And if you don’t know exactly what size of dehumidifier you need, that’s probably where we should start from:

The size of the dehumidifier is categorized by how many pints of water it can draw from the air within a 24 hour time period. A 70 pint dehumidifier draws 70 pints of moisture, while a 30 pint dehumidifier draws 30 pints. 1 pint is equal to 0.125 gallons and 0.47 liters.

In terms of how many pints correspond to how many square feet of physical space, this is a bit trickier to calculate since the level of moisture in the air can vary considerably.

Generally speaking this is how pints and footage correlate:

  • A 30 pint dehumidifier is suitable for 300 – 400 square feet of space, depending on the moisture levels. 
  • A 40 pint dehumidifier is suitable for 300 – 500 square feet of space, depending on the moisture levels. 
  • A 50 pint dehumidifier is suitable for 500 – 700 square feet of space, depending on the moisture levels. 
  • A 60 pint dehumidifier is suitable for 500 – 1000 square feet of space, depending on the moisture levels. 
  • A 70 pint dehumidifier is suitable for 700 – 1500 square feet of space, depending on the moisture levels. 

Once you’ve figured out what size and power dehumidifier you need, the main first step is done. After that comes a simple choice of quality as well as a choice of what additional features and functions you need and like. Different dehumidifiers have different size water containers, they have different options for continuous drainage, they have different energy efficiency, use different refrigerants, have different control displays, and so on. A lot of these features are a matter of personal, subjective choice, while others are objectively great to have.

Take a look at the 5 choices below and you will get an idea of which is the best dehumidifier on the market right now. If anything catches your eye – great, we’ll be happy to have helped! If you want more options, check our other product lists and reviews as well.

​Dehumidifier Buying Guide

Buying a dehumidifier should be a straightforward task but we often receive requests for assistance from buyers who are struggling to ascertain exactly what it is they require from their dehumidifier other than humidity reduction.  

This section is designed to clear up much of the confusion that shoppers have - and in conjunction with our earlier dehumidifier recommendations – should be sufficient for you to feel confident in purchasing the perfect dehumidifier for the task at hand.

Dehumidifier Capacity

In the preface of this article, we covered the sizing categories which are typically attached to each dehumidifier which relate to how much moisture they are able to extract from the air in any 24-hour period.

Well, in this section, we wish to go further and provide you with a recommendation that will cover every eventuality;

“We suggest always purchasing the largest dehumidifier that you can find, regardless of the size of the space that you are trying to dehumidify.”

For most people, this will mean that a 70 pint dehumidifier (the largest consumer size available) is always the best option, whether for a large open plan living room or a small office. And the reason for this is simple; larger capacity dehumidifiers are more efficient because they can reduce humidity levels much faster than their smaller equivalents.

If a 70 pint dehumidifier can remove 70 pints of moisture in 24 hours and a 50 pint dehumidifier can remove 50 pints of water in 24 hours – the larger model must be removing water at a much faster rate.

For example - if you had a space which contained a volume of air which held 100 pints of water, the figures below will demonstrate just how quickly each model classification would completely remove the moisture from the air;

70 pint – 34 hours

50 pint – 48 hours

30 pint – 80 hours

CFM Ratings (Cubic Feet Per Minute)

Another important specification for any dehumidifier is the volume of air that it can process on a per minute basis. A higher CFM rating essentially means that a dehumidifier can suck air from a greater distance due to the power of its fan than a lower rated dehumidifier.

Larger dehumidifiers usually have a much better CFM rating which is another reason why we suggest purchasing the largest dehumidifier you can.

Energy Efficiency

Tying into our previous point; dehumidifiers run on electricity and are often required to run for extended periods of time. For this reason, a dehumidifier that gets its job done faster means that it can switch itself off and go into maintenance mode faster, essentially lowering your electricity bills.

Reliability and Longevity

Generally speaking, the shorter the duration that a piece of equipment has to operate for, the longer it will last. Mechanical parts wear out over time and will often need to be replaced – but since a larger dehumidifier will run for a shorter amount of time, this should in theory mean it will be able to provide you with reliable service for much longer.

And we think that this theory is backed up by statistics as you will notice that consumer complaints about dehumidifier failures almost always concern smaller capacity models.

Drainage Options

The last point for consideration concerns just how you intend to use your dehumidifier.

All dehumidifiers need to store or discharge the water that they collect and will shut off automictically if unable to do so.

What this means for you is that if you intend to leave your dehumidifier running for prolonged periods of time, you will need to ensure that you have provided a way for water to drain away, whether into an internal floor drain, a very large bucket or tank or somewhere outside.

If you only intend to run your dehumidifier for a few hours at a time, the internal water tank will be sufficient.

​Conclusion

And there you have them – the 5 best dehumidifiers on the market right now in our experience. If we had to pick one, we are partial towards the Frigidaire brand which has topped several of our other reviews, however, the other options are amazing picks as well.
