What makes a Dehumidifier Large?

A dehumidifier is large due to its size, weight and larger water extraction capacity.

The best-sized dehumidifier depends on the area and environment it is used in. In a small space, a lower capacity is required. If you’re going to remove moisture from an entire house, you’ll want a larger capacity dehumidifier.

A larger dehumidifier does use more energy than a smaller capacity model, which can increase costs (even with energy efficiency features). However, if you need to remove moisture, mould, and reduce humidity levels for an entire home, then a large dehumidifier is an excellent choice.

Why Buy a Large Dehumidifier?

A large dehumidifier is perfect for extracting water and reducing mould in large spaces such as a home or unoccupied property.

The larger water extraction capacity allows larger dehumidifiers to remove moisture from a greater area. Unfortunately, this does mean more energy is needed than a smaller capacity dehumidifier to extract moisture from the air. Even with the energy efficiency features, it would cost more to run a larger capacity dehumidifier than a small model.

Unlike a smaller dehumidifier, a larger model requires a designated spot in the home. Usually, larger models take up a lot more space than small models, as they are less compact. So do take this into account when you’re looking for a large capacity dehumidifier.

If you do want to move a large dehumidifier around the home, they are less portable than smaller models but can come with casters (wheels) and handles. These features help to move the larger models around a home a lot easier, be careful as they are a lot heavier.

PROS:
  • Great for removing water in larger areas.
  • Extract more water than smaller capacity models.
  • Larger water tanks to hold extracted water.
CONS:
  • Less portable than smaller capacity models.
  • The larger capacity uses a lot more energy.
  • They cost more to run.

Reputed for being one of the best large dehumidifiers on the market, the unit’s easy to understand controls and ability to extract moisture in an efficient manner means that the Meaco 20L has been on the Which? Best Buy list for a number of years.

Being a refrigerant dehumidifier, it is more efficient at home temperatures, although it can still be used at lower temperatures should you need it.

A larger dehumidifier at 39x62x28cm and weighing 13.7kg, it is one of the larger dehumidifiers on the large dehumidifier list, although it does come with wheels for ease of transportation.

Despite its remarkable size, it is relatively quiet compared to other units of the same size, but it can sometimes reach 45dB when on full power, so bear that in mind if you have small children in the home.

With an A+ energy rating, it also happens to be one of the most efficient on the market, which is great if you need to get rid of the mould without spending big.

The unit’s easy to use controls, as already mentioned, are highly respected and lets you access a range of functions within seconds. An automatic timer also means that you can switch the unit off between one to 24 hours.

A continuous drainage feature also means that you don’t have to spend time replacing the trays.

The unit also comes with a HEPA filter, which means that it can help reduce allergens in the home, which is great for those that have asthma, although you will have to buy extra filters separately.

In all, the Meaco 20L is one of the finest dehumidifiers on the market and comes with a range of features. It should be near the top of any shopping list.

Perfect if you need to rid your home of large quantities of moisture, the Electriq CD20LE-V2 has been on the Which? Best Buy list since May 2017.

In a compressor model, the unit works better in warmer environments and can extract 20 litres of water every 24 hours at 30°C and 80% humidity, although it will be less efficient below 50°F (10°C).

Suitable for large homes, the unit comes with a three-litre tank, which means you don’t have to empty it frequently. Its continuous drainage feature is also very handy if you have a local low-level drain.

Using only 240 watts to operate, the model is highly efficient, and also comes with a humidistat, energy-efficient compressor and a frost watch, all of which help to reduce running costs.

The only aspect of the unit that is average is the noise that it produces, which sits at around 42dB, which is fair when you consider that the unit weighs 14kg and comes in at 42x64x29cm.

Thankfully, the unit also comes with wheels so that you can move it from room to room.

Including a laundry feature, if you need to dry extra loads, the Electriq CD20LE-V2 is a brilliant machine and one that comes with a range of features if you are looking for a dehumidifier the exceeds in versatility.

A member of the Which? Best Buy list since November 2017, the De’Longhi DDS25 Dehumidifier is a highly regarded dehumidifier and one that can get the job done easily and quickly.

Able to suck 25 litres from the air in a 24 hour period based on 30°C and 80% humidity, the unit can still work well at temperatures as low as 15°C.

Certainly a monster of the domestic league, the DDS25 is one of the largest on the market.

Highly energy-efficient and featuring a range of functions to improve said efficiency, it is certainly a model for those wanting to maintain reasonable energy bills.

