Dehumidifier Buying Guide

Do you have a musty odour in your house for seemingly no reason? Is mould growing in your shower out of nowhere? Are their water stains on your ceiling or walls? If the answer to these questions is yes, you need a dehumidifier.

Many homes in the UK have the problem of excessive moisture. Presence of excess moisture in your home typically leads to damp walls, condensation and unsightly mould. If someone has allergies, excessive moisture will make it worse. If you do not take steps to get rid of the excessive moisture, you will not only have an unpleasant odour in your home but it will also create future problems for your floor, ceiling and walls as well as electronics.

Key Takeaways

  • Excessive moisture in your home can lead to various problems, including mould growth, structural damage, and health issues.
  • A dehumidifier is an appliance that helps maintain comfortable relative humidity levels by removing excess moisture from the air.
  • When choosing a dehumidifier, consider factors like capacity, air flow rate, energy efficiency, dimensions, warranty, noise, auto shut-off, portability, timer, and additional features based on your specific needs.

What is a Dehumidifier?

In simple terms, a dehumidifier is as an appliance that gets rid of excess moisture from the air in an enclosed space. The recommended range for relative humidity is 40 to 60% to remain comfortable. If the air holds more moisture, it might lead to growth of mould or formation of condensation on windows, walls or ceilings. A good dehumidifier is capable of maintaining comfortable relative humidity levels.

How Does a Dehumidifier Work?

Though there are many different types of dehumidifiers, the basic working principle remains the same. All the dehumidifiers work by pulling in moisture laden air from the surrounding environment. This excessive moisture is removed from the air through different processes and the drier air is then pushed back into the room.

DehumidifierThere are two basic types of dehumidifiers known as desiccant humidifiers and refrigerant dehumidifiers. Both these are equally effective but are ideal for use in different conditions.

Compressor or refrigerant dehumidifiers work by pulling in damp air. This damp air is then passed over a cold surface which leads to condensation of water in the air. This water drips into the water collection tank from where it can be drained out. In these models, a compressor is used to cool coils. These models are more energy-efficient as compared to desiccant ones but these are considered ideal for use only in warmer rooms.

In case of desiccant humidifiers, damp air passed over a material (desiccant) that absorbs moisture. There is a heater inside the unit which raises the temperature and the water absorbed in the desiccant is then collected in the enclosed water tank from where it can be drained out. These humidifiers are more effective in colder temperatures where the temperature is less than 15 degrees C.

Simply put, a desiccant dehumidifier is right for an unheated conservatory or garage whereas you should use a refrigerant dehumidifier in heated rooms.

What Are the Benefits of a Dehumidifier?

Damp air containing excessive moisture in an enclosed space not only makes the space uncomfortable but also poses some other dangers. It can lead to growth of mould in your home and when not kept in control, it might also cause structural damage. Here are a few reasons for you to invest in a dehumidifier today.

1. Get Rid of Allergens

Excessive humidity in the air has the potential to increase the dust mites and other allergens that can worsen the symptoms of people who already suffer from breathing issues. If anyone in your home is having breathing trouble, you need to invest in a whole house dehumidifier today.

2. Get Rid of Pests

Pest infestation is typically caused by the presence of easily available food and water in a home. Excessive moisture leads to condensation and this condensation offers an easy source of water for pests and other small insects. A dehumidifier will get rid of this excessive moisture and help in eliminating pest infestation.

3. Prevent Rusting

Dehumidifier with Touch PanelPresence of excess moisture in the air might cause all things metal in your house to rust. If you have a lot of wood furniture, it might also cause the wood to warp.

4. Stop Peeling Paint

If the paint in your house is peeling off or the wallpaper is coming off, it might be due to damp air in the house. A whole house dehumidifier can help in keeping the walls dry.

5. Save Your Electronics

Some components in common electrical appliances are susceptible to excessive moisture in the air. It is especially true of entertainment systems and computers. If you have lost some electronics for seemingly no reason, it could be due to damp air. A dehumidifier can help in preserving your electronics.

6. Get Rid of Smell and Mould

Excessive dampness causes musty smells. If you can smell musty odour coming from all parts of your home, it could be due to damp air. Excessive moisture in the air can also accelerate the growth of mould in your home. If you are witnessing a lot of mould growth and there is always a musty smell coming from your home, you should immediately get a dehumidifier. It will help in getting rid of the musty smell and also impede the growth of mould in your home.

7. Healthier Family

A dehumidifier will keep you and others in your home comfortable. In addition to humans, excessive humidity also has an adverse effect on animals. If you have pets are showing erratic behaviour, it could be due to excessive humidity. A dehumidifier will keep your pet happy.

Features to Look for in a Dehumidifier

There is a huge range of dehumidifiers available in the market at a variety of price points. You can buy dehumidifiers ranging from £40 to more than £400. Generally, the price of dehumidifier goes up with the capacity and extra features. Here are some of the important factors you should consider in order to make the right choice.


Capacity of a dehumidifier refers to the litres of water it can extract from the air in 24 hours. It doesn’t refer to its physical size or capacity of the water tank. If you want a dehumidifier for your whole house, choose a model with a bigger capacity.

To give you an idea of the capacity, a 6.5 L capacity model is capable of making a space of 45 square meter comfortable when air is moderately damp. Similarly, an 18 L capacity model is right for area of around 225 square meter.

An important thing you need to keep in mind is that the performance of two different models with same capacity could vary significantly depending on their type, environmental conditions and other things. Therefore, it is better to check individual reviews.

Air Flow Rate

The air flow rate of a dehumidifier also refers to its capacity and the time it takes to lower the humidity levels. Ideally, you should refer to the overall capacity of the dehumidifier.

Energy Efficiency

Dehumidifiers generally do not consume a lot of energy to operate. Refrigerant models tend to be more energy-efficient, especially when used in warm environments but as the temperature goes down, these become less energy-efficient. Desiccant models typically use more energy but also work at a faster rate and work more efficiently in cooler temperatures. Some models also come with multiple settings allow you to reduce the energy consumption but it affects the moisture extraction rate.


Dehumidifiers are generally compact in size, especially the small ones. You can easily place one in a corner. A bigger capacity dehumidifier will naturally have a bigger size.


As far as the size is concerned, you should worry about is the capacity of the model and not the size of the appliance or size of the water tank as most models meant for home use are compact in size.


Needless to say, you would want to buy a model that comes with at least a few years of warranty. These appliances are simple in design and keep working without any issues but it’s imperative to make sure that you can get free repair or replacement in case the unit stops working within its warranty period.


Dehumidifier UnitGenerally, dehumidifiers are not noisy and produce a slight hum when running. You do not need to worry about noise levels in most modern models.

Auto Shut Off

It refers to the feature where the unit shuts off automatically when the water tank gets full and you do not have to monitor it continuously.


Portability is essential if you want to move the dehumidifier from one room to another. These models typically weigh less and are smaller in size, and many models also comes with a carrying handle or rolling casters.


Some models also have a timer function that allow you to run the dehumidifier for a set amount of time ranging from 2 hours to 4 hours or more.

Other Features

In addition to the above, some other features also make sense in certain situations.

Some models have an auto restart function that automatically restarts the unit after a power failure. You do not need to re-enter the settings and the unit keeps operating with the previously selected settings. Some models also provide complete control with self-diagnosis indicators and allow you to set the humidity levels. The unit will automatically start once the humidity levels exceed the set levels and shut off automatically once the humidity levels have been brought under control.

These units typically also allow continuous operation. These come with a hose that allows continuous drainage without the need to empty the tank regularly.
