Professionals recommend the use of a bigger dehumidifier. Having a larger dehumidifier than the recommended size indicates increased convenience, effectiveness, and efficiency.

However, expect some problems which may arise during the duration of the operation. We'll look at some potential problems and how to address them: 


There are two major components of refrigerant dehumidifiers – the fan and the compressor. When the unit operates, it emits sound produced by the fan.

Larger dehumidifiers do generally produce more noise during operation. However, if your dehumidifier has an option to run at a lower capacity, you may be able to run it on a quieter setting.  

Increased Electric Consumption

You may expect that a large dehumidifier consumes more energy than a smaller unit. This is certainly the case if they are left to run continuously.

However, this is not a real problem with most newer models.

We know you are wondering how this is possible. Many dehumidifiers automatically turn off once they achieve the desired humidity in a certain space. If your unit is large for the space, the unit will quickly turn off, thus saving your power consumption.

If you are using an oversized dehumidifier, look for one with sensors that turn it off automatically.

Extreme dryness

Another problem that you could encounter is the excessive dryness. This happens for manual operation units which lack humidity control.

The dehumidifier will still continue to operate regardless of the required humidity which leads to dryness. In addition, extreme dryness could lead to dry skin, known as atopic dermatitis.

For this reason, it's best to opt for an automatic dehumidifier or be prepared to monitor it closely.

How Big Should a Dehumidifier be?

Excessive moisture can lead to the accumulation of molds and mildew. This is why we need dehumidifiers to eliminate the high level of humidity.

This will prevent the musty smell of your home and protect all of your clothes, electronics, wallpapers, and other essential things.

If the room varies in dampness levels, then it should need a different size dehumidifier. This will ensure that the unit could function efficiently.

This dehumidifier is perfect for medium to large rooms. You can check it on Amazon.

Air quality can be affected in many ways. One of these is excessive humidity. If left uncontrolled, this can lead to several problems inside your home. These problems include but are not limited to molds, peeling paint, distorted wood, and stale odors.

How can you deal with the situation? The answer must be the use of a dehumidifier.

Let's take a look at how to choose the best one for your home.

Check for excess moisture.

Determine the signs of high-level humidity.

  • Foggy windows
  • Moist air
  • Visible mold
  • Rotting wood
  • Severe allergies

If any of these signs are present in your home, excess humidity is a likely culprit. You may want to consider purchasing a humidity gauge or a hygrometer. It monitors the air quality of your home.

Check this out on Amazon. 

For most homes, a humidity level which ranges from 30 to 60 percent is acceptable, but tightening it from 30 to 50 percent will ensure that the home has comfortable air to breathe.

A humidity level that is higher than the normal range should be a call for a dehumidifier.

Determine the problem.

Is your house excessively humid? Depending on the scope of the problem, different solutions may be preferable.

A dehumidifier built into the HVAC system is great for the entire house. It has a drainpipe that empties directly into the sink. However, this type of dehumidifier is not cheap and requires professional installation.

Meanwhile, portable dehumidifiers are cheap and consumer-friendly. You can put it directly onto the wall and operate via a built-in interface which you can easily understand and control.

Many portable dehumidifiers use built-in hoses that drain and pump water automatically.

What size do you need?

Even if the dehumidifier has the same style and design, they can also differ when it comes to their capacity.

Dehumidifier capacity is measured in pints. You may go for a small size that holds up to 10 pints of water desired for a 500 sq. ft. space. Add 4 pints of water for every 500 sq. ft. of space.

For example, for a 1000 sq. ft. space, you will need to add 4 pints to the base 10. This adds up to a 14-pint water capacity.

If your space is particularly damp, it may be better to have a bigger dehumidifier to remove the high level of moisture from the air effectively.
