What does a Dehumidifier do?

It’s normal for us to not even think of the air because we spend so much time there that whatever the condition is, we become accustomed to and accept it as normal. It’s important to remember that the air contains water droplets which lead to humidity.

All air has a humidity level, and this humidity can be caused by numerous things such as slow drying clothes that are hung around the house with this problem worsened if it’s cold. Once humidity levels begin to rise this an obvious sign is often condensation forming on the windows.

The best dehumidifier can reduce humidity levels by sucking in the air from your home and removing the moisture. Once this process is complete, it then releases the treated air back into your environment. The moisture that’s removed from the air is collected into the dehumidifiers water tank.

What is relative humidity?

Relative humidity refers to the current amount of moisture that’s in the air compared the maximum moisture capacity. Relative humidity varies from standard humidity readings because it takes into account the changing factors such as the current temperature. When the temperature of the air is higher, it has a greater capacity to hold more moisture.

Condensation on your window is often the first sign of excess moisture because of this process. When warm air is flowing inside your home and hits a window, the surface of the window cools the air which lowers its relative humidity which reduces how much water it can hold. This forces it to cool, which then forms condensation.

The ideal humidity range is between 40-60%, but this is just a guide and will vary depending on your current climate and the time of year. However, this is a good guide range to stick between, and the best dehumidifiers will allow you to select your desired humidity setting so you can maintain this.

Do I Need a Dehumidifier?

Now just because you have damp or mould this doesn’t mean you need to suddenly go running to buy a dehumidifier and there are several other methods you can try to lower your humidity. Of course, a dehumidifier is a sure-fire way of successfully doing it.


Ventilation is a key component to lowering humidity levels, so make sure that you have enough airflow in your home. When you cook, ensure that you use an extractor as it’s common for many people to have one installed but never use it.

After your shower, you’ve probably noticed that your bathroom becomes steamy. When you shower, you should either leave your bathroom window open after for 15 minutes to disperse the moisture or turn on your bathroom fan, which does the same job but at a faster rate.

Clothes Drying Habits

Wet laundry is one of the main causes of excess moisture in the home, so it’s important that if you have the option, you should dry your clothes outside. This isn’t always an option, so if you have to dry them inside, make sure that you have the windows open as this will reduce the formation of moisture in your home.

If you can dry them outside, you should use a drying rack or clothesline. If you’re forced by circumstances to dry them inside, you should use a dehumidifier which will make them dry faster.

Tumble Dryer Configuration

We know how time-saving a tumble dryer can be, but you should check that the vent is installed correctly. If it’s installed incorrectly, it could mean that moisture isn’t being directed outside but is coming back into your home which contributes to excess moisture forming which leads to mould and condensation.

Showering habits

Your showering habits may be contributing greatly to your excess moisture problems, especially if you have a small living space, so you should take shorter length or colder showers. This is an alternative if you either don’t have a bathroom window or a bathroom extractor fan.

Check Roof

You should regularly check the health of your roof and drainage because you this could be the root cause of the issue so the problem could remain regardless of the changes you make in your home.  You should fix any existing leaky pipes, and if you have any exposed pipes, you should wrap them in insulating material which will prevent condensation from forming.

Obvious signs of a leak are wet spot on your walls or irregular water bill costs that you just can’t account for.

These are just a handful of tips that are low cost but just require your time, but if you find that your condensation and moisture problem needs more attention, then a dehumidifier is an ideal choice.

How to Choose a Dehumidifier

So if you’ve decided that buying a dehumidifier is the best choice to reduce or remove your mould, then you need to ensure that you pick the best model for your needs. There isn’t a universal number one choice because there are specialist models that are made for different types of scenarios and depending on the severity of your moisture levels.


Most dehumidifiers will be in the range of between £120-£250, and the price will largely be dependant on the number of litres that can be extracted every 24 hours which is referred to as the extraction rate.

The higher the extraction rate you need, the higher the price you’ll need to pay. The extraction rate you require will depend on the amount of damp you have or the number of room/size of your home.

Dehumidifiers that are best suited for medium-sized homes will require a budget of around £200, which will give you access to the best choices on the market. If you want the top-end models with the latest features, then this will be slightly above this number however this will include features such as digital control displays and energy-saving technology, so you end up saving money in the long run.

Just like any type of product, spending more doesn’t always mean that you’ll get a higher quality product. But we’ve created this guide to show you this in action.

Types of Dehumidifier

Dehumidifiers have been around for several years and have transformed. Due to the developments in the market, different types of dehumidifiers have their benefits and drawbacks.

Refrigerant dehumidifiers are the most common type of dehumidifier, mainly because they were designed first. They operate most effectively in warmer conditions but are also highly energy-efficient, so it won’t cause a huge spike in your electricity bills.

They are also fast at extracting moisture from the air, but they can also be louder than alternative types so are ideal if you aren’t worried about hearing the unit in action.

Desiccant dehumidifiers are the newer type of dehumidifier and can operate in cooler lower temperature conditions which makes them ideal in this country. They aren’t built using compressor or coil components which makes them lighter so you can easily move it around the home.

This type of dehumidifier also has a quieter operation which makes them ideal for home use, especially if you don’t want to hear the unit rumbling in the background. They do consume more energy compared to refrigerant options, but as the market continues to develop, we’re seeing more energy-efficient models created.


