What to Consider When Buying the Best Dehumidifier for COPD

a) Capacity of Dehumidifier

Best Dehumidifier for COPD

Here, we are not talking about the actual physical size of the dehumidifier.

Rather, capacity refers to a dehumidifiers ability to extract water from the area within 24 hours.

The most commonly used capacities are 25 pints, 50 pints and 75 pints (Pint being the commonly used measurement for volume or capacity). The higher the capacity, the more water that the unit can extract in the same amount of time.

The selection of the size of dehumidifier is dependent on the following factors:

  • The size of the attic for which you need a dehumidifier
  • Relative structural dampness (unwanted moisture in the structure of the building)
  • The temperature of the surroundings

One thing that you must keep in your mind is that testing of dehumidifiers is done in ideal conditions so they may work slower than what is shown in advertisements.

The selection of dehumidifiers with the exact capacity as required will save you from spending extra money on a large capacity dehumidifier.

So, we would advise you to choose a dehumidifier having more capacity than is required.

b) Dampness Level in the room

The dampness level in an attic is also an important factor while choosing the dehumidifier.

To make things easier, we have shown the four main dampness levels and the size (pints per 24 hours) of the dehumidifier that will be compatible with each of these conditions.

Dampness Lvl

Capacity (Pints per 24 hrs)

Moderately Damp


Highly Damp




Extremely Wet


Thus before selection, one must also make sure to observe the dampness level.

c) Tank Size / Water Storage

If conditions inside the attic are extremely wet and you need to let the dehumidifier run for a longer period, then you must also consider the water removal from the dehumidifier.

Every dehumidifier comes with an internal water storage tank, but most of the designs have tanks with smaller daily capacity.

It means that you have to empty the tank once it gets filled.

If the tank size is much smaller, you may need to empty it two to three times a day.

To avoid this problem, we would recommend you to choose the unit having a continuous drain feature.

It will solve your worry to empty the tank, but for that, you will need to have access to floor-level water drain.

However, if you don’t have access to a floor-level water drain, you can still pump the water into the sink.

Best Dehumidifier for COPD

Most of the dehumidifier units come with an internal pump, but if your device doesn’t have the pump, you can buy and connect it with the dehumidifier unit.

d) Ease of Cleaning

As mentioned above, try to buy a dehumidifier having a continuous drain feature as it will solve the problem of emptying the tank containing the stagnant water.

If the water stays in the tank for a longer time, it may become the root cause of growing bacteria and viruses.

Moreover, if you don’t have access to a flow-level water drain, then you should take great care of emptying the tank.

Generally, choosing a unit that is easy to clean is the smarter choice. The selection of this type of unit will save both your time and effort.

e) Noise

You must also check the level of noise that a dehumidifier produces.

If one unit perfectly matches your requirements but is a nuisance, then you should start looking for another option.

Always pay attention to this factor before buying the product.

f) Other Factors

  • Dimensions: Before buying the dehumidifier, you need to keep into consideration the area where you intend to use it. Go for the unit which is not too bulky, easily movable and can efficiently work in that particular area.
  • Auto-regulation: Too high a humidity level in the room can lead to great discomfort for COPD suffers. Hence the dehumidifier needs to be able to keep the humidity stable at all times. If the device can automatically sense the humidity in the room and adjust its settings to maintain the level you desire, then that’s the product you might want.
  • Ease of Use: Some dehumidifiers become a headache for a busy person. We would recommend you to choose the one with continuous drainage function and is not noisy. Otherwise, you will have to empty the tank every time, and the noise can cause a disturbance in sleep at night.
