and requires frequent emptying if you’re not using the continuous draining feature

Alternative: Danby 40 Pint Dehumidifier

Danby round up this trio with their 40 pint dehumidifier. This UL-listed little worker has a 6.3-pint water tank capacity which isn’t much, but that’s standard for a 40 pint dehumidifier, as you can see from the previous two entries.

It has a full tank alert, as well as an auto shutoff feature that stops the dehumidifier from working when the water tank is full. For continuous drainage it has a hose outlet that can work either with a (separately purchased) dehumidifier hose or a suitable garden hose. This model works great with relative humidity set points between 35 and 85 percent in 5 percent increments. The removable and washable air filter is reusable and ensures perfect air quality.

This dehumidifier also has the standard auto restart feature in the event of power outages, as well as an auto defrost function to prevent its inner workings from freezing and damage. It also has a 24 hour programmable timer and two fan speeds.
