Compressor dehumidifier or dessicant dehumidifier? It may not quite be a rivalry on a par with Oasis and Blur or Johnson and Starmer, but if you want to dehumidify your home, you need to know the differences, so you can judge which type is likely to be best for you.
Dehumidifiers are a brilliant solution if you’re looking to remove moisture from the atmosphere in your home. Dehumidifiers should be perfect for year-round use – not just in the winter – if you live in surroundings that are prone to damp. That doesn’t mean you have to live in a property prone to moisture either because damp, fuggy bacteria-laden air can often be present in the least likely of scenarios.
Read our guide to thebest dehumidifierfor your home, and you should find something suitable for you. However, if you want some background buying info, the most important when it comes to dehumidifers is whether to opt for a dessicant or compressor groups; those that are designed around a compressor and refrigerant arrangement, not unlike a fridge, and those that make use of a desiccant – an absorbent material that sucks up moisture.
A dank atmosphere might be easier to notice if you live in a smaller property such as a flat, but high moisture levels can be present in any kind of property and in any kind of location, even if it’s well ventilated. Just having a bathroom being used regularly is enough to raise levels of moisture in your home, as is having damp towels or other items of soggy clothing hanging around. In fact, you can even use a dehumidifier to assist with drying clothing. It may not be as fast as thebest tumble dryer, but it is a handy bonus trick.
While the main objective of using a dehumidifier is to lower moisture levels, the way the unit gets the job done will vary slightly depending on the type. So, what are the differences between a compressor and desiccant dehumidifier, and which should you get? Read on to find out…

What is a compressor dehumidifier, AKA a refrigerant dehumidifier?
While the unwanted water can be stored and thrown away, or in some cases got rid of automatically via a pipe connected to a drainage source, the air passing out of the machine emerges warm and dry. Depending on the dehumidifier model you choose these units can be great at targeting specific problem damp areas, but they’re also great for pulling moisture out of entire rooms.

What is a desiccant dehumidifier?
The desiccant dehumidifier does the same job of removing moisture from the air in your rooms but in a different way. Rather than using a compressor and refrigerant arrangement, it sucks up moisture using absorbent material known as a dessicant.
Any damp air is again pulled into the machine and passes over the desiccant material. Warm air is then used to evaporate the water droplets collected within the desiccant, and dryer air is released back into the atmosphere.
Is a compressor or desiccant dehumidifier better?
This depends on just how much moisture you’re looking to remove. Compressor/refrigerant models are generally suited to more extreme damp problems and can remove larger amounts of moisture. Beefier units are frequently called in to tackle serious issues such as flood damage in homes because they’re so potent. They work to best effect in warmer climes. That’s not to say they’re useless in cold temperatures, but performance does drop off.
Compressor dehumidifiers work best at around 20ºC. Most homes are heated to at least this level, on average. However, if it’s cold out and you’re not running your heating due to the cost, or you want to dehumidify a room or out buildingwithoutheating, a compressor dehumidifier may not be ideal unless you live somewhere consistently warm – ie: not the UK or much of the USA.
If you’ve got slightly lower levels of damp in your home and simply want to take the edge off the moist air, a desiccant model will often fit the bill. Generally speaking, desiccant models can operate consistently at temperatures from 1ºC to 30ºC. They do use more energy than compressors, however.
There are other considerations to think about too, with noise being one of the big issues for anyone who needs to run a dehumidifier through the night. Refrigerant models with a compressor tend to be noisier than desiccant units, although this varies with the quality of the machine you’re buying. If you’re out and about then the noise probably won’t matter while the dehumidifier does its stuff. But, if you’re looking for peace and quiet come bedtime, be sure to check the decibel rating of your preferred machine.
What size dehumidifier should you should buy? There are plenty of bulky units – both refrigerant and desiccant – made to tackle larger scale damp and moisture problems. That’s fine if you’ve got room for one and don’t mind manhandling it around. However, if you’re looking for a model just to take that edge off the dampness in your home, you might be better off plumping for a smaller, portable unit. Some dehumidifiers are pretty compact, making them quick and easy to relocate if you need to focus the attention of your unit on another area in the home.
What else should I look for when buying a dehumidifier?
Naturally, official manufacturer’s figures will often paint a slightly rosier picture of just how much moisture a model can remove, so be prepared to shave a little off those stats when using a unit in real life surroundings. If you just want a basic dehumidifier to remove moisture without much in the way of frills that’s fine.
However, if you’re looking for a slightly smarter dehumidifier then it’s worth shelling out a little more for higher specification features. A good one to look out for is a humidistat, which is a feature that will make your dehumidifier automatically adapt to its surroundings and tweak its performance to match. Other options, such as multiple fan settings or a drying mode, are all down to what you want your unit to do.
Which brand of dehumidifier is best?
If you’re in the UK then one of the instantly recognisable dehumidifier brand names is Meaco. This company has been making them for years and they’ve got models to suit all kinds of requirements, from small compact units through to beefy, high-specification dehumidifiers that can take on higher levels of moisture and condensation.
You’re not just limited to Meaco though because the range of dehumidifiers on the market is reasonably sizeable and seems to be growing. Perhaps this is because more of us are living in smaller spaces, which can often be worse for trapping damp air. So, models from the likes of DeLonghi, Electriq and Ecoair are all worthy of inspection too.
