Your Guide To The Different Types Of Dehumidifier
Not every unit is the same. In fact, how they operate and the environments which they are suited for can vary hugely. So, before you read our reviews we recommend checking out the handy guide below so you can find out what kind might be suitable for you and where in the home they can be used.
This is, by far, the most common type of dehumidifier. Typically shaped like a medium sized, white box that is plugged into a socket. In its simplest form, it works by drawing in damp air, removing virtually all of the water content (this is called condensate) and then sends out the air again, which is now dry.
How they work:
Inside a refrigerant dehumidifier is a fan which draws in the damp air and passes it over refrigerated bars/plates (which are sometimes filled with refrigerant). When the damp air passes over the bars the water it contains condenses and drips off into a collection bucket. The air then continues its journey over some warm bars before exiting the machine and is sent back into the room. This is why you can often notice that, particularly in smaller rooms, using this type of dehumidifier will often warm the room as well as reduce the humidity. As with most units these are usually controlled by a humidistat and/or a thermostat and will dictate when the unit should be operating.
The good news is there are a huge array of refrigerant dehumidifiers available to choose from, allowing you to find one to meet your exact needs. They range from the ever popular and powerful Ebac 2650e to the, much smaller, Meaco 10L.
- Typically these types of unit will require you to empty a container of water which fills over time, although some units will have a hose which can be fed directly into a sink or drain.
- They are very effective to use in small to good-medium sized rooms in your home and can even warm the air a little. (We use ours to very effectively remove damp and condensation in our bathroom).
- They are based on a tried and tested technology which is very efficient.
- They typically cost upwards of £100, but are considered the most cost effective to run and are very efficient.
- They can be quite heavy because of the compressor unit contained within the machine.
- These can occasionally be a little noisy. So, be sure to check the noise rating before you buy. Particularly if it is going to be used in a room you spend a lot of time in.
- They are not very efficient in lower temperatures and are more ideally suited for use within the home opposed to, say, a shed or stand alone garage where the temperature can plummet.
Also powered by the mains these appear virtually identical to any compressor dehumidifier. However, they do have several advantages that allow them to be used in places where a refrigerant dehumidifier may run into trouble. But, before we look at the key points, let’s first take a look at how this type of dehumidifier works.
How they work:
Just like a refrigerant dehumidifier, a desiccant dehumidifier works by drawing in humid air. Once the humid air is inside the machine, however, the process of removing the water is very different. The air is passed over a desiccant material which is located on multiple layers of the machines filter, this absorbs the moisture content before passing the dryer air back into the room.Some units will also slightly warm the air before passing it out. The heat used to dry the desiccant material when it is saturated is mixed with the air exiting the machine.
If you’re looking for a desiccant dehumidifier you would be hard pressed to miss EcoAir. They produce some of the most popular dehumidifiers available including the EcoAir DD128 and EcoAir DD122fw MK5.
- Desiccant dehumidifiers are typically very quiet because they do not contain a compressor pump and use evaporative coolers. Making them ideal for use in your bedroom or living room.
- Some units feature the option for ‘continuous drainage’ (some even use condesate pumps which actively push the water out of the machine) meaning you will not need to empty a container of collected water. A hose/pipe is simply position in a sink or drain.
- They can operate down to very low temperatures and still remain effective.
- The filters can often contain an anti-bacterial compound to remove dirt and bacteria from the air.
- They are typically much lighter than their refrigerant counterparts.
- They can be more expensive to run than a refrigerant dehumidifier.
These are becoming increasingly popular because of their quiet operation and effective performance – you can read our desiccant dehumidifier reviews using the link below.
Non-electrical desiccant dehumidifiers
As the name suggests desiccant dehumidifiers of this type do no need a power source to operate. Instead they typically consist of a small bag or container which, overtime, absorbs moisture from the surrounding environment. The container/bag typically contains small crystals or gel, it is these compounds which attract and hold the excess water.
