What is a Desiccant Dehumidifier?

There are two primary types of dehumidifiers on the domestic market, compressor (refrigerant) or desiccant dehumidifiers.

A desiccant dehumidifier works by drawing air through the duct, where it’s passed through a rotating wheel made of desiccant material. The desiccant material is a drying agent that absorbs the moisture from the air and removes the humidity.

The dehumidifier needs to continuously heat the desiccant material, using an electrical heating element to dry out the wheel and keep absorbing the air’s moisture. This means that desiccant dehumidifiers will use more electricity than refrigerant dehumidifiers.

A desiccant dehumidifier does have one advantage over refrigerant models. Due to how the dehumidifier works, it’s excellent at extracting water in colder temperatures; this is because of the heating element which dries out the absorbing material, even in chillier environments.

Therefore a desiccant dehumidifier is a perfect choice if you want to remove moisture from a garage, caravan, or unheated room in your home.

Why Buy a Desiccant Dehumidifier?

The desiccant dehumidifier is a perfect choice for those who want to remove moisture from an unheated house or room.

The reason the desiccant models have an advantage in colder temperatures is due to how refrigerant models work. A refrigerant dehumidifier works most efficiently when the unit’s temperature is colder than the air around it. As soon as the environment drops below 50°F or 10oc, a refrigerant dehumidifier will work less efficiently, as ice begins to form within the unit. The refrigerant model needs to spend time heating up and removing the ice before continuing.

The desiccant dehumidifier models use absorbing material to extract water from the air and use a heating element to dry out the material. This means that they don’t need to stop and heat up to remove ice from inside the unit; it is already a continuous process.

The use of the heating element makes the desiccant dehumidifier ideal for extracting water from unheated environments, such as:

  • Garages
  • Unheated rooms in a house or flat
  • Unoccupied properties
  • Basements
  • Caravans

Similarly to the Meaco 20L, the DD8L is viewed by many as one of the best dehumidifiers on the market, excelling in pretty much every area. Being that it is a desiccant dehumidifier and one of the best-reviewed on the internet, it can operate in colder conditions and average room temperatures.

This means that if you need to extract moisture from your garage or your basement, you’ll be able to do so with the DD8L, although it shouldn’t be used in freezing environments. A refined machine, the DD8L, is energy efficient and holds a class A rating, which means you can get the results you need without having to worry about the bills. A smaller dehumidifier, even for the domestic range, at 36x20x55cm and weighing 8kg, the unit is easy to transport and has a handle found on the top.

Easy to use, the unit is complete with the unique Meaco control logic, which allows you to maintain a humidity level chosen by you. What’s more, you can set the unit to check the humidity levels every 30 minutes. All of this can be achieved by using simple and highly accessible digital display and controls.

The DD8L is often the dehumidifier of choice for those who have family members who suffer from asthma. It comes with an ioniser and antibacterial filters, great for keeping the air clean and reducing irritants.

Bearing a middle ground water tank at three litres, you might want to utilise the continuous drain facility to avoid emptying it every few hours. You’ll need to ensure that you have a hose that leads to a low-level drain outlet.

It goes without saying that if you’re looking for a smaller energy-efficient desiccant dehumidifier for your home, then the Meaco DD8L Zambezi should be high up on your list.

The Meaco Junior DD8L is one of the smallest desiccant dehumidifiers on the market and is excellent in situations where you need a small and transportable dehumidifier for your humidity needs. Able to operate in cooler temperatures while being incredibly compact means that you’re ready to use it in mobile homes, outhouses, garages, and conservatories without few concerns.

Weighing a mere 6.2kg and owning a dimension of 18x35x50cm, this is often the desiccant dehumidifier of choice for those who have only limited living space. The only let down of the Junior DD8L concerns energy efficiency, as it isn’t the greatest model in this area. If you’re concerned about your bills, the Meaco 20L Low Energy Dehumidifier is probably a better option.

It’s also worth noting that it isn’t the quietest model on the market, but this depends on where you plan to use it on your property. Being so compact, the model only holds up to 2 litres of water, so it’s probably best to use the continuous drain feature if you can. It’s also worth noting that the until also comes with a mounted wall bracket if you are tight on space. The Junior DD8L also comes with a great control unit, which you can also set to maintain your room’s moisture level.

If you’re searching for a compact desiccant dehumidifier, then the Junior DD8L should be a strong contender, especially if you plan on using it in a colder room.

Able to extract 10 litres of water in a 24 period based on a room with 60% relative humidity at 20ºC, the DD3 is great if you need to remove large quantities of moisture in a short period of time.

