In reality, it’s probably a little too powerful for my needs, instead I’d recommend it to anyone with large, open-plan rooms in their houses or a big house with open doors, where it can sit in a hallway. While the power of 290 Watts means it only costs around 8p per hour, there are still lower energy options on this list that anyone with a smaller house or flat should consider. Buyers should match the litre capacity with the size of the room or basement that the unit will be situated. When in a smaller space, then a 10-litre daily capacity may be fine. In other situations, 20-liters is a possibility. Also, bear in mind whether you’ll possibly use the dehumidifier not just in the basement but also in other rooms of sizes. In which case, a larger litre capacity wouldn’t go a miss to cover all requirements in a single unit. High Humidity vs. Low Humidity We explain this below to make it clear which is which and where they’re best used. Refrigerant Dehumidifiers

The compressor is one of the most likely components to develop a fault. If it stops working, the machine can’t extract water until professionally repaired. Desiccant machines don’t have a compressor, which is one less thing to go wrong. 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. A desiccant dehumidifier is based on using absorbent material. This alone will extract moisture from the air that passes through the unit. The material is then warmed up to remove the collected water that flows into the collecting tank (or out through a hose in some models). We like that this mini dehumidifier can be used in smaller, modern-style houses with bathrooms that have no windows. When you rely on noisy extractor fans for internal bathrooms, it can disturb family members and children when used during the night. Running this mini extractor fan will keep the bathroom damp and odour free while running almost silently.Refrigerant fluid is essential for a dehumidifier to extract water from the air. While the refrigerant should be in a closed system so it doesn’t run out, the reality is that small leaks can sometimes develop. It comes with a 10.5-litre daily capacity to remove moisture from the air down to the same 1-degrees Centigrade and up to an improved 40-degrees (over the 35-degrees of the DD1 model).

Nearly all dehumidifiers have a continuous drainage option. This allows water to run away via an external pipe into a drain or sink, rather than filling up the machine’s water tank. The power usage depends on the mode too. It varies from 420-watts to 735-watts. Also, the model weighs in at 7.5-kilograms and has a fold-away carry handle too. Convert Cubic Feet Per Hour to Cubic feet per minute. To get the CFM, cubic feet per minute, (which is how these machines are rated), we’re just going to divide that number by 60 (sixty minutes in an hour, right?). This comes out to 1,000. So that’s it! There is a 2-litre water tank included and a continuous drainage option via the 1-metre hose supplied in the box. The automatic shutdown feature when the water tank is full is convenient. Also, unusually, an alarm comes on to notify you when the unit has been tipped over and could be a water leak hazard. Overall, when wanting a smaller capacity dehumidifier for a modest-sized basement and needing a quiet one too, then this model is perfect. The energy-efficiency is also impressive. Lastly, it’s no slouch in the moisture collection department and cleans the air quality while it’s at it too.The device struggles to work effectively in rooms larger than 20 square metres, so if you want to dehumidify a room and the door or window is left open, you won’t get the results that you desire. If you live in a household where you leave most of your internal doors open for most of the day, consider a larger dehumidifier that can cope better under these conditions. It has the capacity of 1500 melilites, and it is capable o removing up to 500 milliliters of moisture in a day. It has an ultra-quiet noise system which will change your life easy and quite comfortable. The Dehumidifier’s product dimension is 22cm long, 16cm wide, and 30cm high. The total weight of it is 1.85 kg. The other controls let you choose between quiet Sleep mode, powerful High mode for laundry and economic Low mode for daytime use. You can fine-tune these by setting the fan speed and desired humidity level (you’ll want it under 50 percent, see below). But that’s it. Very much a fire-and-forget machine. I like the way it looks, too. Although it’s an American company, there’s something reassuringly Swiss about it. Maybe that’s just me. Let’s put those 2-4 air changes per hour into a real-life scenario. Assume you have some sort of structure that is 30 feet X 25 feet X 20 feet. To calculate the size dehumidifier required is simple… UGHEY Dehumidifier uses a technology called Thermo-Electric Peltier tech. It uses temperature difference to make the dehumidifying element to condense air moisture. This Dehumidifier does not need to use any compressors, which creates unnecessary noise for using this Thermo- Electronic Tech.