Weighing 15kg, it is also one of the heaviest on the market but does come with both wheels and a handle.

A relatively noisy machine, although not able to exceed 50dB, if you’re looking for a quieter model, this one might not be the one for you. That said, if your home is particularly large, you might be able to get away with it.

The DDS25 also comes with anti-bacterial filters, which is great if you’re looking for a machine that can also clean your air while it removes moisture.

Coming with a four-litre tank, it is not a machine that requires constant emptying, although there is also a continuous drainage feature, you will need to buy a separate drainage kit to use it.

An excellent large dehumidifier by anyone’s standards, the De’Longhi DDS25 is easy to use, efficient and very good at removing water quickly, making it one of the best machines on this list.

The final one on our list of the five best De’Longhi dehumidifiers is the most capable – regarding capacity – of the lot. It’s also the most expensive, but when you have a look at the price difference between this one – at the top of the list – and the least expensive one of our five, the gap isn’t that large.

PROS
  • 4.5-litre tank
  • 20-litre extraction capacity
  • permanent drain facility
CONS
  • heavy
  • loud
  • uses lots of energy

For this reason, we’re not sure that price will be a clincher when looking at a De’Longhi humidifier, as many other factors come into play to affect your decision.

So far, we have covered a good range of De’Longhi models, most of which have a 2-litre capacity water tank (one with 3-litres) and some with a permanent drain kit, so you don’t have to keep emptying them. This model, the DDS20, features a massive 4.5-litre tank, and that comes in a package that measures just 28x35x49 cm, so not considerably larger than any of the others. There is also the option of the continuous hose attachment, for which you need a handy internal drain.

If you want to use it with the reservoir, you won’t need to empty it that often. The DDS20 can remove as much as 20-litres per day, which is the most significant capacity on our list.

To remove that much moisture per day the DDS20 dehumidifier needs a massive 450 watts of power. We recommend considering this when purchasing this model, as you are going to pay more for it to run on a regular basis. However, remember this dehumidifier is suitable for larger homes (5+ bedrooms) rather than small ones.

The DDS20 measures 15 kg, but this model is not meant to be portable, so this shouldn’t be a problem if you buy it for the purpose it is intended. It does not have an ionizer – a couple of the above models do so if that is important to you check them out – and it comes with the usual 2-year De’Longhi warranty.

There is a lot to recommend this particular dehumidifier for family use. Although there is no dedicated clothes drying system it does have an anti-bacterial filter so is great for asthmatics. However, here is the downside, and it’s one you may have guessed. This is a 450-watt machine, and it may come as no surprise that noise output is no less than 50 dB.

Bearing in mind what we said before – and that the previous loudest was 40 dB – this one is quite clearly going to be a lot louder, so you might want to bear that in mind. As the model is so loud, the DDS20 is not suitable for use in a small flat or house. If you want a machine for a bigger house and have a permanent position where the sound will not affect anyone, then there is no reason this cannot be the best choice.

The DDS20 De’Longhi dehumidifier is an excellent choice for those with larger houses, and a need to remove a lot of moisture from the air efficiently. Just be aware that this model is not designed to be used to dehumidify a flat or small home.

A much quieter model, the DNC65 is one of De’Longhi’s most silent, which is great if you need a machine that operates on low volume.

Able to work at 34dB, the model is also fairly compact at 17x29x47cm and features a two-litre tank, which means that you’ll need to empty the tank every few hours.

Weighing only 6.5kg, the machine is easy to transport and can happily remove moisture in a room of 55 cubic meters, largely thanks to the three different power levels that you can choose from.

With an eight hour shut off feature, you can also help save on energy bills while utilising its clothes drying and ioniser settings, both of which serve as great bonuses.

For those looking for a middle of the large road dehumidifier, then you should pay particular attention to this unit.

Frequently Asked Questions

How much does a large dehumidifier cost to run?

The average dehumidifier generally will cost around 3 to 4 pence per hour to run if it’s on continuously. A larger dehumidifier will likely cost a little more, we’d estimate 5 pence per hour, but this will depend on your space and electricity provider.

For more information read our ‘How Much Does it Cost to Run a Dehumidifier?’ guide.

How long should my large dehumidifier be switched on for?

There’s no need to run a large dehumidifier 24 hours a day. A rule of thumb would be to run it when your humidity levels are around 50% or higher. A humidity level of 30% – 50% will be the right level for most homes.