The capacity of a dehumidifier refers to the amount of moisture it can extract over 24 hours. It’s important to note that the capacity in the product specifications is based around having the unit in ideal conditions.

This spec is the easiest way to compare the extraction rate between models and the capacity you need will depend on how severe your moisture problem is. The extraction rate will also have a close link to the overall weight and size of your dehumidifier due to needing more physical power and size to extract more water.

Physical Size and Weight

Usually, your dehumidifier won’t just sit in the same place for its whole life, but you’ll move it around the home to where you need it the most. The best Dehumidifier can vary in weight from 5kg up to 15 kg so you should take this into account before you decide to buy.

It will also depend on the size of your home, so if you only want it for a small room, then a more compact model may be better suited. The effect of its size and weight can be negated by choosing a model that comes mounted on castor wheels or has a carry handle which will make it easier to move.

Off Timer

This is a handy feature that allows you to set the dehumidifier to turn off after a specific amount of time. This means that you can leave it unattended to run in the background without worrying about remembering to turn it off, which will lead to your saving energy as you won’t end up accidentally leaving it running.


In cold conditions, if the temperature falls too low, then the coils inside the dehumidifier can begin to freeze. If your dehumidifier has auto defroster, then it will use its power source to defrost to avoid damage before it continues to dehumidify your home.

Automatic Shut Off

Your dehumidifier will likely have a water tank inbuilt where the excess moisture is collected. When this tank becomes, full an automatic shut off feature means that the dehumidifier will automatically turn off and stop processing air when the tank becomes full. This will prevent the tank from overflowing, and once you empty the tank, it will continue to run.

Auto Reset

The auto-reset feature means that if you have a power cut when you regain power and turn the dehumidifier back on, it will remember its previous settings and continue where it left off. So if you have a power cut, then this is one less appliance in your home that you need to worry about.

Additional Filtration

A high-quality dehumidifier will often come with additional filter or ionisers that work to purify the air. A standard unit will remove moisture from the air, but if it has a purifying filter, this will remove other unwanted particles from the air such as bacteria and dust.

Automatic Humidity Monitoring

Most high-quality dehumidifiers continually monitor the current humidity levels to ensure that you remain in an optimal environment. Automatic humidity monitoring means that once it reaches its desired humidity level, it will switch off which save electricity. Once the humidity levels begin to get too high, the unit will then turn back on. This process means that you don’t need to micromanage your dehumidifier and you can leave it to operate independently.


There are several stands out brands within the dehumidifier industry that we’d recommend you stick to because these brands have not only been around for many years but have established themselves as the leaders due to creating the best dehumidifiers.

Not only are these products high quality, but they also have a wide range to suit all budgets leading to them having hundreds of reviews from users so you can make a more accurate buying decision.


A warranty is a period of time after purchase that you’re covered for in case your product develops a defect. Warranty lengths vary depending on the manufacturer, but it’s important to ensure that one is provided with your purchase because the best options are going to set you back a couple of hundred pounds so you should check what you’re entitled to.

Energy efficiency is the measure of how much energy an appliance requires in comparison to its output. In general, refrigerant models are more energy-efficient, making them cheaper to run, but they’re only suitable for warmer conditions.

Desiccant models require more energy but work faster, so need to be turned on for less time plus they can also operate at lower temperatures which makes them ideal for this climate. However, it’s important to understand that the high-quality models have energy-efficient settings which means you can lower the extraction speed, which lowers the energy consumption.

How to Use a Dehumidifier

There are several tip and tricks that will help you get the most out of dehumidifier which in the long run will save you money in energy costs and means you’ll need to replace your dehumidifier less frequently.

Read the User Manual

When you receive your dehumidifier, it’s important that you read the operating manual before you turn it on. There will usually be important information in the manufacturers manual that will allow you to get the most out of your unit.

Filter Cleaning

As the filter is used, dust and other particles may get trapped and clogged just like it does in a conventional vacuum cleaner. A dirty filter means it’s not as effective at removing impurities from the air so you should regularly clean it. Most filters can be cleaned using a vacuum or by wiping it down with a moist cloth.

Replace the Air Filter

Many dehumidifiers will come with an inbuilt air filter which removes impurities from the air such as dust and bacteria but also protects the internal components of the machine. Naturally, air doesn’t move through the dehumidifier smoothly, so if the filter isn’t cleaned, then it will make the dehumidifier work harder, which makes it less energy efficient.

You should refer to the manufacturers manual to understand how often the filter needs to be replaced.

Dehumidifier Placement

For dehumidifier to work best, they need to be placed in the ideal conditions, and the placement is very important. They need an unobstructed airflow to work most effectively, and there should be at least six inches between the unit and the wall, so the air intake and exhaust aren’t blocked.

Clean the Water Container Frequently

Regularly emptying your water tank will help to keep it clean but this won’t do the full job and won’t make it completely clean. This can lead to the build-up of bacteria or mould so you should regularly clean it with warm soapy water and make sure it fully dries before placing it back inside the dehumidifier.

The tank may look clean to the naked eye, but not all germs are visible so you should set aside regular time to clean the tank as it only takes a few minutes.
