Continuous-drain facility Many dehumidifiers allow you to connect a hose and flush the collected water away to a low-level drain. This will save you having to empty the water tank, or prevent the machine from getting full and switching off if you're not around to empty it. Note that dehumidifiers with this function often don’t come with a hose in the box, so you’ll probably have to buy it separately. One thing of unique importance for dehumidifiers is the size of the tank. A dehumidifier with a large demoisturising rate becomes a hindrance if the tank with which water is captured is insufficient in size. Determining how frequently you want to use your dehumidifier is of paramount importance in this regard. Simple and standard, the only additional feature is that you can choose between their four pre-set humidity levels to match your and your home's needs. All you’ll need to do is pop it in a corner and let it run, it costs around nine pence an hour so that it won’t break the bank, and when it is full, the dehumidifier will automatically shut off to avoid spillage. The only downside is that at 47dB, it is between a whisper and a regular voice; it is a little noisier than its competitors, so we recommend keeping it out of the bedroom at night. Remember that to maintain your dehumidifier’s airflow, you should never place it too close to a wall or any furniture, and ensure that you keep it away from electrics in case of leaks. What is the best time of day to use a dehumidifier? The PB-15-UK is a refrigerant dehumidifier. It's one of the biggest models we've reviewed, with a bulky footprint and a very heavy 17kg design. In other words, it's not the right tank for a small flat or home!

What does a dehumidifier do?

Wheels/castors These could come in useful if your dehumidifier is heavy – they can weigh from 6kg to more than 16kg. If you have a serious damp or condensation problem, it’s worth buying a model with a bigger tank so that it keeps working all night. How to choose the best dehumidifier for your home

Small, portable and whisper-quiet thanks to Peltier technology, you can keep this sleek-looking dehumidifier on your nightstand or dresser and let it run all night without you even noticing. Although, if you are light-sensitive, we suggest covering up the glowing light! Removing up to 300ml of water, the Silentnight Dehumidifier works all day and all night to improve your bedroom's humidity and simultaneously filter out allergens (perfect for those with hay fever!). Then when the light goes from green to orange, just empty the tank, and start it up again. It's simple, easy to use, and the best dehumidifier for your family's bedrooms! The Dimplex DXDH16N Dehumidifier is the master of big spaces; don’t leave a large room to a dehumidifier that’s not designed for the job at hand. The size of the dehumidifier, your source of power, and the intensity applied in dehumidifying the air are the major efficiency determinants. However, energy efficiency cannot be determined from these factors alone. Key specs – Dehumidifier type: Desiccant; Tank size: 2l; Extraction rate: 6 litres per day; Dimensions: 48.5 x 29 x 17.5cm; Weight: 6kg; Warranty: 2 yearsA dehumidifier designed for small rooms is probably not going to work well in a large room, and a dehumidifier designed for large rooms is probably overkill for a small room (with perhaps the exception of a dehumidifier that has variable power settings). Essential Factors to Keep in Mind In addition, the air purifier uses a five stage system to control odours and remove allergens. This includes charcoal, anti-allergy and ionisation stages. If you or someone in your household suffers from allergies, the air purifier could help relieve symptoms. We also like how the charcoal and deodouriser stagesreduce nasty odours that can build up in homes. As a desiccant model with an 8 litre per day capacity, the Zambezi is more effective incooler temperatures than refrigerant models. At 10 degrees Celsius, for example, it's able to extract up to 7.5 litre per day depending on humidity. This makes it suitable for garages, conservatories and other cooler areas.

Other features include automatic shut-off when the water tank is full, a continuous drainage option and three options for humidity control. There are also two fan settings and a laundry function. Emptying the tank is simple, although you'll need to replace the filter every 4-6 months. Choose the right capacity for the size of your space, the number of people living in it and the severity of your damp problem. So, why choose this one? Firstly, it's smart; using an app from your phone, you can control it from anywhere, even on the school run or while at the supermarket. You can even connect it to your Alexa or Google Home to operate it with the sound of your voice! Secondly, it is powerful; with the ability to extract 25L of water from the air and a six-litre tank capacity, you can rest easy knowing that this dehumidifier has your damp under control. Thirdly, although its power usage is much higher, it is super energy efficient; ElectriQ claims it is 50% more efficient than other standard dehumidifiers. We love that for our energy bills! Lastly, for the price, this dehumidifier doesn’t just control your home's humidity. It also purifies the air and eliminates terrible odours using a combination of UV sterilisation, an active carbon filter and a HEPA filter. In short, it works hard to keep you and your family feeling fit and healthy!We're impressed that it can extract up to 12 litres per day, especially considering the low price. However, considering thetwo litre tank, we wouldn't recommend this for large houses. For small houses, student accommodation or flats it's an excellent choice. Some (but not all) dehumidifiers have an auto shut-off feature that will cease operation upon a water tank reaching capacity. The auto shut-off feature will prevent flooding and damage to your equipment. Fan speeds: Some dehumidifiers have just one speed for continuous drying, limiting your control. Whilst others have up to three, which is advantageous if you want to adjust it for faster drying or put it on a lower (and possibly quieter) setting.
