Before You Buy What You Need To Know 

You’ll see our top picks dehumidifiers, which are the recommendation as researched by team, but before that, we need to take you through an important aspect where people get it wrong when choosing a dehumidifier for various purpose – we call it dehumidifier coverage capacity. When you understand this dehumidifier capacity concept, it will give you a hedge to identifying which dehumidifier pint capacity model to purchase.

Okay, let’s start.  What is a dehumidifier capacity? Recall earlier, we said, dehumidifiers are of capacity. Therefore, the moisture level (in pints) a dehumidifier can remove from the air in 24 hours referred to as the capacity. In order words, not all units can remove the same amount of condensation.

For example, though we illustrated earlier that compressors dehumidifier has the power to outtake up to 10 (ten) gallons per day but doesn’t it mean, all compressors models have the same capacity to take out such amount of wateriness. Some can be 8 gallons or lesser, which is what we’re trying to explain to you.

Please note, you might not see the capacity written in gallons, rather in Pints because the term used when it comes to dehumidifiers is pint number, while in humidifiers it is called gallons.

Nevertheless, to know what the moisture level a particular unit can withdraw, check the dehumidifier manual. All manufacturers state theirs on the instruction booklet. 

To conclude this section, the possible compressor-based dehumidifiers that are found on the market range from 30 pints dehumidifiers (30pts can extract 3.75 gallons), 50 pints dehumidifiers (50pts can extract 6.25 gallons) and 70pints dehumidifiers (70pts can extract 3.75 gallons)        

How Do You Know The Right Capacity To Buy?  

Knowing which one to buy for a particular area application has been a notable problem among consumers, especially for those who cannot determine their home size. A dehumidifier sizing chart can help you solve this issue as believed by the public. Many sizing charts developed by a different scientist can be found online but one of the most widely accepted is the one given by the Association of Home appliance Manufacturers (AHAM). This Association is responsible for checking the energy efficiency and testing and approving the moisture removal capacity of sampled dehumidifiers manufactured in the states as claimed by manufacturers. Since AHAM has been trusted by most consumers, people seeking dehumidifiers use the sizing chart provided below as a guide to fetch themselves the right unit for their facility. 

This chart is not a property of

Explanation of this chart is as follows.
  • Moderately damp: This is applicable for damping spaces characterized by musty odors in humid condition.
  • Very damp space: When your space is constantly damp with must odor. Damp spot can also be seen on walls and home floor.
  • Wet: Your space feels wet with signs of sweat on walls, floor, etc. 
  • Extremely wet: This includes wet floor, walls, and heavy moisture build-up.

Though, this chart has been seen helpful in time past because people don’t know the lapses the chart has. We have therefore recorded the following things why we don’t support the use of this table above for choosing the best dehumidifier.

From our findings, we could not lay claim to any page where it is available on AHAM websites.

The chart starts from 500 square feet and ends at 2,500 square feet, whereas there are cases of a room having square feet lesser than the minimum value. What about a bigger property that is up to 6,000 or 7000 square feet as regards to industries or commercial environment? For instance, these units does not fall into the ranges as stated. Therefore, this chart will fail by looking at the coverage. As far as capacity is concerned, only 30 pints dehumidifiers fall into the claim on the chart. And as of today, we have 70 pints, 50 pints and higher pints units whereas 10, 17, 26, 37, and 44 cannot be seen on the market as such we don’t support the chart.

In reality, 70 pints dehumidifiers are for homes from 1000 – 2,500 square feet up but the so claimed AHAM table stating 44-pint dehumidifier is ideal for Extreme wet case in such range. This information is not correct, besides there are no units designed with 44pint capacity mist removal. Hence, we believe the chart was used for a scientific study of a particular study of which all household conditions cannot exhibit the same moisture phenomena. However, the data given are from extrapolation of a test in experimental design involving moderately damp, very damp, wet and extremely damp.

What’s Our Decision and Recommendation?

If you have taken time to read through the above argument, you would have seen reason to agree with us that the AHAM dehumidifier sizing chart has its limitations. Because of the gap discovered in our course of dehumidifier study, we cannot advise you to fall back on that chart in choosing the best dehumidifier for any purpose. So what is our recommendation on what size of a dehumidifier to purchase? Find out below.

Choose a largest size unit

Irrespective of the degree of wetness or home size (from 1,000 square feet and above), a 70-pint unit which is the largest capacity for home use is going to do the work perfectly. 

If your space is below a thousand feet whether the area is very damp or not, our suggestion is between (50 & 30) pint dehumidifying appliance.

Another thing that matters most in choosing the right capacity as the best dehumidifier is a factor of the price. Also, take note, the higher the pint number, the faster and the moisture removal power. That is 70pts unit is faster than 50pts device and so on as the number of pint decreases.

Can I use a commercial or industrial dehumidifier in the house?

Though commercial/industry standards can be quiet to an extent depending on the brand, we do not advise you buy this for controlling humidity at home. They are very powerful and can make your house dry out, causing another problem of reduced humidity, which may require you adding moisture again.

To avoid a low humidity environment that causes sinusitis, congestion, dry skin, and other related symptoms, it is, however, wise to adhere to standards. 70-pint unit is the maximum for indoor unless you want to dehumidify your crawl space then you can opt for a machine with higher withdrawing capacity.
