Planning on moving the dehumidifier around the house? You&#;ll need to know which weighs less, a desiccant or compressor dehumidifier.
For more information, please visit our website.
Our general advice is that you should leave the dehumidifier in one place. As long as the internal doors are open, the moisture in the house will migrate towards the dehumidifier until it is close enough for the dehumidifier fan to pull it in.
However, there may be times when you want to move the dehumidifier around. For example, you might have built-in wardrobes in a bedroom that are prone to mould growth. You might have the dehumidifier upstairs on the landing but need to move it downstairs to dry the washing, or you might like to move it into a conservatory now and again or use it to dry out a poorly ventilated bathroom.
Compressors add about 6 kilograms to the weight of a dehumidifier, so carrying a desiccant dehumidifier around is a lot easier than carrying a compressor dehumidifier around. However, most compressor dehumidifiers come with castors, making them more portable.
Carrying your dehumidifier &#; the winner is desiccant.
Energy Consumption &#; how much does a dehumidifier cost to run?
Customers are understandably interested in how much it costs to run a dehumidifier. Compressor dehumidifiers are in general cheaper to run. However, a desiccant releases its extra energy as heat. So there will be a cost to run your dehumidifier, but you are getting heat back into your home, meaning you can reduce your central heating accordingly. And that has a positive knock-on effect on your bills. You have to decide if you want or need this additional warmth or if you just want the cheapest dehumidifier to run.
For example, in our compressor range, we have the Meaco Low Energy 12L Dehumidifier, running at just 4p / kWh as well as our MeacoDry ABC 12L, running at just 4p / hour based on 24.50p / kWh. That means, you can have the dehumidifier on 24 hours a day, maintaining your home humidity levels for just 96p per day.
So, for low energy and low cost operation &#; the winner is compressor dehumidifiers.
The good thing is, whichever dehumidifier you choose, a compressor or a desiccant, the dehumidifier will be removing cold, damp air from your home, meaning you don&#;t have to put your heating on as high &#; saving you money on your energy bills!
Noise levels &#; how much noise does a dehumidifier make?
This is an area where dehumidifiers have changed a lot over the past 5-10 years. It used to be the case that a desiccant dehumidifier on low fan speed was your quietest option, but a few years ago the MeacoDry ABC Range changed all of that with 10 and 12l models at just 36dB (close to the sound of a whisper). And then, we changed it again with the new Arete® One 10 and 12L compressor dehumidifiers which are even quieter at 35dB. So you can now buy a dehumidifier that is the quietest and cheapest to run.
For quiet operation, the winner is Meaco ABC 10L and 12L and MeacoDry Arete® One 10 and 12L Dehumidifier and Air Purifier. These dehumidifiers are all a whisper-quiet 35/36dB.
When choosing the right dehumidifier for you, confusion might arise from deciding between the two different types of dehumidifiers: compressor and desiccant. Whilst both fulfill the same purpose by extracting moisture from the air, they achieve this via different methods.

Compressor dehumidifiers use a fan to draw in air and run it over a cold coil (much like a refrigerator) so that the water condenses and is collected by the water tank.
A desiccant dehumidifier draws air into the machine before passing it over a desiccant chemical to absorb the moisture from the air.
For any application where the ambient room temperature is likely to fall below 15 degrees Celsius, a desiccant dehumidifier is recommended. As the room temperature falls, the compressor dehumidifier will become less effective. Whilst a desiccant dehumidifier will remain consistent regardless of temperature, compressor models may be the better choice for warmer spaces.
However, temperature is not the only determining factor. Compressor dehumidifiers are very effective at maintaining the recommended household atmosphere between 45-50%RH but if you want to manage your home at a lower humidity level, then a desiccant dehumidifier is likely to be the better option.
The energy consumption also varies between the two types of dehumidifiers; in general, desiccant dehumidifiers have a higher energy consumption. Our smaller desiccant models have a power consumption of approximately 250-550W compared to 210W from our similarly sized compressor models. However, as desiccant models are usually more powerful, they don&#;t need to be active for as long. For example, our desiccant models take 2-4 hours to dry an 8kg load of laundry whereas a compressor model will likely take 4-6 hours to dry the same load. In addition to this, as desiccant dehumidifiers emit warmer air (approx. 3-5 degrees Celsius warmer than the ambient air), you are likely to be using less energy on heating for your home. Therefore, whilst a compressor model theoretically has a lower cost operation, they are likely to cost a similar amount to run, with the desiccant possibly even being slightly cheaper if you plan on using your dehumidifier for laundry and heating purposes.
Quick Comparisons
Noise level
- Desiccant dehumidifiers are quieter than compressor dehumidifiers
Ambient Temperature
- Desiccant dehumidifiers work well in ambient temperature range between 1 to 40 degrees Celsius. Compressor dehumidifiers only work well between 16 to 40 degree Celsius.
Weight
- Desiccant dehumidifiers are much lighter. in weight For example a 7L per day desiccant dehumidifier is equivalent to a 10L per day compressor dehumidifier but the weight is 6 Kg and 11 Kg.
Power Consumption
- Generally desiccant type will use consume slightly higher energy cost compared to compressor type. However a desiccant dehumidifier will generally extract moisture at a faster speed than a compressor, therefore it is debatable as to whether a desiccant dehumidifier is more expensive to run. See next section Turbo.
Turbo
- Most desiccant dehumidifiers come with a turbo function where it literally doubles up its power when you need to do a fast extraction of moisture, for example there has been a flood, or you want to dry your laundry with the dehumidifier. This turbo function is designed to be used on a need to basis rather than as a normal basis. Compressor dehumidifiers do not have a turbo option. Generally the highest power consumption is being compared between one dehumidifier to another in the case of desiccant dehumidifiers, comparison is made between its Turbo mode against a normal mode of a compressor dehumidifier.