How they work:
The crystals/gel mentioned above are typically composed of a hygroscopic material. This is a substance which can attract and contain water from the surrounding environment. Which in the case of damp spots usually means attracting water from the walls or air. Typically you’ll find the most popular substance is silica gel because it its relatively cheap whilst still being effective. (Silica is often what you’ll find packaged in with new shoes inside little white bags). Once they are full of water, figuratively speaking, they need to be re-charged. This usually involves gently heating the dehumidifier in a microwave for a certain amount of time to allow the water to evaporate, once complete they are ready to be used again.
- They do not need plugging in.
- There is no heavy tank to empty.
- They are available in a plethora of shapes and sizes. Making them ideal for small spaces such as cupboards or even for use in cars or caravans where it is not possible to plug in a powered dehumidifier.
- They are very cheap and can often be purchased for under £10.
- Not all can be re-used and are single use only.
- Are not suitable for excessive damp problems.
Peltier units are a very high-tech, albeit inefficient, way of going about the refrigerant model. Despite being virtually silent, their performance is quite weak and can be costly to run.
How they work:
An electrical current is passed through two different, layered, materials. Where the materials join a heat flux is created which draws the heat from one material to the other. This creates a cooler side for the water to condense upon. The water then drips away where it is collected/drained away.
- There are no moving mechanical parts so are quiet to run.
- Can be costly to run.
- Are typically not very efficient compared to other types of dehumidifiers.
What To Consider Before Buying
Typically you’ll need to consider 4 different criteria when buying a dehumidifier for your home:
By this I mean the size of the area to be dehumidified. For example, do you want to use it in a large area such as a big room or even a whole flat? If you do, then ideally you’ll need to use a refrigerant, desiccant model, which are ideally suited to work in larger areas.
Non-electric desiccant systems are simply not effective enough for anything over a small room or cupboard.Generally speaking if you want to use it in more than one medium sized room then a refrigerant model is ideal. However if you want to use it in a small space such as a side room or cupboard then a non-electrical desiccant could be a good choice (depending on how damp the room is).
Think about where you’ll place your dehumidifier and also how cold will it get? Are you placing it in an outbuilding or somewhere where the temperature get can get quite low? If you are then you will probably need to use a desiccant model. Refrigerant models have a problem with colder temperatures because the refrigerated coil is prone to freezing. This reduces the overall performance of the unit and in some cases may even cause it to stop working entirely.The is the opposite to desiccant dehumidifiers which can operate in much lower temperatures.
Placing a few non-electric desiccant dehumidifiers in a space which is very humid/damp is not going to show any significant results. This is because they simply do not have the capacity to absorb any where near enough water. Ideally they are suited to only small patches of mild humidity or confined spaces such as your car or cupboards.
However, if you have an very damp space an electric desiccant or refrigerant dehumidifier would have the capability to draw more moisture from the environment. It would also be a good idea to make sure that the water tank is relatively large. This will allow to dehumidifier to operate continuously without the need to frequently empty the tank.
We mentioned above that some models even come with a hose style attachment – which means they do not need emptying. This is much more ideal (if you have somewhere it can safely drain) for any areas with high levels of humidity, because you can literally leave the dehumidifier to work without needing to periodically empty the water container.
Well, price had to come in somewhere, and rightly so too. You need to make sure you are getting good value for money and that the running costs are not astronomical. This is particularly important in today’s world of rocketing energy prices.
Non-electrical desiccant systems are by far the cheapest to buy and do not have any parts which require maintenance or repair. They are also effectively free to operate because they do not require plugging in. That said, they do not have the capacity to work in large areas or deal with high levels of humidity. So, it would be false economy to buy one of these to solve large scale damp problems. They are however quite effective at reducing humidity in small spaces such as cars, caravans, cupboards and for helping with condensation in one room.
Recently Unibond have released one of the most effective non-electric dehumidifiers available called the Unibond Aero 360 pure. It has risen in popularity for this reason.
Peltier systems are very energy hungry and therefore can be expensive to run. They are cheaper to buy than refrigerant systems, but are probably not ideal if you require it to be running for extended periods.
Refrigerant systems typically come with a high price tag but are reasonably energy efficient to run. We use one of these in our house to help dry our our bathroom after showers in the winter (when we don’t want the window open, for obvious reasons!) and also to help dry our clothes. We often have it running for several days a week for pretty much for 10-12 hours and have not noticed any significant rise in our bills.
