If you’d like to control the moisture in your home effectively, there are lower-powered modes and a super-quiet mode that still draws an impressive amount of moisture out of the air. This device is one of the most compact models on our shortlist - 15 x 13 x 21 cm. Its weight is not too big as well, and even when the 500 ml reservoir gets full, you will be able to carry the dehumidifier from one place to another without much effort. On top of that, you can place it on any surface: the non-skid feet ensure its stability.

At the other end of the spectrum, the most powerful dehumidifiers can have capacities of up to 25 litres per day. Meaco, for example, produces the excellent Low Energy Dehumidryer with a 25 litre capacity. As you would expect, the largest capacity models tend to be more expensive. That will be especially useful over the winter months as it means you won’t have to keep your heating on as long to dry your clothes, reducing your energy bills in the process,” says Wood. It still removes a surprising amount of water from the air though. If you have a small space that’s suffering from mould, condensation or just uncomfortably high humidity, the PB-02 can certainly help. The lightweight design also makes it easy to move around the house to where it’s needed most.

If you are worried about high running costs, choose the Meaco,” says Chris Wood. “It has a control system that can reduce your energy consumption by up to 80 percent compared to other dehumidifiers.” AUTOMATIC SHUT OFF & 24Hrs TIMER: Automatic shut off safety feature for preventing overheating of compressor and overflowing water. Dual fan speeds and 24 hour timer function. It's also important not to confuse the extraction rate with a dehumidifiers water tank capacity. As both are generally measured in litres or millilitres this can sometimes cause confusion.

Peltier dehumidifiers – sometimes called thermo-electric– remove moisture differently to compressor or desiccant models. Electricity is used to create a temperature difference, causing one side of an internal element to heat up and the other to cool. As warm and humid air enters the machine, it first reaches the cooler side, causing moisture to condense and drip into the tank below. It’s probably obvious that the larger the room(s), the greater capacity you’ll need. Rooms with severe damp problems also require larger capacities. Signs of severe damp include stains on walls, condensations on walls and, in the worst cases, wet floors. However, when you combine these features with the several modes available, the quietness and temperature range that this dehumidifier works in, you’ll be amazed.This model is one of the most compact dehumidifiers you can find (22 x 15 x 13 cm) and, because of that, it has a relatively small water tank - only 0.5 L. But considering that the manufacturer states that the maximum water extraction per day is around 250 ml, you will have to empty it only once in two days. Plus, like its more advanced rivals, this device also has an auto shut-off when it is full. As we mentioned before, this model is very easy to move around. Thanks to that, you will be able to control the humidity level all over your house. The model is suitable for use in the bedroom, bathroom, garage, and other rooms. The top row is the size of the room or environment you want to dehumidify. The first column is how much moisture the room contains. Environment Conditions The beauty of a desiccant dehumidifier is not only that they are typically quieter than compressor models, but they are ideal for smaller, unheated areas such as conservatories, campervans, garages, boats and cellars. They’re also fantastically efficient. Dehumidifiers originally had a compressor to help extract moisture, using a similar technique to refrigerators and air conditioning. This type of machine has an array of pipes through which coolant is circulated constantly by the compressor.

If you’re looking for a small dehumidifier, then the Russell Hobbs RHDH1061G Portable Dehumidifier is about as compact as it gets, measuring just H22 x W14 x D14cm and weighing in at 0.9kg. As the air cools, the water vapour condenses on the cold surface of the coil and this is collected in a water container. Always use exhaust fans in your kitchen and bathroom while cooking and showering. If you haven't got fans, you can simply open the window to let fresh and dry air in. A dehumidifier's extraction rate is an average of how much moisture it can remove from the air during a given timeframe. Most commonly this is measured in litres per day, so an extraction rate of 10L/per day means the dehumidifier should be able to extract 10 litres of moisture within 24 hours if running continuously. In practice, this also depends on the humidity levels of the room, and the ambient temperature.

A downside is that there’s no option for continuous drainage. If you want a dehumidifier that can run for extended periods without human intervention, the Pro Breeze isn’t the right option. Portability If the humidity levels are overly high, you might notice too much condensation around your house, especially on your windows. Also, the humid air might travel through your walls and ceilings, thus causing mildew on your clothes, peeling paint on your walls, and rot in woodwork. And to lower the humidity in your home, you can, of course, turn on a dehumidifier. But if you don’t have one, you can: All dehumidifiers use a fan to draw moist air in through a grille at the front of the machine. The moisture is then extracted from the air and the dry air is heated, although the method of doing this varies between the different types of machine. The dry and warm air is then expelled using the same fan or a different one. As you might expect, this is considerably lower than refrigerant or desiccant dehumidifiers. Even the cheapest desiccant models can extract up to 6 litres/per day in the right conditions, so the Pro Breeze dehumidifier is only suitable for small rooms and mild humidity. With that said, the low price means you wouldn’t expect it to match full-size dehumidifiers. It’s a lot cheaper and smaller, so it’s unfair to compare it with models costing five times more.

The first factor is the amount of laundry that you are trying to dry. A larger load of washing will have a greater amount of moisture that needs to be removed, which naturally takes longer.COMPACT ANTI-MOULD AIR CLEANER: Assists in the relief of allergies, breathing difficulties, congestion, and itchy watery eyes by reducing mould spores and dust mites from living, work, or play areas.