That being said, the DD3 does happen to be one of the noisier machines on the list, so bear that in mind if you plan to operate it at night or you have small children at home.

Fitted with a 3.5-liter water tank, the unit also comes with a continuous drain feature, which is great if you don’t plan to be at home all day or don’t want to be emptying the tank every few hours.

Despite its immense capabilities, it weighs a mere 8.4kg and is quite compact at 18x41x55cm, which makes it great for moving around the home, although it doesn’t come with wheels like some of the other models.

Neither is it the cheapest to run on the list, using 670 watts, making it one of the list’s costlier dehumidifiers. Of course, you could search for a cheaper to run unit, but you could be sacrificing important features.

These include the controls, which are easiest to navigate, and you can set the machine to turn off after two, four, or eight hours, which helps keep the price down.

As an added bonus, the unit also comes with a laundry feature.

Indeed, a model that is able to absorb vast quantities of moisture in both warm and colder temperatures, the EcoAir DD3 is a dream to use and should be one to think about if you’re after a desiccant dehumidifier that comes complete with special features.

It’s taken a while, but De’Longhi has been working on its dehumidifiers’ noisiness for many years, and it seems that it has finally succeeded with the DNC65.

A highly efficient model, if you’re searching for a dehumidifier that is as quiet as it is efficient, then the DNC65 could be the model for you. With an output of 34dB, its levels are impressive for a machine as sizeable as this, although this is largely due to the fact that it has no compressor.

That said, it is also rather compact and measures in at 17x29x47cm, making it somewhat smaller than the DEX12. With a two-litre tank, however, it will need emptying reasonably regularly. Weighing just 6.5kg, the machine is straightforward to move around and can easily extract moisture from a room of 55 cubic meters.

There’s also a very convenient shut-off feature that will turn the machine off after 8 hours, which is great for those that want to keep it running for some time while they are away. Able to operate on three different levels for efficiency purposes, the unit also comes with clothes drying feature and a separate ioniser to tackle pollutants and bacteria; great if you are looking for a cleaner home.

In all, this is a highly compact and efficient dehumidifier that is perfect for those searching for a quieter model.

A dehumidifier with a good reputation for extraction in large rooms, the EcoAir DD1 Classic MK5 comes with electronic controls valued for ease of use.

As already mentioned, the EcoAir excels at removing moisture from the air and can tackle seven litres a day, which is good for this size model, although it isn’t the most significant capacity on this list.

Ideal for small flats and apartments, the unit has a two-litre tank smaller than other EcoAir models. If you’re not too keen on removing water all day, there’s also a continuous drainage feature if you can access a low-level drain.

For those interested in energy efficiency, the model uses 580 watts while working, which is slightly less than the EcoAir DD3, but less than other units on the market. Weighing only 6.2kg, however, the EcoAir DD1 is very compact at 52x39x27cm, which means it’s great for small rooms and apartments and comes with castors and a handle.

If you’re looking for a quieter unit, the unit works at 34dB, which means that it is one of the quietest list. The EcoAir DD1 comes with various features, including an auto-setting function so it can maintain your chosen humidity level and an ioniser.

The electronic controls also make the unit easy to use and navigate, and it also comes with a laundry mode, which can be very handy if your machine is currently working on a heavy load.

Frequently Asked Questions

What size desiccant dehumidifier should I get?

You must choose a model based on the size of the room, but there are also other things to consider, such as the conditions of your room. Ask yourself “How damp is my space?”

Stick with the capacity that matches your space. If you have a lower level of humidity, then choose a smaller unit. If it’s a large and damp space then you should go for a larger capacity unit.

For more information read our ‘What to Consider When Buying Dehumidifiers’ guide.

How long do desiccant dehumidifiers last?

A desiccant dehumidifier can last for 3-5 years if the unit is looked after. A desiccant dehumidifier has a considerably longer lifespan than a refrigerant dehumidifier because desiccant units are a lot less complex. The only major replacement part for a desiccant dehumidifier is the desiccant material, which absorbs the moisture sucked into the unit.

When should you use a desiccant dehumidifier?

A desiccant dehumidifier is excellent at attracting moisture in cold environments, and it more economical is colder temperatures. Therefore, a desiccant unit is a perfect choice if you want to remove moisture from a garage, caravan, or unheated room in your home.

For more information read our ‘How to Use a Dehumidifier’ guide.

How much do desiccant dehumidifiers cost to run?

Overall, it is thought that the running cost of a typical dehumidifier, depending on the humidity and the size of the area, would be around £10 to £20 per month.

The cost of a dehumidifier depends on multiple factors, including the dehumidifier’s energy rating, the cost of your electricity, and how long a unit is left on.
