How Does a Dehumidifier Work?

Now you know what a dehumidifier is, but how exactly does it work? In this section, we will take a look at how a dehumidifier works so that you can know as much as possible about the appliance before purchasing one.

A dehumidifier works by taking in warm air currents from within your home via a fan. This air then enters refrigerated coils within the machine and all of the condensation that is present remains within the machine.

As the condensation collects within the machine, it falls into a storage tank. The air that is released back into your home is cooler and drier.

Types of Dehumidifier

There are several different types of dehumidifier. Below, we take a look at the advantages and disadvantages of each type:

Desiccant Dehumidifier

Desiccant dehumidifiers tend to be quite light, small and quiet. These machines work well in warm conditions and less well in lower temperatures.

Desiccant dehumidifier

These machines use a desiccant material that absorbs the moisture in the air in a similar way to silica gel.

The air is drawn into the machine via a fan and passed through a slowly rotating wheel filled with the desiccant material which dries the air. These machines tend to be very durable and usually last longer than a compressor dehumidifier.

Compressor Dehumidifier

A compressor dehumidifier is similar to a fridge. It draws in the air from the room, and this passes over a filter and then over cold coils. As the air passes over the coils, it condenses and drips into the bucket at the bottom.

Compressor dehumidifier

The air is then reheated back to room temperature and pumped back out into the room. These dehumidifiers work well in warm conditions but are less effective in cooler conditions.

What to Consider Before Buying a Dehumidifier

There are a few things that you may want to consider when choosing a dehumidifier to buy for your home. Below is a list of the main things that you should think about before choosing a model to buy:

Cost

Some dehumidifiers are much more expensive than others. It’s a good idea for you to have a budget in mind before you start searching for a dehumidifier so that you can narrow down your search.

The cost of the machine may also determine which type of machine you should be searching for as some styles will cost more than others.

Size

If you are limited on space in your home, you may want to search for a small or compact dehumidifier. On the other hand, if you’re planning on buying a dehumidifier that removes humidity in the entire home, then you may want to opt for a bigger machine that can handle what you need.

Noise Levels

Some dehumidifiers can be quite loud. With this in mind, if you are interested in a quieter machine, then you should look for quiet humidifiers.

If you are planning on putting your dehumidifier in a room where you may be watching TV, then it would probably be a good idea to opt for a quiet machine so that you can still hear the TV when the machine is on.

Digital Controls

Some dehumidifiers have digital controls and screens that allow you to see how much humidity is in the air at any one time. If these features are important to you, then you should search for machines that come with these features included.

Although they tend to cost more, these machines can provide you with some interesting information about the air in your home.

FAQs

What size dehumidifier should I get?

This will depend on the size of the area you are looking for it to work on and the humidity levels within that space. Bigger machines tend to cope with much larger areas and higher levels of moisture in the air.

If you are only planning on using the machine in a small room, you can opt for a small machine.

How much does it cost to run a dehumidifier?

The cost to run a dehumidifier will depend on the power rating of the machine and your energy tariff. Below is an outline of the average costs to run a dehumidifier:

  • 250W - £0.04 per hour, £0.46 per day, £3.24 per week
  • 500W - £0.08 per hour, £0.92 per day, £6.47 per week
  • 750W - £0.12 per hour, £1.39 per day, £9.71 per week

What does a dehumidifier do?

A dehumidifier is a machine that removes water from the air in your home until the humidity is reduced to the level that you choose. The dehumidifier will keep the humidity levels at your chosen level for as long as the machine is left on.

What is the ideal humidity level within a home?

Relative humidity of 50% is a comfortable level for the home. This level will protect you and your belongings and will prevent mould growth.

There is no need to reduce the humidity levels below around 45% as this will only cost more money in power and won’t serve any extra purpose.

Can I use the water that is collected within the dehumidifier?

The water that collects in the bottom of your machine can be used to water plants or could be used in your iron. However, you should avoid drinking the water as it may contain traces of substances that are unsuitable for human or animal consumption.
