Product Information

If you’re only planning to dehumidify occasionally – for a few hours here or there in a kitchen or bathroom, for instance – you can get away with a mini-dehumidifier with an extraction rate of less than one litre. It will be cheap to buy, cheap to run and perfectly effective. The same applies if you’re trying to fight damp or mould in a smaller area, such as a wardrobe, utility room or box bedroom. If you're on the hunt for a reliable dehumidifier, look no further than the Prem-I-Air 1.5L Ola Peltier Dehumidifier with Auto Shut Off Function. With its advanced thermo-electric Peltier module, this innovative device is efficient and effective at removing moisture from the air in your home. What sets it apart from other dehumidifiers on the market is its attractive design, making it a stylish addition to any space. Plus, it's the most portable option around, so you can easily move it from room to room as needed. Performance-wise it draws 350 Watts, making it one of the most powerful on this list at a competitive price. I tested it in my shower room, where I usually keep a window open to prevent mould. As the mornings get chillier this dehumidifier is the perfect replacement, keeping any mould at bay and the heating in. The auto-defrosting function also means it can carry on working when the temperature drops. The latest model in Meaco’s dehumidifier range is a compact version of the superb Arete One, dropping the extraction rate down to ten litres per day, but reducing the size of the unit to less than 50cm high. Not only is the Arete One 10L physically unobtrusive, but it’s also impressively quiet. While we measured noise levels of around 42dB with the fans running at full tilt, these rapidly decreased to well below 40dB, which is about as close as dehumidifiers get to silent. In its night mode, the Arete One 10L can go as low as 35dB. The recommended humidity for your home is 40-60 per cent in the summer months and between 30-50 per cent in the winter. You can measure it with a hygrometer (a humidity gauge - they’re not expensive). If it goes over 70 per cent, you run the risk of condensation, damp, mould, fungi and bacteria. That’s when you need a dehumidifier. Which is better, a compressor or desiccant dehumidifier?

The transparent water tank means I can keep tabs on when to empty it although it rarely needs emptying more than once a day. The dehumidifier also automatically switches off when the water tank reaches its maximum capacity of 2.1l. This EcoAir model can extract up to seven litres of moisture per day, and as a desiccant-type dehumidifier, it works at lower temperatures than your average refrigerant device. If you have a particularly humid environment, you can also connect a small drain hose to the bottom of the unit and have it empty out into a sink or wherever. All dehumidifiers do the same basic job of removing excess moisture from the air. However, there are three different technologies that do all the hard work.Domestic dehumidifiers can extract up to 25 litres of water per day. We have largely focused on 20l models since these are the most popular for domestic use. For larger spaces, damper environments or colder temperatures, choose something more powerful. (Or vice versa for smaller spaces.)

Look for one which draws less than 360 Watts and you will never spend more than 10p per hour. It’s often much less on lower power settings. Dehumidifiers are generally cheap to run. What size dehumidifier do I need? If you are worried about high running costs, choose the Meaco,” says Chris Wood, another expert from Aircon Centre. “It has a control system that can reduce your energy consumption by up to 80 percent compared to other dehumidifiers.” However, I wish the company would add two-factor authentication to its app. Midea 20 pint cube dehumidifier: Verdict

7. Meaco Dry ABC Range 12L Compressor Dehumidifier

Compressor dehumidifiers work in much the same way as a fridge or freezer. They draw in air and cool it, condensing any moisture as it passes across a refrigerated coil. The water then drips off into a water tank below, while the air is reheated and released into the room. Compressor dehumidifiers can be noisy and may use more energy than other types, although new compressor technology and refrigerants are bringing improvements on both counts. They’re most efficient at warmer temperatures of 20°C and above, and your best bet if you need to remove lots of moisture from a larger space. It’s slightly louder and consumes more power than the equivalent refrigerant, but can also run more effectively over shorter periods. That makes it a good bet for drying clothes or using in an outside office, garage or workshop where damp is becoming a problem, and it’s relatively lightweight and portable to boot.

With advice from air conditioning experts Ryan Kandola and Chris Wood and with help from others in The Telegraph Recommended team, I have tried and tested the best dehumidifiers on the market for energy efficiency, drying power, value for money and, where possible, quiet running. “Remember, size isn’t everything,” Ryan says. “Look at the area you’re dealing with and choose the right size of unit. You’ll be surprised at just how powerful some of the small dehumidifiers are.” High demand Keep it running all day long and the costs could mount up, but this is an excellent dehumidifier for situations where a refrigerant model just won’t work. Don’t get too excited about any claims of silent running – we found that, while actively dehumidifying, it puts out around 50dB on all of its three settings, so you won’t want to sit and watch the TV while it’s on. However, it’s a good performer for its size, reducing humidity in a damp-prone living room by 9% in the first hour and by nearly 22% within two hours. The laundry function’s quite effective too, helping dry your washing indoors without adding a layer of condensation to the windows. And at 9kg it’s light enough to take from room to room, making this a great dehumidifier for the average flat or small to medium-sized home. Peltier dehumidifiers also cool the air and condense the moisture content into water, but they do it using a cold heat-sink rather than a compressor. They’re not as effective as compressors, removing smaller amounts of water in a given time, but they’re quieter and more energy-efficient. Peltier dehumidifiers tend to be compact, lightweight units designed for smaller spaces.It’s simply a matter of setting the desired humidity level and the unit will do the rest. What you will need to do is empty the water tank from time to time. Where should you place a dehumidifier? The cost of one kiloWatt-hour of electricity is capped at 27p under the Energy Price Guarantee as of October 2023. Although prices do vary by region and contract (economy 7 tariffs are more expensive by day and cheaper by night, for example), we use the capped price to estimate running costs.
